Bares.—On a New Genera and Species of Heteromera. 285 
cately punctured, the anterior obliquely truncated at the outer side at apex ; 
hind tibix quite straight ; tarsi and antennew reddish-brown ; joint eight of 
_ the latter subpyriform, nine and ten a little transverse, subturbinate, eleven 
large, broadly rounded at apex. 
Length 83-9 lines ; width of elytra 41—43 lines. 
Hab. New Seiad, 
There is a very great amount of individual variation in the species of 
this genus in the form of the prothorax (especially) and elytra, and in the 
amount and intensity of the punctuation, ete. of their surface. 
In one of the three examples of the present species before me (possibly 
a female, as similar differences exist in individuals of the other species 
whereof a series has been obtained), the form is more expanded or more 
broadly oval, the head and prothorax are broader in proportion to their — 
length, the sides of the latter, instead of gradually narrowing in a slight — 
curve from base to apex, are subparallel to a little beyond the middle, - 
thence rapidly curvedly narrowed to the apex; besides the two ordinary 
fovex at each side of the middle, at the basal margin, there is also a broad 
transverse line or depression, feebly arched, subparallel and near to the 
basal margin ; the elytra are broader and less narrowed behind, and the 
base is squarely truncated; and the punctuation on the prothorax and 
elytra (especially on their disks} $ is more dpen. 
Altogether the largest, most expanded and opaque, and least convex form 
in the genus. 
Cilibe nitidula, n. sp. 
Very near to the preceding, and of the same sate but smaller ; the 
the colour black ; the entire upper surface much smoother, and abiaita 
the punctuation face and more open, the interstices less distinctly elevated 
and reticulate : the elytra do not present the shagreened appearance seen 
in the preceding; they are more, and very distinctly, convex behind the 
middle, and consequently more abruptly declivous behind; on the under 
side the punctuation and the rugosities on the flanks of the prothorax and 
on the abdomen are similar but stronger ; the hind tibiw are feebly but per- 
ceptibly sinuous ; antenna, etc., as in ©. opacula. 
In the single example of his species before me, the head is distinctly 
impressed on the crown ; the prothorax is gradually and slightly curvedly 
narrowed from base to apex; the apex is strongly arcuately (and feebly 
sinuously) emarginate, the front angles prominent, subacute, and directed 
forwards ; the base is strongly bisinuate, the hind angles prominent, acute, 
and slightly outwardly directed ; the lateral margins are expanded (but less 
broadly so than in the otending) and slightly refiexed or concave, the edges 
irregularly thickened, and the base aud apex margined at each side only.
