Figure 3. — Anterior tibia of male (A), clypeus (B), and last visible abdominal 

 sternite of male (C) and of female (D) of Clwysobotlwis lixa. 



Female. — Rather narrowly elongate, subcylindrical, moderately shining, 

 brownish black, with a distinct purplish tinge ; beneath piceous, with distinct 

 purplish and greenish tinges, and more strongly shining than above. 



Head uniformly purplish brown, with a vague, longitudinal carina on occiput ; 

 front slightly convex ; surface finely, rather densely, uniformly punctate, mod- 

 erately clothed with long, semierect, whitish hairs, the intervals nearly smooth ; 

 clypeus broadly, rather deeply, angularly emarginate in front, broadly rounded 

 on each side. Antenna purplish brown, gradually narrowed to apex ; inter- 

 mediate segments subtriangular, distinctly wider than long, broadly rounded 

 at outer margins ; third and fourth segments subequal in length. 



Pronotum twice as long as wide, subequal in width at base and apex, widest 

 at middle ; sides regularly rounded ; anterior margin slightly sinuate, with a 

 vague, broadly rounded, median lobe; base broadly, arcuately emarginate on 

 each side, the median lobe feebly produced and broadly rounded ; disk strongly 

 convex, without callosities or depressions ; surface coarsely, deeply, rather 

 densely punctate, sparsely clothed with long, erect, inconspicuous hairs, the 

 intervals indistinctly granulose. 



Elytra scarcely wider than pronotum, twice as long as wide, widest behind 

 middle : sides slightly diverging from humeral angles to behind middle, then 

 arcuately converging to tips, which are separately broadly rounded ; lateral 

 margins coarsely serrate; basal depressions deep; humeral depressions broad 

 and shallow: disk moderately convex; surface coarsely, densely punctate, rather 

 densely clothed with short, erect, white hairs, the intervals indistinctly granu-
