122 BULLETIN 85, UNITED STATES NATIONAL MUSEUM. 



Described from one male from Claremont, California (C. F. Baker), 

 one male from Eureka, California (H. S. Barber), on Ceanothus sp., 

 in May, and numerous males and females from Placer County, Cali- 

 fornia (Koebele), on Ceanothus cordulatus, in September, and in 

 Siskiyou County, California. These are labeled in the National 

 Museum collection Cephalopsylla ceanothi Riley (MS). 



Type in author's collection. 



EUPHALERUS PROPINQUUS, new species. 



Figs. 131, 400. 



Closely related to vermiculosus, but readily separated on the follow- 

 ing characters: Head relatively broader; vertex much broader, more 

 deeply vermiculo-punctate, without brown spots. Genal cones 

 shorter, much broader, broadly rounded at apex, with apical portion 

 turned outward a little. Wings somewhat rhomboidal, usually with a 

 brown to black marginal band apically, more or less interrupted; 

 venation similar, except Cu^ distinctly shorter. 



Genitalia.— Male. — Forceps stout, abruptly narrowed apically into 

 a long, slender, hook-hke process, longer than in vermiculosus, acute 

 at tip and directed inward. Anal valve more rounded at apex, 

 stouter. 



Described from 13 males and females from Arizona, some of them 

 from the Chiricahua Mountains, collected by H. G. Hubbard in Sep- 

 tember, on Ceanothus. These bear the label in the National Museum 

 collection, Cephalopsylla latifrons Riley MS.

Genus ARYTAINA Forster. 



Arytaina Fokster '48: 69. 



Arytaena Scott '76: 528.— LoEW '78: 596. 



Psyllopa Crawford (n. n.) 'lie: 628; '12b. 



ResembUng Psylla in many respects and sometimes difficult to 

 distinguish therefrom; differing chiefly as follows: Genal cones 

 usually short and very broadly rounded, seldom long and acute as in 

 Psylla, extending parallel to plane of vertex but depressed below 

 it, not widely divergent; pleurites of pronotum (see fig. 1) subequal 

 in length, with pleural suture as in Aphalara. Wings usually more 

 narrowly rounded at apex, often more or less maculated, spotted or 

 marked, often less hyaline than in Psylla, but sometimes very similar 

 to wings of Psylla. In other respects not differing markedly from 

 Psylla in characters of antennae, thorax except propleurites as noted 

 above, legs including claw-like spines of basal tarsus of hind legs; 

 basal spur of hind tibise seldom distinct, if present. 



Type of genus. — Arytaina genistas Latreille. This is the first species 

 named in this genus by Forster and should be recognized as the type-
