LEPIDOPTERA 705 



present; but Vein M2 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. — This species is very 

 similar to the preceding one and has been confounded with it. With 

 the painted footman the ground-color of the fore wings is partly 

 yellow and partly pink. 



The clothed-in-white footman, Clemensia albdta. — The specific 

 name of this insect is somewhat 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 outer margin. The 

 hind wings are white, but finely dusted with gray scales. With this 

 species Vein M2 is present in both fore and hind wings. 



The banded footman, Illtce unijascidta. — This little beauty (Fig. 

 896) occurs in the Atlantic States from New York to Texas. The fore 

 wings are lead-colored, and crossed by a yellow band, 

 which extends also along the inner margin to the 

 base of the wings. The hind wings are pink except 

 the apex, which is lead-colored. There is much varia- 

 tion in the width of the yellow band. Fig. 8g6.—Illice 



There are several closely allied species which are unifasciata. 

 difficult to distinguish from this one. 



The pale footman, Cramhidia pallida. — This moth is of a uniform 

 drab color with the abdomen and the inner, part of the hind wings 

 paler; it expands 22 mm. The moths of the genus Cramhidia can be 

 recognized by the fact that veins M2 and M3 of the fore wings are 

 both wanting, leaving cubitus only two-branched. 



The two-colored footman, Tigrioides htcolor. — This is larger than 

 the preceding species, expanding from 2 5 to 3 7 mm. It is slate-colored , 

 with the palpi, the prothorax, the costa of the fore wings and the tip 

 of the abdomen yellow. Vein M2 of the fore wings is wanting, leaving 

 cubitus apparently three-branched. 



Subfamily NOLIN^ 



The Nolinse are small arctiids in which the ocelli are wanting and 

 in which there are tufts of raised scales on the fore wings. It is a small 

 subfamily including only fifteen North American species. Our most 

 common species is the following. 



Celania triquetrdna. — This is a gray moth with a wing-expanse of 

 1 7 to 20 mm. On the fore wings there is a short black or dark brown 

 stripe at the base of the costa, and beyond this two spots of the 

 same color, the outer one is near the middle of the length of the costa. 

 The larva infests the foliage of apple, but not in sufficient numbers 

 to be a pest.
