Niponius canalicollis, sp. n. 
Cylindricus, elongatus, niger, nitidus, punctatus; fronte obtuse 
cornuta; thorace in medio longitudinaliter profunde canaliculato ; 
propygidio pygidioque conspicue bifoveolatis; prosterno mar- 
ginato, striis postice conjunctis. 
L. 33-43 mill. 
Cylindrical, elongate, black and shining, tarsi palish; the 
head is somewhat robust, sulcate between the cephalic pro- 
jections, which are smaller and shorter but relatively wider at 
the base than those of N. impressicollis, Lew.; the projec- 
tions also are less conspicuously transversely carinate, the 
punctuation on the surface is clear and fairly close, and closer 
and more irregular at the middle of the base; the thorax has 
a very conspicuous median channel, which sometimes reaches 
the base but is always somewhat shortened in front, on either 
side of the channel the surface is uneven and the punctures 
irregular in size and form; the elytra, the sutural and one 
humeral stria are complete, the others punctiform or obsolete. 
The dorsal striz in the species of this genus do not usually 
provide specific characters. ‘The fovee in the pygidia resemble 
those figured for N. osortoceps (Trans. Knt. Soc. Lond. 
pl. vili. 1885), but they are larger and more circular in out- 
line ; the prosternum, the keel is margined with a stria very 
clearly joining at the base, anteriorly the strie are shortened 
before the suture, and at the suture there is a transverse 
impression ; the meso- and metasterna are deeply canalicu- 
late in the middle and the metasternum is laterally striate, all 
the sterna are sparsely punctured ; the tibie are rather slender, 
resembling those ot osorzoceps, Lew. ‘The tibiew of N. An- 
drewest, Lew., another indian species, are much broader.

Pachycrerus preliaris, sp. n. 
Ovalis, parum convexus, ceruleo-metallicus; antennis pedibusque 
piceis; pronoto stria marginali post capite interrupta; elytris 
striis 1-4 integris, 5 apicali, suturali basi abbreviata; prosterno 
bistriato; mesosterno stria integra, arcuata; tibiis anticis 4- 
dentatis, dente apicali minute bifido. 
L, 33-33 mill. 
Oval, somewhat convex, metallic blue; the forehead feebly 
convex between the eyes, impressed anteriorly, marginal stria 
well-marked and rather more arched anteriorly than that of 
P. cyanescens, Er., surface sparsely punctured, punctures
