RHOPALOCERA MALAYAN A. 209 



1. Allotinus unicolor. 



Allutinus unicolor, Folder, Eeise Nov. Lep. ii. p. 28G, u. 369 (1875). 



" 3" • Aire supra rut'esceuti-i'usc£e, anticie marginem versus obscuriores, posticas ciliis sordide albidis, 

 margine ante ea obscuriore. 



" Alae subtus glaucescenti-albfe, ciliis fusco-albis, apud venarum exitus obsolete nigro-fusco maciilatis, 

 omnes, anticre limbo interno solum excepto, fuscescenti subtiliter variegatae, serie submarginali raargini 

 parallela macularum parvularum fuscescentium, anticarum maculis quinque costalibus arrosis, macula 

 miuuta et litura transversa in ccUula, fasciola discocellulari fasciaque exteriore, maculis sex inequalibus 

 formata, posticarum maculis quatuor minutis basalibus, maculis binis cellularibus, fasciola discocellulari 

 arrosa, maculis duabus subcostalibus subbasalibus, duabus subcostalibus grossioribus in medio (sixperiore 

 magis extrorsum jacta), aliis sex posterioribus in serie margini parallela (duabus intermediis elongatis, 

 reliquis paribus, decrescentibus) septimaque parva interna cano-brunneis." 



" Abdomen cano-fuscum, ventre albido." 



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



Fekler 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 Genjdus sijinetJnis. 



Genus NEOPITHECOPS, gen. nov. 



Pithecops, Moore (nee Horsfield), Lep. Ceyl. i. p. 72 (1881). 



Wings broad. Anterior wings with 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 nervules emitted at about equal distance 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 nervule emitted about centre of median nervure. Posterior wings ovate ; the posterior 

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

 before apex of cell. Body moderately slender. Palpi porrect, 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. Autennje with a well-formed, prominent, and spatulate apical club. 



This genus is quite distinct from Pithecops (of which the type is the Javan species 

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

 In Pithecops the first subcostal nervule is distinctly and strongly anastomosed with the costal 

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

 costal nervure. 



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

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

 which really belong to it are accurately determined little can be 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.
