Anthribidae. 



Eugigas insalindiae v. d. Poll , nov. spec, (will be described 

 in the present part of this Journal). — 1 Q. 



Xenocerus saperdoides Gylh. — 1 cf . — The Anthribid figured 

 by Labram & Imhoff as Xenocerus saperdoides var. does 

 not belong to this species but is identical with X. jia- 

 gellatus F&hrs.

Pachylocerus pilosus Guer. (? = unicolor Dohrn , Stett. 

 Ent. Zeit. 1878. p. 359; — id. 1880. p. 149; — id. 

 1883. p. 158). — 1 ex. — Of this species the Leyden 

 Museum possessed already a specimen from Java: Ke- 

 manglen , Tegal Residency, captured in August (Lucassen), 

 another from Sumatra (v. d. Bossche) and two specimens, 

 apparently (ƒ and 9? fi'om Borneo (Schwaner). — Pa- 

 chylocerus crassicornis Oliv. is represented in our Museum 

 by a single specimen from the old collection of Calkoen's. 

 Pachylocerus plumiferus Pascoe, and perhaps also P. 

 corallinus Hope , may, I think , prove to be mere varie- 

 ties of this species. 



*Rhytidodera simulans White. — 1 ex. 



'*Gnatholea subnuda Lacord. — 2 cf and 1 Q.
