ACRASPIS GUADALOUPENSIS (Fullaway) 



Callirhytis guadaloupcnsis Fullaway, Ann. Eut. Soc. Anier., vol. 4, 1911, p. 

 363, pi. 23, fig. 4. 



Because of the rudimentary Avinj^s and the structure of the ventral 

 spine this species is here transferred to Acraspis, althou.<>:h the wino's 

 are not reduced so much as in the eastern species of the genus, the 

 mesonotum consequently beini^ more robust, broader, and not so 

 pointed behind. The fjalls are of a different type from those of the 

 eastern species. The thin round disk-shaped galls are widely dis- 

 tributed in California on Q. chivj sole pis. The writer has collected 

 them at Idyllwild, in the San Bernardino, San Gabriel, and Santa 

 Lucia Ranges, on Mount Diablo, in California Redwood Park, in 

 Sequoia National Park, at Los Gatos, Calistoga, Ukiah, Shasta, 

 Baird and Scott Bar, and at Canyonville, Oreg. The date of 

 emergence is unknown but from galls collected in late September, 

 living flies were cut out November 9. 



What seem to be the same galls were collected on Q. wilcoxii in 

 the Santa Catalina Mountains in Arizona.
