Tribe VII. EPILACHXIXI. 



This tribe is represented in the United States by two or three 

 large pubescent species, belonging to the single genus Epilaclma. 

 They have the margin of the elytra rather strongly reflexed; epi- 

 pleurae horizontal, broadly concave: legs moderately retractile: 

 tarsal claws cleft, the lower cusp being nearly as long as the upper 

 one. One species occurs sparingly in southern Indiana.

dian line, the basal the larger, and one at each side near the margin. Ely- 

 tra each with seven black spots, three sub-basal, three median and one sub- 

 apical, the last named the largest ; the inner sub-basal and median on each 

 side uniting to form two common sutural spots. Metasternum blackish, legs 

 pale. Length 7-8 mm. (Fig. 197.) 



Orange, Perry. Crawford and Posey counties; frequent, April 

 9-Xovember 9. Taken beneath bark in early spring and late fall, 

 and at other times on foliage. Hibernates in large colonies beneath 

 leaves in low ground. This insect, known as the "squash lady- 

 bird," presents a remarkable exception in food habits to other mem- 

 bers of the Coceinellida?. the larvae being herbivorous and feeding 

 upon the leaves of pumpkin, squash and allied plants. It is yel- 

 low, armed with forked spines, and feeds upon the lower side of the 

 leaf, while the adult usually feeds upon the upper surface. They
