Genus LYCORINA, Holmgren. 



Before seeing Holmgren's descri])tion of this genus I had 

 referred (in MS.) the species described below to a new genus which 

 I had named Toxophoroides, from the resemblance in form to the 

 Dipterous genus Toxophora. Not feeling sure tluit the species 

 in question belongs to Lycorina, I add a description of the form 

 and sculpture. 



Head subtransverse ; clypeus small; face flat ; eyes large, ovate; 

 ocelli large, prominent ; occiput and cheeks flat; antennae long, 

 slender, filiform ; thorax short, robust, gibbous ; mesothorax long, 

 subconvex ; scutellum protuberant, convex ; metathorax very short, 

 abrupt behind ; prothorax and pleura excavated ; wings without 

 areolet; legs slender, ungues cleft; abdomen sessile, depressed, 

 first segment longer than broad, remaining segments transverse, 

 second, third, and fourth with a median, triangular-shaped, deeply 

 impressed line inclosing a smooth, convex, triangular space; ovi- 

 positor long, exserted from extreme ti[) of abdomen.
