Sterna more or less dull, finely and not distinctly scul})tured. 



Parapleuroi smooth, rather sparsely but not very distinctly punctate. 



Ahdomen horizontal, ver}' finely and sparsely punctulate, obso- 

 letely rugulose and quite evenly convex. 



Lef/f< rather slender, moderate in length. Anterior femora nuitic 

 jn-otibial spurs similar in the sexes, the anterior slightly longer than 

 the posterior. Protarsi simple.

MeasuremeiiU. — Males: Length, 10-18 mm.; width, 1K5-10 nun. 

 Females: Length, 15-18 unu. ; width, *.)-10.r) nun. 



Genital cliaraeters^ male. — Edeagophore elongate oblong-ovate, 

 rather slender, feebly arched and slightl}' depressed. 



Basale oblong, very moderately convex, sides feebly arcuate. 



Apicide triangular, slightly depressed ; surface rather feebly con- 

 vex and without groove; sides nearly straight or feebly and broadly 

 sinuate to apex, the latter acute and not attenuated; base distinctly 

 subacutely lobed at middle, feebly and broadly sinuate laterally. 



Stent ite quite parabolic in outline. Each lobe rather long, with 

 external border more or less evenly arcuate or straight in basal half, 

 thence feebly arcuate to subtruncate to apex, the latter narrowly 

 rounded and rather prominent ; internal border oblique and short ; 

 surface scarcely convex, rather densely punctate in aj^ical two-thirds, 

 setose, seta^ rather long and not dense. 



Feinale. — Genital segment (Plate 5, fig. 7) triangular, rather elon- 

 gate, including apices, or subtrapezoidal without the same, surface

 l)unctate; external border more or less feebly arcuate and slightly 

 explanate; internal l)order arcuate; apical margin more or less trun- 

 cate, angle rather broadly rounded, internally continuous with the 

 surface of apex, not setose. Apex chitinous, produced, slightly 

 longer than the width of dorsal ])late at basal third, everted, convex 

 above and concave beneath, tip rounded, external boi'der feebly ex- 

 cavated at base and slightly beneath the apical margin of dorsal 

 plate, forming the fossa. 



Appendage somewhat spherically mammilliform, glabrous, with a 

 pencil of quite long seta? at tip. 



Basal prominences obsolete. 



Superior pudendal rnemhrrme attaining the middle of the dorsal
