triangular, closely punctate, bi-ini pressed between the eyes, and with a small 

 median fovea at the base, the labrum deeply emarginate. Prothorax abruptly, 

 obliquely narrowed from a little before the middle to the base, thus appearing 

 angulate laterally, the membranous margin extending forward to the point of 

 angulation ; densely, iinely punctate, with six oblong foveae on the disc, a small 

 ini])ression near the hind angles, and two others towards the sides anteriorly. 

 Elytra punctate-striate, the interstices polislied, sparsely, minutely punctulate. 

 Ventral surface opaque, the last two abdoaiiual segments shining. Legs 

 slender, short.

Hah. River Sarda Gorge, Kumaon {H. G. C: xii.1919). 



Two specimens, one of which has been sent for determination. 

 Smaller, narrower, and more shining than O. sexfoveatus, the prothoracic 

 constriction starting from nearer the apex, the margins less sinuate 

 towards the base and angulate antei'iorly, the eljtral interstices polished 

 as in O. nltidipennis. 



Ochthehius opacipennis, n. sp. 



Oblong, clothed with rather long, adpressed whitish pubescence ; obscure 

 aeneous above, black beneath, the legs and palpi (except at their tips) testaceous ; 

 the head and prothorax feebly shining, the elytra opaque. Head triangular, 

 den.-ely punctulate, with two deep foveae between the eyes and a small central 

 one at the base, the labrum unemarginate. Prothorax wider than the head, 

 sinuously narrowed from a little before the middle to the base, the membranous 

 margin extending to the basal half; densely punctulate, the disc with a narrow, 

 sharply-dehned, lanciform median sulcus, two deep foveae on each side of it, 

 and a sinuous groove towards the outer margin. Elytra oblong, finely punctate- 

 striate, the interstices somewhat convex, densely, minutely punctulate, dull. 

 Ventral surface opaque, the last two abdominal segments shining.

Hah. W. Almora, Kumaon {H. G. C). 



Two specimens. Narrower than 0. sexfoveafus, the vestiture 

 longer, the labrum entire, the prothorax with the two foveae on the 

 median line replaced by a narrow lanciform sulcus and the basal con- 

 striction starting from before the middle, the elytra opaque. Smaller 

 and narrower than O. nohilis, the el^'tra shorter, opaque, and finely 

 punctate-striate, the vestiture sparser; O. opacipennis can be placed 

 under the same section of the genus, Bothochius. 



Ochfhebius nohilis Villa. 



This is the commonest species of the genus along the Kosi and 

 other streams in Almora. The specimens sent vary considfrably in size,
