A new Chalcidid from an Oak Gall (Hym.). 
By T. D. A. CocKERELL, University of Colorado, 
Boulder, Colo. 
The beautiful Chalcidid here described was bred by Mr. 
E. R. Warren, the well-known Mammalogist, from galls of 
Holcaspis on an oak (Quercus undulata Torrey) at Trinidad, 
Colorado. The galls are like those of H. rubens, Gillette, but 
the single fly obtained seems different. 
Syntomaspis warreni n. sp. 
@.—Length (exclusive of ovipositor) 4 I-3 mm.; ovipositor 5 2-5 
mm.; wings ample, perfectly clear, venation pale fulvo-ferruginous ; 
head broad, peacock green, with faint crimson tints, frontal depressions 
behind antennae shining golden; eyes bright terra-cotta red; mandibles 
red except at apex; sides of face very minutely rugosopunctate, sides 
of front becoming striatulate; scape and ring-joint ferruginous; fla- 
gellum black, the joints very minutely longitudinally keeled; meso- 
thorax and scutellum with large thimble-like punctures, variegated 
with green and crimson, the posterior part of the scutellum minutely 
granular, with microscopical punctures, and with a marginal sulcus 
crossed by fine ridges; other parts of thorax variegated with green and 
purple; anterior coxae brilliant green; hind coxae very large, crim- 
son-purple; femora and tibiae bright chestnut red; tarsi cream color, 
rufescent subapically, black at apex; lower margin of hind femora 
minutely denticulate beyond the middle, but with no large tooth; abdo- 
men brilliant magenta, with blue-purple shades, first segment with a 
very large flap, which is strongly notched posteriorly; second segment 
carinate, deeply notched in middle; third segment also deeply notched; 
hind tibiae with two spurs; stigma sessile; ovipositor chestnut-red, its 
sheath black. 
Type in U. S. National Museum. 
Mr. J. C. Crawford has kindly compared this insect with 
the material in the National Museum, and writes that it comes 
very close to Syntomaspis californicus Ashm., which is green- 
ish or golden greenish, without the purple tints. The species 
is one of those which might be assigned either to Torymus or 
Syntomaspis.
