LEPIDOPTERA, 325 



tenths of an inch. The moths of the genus Crambidia can 

 be recognized by the fact that veins Vj and V3 of the fore 

 wings are both wanting, leaving cubitus only two-branched. 



The Two-colored Footman, Lithosia bicolor (Li-tho^si-a 

 bi'co-lor). — This is larger than the preceding species, expand- 

 ing from one to one and one half inches. It is slate-colored, 

 with the palpi, the prothorax, the costa of the fore wdngs, 

 and the tip of the abdomen yellow. Vein V2 of the fore 

 wings is wanting, leaving cubitus apparently three-branched 



The Striped Footman, Hypoprepia niiniata (Hy-po-pre' 

 pi-a min-i-a^ta). — This beautiful moth is of a deep scarlet 

 color, with three broad lead-colored stripes on the front wings. 

 Two of the stripes extend the entire length of the wings ; 

 while the third is between these 

 and extends from the end of the 

 discal cell to the outer margin 

 (Fig. 397). The outer half of the 

 hind wings is also slate-colored. 



Vein V2 of the fore wings is preS- 'Pig. zqj.-Hypo^^re^ia ^nhnata. 



ent ; but vein V^ of the hind wings is wanting. The larva 

 feeds upon lichens, and may be found under loose stones or 

 on the trunks of trees. It is dusky, and thinly covered 

 with stiff, sharp, and barbed black bristles, which grow 

 singly from small warts. The cocoon is thin and silky. 



The Painted Footman, Hypoprepia fucosa (Hy-po-pre'pi-a 

 fu-co'sa). — This species is very similar to the preceding and 

 has been confounded with it. With the Painted Footman 

 the ground-color of the fore wings is partly yellow and 

 partly red. 



The Clothed-in-white Footman, Clemensia albata (Cle- 

 men^si-a al-ba'ta). — The specific name of this insect is some- 

 what misleading ; for although the general color of the moth 

 is white, there are so many ashen and gray scales, and dark 

 spots, that the general effect is gray. On the front wings 

 the more prominent black spots are six or seven on the 

 costa, one on the discal vein, and a row of small ones on the
