Onthophagus emeritus, n. spec, 

 Plate XXXV., fig. 31. 



Fuscous bronze, shining, hardly pubescent ; genae rounded but 

 bulging and sub-auriculate, clypeus semicircular, suture of genae 

 distinctly raised, a frontal carina slightly arcuate and uniting the 

 genae, and not far from it a second frontal carina very distinct in the 

 female and in the minor development, but less so in the great 

 development, the head is closely granular ; prothorax moderately 

 convex, not very ampliate laterally, closely punctulate, not impressed 

 longitudinally in the middle, and with the basal part rounded ; 

 ■elytra not very ampliate laterally, finely geminato-striate, the 

 strias closely punctulate, and the intervals plane and slightly aciculate, 

 second interval very slightly broader than the third, humeral callus 

 distinct ; pygidium roughly and closely punctulate ; metasternum 

 with a few scattered punctures and with a very distinct median 

 impressed line reaching from the base to the median part ; inner 

 part of tibiae non-spinose at apex, apical spur nearly straight in both 

 sexes. 



Male : Vertex with a rectangular lamina developing into a furcate, 

 compressed, divaricating process, deeply incised in the middle and 

 with the angles of the incision acute; in the smaller development the 

 laminate process, instead of being some 2|- mm. in height, is reduced 

 to an arcuate high lamina quadri-dentate but having the external teeth 

 a little higher than the two median ones ; the prothorax is declivous 

 m the anterior part, but has no tubercle on the top of the declivity. 



Female : Vertex with a high laminate carina slightly bi-sinuate, 

 and with the median part a little more raised than the outer angles ; 

 the prothorax is less convex in the anterior part, and has at the top 

 of the declivity two blunt tubercles set at some distance from one 

 another, but in some examples this median part is sub-carinate. 



Length 10-10^ mm. ; width 6-6|- mm.

pi. xiv., fig. 4. 



Male : Fuscous bronze, a little lighter on the head, and at times 

 also on the elytra, little shining, densely pubescent ; head shining, 

 clypeus elongate, sinuate laterally, deeply emarginate at apex and 

 with the angles of the emargination very distinct and a little reflexed, 

 the genae are ampliate, and the basal part of the vertex is produced
