new Species of Histeride. 381 
epistoma, there is a stria over the eyes; the thorax is micro- 
scopically rugose (the head is less distinctly so), the punc- 
tures are smallest behind the neck, all are more or less 
ocellate, the marginal stria is complete, sides sinuous and the 
marginal rim behind the middle of the neck is slightly 
elevated ; the elytra are wholly sculptured like the thorax 
and there is no smooth margin along their bases, which is 
frequently the case in this genus; the pygidia are sculptured 
like the elytra, in ¢ the apex is circularly flattened and near 
the middle of the circle is a smail but conspicuous acuminate 
tubercle, with smaller and less distinct muricate processes 
round the edge of the flattened circle; the prosternum, the 
keel is broad and feebly sinuous and narrowly marginate 
anteriorly ; the mesosternum anteriorly has a narrow smooth 
border, but there is no stria, all the sternal plates have large 
shallow punctures, very evenly but not closely set together ; 
the first abdominal segment has similar points also; the legs 
‘are reddish brown, anterior tibizw 6—7-dentate. 
Hab. N.W. India (#. P. Stebbing). Only the male is 
known. 
Teretriosoma cristatum, sp. n. 
Cylindricum, piceum, nitidum, undique punctatum ; fronte minute 
foveolata ; elytris transversim basi haud impressis ; pygidio con- 
vexo; prosterno utrinque breviter sulcato; mesosterno antice 
immarginato; tibiis anticis 6—7-denticulatis. 
L. 22 mill. 
Cylindrical, thorax rather more convex than the dorsal 
region, piceous, shining, the scape of the antenne in J 
bearing long palish hairs; the head, vertex minutely foveo- 
late, epistoma rather broad and truncate anteriorly, surface, 
except in the region of the fovea, rather coarsely and rather 
densely punctured, striate over the eyes; the thorax, anterior 
~ angles obtuse and depressed, very feebly sinuous laterally, 
lateral stria well-marked but is not traceable behind the head, 
the punctuation is smaller than that of the head and less 
dense, especially on the disk and behind the neck; the elytra 
are wholly punctured, similarly to the densest part of the 
thorax, and there is no basal smooth border; the propygidium 
and pygidium are wholly punctured like the elytra, except that 
the pygidium is somewhat rugose at the apex, the propygidium 
has a faint longitudinal median impression, the pygidium is 
almost circular inoutlineand convex; the prosternum is coarsely 
and evenly punctured, before each coxa there is a short longi- 
tudinal furrow, but it is not in the place nor does it seem to 
correspond with the ordinary striz on the keel in Teretraus ;
