part, and it is more closely punctate in the anterior part than in 

 the male, but in other respects it is similar. 



The spotless variety is rarer than the spotted and banded ones 

 but occurs also with it, and it is impossible to separate any of the 

 varieties above-mentioned as they gradually merge into one another. 



Length (horn excl.) 17-24 mm. ; width 11-14 mm. 



Hah. The whole of South Africa except the extreme end of the 

 South-western districts in the Cape Colony. 



Nothing is known of the habits of this species. It feeds on Acacia 

 gum, according to Mr. G. A. K. Marshall, but is found also " flying 

 round manure heaps " or near cattle kraals in the Cape Colony, 

 somewhat in the manner of Hhinocata.

Mentum broadly ampliate rounded and transversely truncate in 

 the anterior part at the base of the deep cavity for the insertion of 

 the palps, the fused ligular part greatly narrowed, being across less 

 than half the width of the mentum, and with the apex of the cavity 

 reaching nearly the rounded angle of the anterior part which is 

 broadly and very deeply incised ; maxilla? robust, inner lobe pro- 

 jecting and truncate at tip, very densely ciliate inwardly, upper 

 lobe slightly incurved, and with two superposed blunt teeth, densely 

 penicillate at the top and outwardly ; clypeus carinate laterally on 

 the upper side, parallel with the anterior angles projecting and the 

 anterior part truncate and produced in the middle into a short, 

 narrow process reflexed and furcate at the tip in the $ whereas in 

 the ? the outer angles are rounded and the median part is pro- 

 jecting and slightly sinuate ; antennal club not longer than the 

 pedicel in either sex ; prothorax with a sharp median tubercle in 

 the anterior part in the $ , diagonally ampliated laterally from 

 the anterior part to the middle, and only slightly attenuated thence 

 to the base the outer angles of which are not rounded, base semi- 

 circular and slightly emarginate above the scutellum which is 

 long, sharp, and grooved laterally, especially in the $ ; elytra 

 elongated, attenuate behind, not costate, the suture is only slightly 

 raised behind and weakly acuminate at apex ; legs bi- or tri-dentate 

 outwardly according to the sexes, spinose on the upper side of the 

 intermediate tibia? in the $ only, tarsi long, the two basal joints 

 of the posterior ones spinose inwardly and outwardly, the spine 

 more pronounced in the ? than in the 3 , in which sex the 

 first joint is slightly longer than the second, whereas they are of
