LEPIDOPTERA 



767 



Only two species are listed from the United States, one from Texas 

 and one from the East; and these may be merely varieties of one 

 species. 



The snout butterfly, Hypatus hachmanni. — The wings are blackish 

 brown above, marked with orange*and white spots. This species 

 occurs throughout the Eastern United States, excepting the northern 

 part of New England and the southern part of Florida. The larva 

 feeds on hackberry, and in the West where hackberry does not occur, 

 it feeds on wolfberry.

The Metal-marks 



i?4+5 



The metal-marks are small butterflies, which bear some resem- 

 blance to the gossamer winged butterflies. They are distinguished 

 from the gossamer-winged but- 

 terflies by the presence of a 

 humeral vein in the hind wings, 

 and from them and all other 

 butterflies by the fact that the 

 costa of the hind wings is thick- 

 ened out to the htuneral angle 

 (Fig. 978). The fore legs are re- 

 duced and brushlike in the males, 

 normal in females. 



Only twelve species have been 

 found in our fauna, and nearly all 

 of these are from the Far West or 

 Southwest. The two following 

 species occur in the East. 



The small metal-mark, Cal- 

 ephelis virginiensis. — The upper 

 surface of the wings is rust- 

 colored, and is crossed by four or 

 five more or less sinuous blackish 

 lines on the basal two-thirds, and 

 on the outer third by two lines of 

 shining scales, that look like cut 

 steel, and an intermediate row of 

 black spots. The under surface 

 is of a brighter rust color and 

 marked as above. The expanse of 

 the wings is 20 mm. This species 

 occurs in the Southern States.

The large metal-mark, Calephelis horedlis. — The upper surface of 

 the wings is dull brownish yellow, crossed by obscure transverse 

 stripes; on the outer half of the wings are two lead-colored lines, with 

 a row of black dots between them. The under surface is of a rather
