indicated tooth ; intermediate tibite with two spines on the upper 

 side, posterior tibiae with one only. 



Female : Similar in colour to the male ; the mandibles are shorter, 

 not so robust, carinate outwardly, not convex above, bi-sinuate in- 

 wardly, bluntly dentate at middle, and with the labruni projecting- in 

 a sharp triangle; head bi-impressed, the impression divided by a 

 longitudinal not sharp carina and edged on each side by a similar 

 but more oblique costa ; it is much more foveolato-punctate than the 

 male's ; the prothorax is a little more ampliate and also more closely 

 and more distinctly punctured ; the elytra are broader than the base 

 of the prothorax, and the series of punctures on the elytra are more 

 distinct ; the fifth apical joint of the antennae is also slightly 

 pectinate. 



I am under the impression that Westwood mistook the female of 

 this species for a male. 



Length (exclusive of mandibles), 19i-22 mm. : width 9^-12 mm. 



Hah. Cape Colony (? Knysna, Cape Town). 



This species seems to be very rare in collections. I have only seen 

 four examples, two of each sex.

Mentum three times as broad as long, moderately arcuate in front 

 from side to side with the angles quite rounded ; ligula bi-lobate, the 

 lobes quite separate, slender, narrow, corneous and with a fairly 

 broad fringe of dense hairs ; apical joint of labial palpi nearly as long 

 as the two preceding, obliquely attenuate at base, sub-parallel but 

 slightly ampliate towards the apex where it is obliquely truncate 

 inwardly with the truncate part hollowed ; maxillary palpi long, 

 deeply grooved inwardly with the exception of the basal one, apical 

 one longer than the second, slender, flagelliform ; mandibles as long 

 as the head or longer ; head as broad as the pi^othorax, or only slightly 

 smaller in the male ; eyes divided in front and behind ; basal joint of 

 antenna" as long as all the other joints ; club tri-jointed, pubescent, 

 but with the seventh joint produced into an aculeate inward process ; 

 prothorax transverse, obliquely truncate laterally behind ; elytra slightly 

 convex, oblong ; prosternum with an intercoxal, well-developed pro- 

 cess ; suture of mesosternum and metasternum hardly distinct ; meta- 

 thorax wide, a little broader than long; anterior tibias irregularly 

 spinose outwardly but with two and sometimes three more developed
