OXTHOPHAGUS PE^TOBTUS, 11. Sp. 



Dark coppery-bronze, very little shiny, antennae dark bronze 

 with the club black ; clypeus semi-circular, but slightly obtuse in 

 front and with the margin very slightly reflexed, deeply punctate 

 with the punctures coalescing along the margin, deeply depressed in 

 the central part in front of a highly raised transverse clypeal lamina 

 which is slightly arcuate but produced on each side into a sharp, 

 projecting angular process, and situated between the median part of 

 the eyes, there is no frontal carinule ; prothorax deeply sinuate 

 latsrally behind and with the posterior angles distinct, highly 

 convex, retuse in front, bi-impressed in the middle of the anterior 

 part, the two impressions surmounted by a small but very distinct 

 tubercle, and having in the centre a very deeply emarginate, almost 

 bi-tuberculate ridge, it is covered with very closely set scabrose 

 punctures in the median part of the disk, and with granules on the 

 other parts of the surface, and clothed with a very short, silky, 

 whitish pubescence, the base is plainly grooved, and the edge of the 

 margin has a series of punctures ; elytra not wider than the prothorax 

 at its broadest part, striae narrow and shallow, intervals plane, 

 closely punctured and pubescent ; pygidium nearly as broad as long, 

 covered with broad, deep, nearly equi-distant punctures, and clothed 

 with a dense greyish- white silky pubescence ; under side moderately 

 pubescent ; inner spur of anterior tibiae long, the basal part is 

 directed inwardly almost at right angles with the apex of the tibia, 

 and then curves strongly outwards. 



Allied to 0. dispcir, but different in colour and sculpture ; the shape 

 of the inner spur of the anterior tibia? of the male is very singular, 

 and unlike that of any other species of Ontlwplmgus known to me. 



Length 7-9^ mm. ; width 4|-5^ mm.

OXTHOPHAGUS DECEDEXS, n. sp. 



Head and prothorax light bronze, moderately shiny, the latter 

 with a fiavescent lateral patch, broad in the anterior part, narrower 

 behind and not reaching the posterior angle, the elytra are light 

 testaceous with the striae fuscous, pygidium and pectus bronze, the 

 legs sub- testaceous, and the abdomen darker than the pectus ; it is 

 covered with a short, very dense greyish pubescence longer in the 

 posterior part of the elytra, and very long and silky on the pygidium ; 

 clypeus slightly elongated, rounded in front with the anterior margin 

 reflexed, covered with deep, transverse setigerous punctures separated
