tips separated. Abdomen moderately convex and more or less im- 

 pressed on first two segments. Protibise suddenly and briefly sinuate 

 at base. 



FemdJc. — Rather broad. Antennse reaching- beyond the protho- 

 racic base, but shorter than in the male. Elytral disc arcuately de- 

 clivous posteriorly, not produced at apex, but more or less acute. 

 Abdomen quite strongly convex. Protibia) gradually narrowing at 

 base. 



MeasurernetUs. — Males: Length, 15-20.5 mm.; wadtli, 7.2-8 mm. 

 Females: Length, 14-19.5 mm.; width, 7-10 mm. 



Genital ('h(/racfers, male. — Edeagophore slender, elongate oblong- 

 ovate. 



Basale elongate oval, surface moderately convex, sides moderately 

 arcuate, apex deeply and triangularly emarginate to receive the base 

 of the apicale. 



Apicale slender and elongately triangular; surface evenly and 

 rather strongly convex, without groove ; sides nearly straight, gradu- 

 ally converging to apex, the latter acute; base strongly and acutely 

 lobed at middle, oblique and broadly sinuate laterally. 



Sternite subparabolic in outline. Each lobe subtriangular, external 

 border quite evenly arcuate to apex, the latter subacute, })rominent 

 and slightly produced ; internal border sinuate ; surface more strongly 

 convex along the external border, thence sloping inward, densely 

 punctured in apical tw^o-thirds, especially internally, setose, seta^ 

 quite long and dense, more so on apex. Sinus semicircular, membrane 

 not setose across the same. 



Female. — Genital segment (Plate 5, fig. 8) elongately triangular 

 with the apices, or triangular-trapezoidal Avithout the same. su]:)erior 

 surface plane, not setose. 



Yal villa. — Dorsal plate suboblong to feebly and elongately tri- 

 angular, slightly narrowing from base to apex ; surface plane, smooth, 

 and not noticeably punctate ; external border angulate at basal fourth, 

 thence more or less sinuate and arcuate to apical margin, the latter 

 subtruncate at middle two-fourths, angle rounded, in inner fourth 

 continuous with the surface of apex; internal margin quite straight 

 or more or less feebly arcuate. Apex chitinous, produced, and 

 everted, convex above and concave beneath, rounded at tip; fossa 

 at base of the external apical surface, beneath apical margin of dorsal 

 plate. 



Appendage mammilliform, glabrous, with a pencil of few quite 

 long seta" at tip. 



Basal promme7ices feebly evident, lateral surfaces of valves slightly 

 visible from above. 



Suj^erior pudendal memhrane attaining the apical fourth of the 

 dorsal plate, finely and longitudinally rugulose.
