Mr, T. V. Wollaston on Microxylobius Westwoodii. 118 



Microxyloh ius Westicoodii. 



M. angusto-elongatus, ovato-cylindricus, obscure subnigro-scneus 

 (et etiam obsoletissime subvirescens), alutaceus, suboi^acus, calvus ; 

 capite rostroque minute et leviter scd argute punctulatis, hoc bre- 

 viusculo sed lineari et supra subgibboso ; prothoraee angusto, cy- 

 lindrico-subovato, punctulis miuutissimis parce et leviter irrorato ; 

 elytris subcyliudricis sed pone medium paulo latioribus, confuse 

 transversim rugatis (fere quasi subrimosis) sed baud sculpturatis 

 (i. e. vix striatis et vix punctatis), sutura antice subcarinatis ; an- 

 tennis pedibusque piceo-nigris, illis basi rufo-ferrugineis.

Obs. Species inter reliquas distinctissima ; differt corpora angus- 

 tiore et multo magis cylindrico, ubique alutaceo, subopaco, calvo, 

 prothoraee minutissime tantum parceque punctulato, elytris trans- 

 versim substriguloso-rugatis sed longitudinaliter vix sculpturatis, 

 sutura antice acutiusculo, subcariniformi. 



Judging from the type before me, this little Microocylohius 

 is as small as even the M. vestiiiis, being only a line and a 

 quarter in length. It is, however, relatively narrower and 

 much more cylindrical than that species (indeed more so than 

 any of the Microxyhbii which have hitherto been detected) ; 

 and it is likewise darker in hue, and perfectly free from even 

 a trace of pubescence. Its rostrum is a little wider than that 

 of the M. vestifus, and its tibiae are rather more curved, and 

 the punctation of its head and protliorax (the latter of which 

 is comparatively unexpanded behind the middle) is even 

 more delicate still ; and it is further remarkable for its elytra 

 (which have their suture slightly raised, or somewhat keel- 

 shaped, in front) being transversely marked with remote, 

 obscure scratches, or irregular strigffi, but almost devoid of 

 longitudinal sculpture ; and its entire surface is coarsely 

 alutaceous, and therefore but very faintly shining. 



Before closing this short paper, I may just state that Mr. 

 G. R. Crotch informs me that he possesses two examples of 

 the Cydonia vicina, Muls. (a Coccinellid which is widely 

 spread over the African continent, and which we captured 

 abundantly in the Cape- Verde archipelago), from St. Helena, 

 received by him in company with the C. lunafa, which is so 

 universal in the island. This, therefore, will add one more 

 species to the St.-Helena catalogue, augmenting the entire
