same lot as the two specimens Baker described. The 

 Mexican specimens are paler and answer the Signoret 

 description, except that there are fonr longitudinal stripes 

 on the pronotum. One of the Arizona specimens has the 

 median pair coalesced, w^hich would give the three stripes 

 of his description and figure.

Smaller tha,n dokrfni, which it resembles in form; longer and 

 narrower then^g-oi/iu-a. 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 flit, 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 th^ee. 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 tive stripes, the median one arising on the 

 base of the vertex and continuing to the apex of scutellum; 

 another 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, but the two commoner forms are somewhat
