Bates.—On a New Genera and Species of Heteromera. 298 
punctuation, coste, etc., obsolete at the apex ; lateral expanded margins 
very narrow, and concave only at the base; under side brown, closely and 
somewhat coarsely punctured, much more distinctly pubescent (especially 
on the abdomen) than on the upper side; flanks of prothorax sparsely, 
pronotum closely and coarsely, rugose-tuberculate : legs rather long, reddish- 
brown ; hind tibie a little sinuous, front tibize with the outer apical angle 
deenaty dentiform ; tarsi elongate; antennz and palpi BED 
Length 5} brs width of elytra 24 lines. 
Hab. New Cuieid. One example. 
Cilibe tibialis, n. sp. 
Oblong or (rarely) oblong-oval, convex, entirely dark brown, slightly 
shining, anterior border of the head more or less rufescent; epistoma 
broadly emarginate in front, the sides distinct from the antennary orbits, 
the angles broadly rounded ; head and prothorax rather coarsely and closely 
punctured, the interstices on the middle of the former, and on the sides ¢ of 
the latter, appearing a little elevated and somewhat reticulate ; prothorax 
strongly transverse, rather broadly and feebly, and usually alittle sinuously, 
emarginate at apex; front angles not at all prominent, convergent; sides 
more or less rounded (ordinarily they are well rounded), more or less 
strongly incurved anteriorly from the middle, less strongly and a little 
sinuously posteriorly ; hind angles acutely produced, divergent; lateral 
margins not distinctly expanded, the edges very finely and almost uniformly 
thickened ; the three impressions by the basal border always obscure, some- 
times obsolete ; elytra oblong, or oblong-oval, the punctuation finer than 
on the prothorax and with a disposition to run together between the coste ; 
cost more or less distinct : the intervals, or interstices, more or less dis- 
tinetly reticulate-rugose at the base, sides, and apex; lateral margins 
narrowly expanded, usually not distinctly extending to-the apex, strongly 
reflexed at the base, rather coarsely transversely rugose-punctate ; flanks 
(save the lateral margins) of prothorax and sides of abdomen longitudinally 
wrinkled ; flanks of meso- and metasterna coarsely punctured ; abdomen 
finely finétared : ; under side shining black; epipleural fold and legs red- 
dish-brown, or piceous ; antennz elongate, and, together with the palpi, 
ferruginous ; outer apical angle of the interior tibie strongly dentiform. 
Length 6-7} lines ; width of elytra 2 —83 lines. 
Hab. New cee Seven Siniaplen: 
The apical emargination of the prothorax is distinctly more feeble in 
this species than in any of the others, and the front angles least prominent ; 
it is also the most convex, and, ordinarily, the most oblong, form. 
Cilibe impressifrons, N. sp. 
Oblong or elongate-oval ; ordinarily black, the elytra sometimes dark
