notum, except anterior margin, and elytra varying much in color from 

 slaty blue tt> brown and bright red. Elytra sometimes bear a large 

 pruinose spot just back of the middle. Front orange with black median 

 and lateral lines. 



External genitalia: Female, last ventral segment longer than pre- 

 ceding, slightly narrowed posteriorly, posterior margin composed of three 

 lobes, the lateral ones distinctly longer than the median; pygofers broad 

 and short, sparsely covered with short, stout hairs and about equalled 

 by the ovipositor. Male, plates small, forming a triangle about as long- 

 as wide, half the width of the last ventral segment; pygofers tapering 

 posteriorly from the broad base, nearly twice the length of the plates; 

 pygofers bearing an upturned chitinous process on caudal margin. 



Internal male genitalia: Styles small for such a large species, pointed 

 at anterior end, with a very large process for attachment to connective, 

 slightly narrowed medially and then widened and narrowing to slightly 

 out-turned and pointed tip, bearing several stout hairs on distal third 

 of lateral margin; connective U-shaped with the loop very wide; oedagus 

 large, prolonged anteriorly to meet connective, and with a very large an- 

 terior process extending dorsad, main portion dividing at apex into 

 large rounded anterior process, a median smaller triangular one, and a 

 posterior, acutely pointed still smaller one, a posterior process, also ex- 

 tending dorsad, long and narrow; long, crooked, slender chitinous bars 

 extend down from base of anal tube to cephalo-dorsal portion of oedagus. 



Distribution: Found in the eastern part of the state, as 

 shown by the following map : 



Hosts: Taken sweeping among weeds. De Long took speci-
