162 RAWASIA DIARDI. 



pecially before the basal margin) flattened in ilie middle, 

 the punctuation fine and dispersed. The yellowish-grey 

 pubescence is here and there of a paler colour , and on the 

 anterior half a paler median line and four paler dots may 

 be observed. The scutellum is very small , hardly visible. 



The elytra are proportionally shorter and broader than 

 in the allied species , the shoulders better visible and roun- 

 ded. The elytra are provided with rows of punctures. The 

 interstices are equal in width and not raised ') , those be- 

 tween the alternate striae (commencing with the interstice 

 between the suture and the first row of punctures) are 

 decorated with black and pale yellow spots. The black 

 spots are less elongate than in the allied species and the 

 elytra have no transverse baud of paler hairs behind the 

 middle. 



Under surface not very densely clothed with yellowish- 

 grey hairs, and provided with shallow and rather disper- 

 sed punctures. The legs are similar to those of the allied 

 species. The black ring at the apex of the tibiae is nar- 

 rower at the under surface and is absent on the forelegs. 



Hab. Buitenzorg, West-Java (Diard). Type specimen in 

 the Leyden Museum. 



Although I have only a single specimen ((ƒ) at my 

 disposal , 1 have nevertheless described the insect , because 

 it belongs to a remarkable genus , which was unknown 

 up to the time that I described the Sumatran species. 

 Other species will probably be discovered by further in- 

 vestigations.

1) In Rawasia Bitscmae Koel. the interstices are alternately narrower ami 

 appear to be slightly convex. The narrower interstices commence with that 

 which is situated between the suture anil the lirst row of punctures and this 

 is the narrowest of all. — In Rawasia DiarUl Iloel on the contrary tliis 

 interstice is decidedly of the same width as all the others. The blackish brown 

 spots being less elongate , the colour of the upper surface of the insect appears 

 somewhat paler. '
