be well known (and perhaps even recorded) for some other 

 tropical country. Yet, as I have been unable to identify it 

 with any of the numerous species to which I have had access, 

 I think it better to run the risk of its having been already 

 described than to omit it altogether from the present catalogue. 

 The main features of this Bruchus seem to consist in its 

 reddish-brown hue, the elytra, however, being more pale and 

 rufescent than the head and prothorax ; in the latter being 

 dappled with cinereous scales, which are concentrated into a 

 squarish central bipartite patch in the middle (behind the 

 scutellum), and sometimes apparently into two obsolete and 

 fragmentary (or broken-up) oblique bands ; in its head being 

 powerfidly keeled ; in its elytra being deeply striate (with the 

 interstices convex), and likewise ornamented (in unrubbed 

 specimens) with rudimentary bands or fascias, on either side, 

 composed, in examples Avhich are highly coloured, of darkish 

 cloudy patches with a few ashy scales between ; in the antenna? 

 of the male being very much longer than those of the female, 

 and deeply pectinated internally ; and in its two posterior 

 femora being armed beneath with two small denticles, along- 

 side each other and arising out of the inner and outer edges 

 respectively — whilst the two inner angles of its two hinder 

 tibiae are each terminated by a spine, one of which (particu- 

 larly in the male sex) is robust and elongated.

B. fere ut species prascedens, sed paulo angustior ac sensim magis 

 ellipticus (pygidio minus perpendiculari), capite minus evidenter 

 carinato, prothorace sensim profundius punctate, elytris clarius 

 rufescentibus laetiusque pictis, multo magis tenuiter leviusque 

 subcrenulato-sti'iatis, interstitiis valde depressis (nee convexis), 

 antennis brevioribus, femoribusque posticis omnino simplicibus 

 (nee subtus denticulatis) et spinis terminalibus minus robustis.

Although with much the same colouring, and prima facie 

 aspect, as the last species, it is quite impossible to identify Avith 

 it the single example from which the above diagnosis has 

 been drawn out — though I feel it extremely likely that both 

 of them are natives of the same country (wheresoever that 

 may be), and may perhaps have become naturalized, through 

 the medium of commerce, in the stores and granaries of St. 

 Helena. The specimen before me (which was captured by 

 Mr. Melliss) appears to be a female one, so that I am unable 

 to decide whether there are any particular features (of anten- 

 nae &c.) to distinguish the opposite sex ; but, judging from 

 this individual, the species is a trifle narrower and more
