106 Mr. F. P. Pascoe on some new or little-known 



as is really the case, that is to say, with the addition of the basal 

 one. A. Fryi and A. incensa were both taken by Mr. Fry at Rio. 



Acropis incensa. 



A. rufo-picea, fulvescenti-hirta ; elytris subseriatim tuberculatis, tuber- 

 culis setiferis, fasciculis plmimis fuscis in medio obsitis ; pedibus fer- 

 rugineis. 



Hub. Brazil (Rio). 



Differs from the last in its much smaller size, comparatively narrower 

 and longer elytra, in the more numerous tubercles, and brown fascicles 

 of hairs, the almost unvarying hue of the pubescence, although near 

 the shoulder and apex may be traced rather more densely set patches 

 of hairs than elsewhere, and the more uniform colour of the legs. 

 Length If line. 



Acropis aspera. (PI. VI. fig. 1.) 



A. nigra; prothorace granulato; elytris seriatim tuberculatis, setiferis, 

 macula alba pone humeros, postice fasciculo nigro indutis ; tibiis tarsis- 

 que ferrugineis. 



Hub. Brazil (Para). 



Black, very slightly shining, and nearly free from pubescence, except 

 two small patches on the anterior margin of the prothorax, and a short 

 oblique white stripe, which, however, may be resolved into three spots, 

 below the shoulder ; scutellum rounded behind, naked ; prothorax 

 covered with small flat granulations ; elytra with a large fascicle of 

 black hairs on the lower third of each, the tubercles varying in size, but 

 all furnished with a rigid black seta ; antenna?, tibiae, and tarsi ferru- 

 ginous. Length 2 lines. 



Lemmis [Colydiidae], 



Head vertical, rounded in front, and prolonged at the sides into two 

 short peduncles bearing the eyes. Antennae short, eleven -join ted, the . 

 last two forming a short ovate club. Prothorax short, very transverse, 

 narrower behind, broader than the head anteriorly, the sides strongly 

 denticulate. Elytra nearly regular above, not broader, except at the 

 base, than the prothorax. Legs slender, first tarsal joint scarcely 

 longer than the second. 



The other characters of this genus are the same as those of Acropis, 

 to which, indeed, it is nearly allied ; the form, however, of the pro- 

 thorax, added to the apparent absence of asperities, and the peculiar 

 scaly crust, which covers the whole of the upper surface, as if a layer 

 of opake varnish had been applied to it, obviously prevent its union 

 with that genus. The shortness of the first tarsal joint, being more 

 of a comparative character, is, perhaps, of less importance.
