Cherostes Gahani } sp. n. 



Robust, broad, clothed with light brown tomentum. Head 

 rather narrow, the antennal tubercles separated by a narrow 

 channel. Antenna? stout, extending to two thirds the length 

 of the elytra ; the basal joint dark brown, the rest lighter 

 brownish grey. Thorax dark brown, with impressed parts of 

 the disk lighter brown ; lateral tubercle obtusely conical. 

 The disk with a small median tubercle in front of the middle, 

 somewhat the shape of the figure 8, and behind the middle i3 

 an oblong raised space, divided by an impressed line down 

 its centre ; on each side of the disk is an oval tubercle, and 

 beyond this (nearer the anterior angle) there is a smaller 

 round obtuse tubercle. Elytra broad, parallel-sided, only 

 very slightly narrowed before the middle. The basal area is 

 strongly punctured, the punctures about the shoulder rather 

 large and often confluent; the punctures about the scutellum 

 smaller; the punctures gradually diminish in size and dis- 

 appear soon after the middle. The basal quarter is very dark 

 brown, but there is paler pubescence about the scutellum. 

 There is a broad pale brown fascia about the middle, some- 

 what M in outline ; behind this the surface is again dark 

 brown ; the apical area pale brown, the pale colour ascending 

 at the suture, with a dark brown spot at a short distance 

 from the apex. Abdomen speckled with dark brown. 

 Length 15 lines. 



Prosopocera uniformis, sp. n. 



Robust, subcylindric, dull, entirely clothed with sordid 

 brownish-ochraceou3 tomentum. Antenna? and legs rather 

 greyish. Thorax with an impressed transverse line in front, 

 obtusely angulated in the middle, and with a similar recti- 

 linear line near the base ; the lateral tubercle small, acute. 

 Elytra uniform, convex, with a few black shining tubercles 

 at the extreme base, and with some black punctures below 

 the shoulders. Mesosternal process slightly prominent, 

 slightly angular at its apex, longitudinally impressed in the 

 middle. 



Length 12 lines. 



Idactus albo-variegatus, sp. n.
