LEPIDOPTERA— PAPILIONIDAE— NEOPHASIA MENAPIA. 743 



ities, where they can better conceal themselves in the herbage for the night, 

 and where the general color given by the vegetation is more brown than 

 black. 



At the higher elevations the species appears later in the season, and at 

 12,000 feet may be found until the last of August. 



The eggs are laid on Scdum; in shape they are flattened spheres, above 

 with a small conical depression, in the center of which is the micropyle. 

 The egg is chalky-white, and to the naked eye seems covered with little 

 granulations, except a smooth round spot below, which is the surface of 

 attachment to the plant. 



The eg-gs do not hatch until the following spring, when a hole is eaten 

 through the side of the egg by the larvee. At first these are black, with 

 a few bristling hairs. The adult caterpillar is not known, but probably 

 resembles that of allied European species in being smooth and nearly black, 

 with orange dots.

This species was brought by the expedition from Southern Utah ; 

 specimens have been taken in Montana, but the proper home of the species 

 seems to be nearer the Pacific coast. It has not been found in Colorado.

 Weophasia Mcnapia, Edw., Butterflies N. A., i. 



This western species was taken in some numbers in Colorado by the 

 Allen expedition of 1871. They were found early in August, but the pre- 

 cise locality I do not know. Colorado specimens have the outer half of 

 costal margin of secondaries tinged with vermilion in the male. This, I 

 believe, is not shown by Californian examples. 



The larva is unknown. I copy the following description of the chrysalis 

 of N. Menapia, from a very interesting paper by Henry Edwards, esq., on 

 the Early Stages of Pacific Coast Lepidoptera, published in the Proceedings 

 of the California Academy of Science for 1873: — 



''Chrysalis. — Very long and tubular, with the beak sharply pointed ;
