94 Mr. F. P. Pascoe's Descriptions of New Genera 



appearance ; under surface, legs and antennae testaceous brown, 

 with a sparse silky pubescence. 

 Length 8 lines. 



Zatrephus. 



Head moderate ; antennae distant, shorter than the body, the 

 first four or five joints rounded, the rest dilated on one side ; 

 palpi short, nearly equal, the last joint nearly as long as the 

 rest together ; thorax longer than broad, narrow in front and 

 corrugated ; elytra rather broad, truncate at the apex ; legs 

 short. 



The two insects which I have placed in this genus differ in 

 habit, so that their being congeneric is doubtful. In all proba- 

 bility these with Culpnzia and Xoanodera, and possibly other 

 groups, are the representatives of extensive series, for of the five 

 species composing these three genera, Mr. Wallace has detected 

 only six specimens, Xoanodera Ir'igona alone having occurred a 

 second time ; tJieir capture, then, is a mere accident, and it may 

 be left to the imagination to infer how many more await future 

 research. 



Zalepkiis pannosus. (PI. XXIII. fig. 3.) 



Z. biunneus ; prothorace riigoso fulvo-lanuginoso ; elytris 

 elongatis, pilis fuh o-albidis densissime tectis. Borneo. 



Brown ; liead with a deep groove between the eyes; prothorax 

 very rough, with indeterminate striae and tubercles, and here and 

 there with little patches of fulvous woolly hairs ; elytra densely 

 covered with pale brownish white appressed hairs, except a naked 

 glossy spot near the apex of each ; antenna? everywhere covered 

 with short fulvous hairs ; legs and under surface with pale brown 

 hairs. 



Length 14 lines. 



Zalrephus inscilux. 



Z. fuscus ; prothorace medio bicostato, lateribus corrugatis ; 

 elytris brevibus, sub-sericeis flavis, postice dilatis. Borneo. 



Head and thorax deep brown, the latter at both the anterior 

 and posterior margins with two transverse striae, between which 

 are two central longitudiiial libs, the sides being irregularly cor- 

 rugated ; elytra wider posteriorly, the apex divaricae, pale brown, 

 covered with short yellowish silky hairs ; under surface, legs and 

 antennae clothed with short hairs.
