THE JUMPING PLANT-LICE OR PSYLLID^ OF THE NEW WORLD. 121 



in September; nine from Los Angeles County, California (Koebele), 

 on Ceanothus rigidus, in May. These are labeled CepJialopsylla 

 rugipennis, Riley, a manuscript name. 



Type.— C&t. No. 18099, U. S. Nat. Mus. 



The California specimens are uniformly a little smaller, lighter in 

 color, and the forewings are a little less rugose. There seem to be 

 no structural differences, however. One specimen of the Arizona 

 lot is somewhat distinct in a few minor respects and seems to repre- 

 sent a varietal form of the species. 



EUPHALERUS RUGIPENNIS IMMACDLATUS, new variety. 



Similar to the species in most respects; body surface finely punc- 

 tate or very finely rugose, without white spots so characteristic of 

 the species; genal cones about half as long as vertex, less pubescent. 



Described from one female from Oracle, Arizona (Hubbard and 

 Schwarz) . 



EUPHALERUS VERMICULOSUS, new species. 

 Figs. 39, 41, 225, 434. 



Length of body 2.1 mm; length of forewing 2.4; width of head 0.98. 

 General color greenish white; thorax darker, with numerous irregular 

 brown spots. 



Head subvertical, not deflexed below level of pronotum, long, nar- 

 row laterally, very markedly vermiculo-punctate, fully as broad as 

 thorax; vertex flat, large, with a small but distinct fovea on each 

 side of median line posteriorly, sides straight between eyes, then 

 converging toward apex, truncate anteriorly; median line scarcely 

 impressed. Genal cones large, continuous at base, slightly divergent, 

 broadly rounded at apex, scarcely or not at all depressed below level 

 of vertex, separated from vertex by a slightly impressed line, pubes- 

 cence short. Antennae short, with a conspicuous protuberance at 

 base of insertion. Eyes large, recessive. 



Thorax strongly arched longitudinally and transversely, coarsely 

 punctate; pronotum vermiculo-punctate; prsescutum rugoso-punc- 

 tate. Pronotum long, broad, ascending; propleurites long, narrow, 

 largely concealed behind receding eyes; scutum long, well arched. 

 Hind tibiae with a small tooth at base. Wings relatively small, 

 subhyaline at base, fumate in apical third, often brown along 

 apical margin, about twdce as long as broad, very broadly rounded 

 at apex, slightly rhomboidal; apical marginal vein often alternately 

 white and black; marginal cells subequal; radial sector long, curved; 

 pterostigma short, yellowdsh; claval suture prominent. 



Oenitalia. — Male. — Genital segment rather large; forceps slender, 

 long, with a black, hook-Hke process at apex, pubescent; anal valve, 

 large, long, broad, simple, truncate at apex, pubescent. Female. — 

 Genital segment as in preceding species.
