 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 o<" median line; genal cones nearly as long as vertex, rounded 

 at apex, slightly divergent. Forewings rounded at apex, conspicuously 

 spotted, pterostigma very small, short. 



cf . Anal valve longer than forceps, broad at base and tapering toward 

 apex somewhat. Forceps broader and shorter than in A, ceanothcr taper-

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. ceanothcr Crawford 

 (U. S. Nat. Mus. Bui. 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 Allot ria or Xystns] 

 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 I'liilcd 

 Slates National Museum, the following synopsis may imli-
