THE JUMPING PLANT-LICE OK PSYLLID^ OF THE NEW WOELD. 131 



not much longer than forceps, roundly tapermg to tip, subacute at 

 apex. Female. — Genital segment almost as long as rest of abdomen, 

 broad at base, acuminate, very acute at apex; dorsal valve some- 

 what longer than ventral, equally acute. 



Described from many males and females collected at Claremont, 

 California, by D. L. Crawford, on Ceanothus crassifolius; found in 

 very great numbers and in all stages of development in the middle 

 of April; three from Los Angeles, California (Coquillett), April, 

 on the same host plant; twenty-two from Santa Clara County, Cali- 

 fornia (Koebele), May, on Ceanothus rigidus; eight from Eureka, 

 California (H. S. Barber), May, on Ceanothus, and one from Scotia, 

 California (Barber), May; several from Claremont, California, on 

 Rhamnus sp. 



Type in author's collection. 



ARYTAINA ACULEATA, new species. 



Similar to ainorphse and ceanothae in size and general appearance, 

 with whitish thoracic markings as in the former, and head as in the 

 latter; differing from both in female genital segment, which is sub- 

 globose at base and produced caudad into a slender, black, styliform 

 process not as long as the large basal portion. Wings as in amorphse, 

 but first marginal cell much shorter and pterostigma much smaller. 



Described from three females from California, two of them from 

 Santa Cruz Mountains (Koebele), and the other from Los Angeles 

 (CoquiUet), no data accompanying either, but the latter specimen 

 was placed with several specimens of ceanothse collected on Ceanothus 

 crassifolius, April 1 , in the same locality.
