Genera and Species of Coleoptera. 107 



Lemmis ccelatus. (PI. VIII. fig. 3.) 



L. oblongus, grisescens, setis hamatis brevissimis obsitus ; antennis capite 

 brevioribus. 



Hub. Brazil (Rio). 



Oblong, brown ?, covered above as well as beneath with a scaly crust 

 of a pale yellowish or greenish grey, with very short hooked hairs, 

 particularly on the margins of the prothorax and elytra, curving for- 

 wards on the former, and backwards on the latter ; head (including the 

 peduncles) narrower than the prothorax, this with seven well-marked 

 but obtuse teeth on each side; scutellum punctiform; elytra a little 

 wider posteriorly, each with three very slightly raised gibbosities near 

 the suture, another at the shoulder, and externally towards the apex 

 two or three more, but which are considerably less prominent ; antennas 

 pitchy, shorter than half the length of the head ; legs pitchy ; eyes 

 dark brown. Length li line. 



In one of the two specimens now before me, the hairs are scarcely 

 evident even on the margins, being, apparently, more enveloped by 

 the scaly layer described above. In Mr. Fry's collection. 



Ethelema [Colydiidse]. 



Head vertical, rounded anteriorly, and prolonged at the side into a short 

 peduncle bearing the eye. Antennae as in Acropis, but more robust. 

 Labium short, transverse, fringed with long hairs. Maxillary palpi 

 robust, the terminal joint short, stout, obliquely truncate ; the labial 

 with the two basal joints small, the third large, broadly subovate, 

 slightly truncate. Mentum quadrate, very large. Prothorax as broad 

 as the head, transverse, regidar and convex above, nan-owed anteriorly, 

 the sides margined. Elytra oblong, nearly parallel, the surface smooth 

 and regular. Legs rather slender ; tibias not ciliated externally, ter- 

 minated by two short spines. Prosternum produced behind. 



The above include the characters which, combined with the total 

 absence of tubercles, chiefly separate this genus from Acropis. 



Ethelema luctuosa. (PI. VIII. fig. 6.) 



E. oblonga, hirta, nigra, flavescenti-varia ; prothoracis marginibus den- 

 ticulatis, setosis. 



Hab. Brazil (Rio ; Para). 



Oblong, closely covered above with short scale-like black hairs, many 

 of which are curved backwards, more or less varied with pale yellowish 

 or white ; head not wider than the prothorax, a transverse depression in 

 front below the peduncles ; prothorax scarcely narrower than the elytra, 

 except at the base, the margins denticulate, each denticulation with a 

 short curved hair arising from its apex ; scutellum very transverse ; 

 elytra regidar, punctate-striate, the striae rather remote, the patches of
