The larva is hirsute and 



of great beauty, discovered by Mr. Sanborn at Berlin Falls, 

 N. H., August 10th, and also at Ausable Chasm, N. Y. It is 

 pure milk white, with a slight slate-colored tinge on the hind 

 wings, and is slate-colored beneath, especially on the fore 

 wings, and white on the inner edge of the hind wings. Just 

 behhid the middle of the white abdomen are tufts of tawny 

 hairs, and the tip is white. It ex- 

 pands one and a quarter inches. 



Cmmbklia has still narrower 

 wings. C. pallida Pack, is of an 

 uniform drab color and would be 

 easily mistaken for a Crambus. 

 Nudaria has broad wings like a 

 geometrid moth, with hyaline spots, 

 makes a thin cocoon of interwoven hairs. N. mundana is a 

 European moth. It is represented in this country by Eupha- 

 nessa mendica Walk., which has broader wings and longer 

 palpi. The wings have two rows of smoky transparent spots. 

 Hijpoprep)ia has rather broader wings than Lithosia. H. fu- 

 cosa Hiibner is deep scarlet, with thi-ee leaden stripes on the 

 fore wings, the middle stripe situated at the apex of the wing. 

 The larva, Mr. Saunders informs me, is "spiny and black, 

 sprinkled lightly with yellow dots and short lines ; there is a 

 dorsal row of yellow dots from the fifth to the twelfth segments. 

 The head is black." Early in May, according to Harris, it 



makes its cocoon, which is thin 

 and silky, and the moth appears 

 twenty days afterwards. 



Crocota is red, or yellowish red, 

 throughout, yvith. black margins 

 and dots on the wings. The an- 

 Fig. -21.-,. tennffi are filiform and the wings 



are broad, being triangular in form. Our most common 

 species is Crocota ferruginosa Walk., which is pale rust-red, 

 with two dusky broad bands on the outer half of the wing. A 

 much larger form is Utetheisa hella Linn. (Fig. 215), a beautiful 

 moth, whose yellow fore wings are crossed by bands of white, 

 encircling black dots, while its scarlet hind wings are edged 

 irregularly with black.
