ASHMEAD 



flagellum elongate, the first the longest, about seven times as long as 

 thick. Head closely, rugulosely punctate, the clypeus with a median 

 tooth anteriorly. Thorax smooth and shining but sparsely punctate, 

 the parapsidal furrows distinct anteriorly for more than half the length 

 of the mesonotum ; the metathorax has two transverse carinas and a 

 more or less complete areola, the lateral carinse of same being however 

 very delicate ; spiracles oval but not large. Wings hyaline, with a 

 small but distinct fuscous cloud beneath the stigma ; the disco-cubital 

 vein is broken by a long stump of a vein at its middle ; areolet pentag- 

 onal, narrowed above. The abdomen is longer than the head and 

 thorax united, the petiole being smooth, elbowed at its apical third and 

 with two dorsal carinas that extend a little beyond the spiracles ; dorsal 

 segments finely, closely punctulate or shagreened, the sculpture of seg- 

 ment 5 and beyond being finer and less distinct. 



Type. — Cat. No. 5610, U. S. Nat. Museum. From Sitka, June 16. 

 One specimen. 



Differs from the type species of Cryptoideus in having the apical 

 transverse carina complete, but agrees otherwise in all essential generic 

 characters. 



Subfamily PIMPLIN.^. 



Tribe LISSONOTINI. 



Genus Himertosoma Schmiedeknecht.^ 



HIMERTOSOMA SCHMIEDEKNECHTI sp. nov. 



Male. — Length 4.5 mm. Black ; face below the insertion of the 

 antennae, except a short median line at base, cheeks, mandibles, palpi, 

 tegulae, and the front and middle coxae and trochanters and the second

 and middle legs fulvous, the hind legs black. Wings hyaline, the 

 stigma and veins brownish-yellow, the venation similar to that in the 

 genus Lajnpro?tota except that the submedian cell is fully as long as the 

 median, or a little longer, the disco-cubital vein being curved, while the 

 transverse median nervure in the hind wings is broken far below the 

 middle. Abdomen polished black, except the petiole which is finely 

 wrinkled and bicarinate, the ventral fold more or less yellowish or 

 whitish.' 



'This genus and Bcthrodoca Schmiedeknecht, do not appear in my classifi- 

 cation of the Ichneumon Flies (Proc. U. S. Nat. Mus., xxni, 1890) ; they were 

 characterized after it was submitted for publication, vide Zool. Jahrb. Jena, Bd. 

 XIII, 1890, pp. 303, 306.
