MOTHS FROM SOMALILAND. 145 



scarcely one-half cell, DC not very oblique, SC" well stalked, 

 E,'^ little before middle of discocellulars, M^ well stalked. 



Type of the genus : Hemidromodes rohusta Prout {Hiero- 

 chthonia). 



A connecting link between Hierochthonia and Syndromodes ; 

 the absence of the male, and the curious fact that the female 

 examined had no trace of median spui'S (though both legs are in 

 good condition), led me to refer the species to the former genus. 

 From Syndromodes it difiers in antenna, male hind leg, robust 

 female abdomen, etc. 



Hemidromodes robusta (Prout).

Excepting the two females marked *, all are smaller — mostly 

 considerably smaller — than the type specimens from Port Sudan. 



In this species the fringes (which in neither of the originals 

 were quite perfect) are long, proximally green, distally ochreous 

 whitish. 



Hierochthonia featheri, sp. n. (PI. II. fig. 23, 2 .) 



2 , 24-26 mm. Face green. Palpus minute, whitish. Tongue 

 vestigial. Antennal shaft white, pectinations long. Vertex 

 white; occiput green. Thorax above green, beneath white. 

 Abdomen robust, dorsally green, becoming white posteriorly 

 and ventrally. Fore wing moderately broad, SC'' from cell, 

 anastomosing with C, SC'^ from shortly after R\ anastomosing 

 with SC\ R' well stalked, R- rather extremely placed, M' shortly- 

 stalked ; uniform bright green, nearly as the genus Euchloris 

 or slightly more bluish, distal one-third of fringe white. Hind 

 wing moderately broad, costal margin ratlier long, apex rounded, 

 C anastomosing to near end of cell, R" rather extremely placed, 

 M' short-stalked ; green, rather paler than fore wing, especially 

 towards base and costal margin. Under surface pale green.

 Apr. 22,-1 2; May 9,-1 2 (type); Dec. 10,-1 2- 



Probably related to petitaria Clir., notwithstanding the broader 

 wings and strongly pectinate antenna. It is unfortunate that 

 the males in this group are still unknown.
