FROM CENTBAL WESTERN AEUICA. 75 



were published by me iu the " Transactions of the Entomological 

 Society" (vol. ii. p. 84), read August 2nd, 1852, and four additional 

 species were added by me in the "Transactions" of the same 

 Society (vol. iii.), read July 3rd, 1854. I have now the pleasui'e 

 of adding another new species of the genus Paussus, very remark- 

 able in several of its structural details, and which belongs to the 

 African section of the genus with a bipartite prothorax and an 

 excavated clava to the antennae. 



Paussus Murraii, Westio. 



P. prothorace bipartito clavaque antennarum postice excavata ; piceo-rufiis, 

 sub lente crebeiTune puiictatus, capite inter ociilos transverse elevato et in 

 medio fossulis cluabixs minimis transversis impresso, angulis posticis parte- 

 que postica prothoracis extus porrectis et fere latitudine elytrorum, podice 

 setis longis marginato.

This species is distinguished at once from every species hitherto 

 described in the peculiar form of the clava of the antennae and 

 prothorax. The upper side of the head is sloping and slightly 

 concave from between the eyes to the fore margin, which is 

 slightly emarginate and a little depressed. Between the eyes the 

 head is raised into a transverse ridge, in the middle of which are 

 two very miiiute impressions placed transversely with raised 

 black edges : the hinder margin of the eyes is furnished with some 

 porrected bristles : the antennae have a thick and somewhat pris- 

 matical basal joint, and the clava is large, being about equal in size 

 to the prothorax ; it is navicular, the front margin or keel being 

 acute, with three deep transverse impressions within the margin. 

 The inner basal edge is very deeply incised close to the insertion 

 of the clava upon the basal joint, the remainder of this margin 

 forming a long and acute angle, the outer edge of which extends 

 to the base oif the deep boat-like excavation ; the upper edge of 

 this excavation is very slightly crenated ; the lower edge on the 

 contrary is more irregular, being deeply emarginate at its base, 

 the emargination clothed with strong bristles, and oblique from 

 the middle to the apex of the antennae, which is rounded ; within 

 the posterior margin the excavation is marked with four deep 

 transverse impressions ; the hind part of the head is narrowed 

 into a neck. The prothorax is strongly bipartite ; the anterioi* 

 portion is the shorter, having a sharp ridge running across it, with
