Head distinctly transverse, very little wider across eyes than 



at extreme base; with a narrow depression between antennary 



ridges, and with two small intei-ocular foveae; coarsely and densely 



punctate. Antennae passing middle coxae, first joint subcylindri- 



cal, its base partially concealed, second slightly shorter and 



stouter than third, the others to eighth feebly decreasing in 



length, ninth about twice as long and twice as wide as eighth, 



^eath slightly larger than ninth, eleventh subovate, as long as 



ninth and tenth combined. Prothorax transverse, sides very 



little rounded, base not much narrower than greatest width, which 



is near apex; with a large, shallow, medio-basal impression, and 



a feeble subbasal one on each side; punctures as on head. Elytra 



widely transverse, much wider at apex than at base; dorsal striae 



traceable almost to apex; with several very feeble depressions; 



• coarsely and densely punctate. Abdomen with second and third 



segments large and dilated posteriorly, fourth parallel-sided, fifth 



anil sixth decreasing in width; lower surface with a large shallow 



depression. Metasternum densely punctate, flat in middle. Legs 



•rather long; front trochanters each with two small acute teeth of 



almost equal size; front femora acutely dentate near base; middle 



trochanters each moderately acutely dentate; four front tibiae 



-somewhat curved and obtusely spurred at apex, hind tibiae longer, 



Jess curved, and not spurred. Length 2^-2| mm. 



9. Diflers in having the antennae shorter, with the club some- 

 what smaller; prothorax with sides slightly more rounded, and 

 alxlomen gently convex on undersurface.

Readily distinguished from iV. varia by the front angles of the

 The clothing appears to be slightly maculate, but this is due more

 appear to be three very vague stripes. The palpi are peculiar;
