of the first, second, and third intervals, and those on the fifth and 

 seventh are scarcely distinct ; propygidium, with two sub-parallel 

 series of transverse folds fairly broadly divided in the centre by a 

 smooth space ; pygidium shagreened but with the apical convex part 

 sometimes slightly aciculate, fold of pygidium very broad at middle, 

 and having in the centre a deep, transversely ovate excavation in 

 the male ; intermediate abdominal segments without a row of 

 punctures ; metasternum not deeply impressed, but distinctly 

 grooved longitudinally ; prosternum with the basal process some- 

 what rounded but very projecting ; anterior tibiae with an inter- 

 mediate serrate tooth and three more above the digitation ; inner 

 claw of male a little acuminate but not emarginate outwardly.

Black, very shining ; palpi, pectus, and legs dark chestnut ; head 

 nearly smooth above the clypeal transverse ridge which is entire, very 

 distinct, slightly flexed in the centre, frontal carina merged with the 

 clypeal, except laterally, clypeus very rugose, especially in the 

 centre, sharply bi-dentate at apex ; prothorax attenuate laterally in 

 front for about one-third of the length, not quite parallel from there 

 to the posterior angle, moderately convex and smooth ; scutellum 

 sharply ogival, impunctate, and impressed longitudinally in the 

 centre in the male only ; elytra sub-parallel for a little more than one- 

 third of the length where they are slightly sinuate, and moderately 

 ampliate from there to the posterior rounded part ; the strite are 

 deeply punctured, the second one does not always reach quite to the 

 base, the second interval has numerous punctures stretching from 

 base to apex, the fourth, fifth, and sixth have a short series of 

 moderately distinct punctures in the posterior part, and the apical 

 margin is deeply and broadly pitted ; stridulating striae forming on 

 the pygidium a broadly truncate cone ; pygidium very rugosely 

 shagreened transversely for half the width, the lower half being 

 quite smooth, second, third, fourth, and fifth abdominal segments 

 with a lateral series respectively of eight, four, and three setigerous, 

 deep punctures ; fold of pygidium narrow, simple at middle ; meta-
