204 Mr. D. Sharp on some 



is said to have an excessively wide distribution, but I am 

 not myself able either to confirm or to limit this opinion. 



I Avill make still one other remark about these Hawaiian 

 individuals, namely, that when the intermediate coxal 

 cavities are looked at from behind they are seen to possess 

 a distinct outward transverse prolongation, although 

 Lacordaire states that they are closed externally. 



I have not any information as to the distribution of this 

 species in the various islands of the group, but I believe 

 all my four specimens are from Oahu. 



AsTRiMUS (new name). 



Asfrhmis ohscurus, n. sp. Fusco-niger, griseo-pubescens 

 et setosus, opacus ; prothorace subdepresso, disco in- 

 Eequali, sed vix discrete bi-impresso, opaco, tomentoso, et 

 setoso, lateribus in medio ]irominulis sed haiid tuberculatis, 

 basi constricto ; elytris thorace paulo latioribus, fortitcr 

 punctatis, punctis versus apicem minoribus, angulo suturali 

 acute prominulo. Long. 11^ mm., lat. 3 mm. 



This species has much the appearance of the Stromatium 

 group ; its sculpture and colour are much obscured by the 

 })ubescence and setfe. The elytra are slightly broader 

 than the greatest width of the thorax ; this latter has an 

 indistinct tubercule in the middle, some distance in front 

 of the hind margin, and near this obscure elevation the 

 surface is more depressed and densely pubescent ; on. the 

 outside of this depression the surface is very obscurely 

 elevated. The middle coxal cavity is not really closed, 

 although it is very nearly so. The projecting point of the 

 side of the metasteruum, which helps to close the cavity, is 

 not shining, neither is it turned out from the ]ilane of the 

 rest of the metasternum, and, therefore, it is but little 

 conspicuous. 



Mr. Blackburn has sent me a single individual as 

 No. 87 ; it is, I believe, a male. 



I think it probable that Fairmaire's Tahitian Stromatium 

 hirtum will prove closely allied to this insect. I give 

 below its structural characters. 



Form rather depressed, surface pubescent. Head with 

 the front very short, mandibles short, conspicxiously hairy 

 externally ; eyes coarsely facetted, largely and deeply 

 emarginatc, their lower lobe not approaching so near to the 

 mesial (longitudinal) line as the upper one does ; antcnnal 

 tubercles distaictly elevated, and with a quite distinct
