punctate, lobes of the mesoscutum and the scutellum polished, with 

 separated punctures, notauli deep and extending well back, where 

 they end in a depressed area, which with the notauli is heavily sculp- 

 tured; sternauli entirely absent; a small highly polished area in 

 upper hind corner of mesopleurum; propodeum transversely rugu- 

 loso-punctate, less strongly so in front of the transverse carina, 

 spiracle oval, midway between base and carina; abdomen elongate 

 fusiform, subpolished, with fine scattered punctures; first tergite 

 barely half as wide at apex as long, with a median longitudinal im- 

 pression, spiracles at the middle; exserted portion of ovipositor 

 about half as long as abdomen ; legs slender. 



Black; with abdomen and legs largely red; a nearly complete 

 orbital ring, basal transverse mark on clypeus, a minute spot at base 

 of each mandible, dorsal margin of pronotum, tegulae at base, post- 

 scutellum, and minute mark on each side of posterior face of propo- 

 deum, pale yellowish ; palpi piceous ; antennae black with yellowish 

 annulus embracing flagellar joints 8 to 9; coxae and basal joints of 

 all trochanters black, legs otherwise reddish testaceous, the hind 

 tibiae and tarsi somewhat darkened; wings hyaline, faintly brown- 

 ish, veins and stigma blackish, their bases together with the apices 

 of the tegulae brown; abdomen rufous with the lateral margins of 

 tergites 2-5 and apices of 3-5 blackish; sheath of ovipositor black. 



A female paratype is essentially like the type but lacks the black- 

 ish color of the abdomen and the pale markings of the head are less 

 conspicuous. 



Male. — Differs from female principally as follows; abdomen slen- 

 der and subparallel-sided; first tergite narrower with longitudinal 

 impression weak or absent; spots on mandible, postscutellum, and 

 propodeum lacking; antennae not annulated; hind tibiae infuscate, 

 tarsi black with third and fourth joints wdiite; abdomen in allotype 

 entirely red, in paratype male black at apex.

Type.—Q?it. No. 21636, U.S.N.M. 



Described from the above two females, reared under United States 

 Department of Agriculture, Bureau of Entomology, No. 6184°, April 

 10 and 2, 1894, respectively, from the former host in apple, and two 

 males from Los Gatos, California, reared by H. E. Burke under 

 Hopkins U. S. Nos. 14:505a2x and 14653a- parasitic on Agrilus angel- 

 icus in Quercus agrifol'ia. 



Strikingly Cryptine in general appearance this species has, never- 

 theless, a strong resemblance to the species of the genus Tlelcostizus^ 

 although agreeing with Cryptoideus in most of the characters that 

 separate those two genera.
