their burrows." Hispa (Uroplata) suturaUs Fabr. mines the 

 Locust tree, and often proves ver}^ destructive in the Middle 

 and Western States, Tliey are flat, the body behind being- 

 broad and square, and the elytra are generally ridged and 

 furrowed. 



Cassida aurichalcea Fabr., the 3-ellow Helmet beetle, is hem= 

 ispherical, flattened, so that the edges of the wings are ver^- 

 thin ; and the larva is broad, oval, 

 flattened, and by means of two spines 

 terminating its upturned abdomen, 

 holds its old cast larva skin over its 

 bod}^ as a means of protection. Dur- 

 ing the last week in July we have 

 found the larvte in all stages of 

 growth very abundant on the Morn- 

 ing-glory in our garden, eating holes in the leaves. In the 

 young the head and legs are more prominent than in the old. 

 It pupates the last of July and early in August. 



The Chelymorplia cribraria Fa])r. (Fig. 49G ; o, pupa) Ave 



have found in all its stages on the leaves of the silk-weed late 



in July and early in August, and in one instance in Salem it 



occurred in abundance on the leaves of the raspberry. The 



larva differs from that of Cassida aurichalcea, not only in its 



greater size, but the body is thicker and narrower ; the head is 



freer from the thorax, and the spines are simple, not spinula- 



ted. The body is 3ellow and less protected by the cast skin. 



When about to transform, the larva attaches itself to the leaf 



by a silken thread, a few segments from the end Avhere the 



, , „ , , end of the body of the future pupa is situated.

'^'^^^^'Wp^ and rather flattened, dark and spotted with 



Fijr. 407. 3'^ellow and covered with a Avhitish powder, 



causing the yellow portions to appear more prominently ; along 



L^ach side of the abdomen is a roAV of five spines, and there are 



four spines on the anterior edge of the prothorax ; it is .40 of 



an inch in length.
