254 Mr. G. R. Waterhouse on some new Coleoptera. 



as it were sprinkled on the elytra. The antennae have a slight 

 pitchy hue, and so have the tibiae ; the femora are red, but blackish 

 at the extremity. 



The specimen from which this description is taken is a female, and 

 has the terminal segment of the abdomen conical and covered with 

 rugae. The insect, which I suspect to be the male, differs in having 

 the elytra narrower and rounded at the extremity, the rostrum rather 

 coarsely punctured, and has three oblong furrows at the base. 



Apocyrtus adspersus. 



Ap. ater ; squamis viridibus adspersis ; tibiis antennisque piceo-nigris, fe- 

 moribus rufescentibus ; rostro rugoso, ad basin distincte transversim im- 

 presso, foveis tribus oblongis impresso ; capite inter oculos punctata atque 

 linea longitudinali impresso ; thorace subgloboso, antice posticeque trun- 

 cate-, tuberculis nitidis crebre obsito. Elytris thorace paulo latioribus, 

 rugosis et tuberculis minutis crebris. Long, corp. 3 lin. 



The form of this insect is very nearly the same as in Apocyrtus pro- 

 fanus, Eschsch., but the elytra are rather shorter in proportion. The 

 rostrum is rugose, punctured, has a very distinct transverse impression 

 at the base, a broadish and shallow longitudinal groove in the mid- 

 dle, extending from the base and terminating nearly in a line with 

 the antennae, and on each side of this is a similar groove. The head, 

 between the eyes, is distinctly punctured, and has a longitudinally im- 

 pressed line ; the eyes are round and but little convex. The thorax 

 is nearly globose, but truncated before and behind ; its surface is 

 thickly studded with glossy tubercles. The elytra are about hajf as 

 long again as the thorax ; they are truncated in front, increase in 

 width in the middle, where they attain a diameter very slightly ex- 

 ceeding that of the thorax, and at the apex they are somewhat acu- 

 minated, but rounded at the point ; their surface is subsulcated, very 

 rough, having coarse confluent punctures and small pointed tubercles. 

 Numerous round bright green scales are scattered on the thorax and 

 elytra, and there are a few on the head between the eyes. The tibiae 

 and antennae are pitchy, and the thighs are of an obscure red colour, 

 excepting at the apex, where they are dusky. 



This is a small species about equal in size to Phyllobius argentatus, 

 and less than the Ap. bispinosus ; the female is readily distinguished 

 from the corresponding sex of the insect last mentioned by the want 

 of the spines at the apex of the elytra ; the thorax is smaller in pro- 

 portion. The male differs from the supposed male of Ap. bispinosus in 

 having the rostrum more coarsely sculptured, and in the longitudinal 

 groove in front of the eye being distinctly joined with the antennal 

 groove ; this groove is represented in $ bispinosus by an oblong fovea 

 which does not run into the antennal groove ; the thorax is smaller 

 in proportion to the elytra. 



Apocyrtus pulverulentus . 



Ap. niger, squamis viridibus minutissimis dense pnlvcrulentis ; pedibus 

 rufo-testaceis, vel pieeo-testaceis, pilis minutis a'.bis veslitis; anter.nis 

 piceis ; rostro rugoso, canaliculato ; thorace subgloboso, tuberculis nitidis
