Since the publication of the Catalog of the Aphid Genera Described from the New World (Favret et al. 2008), several errors and omissions have come to light. We here make corrections to seven genus-group names and add 17 valid and nine invalid generic names, raising the total number of available New World genus-group names to 232. Future nomenclatural additions and corrections, at any aphid taxonomic level, will be published in the Aphid Species File database ( http://aphid.speciesfile.org).

An extensive review of published record data, and the amassing of new collection data from the study of numerous collections and surveys has led to the accounting of 182 species of Ephemeroptera from the state of South Carolina. Previous listings are corrected, and all species are supported by previously available or, for the most part, new collection data. Twenty-two species are listed for the state for the first time, and supporting data are provided for the first time for another 39 species. Three species previously listed for South Carolina are discounted. Over 1000 new county records are given for 160 of the species and all 46 state counties.

The mayfly fauna of California consists of 155 species in 44 genera among 15 families. Previous data and new data (from 23 major collections) are given for all species and include first published state data for 53 of the species. In addition, 1,720 new county records involving all 58 California counties are given for 140 of the species. Less than 10 percent of the species appear endemic to California

Stream sampling on the island of Martha's Vineyard and in southeastern mainland Massachusetts produced 154 species, when added to other records, 157 species have been documented, including 47 new state records. Unaltered streams on Martha's Vineyard are cold water streams with temperatures similar to streams at higher elevations in New England. Extended seasonal larval presence of several species was noted on Martha's Vineyard.

The family Roeslerstammiidae is recorded from Mailand China for the first time, including one new record genus, Agriothera Meyrick, 1907, and two new record species, Agriothera doipakiae Moriuti, 1987 and Agriothera issikii Moriuti, 1978. The wing venations of these species are illustrated for the first time. A key to the species of this family from Mailand China is also presented.

Two new Asilidae species, Psilonyx flavicoxa sp. n. and P. dorsiniger sp. n. are described from China. A key to the Chinese Psilonyx is given in the present paper.

A new procedure for clearing eggs belonging to genera of Ceratopogonidae is described. In the new procedure eggs in different states, with different ultra structures of the exochorion, were immersed in 10% glycolic acid (CH2OH-COOH) and 20 % mandellic acid (C6H5.CHOH.COOH) for 1–4 minutes. Eggs, prepared by both acids and subsequently neutralized by distilled water, were placed in a saturated solution of phenol, and then passed through a battery of alcohol solutions. Finally, critical point was performed and gold metallized. After preparation the eggs of this group retained their natural form under vacuum long enough to yield good microphotographs of the outer layer of the chorion.
