478 Mr. W. Warren on new Genera q/ Pyralidae. 



hind margin ; labial palpi stout, upcurved in front of face ; 

 male antennae shortly pubescent ; lines and margins of stig- 

 mata coarse, the former abruptly bent ; last abdominal 

 segment of female and last two of the male dark marked 

 above. 



Distinguished from Arthromastix lauralis [Salhia lauralis, 

 Guen.) and NotJiomastia: chromalis {Botys chromali's, Wlk.), 

 with which it otherwise agrees, by the simple male antennas 

 and untufted legs. 



Type P. amyntusalis^ Wlk. [Botys). 



Orphanostigma. 



Intermediate between Hedylepta, Led., and Chnaura and 

 j^tlialoessa of the same author. Distinguished from Hedy- 

 lepta by the absence of the long thoracic tegul» in the male, 

 and from the others by the shorter, rougher, and blunter 

 labial palpi. In colouring and markings it agrees more with 

 the former, but Hedyhpta shows a distinct orbicular stigma, 

 which is entirely wanting in Orphanostigma. 



Type 0. ahruptalisj Wlk. (Asopia?). 



Aplomastix. 



Allied to Stenia and Blepharomastix^ Led., but with up- 

 curved instead of porrect palpi ; from Pterygisus, Butler, with 

 which it agrees in the form of the palpi, it is distinguished by 

 having in the male thickly laminated antennae, not ciliated, but 

 simply finely pubescent beneath, and with the basal joint 

 swollen. 



Type A. nioninalis, Wlk {Asopia). 



Opisthedeicta. 



This genus is akin to the first division (A) of Snellen's 

 Oh'gosfigma, cf. Tijd. v. Ent. xix. 1876, p. 189, for which I 

 have proposed the generic term Microdracon. Opisthedeicta, 

 however, is characterized by a peculiar formation in the hind 

 wings of the male. The intraneural sj)ace between the first 

 and third median nervules, from their origin to close upon the 

 hind margin, is bare of scales above and below, and in the 

 centre of this bare patch underneath there is visible a short 

 fine black dash. In the formation of the labial palpi and 

 antennjB it agrees with Microdracon. 



Type Oj). poritialisj ^^'lk. {Oligostigmn).
