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

 Locust tree, and often proves very destructive in the Middle 

 and Western States. Tiie}^ are flat, the body beliind being- 

 broad and square, and tlie el3'tra are generall^^ ridged and 

 furrowed. 



Casskla auriclialcea Fabr., tlie 3'ellow Ilehnet beetle, is hem- 

 ispherical, flattened, so that the edges of the wings are very 

 thin ; and the larva is broad, oval, 

 flattened, and b}- means of two spines 

 terminating its upturned abdomen, 

 holds its old cast larva skin over its 

 Ixxl}^ as a means of protection. Dur- 

 ing the last week in July we have 

 found the larvie in all stages of 

 growth A'ery abundant on the IMorn- 

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

 j^oung the head and legs are more prominent than in the old. 

 It i)upates the last of Jul^^ and early in August. 



The Chebjmorpha cribmria Fabr. (Fig. 49G ; a, pupa) we 

 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 auriclialcea, not only in its 

 greater size, but the bod}^ is thicker and narrower ; the head is 

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

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

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

 b^' a silken thread, a few segments from the end where the 

 end of the body of the future pupa is situated. 

 ^) i^^c^ It is .45 of an inch long. The pupa is broad 

 and rather flattened, dark and spotted with 

 rir-. 407. yellow and covered with a Avhitish powder, 



causing the vellow portions to appear more prominently- ; along- 

 each side of the abdomen is a row of live spines, and there are 

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

 an inch in length.
