OF WASHINGTON. 295 



mandibles and palpi pale ferruginous; antennae long, black, the basal two 

 joints ferruginous, the first being sub-globose and obliquely truncate at 

 apex. Thorax black, sculptured and pubescent like the head ; mesonotal 

 furrows only slightly indicated anteriorly; scutellum smoother than the 

 surrounding surface, shining, in marked contrast to the mesonotum, 

 with a transverse fovea at base ; the long, lateral fovese of the postscutel- 

 lum crenate or striate at bottom ; metathorax distinctly areolated, the cen 

 tral or middle area hexagonal ; the surface of the petiolar area and the 

 lateral area transversely rugulose ; spiracles small, oval ; mesopleura with 

 a series of ridges below tegula and smooth toward the posterior margin, 

 shining, with a deep fovea at the middle; wings hyaline; tegulae and a 

 spot at the base of the stigma whitish, the nervures ferruginous, the stigma 

 fuscous, third discoidal cell more than twice the length of the second, the 

 discoidal nervure simple, not broken by a stump of a cubital nervure; 

 transverse median nervure in hind wings broken very near the base; legs 

 rufous. Abdomen, with the petiole black except toward posterior border, 

 the spiracles placed behind the middle; the other joints rufous, smooth, 

 impunctate; joint 2 one-half longer than 3. 

 Hab. Salem, Mass. 



Described from a single male specimen reared April 19, 1872, 

 by J. H. Emerton, from a cocoon of Prosthesima furcata. 



This species comes nearest to H. townsendi Ashm. in size and 

 color, but is different in sculpture and in the venation of hind 

 wing. The surface of H. toivnsendiis smooth, shining, sparsely 

 punctate, the transverse median vein in hind wing being broken 

 a little below the middle, while in H. prosthesimce the surface is 

 closely, densely granulate, the transverse median nervure in hind 

 wing being broken very close to the base. 



18. Hemiteles micarivora Riley sp. n. 



Male. Length, 4 mm. Head black, opaque, densely, closely granulate, 

 with a few large sparse punctations, and with a fine, short pubescence ; 

 the clypeus distinctly separated and sculptured as the face ; mandibles 

 rufous; antennae as in H. prosthesimce ; also the scutellum and the meta 

 thorax, except that the surface of all the areas is rugulose and the dor- 

 sulum of postscutellum is striate. Thorax colored and sculptured like the 

 head ; wings with the venation darker than in prosthesimce, although the 

 tegulae and a spot at the base of stigma are white ; third discoidal cell only 

 about twice as long as the second ; discoidal nervure broken by a stump 

 of a cubital nervure ; legs obscure rufous, the tarsi slightly fuscous, as also 

 the knee and terminal part of tibiae in hind pair. Abdomen smooth, rufous, 

 posterior part of fourth and all of following joints black; joint 2 not 

 quite one-half longer than 3 ; petiole faintly striate, the spiracles near an- 

 tei'ior third.
