island. It is very imicli smaller than the last species, but 

 rather larger than either of those which Inlhnv ; and it may- 

 be further reeoiiiiized bv its black, shining, and eom])aratively 

 un])ubescent surface, by its strongly and closely punctured 

 head and prothorax (the subbasal line of which is raised, as 

 in the two following s])ecies, and hardly at all curved), and by 

 the convex interstices, deep crcnate strite, and numerous bright 

 red j)atches of its nearly glabrous elytra.

This species appears to be a little more ovate, and perhaps 

 also (on the average) a trifle smaller, than the X. rufojyi'ctus • 

 and it is abundantly distinguished by its greenish-brassy, 

 shining, and coarsely but sparingly pubescent surface, by its 

 greatly elevated and evidently curved subbasal prothoracic 

 line, and by the sti'ise and largely developed punctures be- 

 coming evanescent on the posterior half of its elytra. One of 

 the two specimens now before me (and which were taken in 

 St. Helena by Mr. Melliss) seems to be immature ; for it is 

 altogether paler (indeed well-nigh ajneo-ferniginous) , and 

 there are indications on its elytra of an obscure, central, den- 

 tate, blackish fascia, which the darker surface of the other 

 example appears to render quite untraceable. 



56. Notioxenus alutaceuSy n. sp. 



N. viridi-seneus, subnitidus, alutaceus (sed hand punctatus), pube 

 demissa fulvescente parce vestitus ; prothoracis linea subbasali 

 subcurvata elevata ; elytris posticc niagis abbreviatis, striis (sutu- 

 rali profunda basi evanescente cxcepta) obsoletis ; antennis piceis, 

 basi rufo-testaceis ; pedibus piocsecntibus, tibiis (tarsisqne ad 

 basin minus evidenter) dilute rufo-testaceis.
