Hab. — Malay Peninsula ; Singapore (Wallace — coll. Feld.). 



Felder does not give the exact dimensions of this species, but refers it in general terms to 

 the size of two other members of the genus. From this we may infer that it is somewhat of 

 the size of Gertfdus stjmethus. 



Genus NEOPITHECOPS, gen. nov. 



Pithetop*, Moore (nec HorsfieM), Lep. Ceyl. i. p. 72 (1881 1. 



^Vmgs broad. Anterior wings witb the costal margin arched and convex, outer margin convex, inner 

 margin slightly sinuate. Costal nervure not extending to centre of costal margin ; first, second, and third 

 subcostal nervuleei emitted at about equal distunec from each other before end of cell, first before middle of 

 cell, third and fourth bifurcating beyond centre of third, the fourth not reaching apex of wing ; cell long and 

 broad ; lower median nervulc emitted about centre of median nervure. Posterior wings ovate ; the posterior 

 margin strongly convex. Costal nervure arched and extending to apex of wing; subcostal nervules bifurcating 

 before apex of cell. Body moderately slender. Palpi porreet, the second joint stout and compressed ; 

 apical joint slender, longest in the female; legs moderately long and slender, basal joint of the tarsi much 

 elongated. Antennai with a well-formed, prominent, and spatulate apical club. 



This genus is quite distinct from i'ithecops (of which the type is the Javan species 

 P. hylax), although similarity in colouring and markings has led to considorahle confusion. 

 In I'ithccops the first subcostal norvuh' distinctly and strongly anastomosed with the costal 

 nervure, in Xeopithecops that nervule is quite free and situate some clear distance from the 

 costal nervure. 



The geographical range of Neopitlmaps (of which I take the type to be the Ceylonese 

 species N. dlutrma, Moore) is at present unknown, and till all the species (many undescribed) 

 which really belong to it are accurately determined little can he stated on that point. It is, 

 however, known from Ceylon, I possess an undescribed species from the Andaman Islands, and 

 it is probably distributed more or less throughout the Malayan Archipelago.
