parallel to the middle, then attenuate to the tips, not mucronate at the 

 tip. Antennae with joint 3 longer than 2 and distinctly shorter and nar- 

 rower than 4, joints 4, 5 and 6 not twice as long as broad and strongly 

 serrate, joint 11 simply constricted a little beyond the middle (text fig. 2 c). 



Aedeagus with median lobe attenuate at tip, spatulate concave above, 

 distance between margins of spatula, equal to diameter of lateral lobes at 

 that point. Median orifice the diameter of median lobe, at that point, 

 from tip. Lateral lobes attenuate from base, distal spine small declivious. 

 No lateral spine. 



Male, 12 to 17 mm. long, 3.5 mm. to 5 mm. wide. 



Female, 18 mm. long, 5.5 mm. wide.

(Plate III, figs, a, ft.) 



Sides of the prothorax convergent from the base, slightly rounded, 

 posterior angles acute and divergent, prominent conical tubercle on the 

 base of the pronotum in front of the scutellum, the pronotum some times 

 bearing impressions and some times without them. The luminous vesicles 

 as near the lateral border as the posterior border of the posterior angles 

 and distinctly visible from below. Cotor from pale reddish to almost 

 black, the vestiture dense, grayish yellow and quite long. The elytra 

 attenuate posteriorly and not mucronate. Antennal joint 3 longer than 

 2, and distinctly narrower and shorter than 4; joints 4, 5 and 6 distinctly 

 serrate and not twice as long as broad; joint 11 simply constricted at 

 outer third. Antennae of the male (text fig. 2 a) little, if any, longer than 

 the pronotum. 



Aedeagus with median lobe strongly narrowed at tip, declivious, convex 

 above, median struts visible when lateral lobes are closed. Median orifice 

 twice diameter of median lobe, at that point, from tip. Lateral lobes 

 parallel from base to outer third then suddenly narrowed to tip. Distal 

 spine strongly declivious; no lateral spine. 



Female and male, 14 to 19 mm. long, 4 to <> mm. wide.
