Cynips (Acraspis) conica, new species
agamic form

GALL. — A smooth, pointed, conical leaf gall with the broadened base bearing spiny projections. Regularly or irregularly conical, up to 7.0 mm. in height; or the tip rather sharply pointed (and sometimes curved) ; the base sometimes flaring, its edge entire or bearing up to 6 short, blunt, spiny projections; the base up to 6.0 mm. in diameter; entirely smooth and glossy, or in part finely puberulent, light pinkish brown, with a violet tinge due to the puberulence. Internally filled with a rather compact mass of branched fibers, the larval cell rounded, up to 2.5 mm. in diameter, located very near the base of the gall. Attached by a slightly projecting point on the middle of the broad base, on the veins of the under surfaces of leaves of Quercus grisea. Figures 288- 289, 336.

RANGE — Arizona : Globe. Probably confined to a limited area including the country between Globe and Phoenix, Arizona. Figure 57.

When the type material was collected at Globe on January 20 (in 1920), most of the galls showed the holes thru which the adult gall makers had previously emerged ; but three adults emerged a few days after that. Emergence thus occurs in mid-January, even tho the winter season is rather severe in the mountains near Globe. No further life-history data are available, but judging from the related species of the genus, the gall may be expected to appear early in the summer. Other varieties of conica may be expected in Arizona, New Mexico, and West Texas, and further south in Mexico.
