Abstract

The egg and larval stages of Mylassa crassicollis (Blanchard, 1851) are described and illustrated. The eggs are stalked and covered with fecal matter forming an egg case. The larvae live inside a case and the larval stages differ in microsculpture and head capsule chaetotaxy. We discuss the inclusion of Mylassa Stål in the Cryptocephalini subtribe Pachybrachina.
