88 APION LETHALE. 



nico ; elytris sub-cylindricis , seriatim pimctatis , punctis 

 oblongo-quadratis , approxiraatis , apice rotimdatis. — Long. 

 4 lin. 



Blackish, sparingly covered with whitish hairs , some 

 closely set forming irregular spots on the prothorax and 

 elytra ; rostrum shorter than the prothorax , stoutish , scro- 

 bes commencing a little before the middle; eyes elongate 

 narrow ; antenna? short ; prothorax conical , about as long 

 as broad , the sides very slightly rounded , irregularly punct- 

 ured , ocular lobes ciliated ; elytra at the base broader than 

 the prothorax , very gradually narrowed towards the roun- 

 ded apex , seriate-punctate , the punctures oblong quadrate 

 and approximate; body beneath with a rather dense grey- 

 ish pubescence; second abdominal segment as long or 

 longer than the two next together ; legs short. 



There does not seem to be any valid difference be- 

 tween Lixus and Cleonus'^ the slighter contour of the 

 former and the scrobes commencing more or less remo- 

 tely from the apex of the rostrum — characters by no 

 means, however, without exceptions — are perhaps as 

 good as any. The above species (which I have the 

 pleasure of naming after Mr. C. Ritsema Cz.) is not 

 unlike the Australian L. Mastersii, but is narrower, 

 the rostrum not so stout, and is spotted above, the 

 spots, however, in numerous specimens before me , vary 

 to a certain extent , some assuming an irregular interrup- 

 ted band-like form behind the middle of the elytra bei^ig 

 apparently the most constant. This species with very 

 slight variations was found by Mr. Wallace in Kaioa , 

 Batchian , Makiau , Sula and Timor.
