184 BiacksurN AND SHARP—On some New Species and Genera of Coleoptera. 
OopEMAS. 
Oodemas tardum, n. sp.—Oblongo-ovatum ; nitidum; nigro-zneum ad viridem 
accedens, antennis tibiis tarsisque plus minusve rufescentibus; oculis prominulis ; 
rostro haud sequaliter arcuato, fortiter punctato rugatoque; antennis rostro capite 
prothoraceque conjunctis paulo brevioribus, scapo clongato, funiculi articulo primo 
brevi secundo elongato ; prothorace transverso, antice angustato, distincte crebrius 
punctato; elytris thorace sat latioribus, antice vix, postice obsolete, striatis, parce 
fortiter seriatim punctatis, interstitiis confuse subtilius punctatis ; subtus abdominis 
parte anteriori minus fortiter punctata. Long. 5-53 m.m. 
This insect resembles O. infernum, mihi, but is readily distinguished by the 
peculiar shape of the rostrum (which, instead of being slightly and quite regularly 
arched from base to apex, appears to be almost angularly bent downwards from the 
middle) by the much darker colour, and by the greater distance apart (in the rows) 
of the larger punctures on the elytra. 
A few specimens were taken from the bark of a tree, at an elevation of about 4000 feet, on 
Haleakala, Maui.

Oodemas equale, n. sp.—Oblongum; nitidum; zneum, antennis pedibusque 
plus minusve rufescentibus vel testaceis; rostro brevi, distincte subtilius punctato ; 
oculis vix conyvexis; antennis rostro capite prothoraceque conjunctis sat evidenter 
brevioribus, scapo brevi, funiculi articulis primo et secundo subzequalibus sat 
elongatis ; prothorace leviter transverso, antice angustato, obscure subtilissime 
punctato; elytris prothorace latioribus, vix evidenter striatis, parce nec fortiter 
seriatim punctatis, interstitiis parce subtiliter punctatis; subtus abdominis parte 
anteriora parce subtiliter punctata. Long. 4—43 m.m. 
This species is remarkable for the exactness with which the base of the thorax 
is applied to the elytra, so that the curve formed by the side of the thorax and elytra 
(viewed from above) is almost perfectly continuous. This character readily 
distinguishes it from O. obscurus, mihi which in some respects it resembles. The 
apex of the last segment in the male is abruptly truncate, in the female is 
rounded. 
A short series was obtained by beating branches of trees, at an elevation of about 2000 feet, on 
Lanai. 
TBs 
Oodemas crassicorne, n. sp.—Oblongum; elongatum ; nitidum; zeneum, anten- 
nis pedibusque rufescentibus; oculis subprominulis; rostro brevi, obscure minus 
subtiliter punctato; antennis crassiusculis, rostro capite prothoraceque conjunctis 
sat evidenter brevioribus, scapo brevi, funiculi articulo primo brevi, secundo 
elongato; prothorace transverso antice angustato, obscure subtiliter punctato ;
