478 Mr. W. Warren on new Genera of 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 ( Salbia lauralis , 
Guen.) and Nothomastix chromalis [ Botys chromalis , Wlk.), 
with which it otherwise agrees, by the simple male antennae 
and untufted legs. 
Type P. amyntusalis ) Wlk. [Botys). 
Orphanostigma. 
Intermediate between Hedylepta ) Led., and Chnaura and 
AEthaloessa of the same author. Distinguished from Hedy - 
lepta by the absence of the long thoracic tegulae 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 Hedylepta shows a distinct orbicular stigma, 
which is entirely wanting in Orphanostigma. 
Type 0 . abruptalis , 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. moninalis , Wlk [Asopia). 
Opisthedeicta. 
This genus is akin to the first division (A) of Snellen’s 
Oligostigma , cf. Tijd. v. Ent. xix. 1876, p. 189, for which I 
have proposed the generic term Microdr aeon. Opisthedeicta , 
however, is characterized by a peculiar formation in the hind 
wings of the male. The intraneural space 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 
antennae it agrees with Microdracon. 
Type Op. poritialisy Wlk. ( Oligostigma ).
