Maryland and Illinois south to Florida and Texas, and on 
through Mexico to South America. 
Readily 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 bifida 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, conically 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 wiih 
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, Ohio 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 of bifida , and the spot 
on the center of the disc is distinct and black. Fowler in
