belong to this one, and it seems quite certain that all 

 records for hlerogliipliica from farther east than that, should 

 be referred to this species. Typical examples of similis 

 determined by Woodworth have been examined.

General form oPhieroghjpJi'ica 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 oil^othica. 



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 h, cres- 

 cent on either side anteriorly along the line of the frontal suture, 

 ProQotum 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,

 strongly angled, the apex formed by the convex keel. Male plates 

 long, t lender, 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 Powder 

 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
