Dr. hviELiv^sObfervatkus on the Genus Paufus. 247 



Both thefe fpecies I have carefully compared, and found to 

 agree in many circumftances; but I ilia 11 here only mention the 

 mod finking ones, as well as thofc which Hand in need of fame 

 explanation, or where, from want of proper termini iechnki, I fliali 

 be under the neceffity of ufing circumlocution in order to be under- 

 ftcod. 



The Body is hairlefs, fmooth, and poliftied, above fomewhat de- 

 prefled, before narrower, and behind nearly cylindrical ; the fiu 

 fmall, being from the top of the antennae to the end of the abdo- 

 men only three lines long, and acrofs the elytra not quite one broad ; 

 the colour uniform, a darker or lighter brown ; the motion fteady and 

 flow, at leaft in the fpecies I have feen alive, ft is very unlike all 

 other genera I know ; but it feems to come neareft; to the Clerus of 

 Fabricius, bearing to it, at leaft upon the whole, fo much natural 

 refemblance that its moil proper place in the fyftematical arrange- 

 ment will be next after that genus. 



The Head is fmaller and fhortcr than the thorax, almoft round 

 and at the bafe furrounded as it were by an annular fegment ; in the 

 living animal it is pointing flraight forward, but when dead it com- 

 monly bends a little downwards. The clypeus is minute, and more 

 or lefs deprefled in the middle. On the throat there is a convex 

 fpot, raifed in form of a triangle, which is nearly equilateral, the 

 bafe of which forms a crofs-bar between the eyes, its two upper 

 angles being acute, but the lowermoft cut off by the annular feg- 

 ment juft mentioned. 



The Eyes are rather large, tranfverfally oblong, prominent, and 

 fituated in a focket, the brim of which is elongated into one angle 

 beforelying horizontally, and another behind Handing upright; 

 which ftru&ure feems to prevent the infe6t from being able to look 

 in any other direction than forwards.
