68 p. CAMERON, OX THE MALAY FOSSORIAL 



Mular space large, three fourths of the length of the antennal 

 scape ; the last joint narrowed but not compressed. Clypeus 

 distinctly longer than wide, clearly separated above from the 

 eyes, rounded on top ; the apex trilobate, the central lobe 

 small and clearly separated ; its sides and the sides of the 

 front are pale, more yellowish in hue and densely covered 

 with silvery pubescence. Pro- and mesothorax closely, dis- 

 tinctly rugosely punctured ; the metanotum transversely stria- 

 ted, but not closely or strongly. The tarsi ap])ear longer than 

 usual compared with the tibiœ, Antennal keel stout. Occiput 

 black in the middle. The keel bordering the base of the pro- 

 thorax is sharply raised. 



Allied to P. diaholicus Sauss. of which I only know the ^. 

 The d" has been described by Mr. 8chulz, (Beri. Ent. Zeit 

 XLIX, p. 229). Schulz's description of the malar space 

 »gleich der Länge des 3 Fuhlergeissel gliedes« and of the 

 clypeus as »ungefähr so long als breit« cannot apply to the 

 species I have described : the malar space is clearly longer 

 than the S""* funicular joint and the clypeus is distinctly 

 longer than wide. 



Polistes javanicus sp. nov. 



Dark castaneous brown, the apical half of the 8''' antennal 

 joint, more or less of the mesonotum, mesopleurœ and base 

 of abdomen, black ; the wings dark fuscous, towards the apex 

 more or less tinged with fulvous, the nervures and stigma 

 black. Front, vertex, pro- and mesothorax closely, rugosely 

 punctured, the punctures running into reticulations and stria- 

 tions ; the metanotum coarsely, transversely striated, the strife 

 finer and closer in the depressed centre ; the apex of the 

 metapleurîe closely, strongly obliquely striated ; the base with 

 shallow, clearly separated punctures, i^ and n.
