Form: A large, cylindric, elongated form. Length, 8 to 9 mm. Vertex, 

 wider than long, two-thirds length of pronotum, roundingly acutely 

 angled. Pronotum narrowed anteriorly with lateral and humeral angles 

 about equal, posterior margin distinctly emarginate. Elytra long and 

 narrow. 



Color: Face yellow, separated from orange-yellow vertex by broad 

 black line on margin. Vertex with two, small, black marginal lines be- 

 fore the ocelli, and frequently the posterior half reddish or green medially. 

 Pronotum red with narrow light green band on anterior margin, and a 

 posterior large dark green W, with outer arms turned mesad. Elytra 

 red with costal, claval and sutural margins and median stripe on corium, 

 green, the apex and appendix black. 



External genitalia^: Female, last ventral segment slightly longer than 

 wide, lateral margins slightly narrowed posteriorly, posterior margins 

 broadly rounded and medially produced; pygofers long and narrow, 

 equalling ovipositor and bearing a few coarse hairs on either side of 

 median line. Male, plates long, broad at base but apically greatly pro- 

 duced and concavely tapering to long acute tip, lateral margins bearing 

 stiff hairs; pygofers long and narrow, greatly exceeding plates and 

 covered with numerous coarse hairs. 



Internal male genitalia: Styles tapering at anterior end, curved out- 

 ward medially and ending in distinctly out-turned apices ; connective slen- 

 der, Y-shaped; oedagus with triangular body when viewed laterally, a 

 long, slender process leaving it from near distal end, and a still longer, 

 heavier one extending dorsad from the distal apex; a V-shaped chitinous 

 bar at base of anal tube.
