same lot as the two specimens Baker described. The 
Mexican specimens are paler and answer the Signoret 
description, except that there are four longitudinal stripes 
on the pronotum. One of the Arizona specimens has the 
median pair coalesced, which would give the three stripes 
of his description and figure.

Smaller than dohrnii , which it resembles in form; longer and 
narrower than gothica. Pale, with four divergent stripes on head 
and five parallel ones on pronotum; dark brown. Elytra, with a 
transverse white band before the apex. Length, 6 mm.; width, 
1 mm. 
Vertex, nearly flat, rather long, angled with a blunt point, the 
length and breadth at base equal; almost as long at pronotum. Pro- 
notum, broader than the eyes. Elytra, long and narrow; venation, 
obscure; two apical cells, sometimes three. Outline of .. face, as 
seen from side, almost straight, resembling bifida. 
Color; vertex, yellow, a black spot on the apex just below the 
margin; a stripe arising just outside and behind the apex on either 
side running back between the ocellus and the eye; a median dash 
some distance from apex, which abruptly terminates [in a pair 
of stripes, which run back parallel with the first pair, but inside the 
ocelli. Pronotum, with five stripes, the median one arising on the 
base of the vertex and continuing to the apex of scutellum; 
auother pair of stripes arising beneath the eyes and running back 
below the margin of the pronotum onto the elytra, where, together 
with the two pairs from the head, they break up into six stripes on 
each side, of which the outer pair furnishes three on the corium 
and the other two pairs the three on the clavus. These stripes are 
of a velvety brown, the outer pair darker anteriorly. The space 
between these stripes, the margins of the elytra, except the apical, 
some shade of yellow. Just before the apex of the elytra is a cres- 
cent-shaped, transverse band, which may be yellow or hyaline. 
Face and below, pale yellow; a few short fuscous arcs on the side of 
the front. Legs, pale. 
Genitalia; female segment scarcely twice the length of the pre- 
ceding; posterior margin obtusely rounding or almost truncate. 
Male ultimate segment very short; plates rather broad-triangular, 
their apices slightly produced; much exceeded by the pygofers. 
Specimens are at hand from Florida, Mississippi and 
Texas, where it is apparently common. It is also a com- 
mon Mexican insect. Specimens are at hand from many 
localities, bnt the two commoner forms are somewhat
