Genera and Species of Coleoptera. 107 



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



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

 brevioribus. 



Hab. Brazil (Rio). 



Oblong, browii ?, 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 pro thorax 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; scutellimi punctifonn; elytra a little 

 wider posteriorly, each with three very slightly raised gibbosities near 

 the sutiu"e, another at the shoulder, and externally towards the apex 

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

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

 dark brown. Length IJ- 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. Antennjje 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 quadi'ate, very large. Prothorax as broad 

 as the head, transverse, regular and convex above, narrowed anteriorly, 

 the sides mtu-gined. Elyti-a oblong, nearly parallel, the surface smooth 

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

 minated by two short spines. Prosternmn produced behind. 



The above include the characters which, combined with the total 

 absence of tubercles, chiefly separate this genus from Acropis. 



EtJielema hictuosa. (PI. VIII. fig. 6.) 



^. 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 cm-ved backwai'ds, more or less varied with pale yellowish 

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

 fi'ont below the peduncles ; prothorax scarcely nan-ower 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 regular, punctate-striate, the striaj rather remote, the patches of
