406 Mr. T. V. Wollaston on the Coleoptera of St. Helena. 



nigh be supposed to form the type of a different genus from 

 its allies ; but its elevated prothoracic line and the other de- 

 tails of its structure show it to be a true Notioxenus. 



Compared with the four species which have already been 

 defined, the present one may immediately be known by its 

 narrower and more oblong outline and pale ferruginous hue, 

 the elytra only being obscurely decorated with a darker su- 

 ture and a more or less interrupted and anteriorly evanescent 

 discal line, both of which are sometimes barely traceable and 

 at others conspicuous. Indeed the outer lateral margin is 

 likewise often blackened ; and there are frequently indications 

 of one or two small cloudy dashes placed longitudinally (as 

 though formed by an evanescent broken-up line) on either 

 side of the interrupted discal band. Its antenna are rather 

 short, and its legs somewhat incrassated ; and its entire sur- 

 face is opaque and densely clothed with a coarse, decumbent, 

 cinereous pubescence. Its head and prothorax are roughened, 

 and its elytra are deeply punctate-striate, the striaa extending 

 from the base to the apex.

A single and rather imperfect specimen of a small Homoeo- 

 dera^ which was taken at St. Helena by Mr. Melliss, is so very 

 remarkable in its nearly opaque, coriaceous surface, and its 

 total freedom from sculpture, that I have no hesitation, even 

 from such scanty material, in describing it as new. The ex- 

 ample before me is manifestly a rubbed one, and is conse- 

 quently almost black (there being merely a slight cyaneous 

 tinge on the elytra) ; but a few coarse, whitish, decumbent 

 scales would seem to indicate that the species is normally 

 more or less clothed. Its antennae and legs appear to be dark, 

 the former (of which the club is perhaps somewhat more com- 

 pact than is usually the case in the allied members of the 

 group) having merely the basal joints rufo-ferruginous.
