Family THYRIDiE. 



Small but stoutly built species with small, short, more or less angulated 

 wings which are black or brown in color, with white or yellow semi-transparent 

 spots The antennae are strictly thread-like or a little thickened in the middle, 

 and the insects have the habit of flying about bare or sandy places, quite early 

 in spring. Very little is known of the early stages save that they are not 

 injurious.

PLATYTHYRIS G. and R. 

 P. oculatana Clem. Delaware Water Gap (Pm). 



Family SESIIDiE. 



Species of moderate or rather small size, often quite stoutly built, the wings 

 narrow and as a rule at least one pair in great part transparent or without 

 scales. Quite a number have both pairs practically without scales, and, as they 

 are usually more or less black, banded with yellow, they closely resemble wasps 

 or hornets. The antennae are usually spindle shaped and have a little tuft of 

 hair on the tips. In the male they are often pectinated. 



The larvae are borers without exception, living in the stems, trunks, roots or 

 branches of living trees, sometimes causing serious mischief. 



In this family the list has been looked over by Mr. Beutenmuller, who has 

 made it a special study. 



MBLITTIA Hbn. 



M. satyriniformis Hbn. = ceto West. Common from July to September 

 wherever squashes or other cucurbits are grown ; the larva being the well-
