Head small, but free from thorax, tongue nearly as long 

 as body; antennae prominently hooked at tips. Forewings 

 excavate below apex and above anal angle ; hindwings with 

 the margins slightly dentate. This genus approaches in some 

 points the tropical genus Perigonia.

 by a dark brown oblique band, beyond which is a line fol- 

 lowed by shade spots of same color; hindwings dark brown 

 with an oblique reddish central band, with pale yellow 

 fringes broken with brown; beneath rusty red with pale 

 yellow lateral stripe beneath the wings running from the 

 antennae. Can. southward. Very common. May to Aug. 

 Lan-a, green or brown, on Ampdopsis and grape and has a 

 caudal horn wanting in the mature larva of the next genus. 



Tliyreus. Swains.

 fusiform antennae which terminate in a long hook; thorax 

 somewhat globular, stout, tufted behind; abdomen flattened, 

 with anal tufts pointed in the female, more spreading in

 it sufficiently resembles the preceding. The abdomen in shape 

 recalls the highest genera of the group. 



Abbotii. Swains. Forewings very dark brown, an- 

 gulated on outer margin, crossed by several darker dentate 

 lines. Head wings lemon yellow with dark brown terminal 

 band ; beneath lighter colored. Lan-a greenish or brown,

 Antpelopsis and grape. The moth is locally quite common.
