Maryland and Illinois south to Florida and Texas, and on 

 throutjjh Mexico to South America. 



Ileadily separated from bifida by the much smaller size 

 and the green elytra with the three white spots before the 

 smoky apex. Some Florida males are almost black, and 

 might be confused with hartii males, if they were not so 

 much more slender than that species.

Resembling b/p'da in form and structure, smaller, and 

 with a longer head. White, with the nervures and three 

 spots on vertex, black. Length, 5 mm. 



Vertex long, conical !y pointed, almost as long as the pronotum. 

 Pronotum as wide as the eyes at the lateral angles, narrowed in 

 front. Elytra inclined to be flaring, venation simple, no cross nerv- 

 ures between the sectors, the second fork of the tirst sector occur- 

 ring beyond the middle of the outer branch, the two veins often 

 scarcely separated. Face, as seen from side, gently curved, very 

 deep. 



Color; white, vertex with a spot on the apex, and circles around 

 the ocelli black, a few brown arcs on the reflexed portion of front 

 and often a brown point on the middle of the disc. Front with 

 very short brown arcs, the ends of which are enlarged and form four 

 longitudinal lines, the two on either side uniting just before the 

 clypeus and extending below the middle of that piece where they 

 unite. Pronotum with the margins very narrowly lined with brown, 

 two transverse bands on the disc, one parallel with each margin, 

 equidistant on the median line, the posterior one abbreviated. 

 Scutellum with an abbreviated median brown line. Elytra with 

 the margins, nervures and claval suture narrowly lined with brown, 

 paler at the apex. Legs and below pale. 



Genitalia; female segment nearly twice the length of the preced- 

 ing, slightly rounding or truncate posteriorly. Male plates broad 

 at base, obtusely triangular, their apices produced into attenuate 

 points; the whole scarcely as long as the large ultimate segment. 



Specimens are at hand from Maryland, District of 

 Columbia, New Hampshire, New York, Oliio and Mexico, 

 and it has been reported from Canada, Illinois, Mississippi 

 and Missouri. 



The Mexican specimens have the vertex much broader 

 and blunter, as in the Mexican form ofwi/ida, and the spot 

 on the center of the disc is distinct and black. Fowler in
