76 EDWARD NORTON. 



five out of forty-nine females of his P. grossularise traces of a first 

 submarginal cross vein could be discovered. 



1. P. sycophanta. 



Pristiphora sr/copJianta, Walsh, Proc. Ent. Soc, Phil., vi., 1866, 263, % . 

 Length, % , 0.16 in. Br. wings 0..32 in. 



"S . Black. Head polished, but sparsely and rather coarsely punc- 

 tate. Face with a lofty, but obtuse carina extending from between the 

 antennae to the clypeal suture. Clypeus squarely truncate. Labrum 

 twice as wide as long. Mouth entirely black. Antcnnse nearly as long 

 as the body, black above, brown-black beneath, joints 8 — 5 sub-equal, 

 f) — 9 very slowly shorter and shorter. Thorax polished, with fine shal- 

 low punctures. Teguh"e and cenchri dull yellowish. Ahdomeu polished, 

 with fine shallow punctures, sparse towards the base. Legs whitish; 

 cox^e, except their extreme tips, femora, tarsal tips and in the hind legs 

 the terminal one-eighth of the tibiae and of theentire torsi, all black. 

 Wings hyaline ; veins black, costa and stigma dusky, first submargi- 

 nal cross vein obsrlete, the ante-peuultial cell receiving both veins in 

 the normal manner. 



Rock Island, 111. 



OneS , Inquiline. Bred August 9, from a cocoon found July 27, 

 inside the Cecidomyidous gall, Salix brassicoides, Walsh, of the same 

 years growth. The following is probably the same species. 



2. Pristiphora tibialis, n. sp. 



Shining black, legs white, with black banded femora; wings hyaline. 

 Length 0.22. Br. wings 0.46 in. 



9 Black. Antennpe black, about half the length of the body, third 

 joint a little longer than fourth. Head closely punctured; channels 

 at sides of ocelli almost obsolete; the ridge between antennae channeled 

 through the middle ; nasus moderately notched ; labrum piceous ; teg- 

 ulse reddish-white. Legs white; basal two-thirds of coxtB, a wide band 

 on the femora and apical third of posterior tibiae black ; tarsi black- 

 ish, basal joint white ; tibial spurs all sharp, pilose; claws with a short 

 inner tooth. Wings hyaline, nervures blackish, stigma full. 



% . Antenna3 longer, slender; nasus hardly incurved, labrum white ; 

 the white and black on legs very clearly defined. 



Ct. Md. (Mr. Uhler.) Pa. (Smith's Inst.) Va. and 111. (Am. 

 Ent. Soc.,) Phil. 



The body is short and stout, as in Sdandrla. It seems most proba- 

 ble that this is identical with F. sijcopkanta, of Mr. Walsh, although 

 diiferiu"' in form of antennas.
