In form intermediate between T. hcemorrhoidaUs, Dj., and T. globulus, Dj. 

 As convex as tlie latter, but much more slender, the tliorax especially being 

 narrower (much narrower than the elytra), more cordiform, and the elytra 

 more ovate and rounded at the shoulders. The antennae are wanting in both 

 my specimens.

I have not again received either of the above species. They form a distinct 

 section, near Peryphus, distinguished by the setiferous punctures of the fifth 

 as well as the third interstice of the elytra. In form they closely resemble the 

 European JB. eques ; but the thorax is smaller and still more cordate (similar 

 to that of the Lopha section). The frontal furrows are deep, and reach to the 

 level of the hind margin of the eyes. The fovea of the hind angles of the 

 thorax has no carina exterior to it. The anterior tarsi of the male have only 

 the basal joint dilated, parallelogram mical, as in Peryphus eques. 



Bemhidium rotundicolle, n. sp. 

 B. nilotico similis, cupreo-seneum, nitidum ; antennis basi pedibusque 

 piceo-rufis ; elytris utrinque versus apicem, ipsoque apice flavo-testaceis ; thorace 

 fortiter rotundato, basi angusta, marginibus angustis, postice nuUomodo 

 explanatis, angulis posticis vix conspicuis, fovea parva juxta angulura loevi ; 

 elytris punctato-striatis, extus, et apice minus impressis, interstitiis paulo 

 convexis, tertio bipunctato. Long. 1^ — 2 lin. M. 



M. Tarsi antici articulis duobus dilatatis, apice obliquis et fortiter intus 

 productis. 



Differs from the section to which B. niloticum belongs by the very narrow 

 margins to the thorax, not explanated behind, and with obtuse hind angles ; 

 the sides of the thorax are very strongly rounded, but the base is much 

 narrower than the apex ; the apical angles are not at all conspicuous.
