which is more or less well defined; the shoulders are covered 

 with brown scales becoming diffused posteriorly in the yellowish 

 scales. The pleura are brown with small spots of grayish white 

 scales. The legs are wholly brown with the under side of the 

 femora yellowish white ; the small dot at the- knee is almost im- 

 perceptible. The claws are precisely as in C. pretans, those of 

 the anterior and mid feet unequal, the larger with a median and 

 basal tooth, the smaller with a single tooth near the base. The 

 male posterior claws and all those of the female are equal, each 

 with a sing'le median tooth nearer the base. 



The abdomen is dark brown with basal bands of dirty white ; 

 in the female these bands are narrow and widen out laterally ; be- 

 neath, pale brownish with scattered white scales, especially no- 

 ticeable in the apical segments ; in the male the bands appear 

 darker, being mixed with some brown scales. They are narrow- 

 on the anterior segments, broader on the posterior and widen out 

 laterally as in the female; beneath it is whitish AA'ith mixed brown 

 scales. 



Habits of the Adult. 



This species was bred once only and four examples representing 

 both sexes were obtained. They were determined as reptans by 

 Mr. Cocjuillett. but are undoubtedly different from the other 

 specimens caught and bred and labelled with the same name. 

 The species was described by Mr. Grossbeck at my suggestion. 



Description of the Larva. 



Note. — The lar^•ce frcjm which this species was bred began to 

 die off in the breeding jar before it was known that we had a new 

 species to deal with. Then, only C. syh'cstris larvie were left 

 alive; but remnants at the bottom of the jar were placed in al- 

 cohol. In these remnants only the more stronglv chitinized parts 

 of the larvcTS remained, the anal siphon and the head case ; the 

 antennal attachments seem to offer but little resistance to de- 

 composition ; only one head retained them and these were in such 

 conchtion as not to alknv a drawing to be made. 



The larvae present a general resemblance to C. sylvestris, but 

 are much smaller. The mandibles and maxillary palpi are also 

 similar to that species, but the sides of the mentum are more 

 rounded and have fewer teeth — ten or twelve <^n each side of the 

 apex (fig. 93, 5).^ The hairs of the rotary mouth brushes are
