the anterior margin, and another small spot on the humeral margin

 nervures interrupted with dark-brown before the middle. 



Genitalia: 9, ultimate ventral segment nearly twice wider than 

 long, posterior margin slightly curved, pygofers long, stout, f nir times 

 longer than the ultimate segment, tip of ovipositor exceeding the p\g-

Small and compact, broader and flatter than any of the preceding 

 species, vertex short and broad, two large dark spots slightly farther 

 from each other than from the eye, pronotum transversely rugulose, 

 short and broad, without distinct spots, elytra sub-hyaline with dark 

 nervures except at the base. Length, 3 mm.; width, 1.50 mm. 



Vertex about four times wider than long, over one-third the length 

 of the pronotum, margins broadly rounding, nearly parallel, posterior 

 margin not elevated, touching the pronotum throughout. Face broad, 

 genge very slightly angular. Front, width at base equaling length, 

 slightly narrowing to the middle where it is nearly parallel-margined, 

 roundingly narrowing to the clypeus where it is still very broad, 

 clypeus half longer than broad, sides parallel. Pronotum transversely 

 rugulose except a small area just behind the inside corner of the eye, 

 over twice wider than long, humeral margin long, side margin short 

 but distinct, anterior margin broadly and regularly curved, curve in- 

 cluding nearly one half the length of pronotum, scutellum large, tri- 

 angular, tip long, attenuate, partly concealed beneath the elytra. 

 Elytra broad, convex, scarcely narrowed before the broad apex, a little 

 longer than the abdomen. 



Color: Light gray, with a very variable amount of dark fuscous 

 markings. Vertex yellowish with a pair of large round spots slightly 

 farther from each other than from eyes, black, a median line and one 

 next each eye, dark reddish-brown. Face yellow v\ ith sutures, six or 

 seven short arcs on each side of the front, and a longitudinal line on 

 the clypeus, reddish brown. Pronotum light-gray with a series of 

 impressed points back of the anterior margin, a median line enclosing
