emarginate, and the vertex raised into a protuberance and fur- 

 nished with a rather large simple cavity : antennae with the first 

 joint strongly punctate, and the club, viewed from the side, 

 elongate-quadrate and parallel-sided, as broad at base as at apex, 

 sharply keeled on one side and on the other deeply and broadly 

 excavate, the excavation with the margins obtusely dentate, and 

 with the setae of the lower margin short, basal exterior angle 

 strongly produced and broadly reflexed ; the whole club, except 

 the upper margin, is dull and very thickly punctured ; pronotum 

 shining, punctured, a little broader than long and a little narrower 

 than the head, with the base and apex of about equal breadth ; 

 the anterior part short, strongly raised, with the sides deeply 

 excised and bidentate, so that four teeth or prominences are evident 

 on the raised basal margin ; the posterior part deeply and broadly 

 impressed in front, with the depression smooth, longitudinally 

 channelled : elytra parallel-sided, rather dull, thickly alutaceous, 

 with their lateral margins furnished with long red setose hairs ; 

 pygidium with yellowish setae ; legs moderate, with the tibiae 

 slightly compressed, but not dilated. 



Length 6 millim. 



Burma : Momeit (Doherty). 



This species belongs to the P. denticulatus group ; it appears to 

 be easily distinguished from the species hitherto described by the 

 quadridentate basal margin of the anterior portion of the pronotum. 



Var. castanea, nov. 



Fig. 229. 



Paussus guadricoriiis 

 var. castanea. 



Larger than the type, entirely of a dark 

 castaneous colour, with the elytra rather 

 shiny ; the sides of the anterior portion of 

 the pronotum are not deeply excised but 

 are furnished with four distinct teeth or 

 prominences. 



Length 7| millim. 



Tenasserim : Mergui (Doherty). 



Type in the British Museum. 



It is possible that this may be a new 

 species. The surface is nearly bare of pubes- 

 cence, but it is probably rubbed, as the long 

 reddish setse are apparent on the extreme 

 margins. Described from a single specimen.

Paussus seriesetosus, Wasmann, Notes Leyden Mus. xxv, 1904, pp. 59 

 & 72, pi. 6, fig. 3. 



A small species, ferruginous, with the posterior angles of the 

 pronotum and the disc of the elytra black (sometimes the latter 

 are entirely black with the exception of the base and apex) ; head 

 and pronotum dull, coriaceous, the former with the clypeus slightly
