belong to this one, and it seems quite certain that all 
records for hierogli/phica from farther east than that, should 
be referred to this species. Typical examples of similis 
determined by Woodworth have been examined.

General form of hieroglyphica somewhat narrower, ver- 
tex and pronotum each with about five black spots. Pos- 
terior half of pronotum and elytra blue. Length, 6 — 7 mm.; 
width, 1.25 mm. 
Vertex bluntly rounded, slightly narrowed at the eyes, two- 
thirds the length of the pronotum. Face, as seen from side, similar 
to gothica, clypeus slightly prominent, elytral venation similar to 
that of gothica. 
Color; head pale yellow, sometimes washed with pale blue, a black 
spot at the apex, surrounded by a pale circle. Front with a stripe 
either side of the middle, the lateral margin and the clypeal suture 
black, the two stripes are often effaced in the middle, leaving only 
a dash at the ends, clypeus with a black dash, vertex with a spot on 
the middle, a dash against each ocellus on the outside, and a cres- 
cent on either side anteriorly along the line of the frontal suture. 
Pronotum with the anterior half pale, broadest behind the eyes, a 
black spot behind the outer corner of either eye, a pair just inside 
the eyes on the sub-margin, and three dots between these latter. 
Posterior half bright blue, with a large, transverse spot behind the 
middle on either side, and a small dot or longitudinal spot between 
them. Elytra bright blue, the nervures narrowly black. Legs, 
orange. 
Genitalia; female segment three times the length of the preced- 
ing, the median line elevated into a strong keel, posterior margin 
strongly augled, the apex formed by the convex keel. Male plates 
long, slender, style-like, about three times the length of the ulti- 
mate segment, the margins with fine hairs. 
Numerous specimens are at hand from Arizona and 
California. It is reported as being one of the most abun- 
dant and injurious Jassids in southern California. . 
Signoret described this species from Brazil, and Fowler 
has it (figured) from Mexico. Neither author’s figures are 
very good for the insect as it occurs in our territory, but 
Signoret’s description, which is very full and complete, and 
includes face markings and genitalia, both very striking 
and distinctive, leaves no doubt as to this being the species
