magnified tlian the others (fig. 10). The eggs and young larvre have 

 recently been described for the first time by Miss Kimball (1. c), and 

 this summer a large number of specimens in all stages were received 

 from the West, from which the accompanying figures were made. 

 From these specimens many eggs were obtained, and later, larvse. 



The cone-nose is a rather large insect, measuring an inch in length 

 and characterized by a flattened body and very narrow, pointed head 

 and short, strong beak. In color it is dark brown, with the light areas 

 indicated in the figure pinkish. Its " buggy" odor is even more intense 

 than that of the bedbug. It is a night flyer and is attracted into open

windows by lights. It conceals itself during the day under any loose 

 object, often leaving beds which it may have frequented during the night. 

 The adult is not apt to take flight, but can run rather swiftly. 



The eggs are white, changing to yellow and pink before hatching, and 

 of the i)eculiar shape indicated in the illustration. The young hatch 

 within twenty days. There are at least two larval stages (fig. 11, a, h) 

 and two pupal stages (fig. 10, «, h)^ the latter characterized by the pres- 

 ence of distinct wing pads. In all these stages the insect is active and 

 predaceous. The eggs are normally deposited and the early stages are 

 undoubtedly passed out of doors, the food of the immature forms being 

 other insects. The eggs which may be dropped indoors must fail 

 normally to mature adults, and in fact immature specimens are rarely 

 found indoors, and the wingless and rather sluggish larv« and pupae 

 would have little opportunity of reaching the higher animals under any 

 circumstances. It winters, both in the partly grown and the adult
