cones and pronotum dirty white; dorsum of thorax with pale streaks and 
spots; in the lighter forms the dorsum is light with darker streaks and 
spots; antennae pale on basal portion, remainder dark; forewings whitish, 
with brown spots scattered over surface. 
Head not strongly deflexed; vertex with a foveal impression discally 
on each side of median line; genal cones nearly as long as vertex, rounded 
at apex, slightly divergent. Forewings rounded at apes, conspicuously 
spotted, pterostigma very small, short. 
o&.—Anal valve longer than forceps, broad at base and tapering toward 
apex somewhat. Forceps broader and shorter than in A. ceanothe taper- 
ing gradually to a blunt point at apex. @.—Genital segment not as 
long as rest of abdomen, thick at base and tapering to acute apex and 
slightly upcurved. 
Described from four males and four females all collected 
at Fallen Leaf Lake, El Dorado County, California, Aug-

Holotype, male (No. 464), in collection of the California 
Academy of Sciences. 
Of the species previously described, A. ceanothe Crawford 
(U.S. Nat. Mus. Bul. 85, p. 130) appears to be most closely 
similar in structure and appearance, except that in the species 
referred to the wings are perfectly clear. 
A New Parasitic Cynipid Reared from a Clover 
Aphid (Hym.). 
By L. H. WELD, Bureau of Entomology, U.S. Department of 
Agriculture. 
Through Mr. H. L. Viereck of the Biological Survey there 
came into my hands recently for examination a series of 
parasitic Cynipidae reared from a clover aphid at Twin 
Falls, Idaho, by Mr. Ralph H. Smith. The species runs 
to the genus Charips (formerly known as Allotria or X ystus) 
and seems to be new. An examination of the literature shows 
that only eight American species of this genus have been 
described, one in the subgenus Bothrioxysta and the rest in 
the typical subgenus. From the published descriptions and 
from a study of the types of four of the species in the United 
States National Museum, the following synopsis may indi-
