of the impression to a very short distance from the base, and the 

 antei-ior margin is shglitly sinuate at middle, but not recurved; 

 scutelhun closely and deeply punctate in the anterior part only from 

 base to middle; elytra punctato-striate, eighth and ninth striue of 

 equal length and reaching the base of the humeral tubercle ; anterior 

 tibiffi six-dentate ; legs and under side very densely pubescent.

BOLBOCEKAS AUSPICATUM, n. SpeC, 



Plate XXXVI., fig. 21 ; Plate XXXIX., fig. 3. 



Light testaceous red, shining ; labrum transverse, not emarginate ; 

 clypeus short, transverse, sharply tuberculate at tip, head sharply 

 and strongly carinate laterally and having a widely triangular carina, 

 tubercular at base and at apex, and extending from the basal angles 

 of the clypeus to the apical marginal tubercle, in the posterior part, 

 and in a line with the median part of the eyes, there extends a 

 highly raised sharp carina reaching from side to side, the head is 

 somewhat pubescent, impressed in the median part, and is not very 

 closely punctate ; prothorax vertical in front, deeply and moderately 

 broadly excavated vertically on each side of the perpendicular median 

 lobe which is transversely carinate at tip, but with the upper part of 

 the excavation sinking deep near the median part of the disk, and 

 edged there laterally by a toothed, compressed laminate ridge, in 

 the median part of the upper part of the disk there is a well defined 

 longitudinal groove reaching close to the base, and the surface is 

 deeply but not very closely punctured ; the punctures are rounded, 

 and more crowded in the centre of the sides, and in the anterior 

 part of the median lobe ; scutellum almost impunctate ; elytra deeply 

 punctato-striate, intervals impunctate; eighth and ninth striae of 

 equal length and reaching well on to the humeral tubercle ; anterior 

 tibiae six-dentate ; iinder side and legs densely pubescent. 



Female: Like the male, the only difference being in the shape 

 of the prothorax the anterior part of which is merely slightly im- 

 pressed laterally, and not excavate ; the punctures are also denser 

 and a little more rugose. 



Length 6-8 mm. ; width 4-5 mm. 



This species is very distinct from all the other South African ones, 

 and has no ally so far as is now known. 

 Hah. Natal (Newcastle, Frere).
