turn ratio is 1.1, antenna 2.7, ovipositor 2.8, wing 2.3. Length 2.0-2.6 

 mm. Average of 5 specimens 2.3 mm. 



Type.— Cat. No. 27203, U.S.N.M. Type and one paratype. Para- 

 types at American Museum, Field, and Stanford. 



Host. — Querelas ckrysolepis. 



Gall (fig. 42). — Somewhat wedge-shaped, hanging singly or in 

 small numbers from the under surface of the leaf in the fall. The 

 galls measure up to 10 mm. long by 5 mm. wide by 3 mm. thick, 

 concave on the two broad sides, deeply grooved around the edge, 

 nearly the color of the leaf, the flanges often reddish. The larval 

 cavity is placed transversely at the apex of the gall and from it a 

 long cavity runs up the center of the gall toward the ]:>edicel. 



Habitat. — The type material was collected September 21, 1922, 

 near Idyllwild, Calif., on the slopes of Taquitz peak in the San 

 Jacinto Mountains. Living adults were cut out of the galls on 

 November 11. 



ACRASPIS PATELLOIDES, new species 



Agamic female. — Head and thorax yellowish-brown, antennae, 

 tibiae and tarsi, median region of head from ocelli to clypeus, be- 

 tween anterior lines and disk of scutellum darker, abdomen reddish- 

 brown to black. Head and thorax with dense appressed pubescence. 

 Head granulate, broader than thorax, cheeks broadened behind 

 eyes, occiput concave, malar space one-half q,\q without groove, 

 antenna 14 segmented, lengths as (scape) 14 : 6 : 18 : 16 : 13 : 12 : 11 : 

 10 : 9 : 8 : 7 : 6 : 6 : 12. Mesoscutum broader than long, covered with 

 setigerous punctures, parapsidal grooves incomplete. Disk of scutel- 

 lum finely rugose, sloping and slightly pointed behind, an indistinct 

 arcuate groove at base without pits. Carinae on propodeum arcuate 

 but weak. Tarsal claws with a strong tooth. Wing reduced, reach- 

 ing about to tip of abdomen, subhj^aline, pubescent, ciliate, veins 

 brown, second abscissa of radius faint, no areolet. Abdomen longer 

 than head and thorax, length to height to width as 32 : 25 : 16. lengths 

 of tergites along dorsal margin (knife-edged back of second) as 

 56 : 20 : 17 : 9 : 4 : 14, second pubescent on sides, exposed parts of ter- 

 gites 3-6 aciculate ventrally, tuft of hair on sheath over ventral 

 valves, ventral spine short, broad, rounded at end, bristly. Using 

 width of head as a base the length of meson otum ratio is 1.2, antenna 



2.6, ovipositor 2.6, wing 2.7. Lengths of four pinned specimens 



2.7, 2.75, 2.0, and 2.95 mm. 



Type.— Cat. No. 27204, U.S.N.M. Paratypes in Field and Stand- 

 ford museums. 

 Host. — Quercus chrysolepis.
