part of the femur, posterior tibiic long, slender for one-third of the 

 length, and gradually dilated from there. The length of the upper 

 and lower spines of the posterior femora varies, and I have seen 

 a male example in which the intermediate femora have a long apical, 

 hardly incurved tooth, while the median part is hardly incised, and 

 is crenulate ; in the small development, the carina under the fore 

 tibiae is not so sharp at base, and the spine on the upper edge of the 

 posterior femora is wanting. 



Female : Clypeus distinctly aculeate, tubercle on vertex of the 

 head a little more pronovuiced than in the male ; anterior tibice 

 strongly quadri-dentate, intermediate femora distinctly serrate 

 beneath. 



Length 17-20 mm. ; width 9-11 mm.

Black, shining, somewhat depressed ; head granulose, clypeus 

 slightly plicate transversely, more distinctly so in the female than in 

 the male, no clypeal carina, frontal one curved, very distinct, basal 

 one not quite so much raised, sinuate and having in the centre 

 a short, but distinct tubercle, genaj rounded ; prothorax ampliated 

 diagonally laterally from the anterior angle to past the middle, and 

 more abruptly attenuate from there to the base, marginate in front 

 and laterally, but not at base, covered with moderately closely set 

 punctures, while the two basal impressions, which are moderately 

 deep and sometimes coalesce, are filled with small granules ; 

 scutellum distinct, sharp ; elytra sub-parallel, very slightly sinuate 

 laterally, humeral callus showing very little, striae narrow, intervals 

 nearly plane and deeply punctured ; pygidium slightly punctured ; 

 metasternuni granular, median part with a smooth longitudinal 

 band . 



Male : Clypeus rounded ; anterior tibiae long, arcuate, quadri- 

 dentate outwardly, the teeth somewhat blunt, the basal one 

 especially, and the mucro short, a little incurved, and densely 

 ciliate ; underneath the carina is produced at base into a more or less 

 sharply triangular tooth ; anterior femora simple, intermediate ones 

 crenulate beneath, posterior ones with a sharp tooth underneath at 

 middle, intermediate and posterior femora simple.
