shield sometimes considerably darker than the body. Light colored 

 hairs arising from minute dark spots on slight elevations sparsely clothe 

 the body. The three pairs of true legs borne by the thoracic seg- 

 ments are black; the five pairs of pro-legs are of a fleshy nature and 

 borne by the fourth, fifth, sixth, seventh, and last abdominal segments. 



The pupa. — This is the quiescent stage through which the insect 

 passes in changing from the larva to the adult. If the nests made by 

 the larvse be examined in the latter part of June the pupse may be 

 found in a tube of dead leaves. Fig. 2, a and h represent in outline 

 the ventral and dorsal aspects of the pupa. It is about .27 of an inch 

 (7 mm.) in length and of a light brown color. Each segment of the 

 abdomen is provided on the dorsum with two rows of small tooth-like 

 processes pointing caudad, and there are several hook-like bristles pro- 

 jecting from the caudal segment.

head, thorax, and basal third of the fore wings, and also the outer 

 edge and fringe, are dark ashen gray, the middle of the fore wings is

 some specimens this part is ashy gray, but little lighter than the base. 

 Just before the anal angle are two short ^horizontal black dashes fol-
