Analysis of about 69,000 Trichoptera from Arkansas and Missouri resulted in identification of six species previously unknown from Arkansas (i.e., Agraylea costello, Neotrichia collata, Orthotrichia curta, Oxyethira glasa, O. pescadori, Neureclipsis piersoni) and three species previously unknown from Missouri (i.e., Cheumatopsyche mollala, Hydroptila broweri, H. poirrieri). Of those species, Agraylea costello, Hydroptila poirrieri, Orthotrichia curta, Oxyethira pescadori, and Neureclipsis piersoni represent new records for the Interior Highlands. Males possibly representing Ceraclea enodis, not previously recorded from the Interior Highlands, were found in both states. An undescribed species of Neophylax (family Uenoidae) from Saline Co., AR, is discussed. Informative distributional information is provided for an additional 61 species known from the Interior Highlands.

Thirty-two species of Miridae are recorded for the first time from West Virginia. With an additional six species reported in the literature and two subsequent synonymies since the 1983 “Annotated List...” by Wheeler, Mason, and Henry, 283 species of Miridae are now known from the state. The new records include six species in the subfamily Bryocorinae, two in Cylapinae, two in Deraeocorinae, twelve in Mirinae, seven in Orthotylinae, and three in Phylinae. Locality information, specific dates, associated host data, and number of specimens and sex are given for each species. Names used in the previous 1983 list are updated.

Coccinella septempunctata L. is a widespread Palearctic species that has been introduced several times into North America within the last century. It is generally considered monomorphic with seven elytral maculae in North America. In this paper, we document variation in elytral macular patterns of C. septempunctata based on examination of 674 (567 North American and 107 Palearctic) specimens of C. septempunctata and 382 digital submissions of North American C. septempunctata. Two beetles lacked apical maculae, and 18 beetles had paired humeral markings. Humeral markings were consistent in position and typically had less-dense black pigmentation than maculae. Sixteen of the 18 beetles with paired humeral markings were from 11 states in the United States, one was from Alberta, Canada, and one was from Italy. Some specimens had asymmetrical elytral markings that included pock marks, irregular fuscous markings, or both. Nineteen specimens of C. septempunctata (19 North American, 1 Palearctic) and 16 C. septempunctata in digital images had asymmetrical markings. Some beetles with paired humeral markings also had dark pock marks or irregular fuscous markings. We recommend examining additional C. septempunctata from various locations to accurately estimate frequency and pattern of variation in elytral macular forms. Possible causes and implications of variation in the elytral maculae of C. septempunctata are discussed.

The South Asian rove beetle Rugilis ceylanensis (Kraatz) is reported for the first time from North America based on collections from two Canadian provinces and 14 U.S. states. This paederine staphylinid represents the fourth adventive Rugilus species documented in North America. It also is reported new for Hawaii. North American records are mapped, and a diagnosis, brief description, photographs of the adult, and line drawings of the male genitalia and associated terga and sterna are provided to facilitate its recognition among the Nearctic Rugilus fauna. A lectotype is designated from the syntype series for Stilicus ceylanensis Kraatz.

Euscelis ohausi Wagner, a Palearctic deltocephaline leafhopper found mainly on Scotch broom (Cytisus scoparius; Fabaceae), was reported new to North America in 1971 based solely on late-instar nymphs from one locale in Oregon. We now confirm its establishment in North America based on collections from nine localities in Oregon, three in Washington, and four in British Columbia (first Canadian record). United States records are listed and mapped, and the adult is briefly described and illustrated. Characters are provided to distinguish E. ohausi from other species of the genus occurring in North America.

A new species of eastern Nearctic Ameletus, Ameletus janetae Kondratieff and Meyer, is described from Hardy Co., West Virginia. The ventral plate of the male penis of the new species is most similar to Ameletus tarteri Burrows but can be distinguished by a single spine of the ventral plate greatly reduced and only armed with 2–3 small denticles.

Monolepta ongi , n. sp., is described from Lanyu Island, Taitung county, Taiwan. Its allied species, Monolepta longitarsoides Chûjô, 1938, is redescribed for comparison. Their antennae, male aedeagus, female spermatheca and bursa-sclerites are illustrated. The lectotype and paralectotypes are designated for Monolepta longitarsoides from Chûjô's type series.

Orius diespeter Herring was described in 1966 based on two specimens collected in western British Columbia, Canada. The original description relied mainly on color of the hemelytra to distinguish this species from Orius tristicolor (White), a related species common in western North America. Orius diespeter is shown here to have variation in color; hemelytra coloration ranges from entirely dark, to dark with contrasting white on the basal half of the corium. Specimens of O. diespeter with white markings are easily confused with O. tristicolor. Orius diespeter is separated from O. tristicolor by having shorter dorsal setae, a shorter copulatory tube, and a shorter flagellum of the paramere. The distribution of O. diespeter in North America is updated to include most of the northern states of the United States, as well as western and southeastern provinces and territories of Canada. We suggest that early to mid-1900′s records for O. tristicolor in the northeastern United States and eastern Canada actually refer to O. diespeter.

Denierota juarezi , new species, is described from the Sierra Madre del Sur in Guerrero, Mexico. The only other congener, D. kraatzi (Haag-Rutenberg), is allopatric and ranges from Chiapas into Central America. The new species differs from D. kraatzi primarily in the structure of the male trochanters and pygidium.

Replacement names are proposed for three primary junior homonyms within the hemipteran family Plataspidae: Coptosoma parapallens replacing C. dilutum Linnavuori, 1977, C. cachani replacing C. transversa Cachan, 1952, and C. jensonhaarupi replacing C. pygmaeum Jensen-Haarup, 1926.

Pseudococcus saccharicola Takahashi was collected on Guana Island, and nearby Beef Island and Tortola, in the British Virgin Islands (BVI). The records are the first in the Western Hemisphere for this potentially important Old World pest of sugarcane and certain other graminoid crops. Host plants on Guana were Chloris barbata Sw. (swollen fingergrass), C. radiata (L.) (radiate fingergrass), Cynodon dactylon L. (bermudagrass), and Saccharum officinarum L. (sugarcane). A probable mealybug predator associated with colonies of P. saccharicola on all three islands was the hyperaspidine coccinellid Hyperaspis scutifera (Mulsant), previously recorded in the West Indies only from the Leeward Antilles (Curaçao). Both the mealybug and lady beetle are considered adventive in the BVI. Diagnoses and illustrations of both species are provided to facilitate their recognition. Hyperaspis sanctaeritae Dobzhansky, 1941, described from Arizona, USA, is proposed (by N.J.V.) as a junior synonym of H. scutifera (Mulsant 1850).

The female genitalia of Caltoris bromus bromus (Leech), Caltoris cahira austeni (Moore), and Caltoris cormasa (Hewitson) are described and illustrated. Caltoris kumara kumara (Moore) is reported as a new record to China. A key to the Chinese species of the genus is provided.
