The species are rare, and Ihe genera may be readily recognized l>y the sin- 

 gularity of their forms. 



Synopsis of (he Genera. 



Wings very oblong, aDgulnr; hind wings cut ire Goniacidalia. 



Costa of fore wings very convex; outer e go deeply excavated ; hind wings tridentate... Callcdaptcryx. 

 Core wings entire ; apex mucb ronnded; bind wings tridentate Callizzia.

Goniacidalia Pack., Fiftb Hep. Peab. Acad. Sc.GS, 1-7:!. 



Head and legs as in Acidalia, the antenna' in the male slightly ciliated; in 



the female simple. Palpi very short, as in Acidalia. This singular genus may at 

 once lie recognized by the oblong primaries, 1 he apex being prolonged, while the 

 inner tingle is elongated into a blunt, rounded, allotted tail, making the wing 

 as broad near the base as near the apex, and beyond the "tail*' the inner edge 

 is exactly parallel to the costal. The outer edge is short and straight, less 

 oblique than in the narrow-winged species of Acidalia. The hind winys are 

 still more grotesque than the primaries, appearing as if crumpled up from not 

 having properly expanded alter the moth had left the pupa. They are so 

 deeply notched in the inner part of the outer ^{]\ie of the wing as to appear 

 bifurcate, sending the inner fork, which is acute, nearly as far as the tip of 

 the abdomen, while the outer half of the wing forms the other fork. The 

 inner edge of the wing is much revolute, and near the base of the inner fork 

 carries a crest of tine inrolled hairs. The venation is very remarkable. 

 There is a subcostal cell and but three subcostal veins, the main vein branch- 

 ing but three times; the usual two subapical veins wanting. The independ- 

 ent vein is thrown off" from the base of the anterior discal veins. The third 

 median vein is very short, and its origin is very remote from the first two.

2 $ and 1 9. — Brick-red; head with front and palpi red; vertex and 

 antennas dull yellowish. Fore wings reddish, with a broad, median, yellowish 

 patch, not reaching to the inner edge, and extending to the base of wing, inter- 

 rupted by a basal reddish line; costa reddish as far as the middle of the wing. 

 This yellowish area is centered with the reddish-brown discal dot. Outer 

 margin of the wing paler, with a submarginal, yellowish, zigzag line, not reach- 

 ing any farther than the basal yellowish patch. Hind wings pale reddish; rev-
