66 HYMENOPTERA. 



hairs on wings and marks on pleurse, fuscous. Dimensions (c = 0.0333 

 mm.): Entire length 19c. ; length of head 3 c, thorax 7c, abdomen 

 lie, antennae 4 c (measured alive, hence not consistent), width of 

 head 5c, thorax 5c, abdomen 5c. See drawings by Hyslop. 



The rows of yellow eggs are inserted between the sheath and its own 

 inner epithelium and each egg is enclosed in a delicate glue-like case 

 which adheres to the epithelium. The eggs are imprinted with the 

 striae of the stem where they rest against it. Color pale yellowish- 

 brown. No micropylar structures. Length 0.97 mm., width 0.21 mm. 



Jan. 6, 1910. — Hyslop writes from Washington that the alcoholic and 

 balsam specimens which he took to Washington have been turned 

 over, with those of the National Museum, to Mr. Girault." 



4. Westvvoodelhi coiuosipeuiiis species nova. 



Normal position. 



Female. — Length, 0.75 mm. 



This species is closely related to both americana and sub- 

 fasciatipennis in having the greatest width of the fore wings 

 distinctly greater than the length of the longest marginal 

 cilia of the fore wing, in having the general shape of the 

 fore wings similar and in habitus but differs from both in its 

 distinct discal ciliation, the discal cilia longer, moderately 

 dense, conspicuous ; besides this the fore wings are uni- 

 formly and somewhat more noticeably clouded throughout 

 and there is a slight stigmal fuscous dash (as in the others) 

 which is dart-shaped, giving the knob of the stigmal vein an 

 acute, spine-like prolongation apparently ; this stigmal spot 

 points more caudad, less proximad, than that in the other two 

 species and the stigmal uncus is decidedly stronger, point- 

 ing directly distad. There are still other differances, for in- 

 stance the proximal club joint being longer than wide and 

 the caudal tarsal joints distinctly slenderer. 



General color deep-orange yellow, the legs yellowish-brown except- 

 ing the distal tarsal joint and the lateral aspect of the caudal coxae and 

 femora which are dusky black ; eyes dark garnet. Antennae and the 

 venation concolorous with the legs. Caudal tarsal joints slender, the 

 proximal longest, nearly twice the length of the distal joint, the inter- 

 mediate joint also long and slender, a fourth shorter than the proximal 

 joint which is about ten or more times longer than wide. Intermediate 

 tarsal joint of the caudal legs distinctly longer and slenderer than the 

 distal joint. Otherwise as in america^ia. (Mandibles with at least two 

 distinct teeth.) 



Male. — Unknown.
