Male : Very light flavous, shining ; clypeus semicircular and 

 having some fine, shallow, somewhat scattered punctures, suture 

 somewhat arcuate but nearly obliterated in the centre, frontal carina 

 straight, the space between the clypeal suture and the carina is 

 somewhat deeply punctate laterally, but there is only a few scattered 

 punctures on the centre, the vertex is closely and somewhat deeply 

 punctured except along the base, which is smooth ; prothorax 

 ampliated and rounded laterally, basal angles broadly rounded, outer 

 margin very slightly serrulate, covered with nearly contiguous small 

 punctures, each bearing a very long, appressed flavous hair, the 

 whole forming a somewhat dense pubescence ; scutellum almost 

 impunctate, but clothed with long appressed hairs springing from 

 the base ; elytra narrower in the anterior part, sinuate laterally 

 before the median, and somewhat ampliated thence to the posterior 

 part, covered with closely set, fine punctures, and having no traces of 

 costules or striae except the juxta-sutural one ; the greatest part of 

 the propygidium is uncovered and finely aciculate, the slightly con- 

 vex, vertical pygidium is closely punctured in the median part only, 

 the sides being impunctate ; abdomen finely punctate, and having 

 few, scattered, long, fine appressed hairs, median part of the suture 

 of the segments somewhat obliterated ; pectus and femora very 

 densely villose ; anterior tibiae strongly tri-dentate outwardly, and 

 having a long, inner slender spur, tarsi long, slender, intermediate 

 tibiae with an oblique rudimentary, ciliate ridge in addition to the 

 median one ; posterior tibiae with the oblique ridge on the outer side 

 continued in a conspicuous tooth, apex dilated, strongly ciliate, the 

 two spurs laminate, the upper one dilated at the tip in the male, the 

 only sex known to me.
