the apex sub-bifid owing to the presence of a longitudinal channel 

 which commences obsoletely close to the base, and gradually 

 deepens to the apex. The disc of the elytra is punctured uni- 

 formly with that of the prothorax, and also bears some much 

 coarser puncturation, which has a tendency to run in rows, these 

 rows seeming here and there to be placed in feeble striae ; the 

 lateral portions of the elytra and also the apex are devoid of 

 puncturation, but are sculptured with a well-developed system of 

 coarse transverse wrinkles, commencing behind the post-humeral 

 contraction; the apices are separately rounded; the suture is 

 convex near the apex, but not at all produced behind. The 

 pygidiuni is sparingly strigose and sparingly furnished with 

 rather short hairs. The sternal portion of the undersurface is 

 strongly and sparingly punctured (the flanks of the pro- and meso- 

 sterna being strigose), the metasternum most strongly ; of the 

 ventral segments the first is transversely strigose on either side 

 at the base, the rest are almost devoid of sculpture except that 

 segments 2-5 are longitudinally concave in the middle (probably 

 in one sex only) the concavity being punctulate and hirsute, that 

 .segments 4 and 5 have a transverse ciliated line of punctures 

 on either side, and that segments 1-4 bear on either side a closely 

 and finely punctured opaque space (very likely tomentose in a 

 fresh specimen), which is subquadrate on segment 1 and tri- 

 angular on the rest ; there is similar sculpture on either side of 

 the pygidium ; the sterna are sparingly and shortly hirsute. The 

 front coxse and femora and the four posterior femora and tibite 

 have their undersurface densely clothed with long pale hairs 

 C? in both sexes), and the front tibiae (perhaps in the female 

 only) are tridentate, the upper tooth very much smaller than the 

 others. The antennal club in the specimen before me (probably 

 a female) is a little shorter than the length, in front of the eye, 

 of the clyi)eus. The mesosternai process protrudes forward 

 beyond the front of the intermediate coxae nearly as far as the 

 length of the basal 3 joints of the front tarsi, and is thick and 

 somewhat cylindric at its base ; in shajje it i-eserables the same 

 part in Poly stigma punctata^ Don., but is longer and stouter.
