tiuiatc (larkpr not very densely pubescent, first joint slender, very slightly 

 thicker than the second and but one-fourth longer, more than three times as 

 long as wide, second slender, sub-cyliudrical, three-fourths as long as the 

 third which is very slender, slightly narrowed toward base, third to fifth 

 slightly decreasing in length and increasing in thickness, the latter about 

 twice as long as wide and almost cylindrical, sixth to tenth nearly equal in 

 length, shorter than the lifth, increasing in width, the former slightly longer 

 than wide, the latter one-third wider than long, sides moderately convergent 

 toward base, basal angles broadly rounded, eleventh nearly as long as the 

 ninth and tenth together, slightly wider than the tenth, somewhat abruptly 

 constricted toward the tip whicji is obliquely produced and acutely rounded, 

 outer joints somewhat distinctly compressed ; third joint of the maxillary

 than the second. Prothorax widest at one-fourth the length from the base 

 where it is about one-third wider than long ; sides not strongly arcuate ; 

 apex from above rather strongly arcuate, about one-half as long as the base 

 with the angles rounded and obsolete, basal angles slightly produced, right, 

 and not rounded from above, slightly obtuse viewed laterally and not 

 rounded ; base transverse and straight ; pronotum not punctate except in 

 the minute impressions left by the denuded pubescence, transversely very 

 minutely and feebly strigose. Elytra at base very slightly narrower than the 

 pronotum ; sides feebly convergent posteriorly and slightly arcuate, apical 

 angles rounded broadly behind ; together transversely and just visibly 

 emarginate behind; inner apical angles narrowly rounded; disk broadly 

 convex, very slightly wider than long, about as long as the pronotum, shin- 

 ing, densely finely and feebly imbricate, imbrications slightly longer than 

 wide, coarsely reticulate, very minutely punctato-asperate. Abdomen at 

 base as wide as the contiguous elytra, having a very few short, black setae 

 along the sides, and long black prominent setae on the sixth segment, ex- 

 cessively finely alutaceous. Legs rather long and slender, dark reddish-

The sixth ventral segment is narrowly ami roundly produced in 

 the middle, the edge of the almost semicircular produced portion 

 bearing six equal and stout porrected spines which are parallel, there 

 is also a very small obtuse projection of the edge at each side which 

 bears an extremely long black seta ; dorsal quadridenfale, middle 

 teeth projecting slightly beyond the lateral, acute ; middle notch less 

 deep than the lateral ; lateral teeth each bearing three stout black 

 discal setae, the terminal two very long, the middle pair each one,
