instructo; pygidium feminae breve, subquadratum, inerme; forcipis brachia elongata, 



depressa, fere recta; maris margine interno basi fortiter dentata, dente secundo in 



tertia parte apicali sito, dehinc denticulato, apice incurva; feminae dente basali obtuso, 



in dimidio apicali denticulata, et subincrassata.

Antennae dark testaceous, with 12 segments, the second very small and short, 

 the rest gradually lengthening, all cj^lindrical. 



Head smooth, black, the hinder margin slightly emarginate. 



Pronotum subquadrate, anterior border convex, the posterior gently rounded, 

 the sides parallel; prozona somewhat tumid, metazona depressed, with a faint 

 median carina. 



Elytra flattened, black, covered with very fine and minute punctulations, not 

 very dense; the lateral borders clothed with short stiff bristles. 



Wings long, black, of the same texture as the elytra. 



Feet clear yellowish, with fine yellowisch pubescence; the femora not notably 

 short nor very mnch incrassate. 



Abdomen red, blackish at the base, with the lateral tubercles fairly distinct; 

 finely and densely punctulate above; the venter more coarsely punctulate; the first 

 four ventral segments are paler in colour and less densely punctulate than the others. 



Pygidium of the male short, in the form of a blunt and stumpy triangle, thick 

 at the base and depressed as well as narrowed; the apex is depressed into a very 

 small flattened lobe, on the edge of which three very minute tubercles are just 

 distinguishable with a strong glass; in the female the pygidium is short and nearly 

 Square, not narrowed, nor depressed and quite smooth. 



The forceps of the two sexes have the branches elongate, nearly straight, 

 incurved at the apex itself, and very distinctly flattened, of a deep red colour; at 

 the base itself on the lower side of the inner margin there is a strong but blunt 

 tooth in both sexes; in the male the inner margin is smooth beyond this tooth to 

 about the second third of their length where there is a sharp tooth; beyond this 

 tooth the margin is denticulated; in the female, the inner margin is smooth in the 

 first third, and then somewhat incrassate and denticulate to the apex. The forceps 

 are clothed with a long fine pale pubescence in both sexes.
