Genus HIMANTOPTERUS. 



Himantopterus, Westmael, Bull. Acad. Brux. iii, p. 162 (1836). 

 Thyrnara, Doubleday, Zoologist, i, p. 197 (1843). 



Type, H. fuscinervis, Westm., from Java. 

 Mange. Africa ; Assam ; S. India ; Burma ; Java. 

 The antennse bipectinated in the male, serrated in the female. 

 Mid and hind tibiae with minute terminal pairs of spurs. Frenu- 

 lum absent. Wings covered with hair-like scales ; the neuration 

 varies so much that a genus might be made 

 for each species ; the hind wing narrow 

 and terminating in a long tail, in the 

 females of some of the species filiform 

 throughout. The neuration of hind wing 

 much aborted ; the costal and internal 

 veins, when present, anastomose for some 

 distance with the subcostal and median, 

 which meet toward the end of the broad 

 part of the wing to form the cell. 

 They are degraded forms which have 

 Fig ' ^Jaida H f mt ^ term arisen from an ancestral type ; the veinlet 

 in the cell and vein 1 c of fore wing being 

 more or less developed, show that they belong to the Zygcenidce, 

 and the absence of mouthparts places them in the subfamily 

 Phaudince near Pryeria, while on the other hand they are allied to 

 the Psyc7iid.ee. 



613. Himantopterus dohertyi, Elwes, Trans. Ent. Soc. 1890, p. 332, 



pi. x, figs. 1-7. 



S . Fuscous ; the collar and end of abdomen orange. Fore wing 

 with the disk diaphanous ; veins 4 and 5 from the lower angle of 

 the cell, 10 and 11 absent. Hind wing with the basal part orange, 

 the distal portion and tail black, with a few yellowish hairs at tip ; 

 neuration less aborted than the other members of the genus, 8 

 veins being present. 



$ . The thorax ochreous : the whole of fore wing diaphanous ; 

 hind wing filiform throughout, but with the neuration as in male.

Differs from dohertyi in the disk of the fore wing being red- 

 dish ; veins 4 and 5 stalked and 10 present. Hind wing broader 

 and orange, with a round black spot below the costa and another 

 near the anal angle ; the tail black ; veins 1 and 3 absent.
