Aug., 1915, the other two from Tacoma, Wash., Aug. 28, 191 1. All 

 were collected and sent me by Prof. A. L. Melander. 



This species is very similar to the eastern C. flavipes Prov. in 

 wing venation and length of the tibial spur. It differs most strik- 

 ingly in the form of the head which is narrowed and lengthened be- 

 low the eyes, making the malar space longer. 



Cryptoserphus melanderi new species. (Fig. 8.) 



(§. Length 3 mm. Black, highly polished ; legs beyond the trochanters 

 yellow-brown. Head twice as wide as long when seen from above ; face 

 strongly convex medially, but without a vertical ridge-like protuberance below 

 the antenna- ; clypeal foveas much more deeply impressed than usual, forming 

 deep pits ; clypeus short and broad, with nearly straight lower margin, bulg- 

 ing below the foveas. Malar space short, with a finely impressed furrow as 

 long as the width of the mandible at base; front with a vertical impression 

 between the base of the antennae and eye. Antennae rather stout, conspicu- 

 ously whitish pubescent. Scape very thick, one half longer than wide; first 

 flagellar joint about four times as long as thick at apex; second a little shorter 

 and stouter; third and following scarcely shorter, but becoming appreciably 

 more slender. Eyes very sparsely pubescent. Pronotum transversely striate 

 before the constriction ; behind with the lateral angle produced as a con- 

 spicuous, almost acute tubercle. Mesonotum with the parapsidal furrows im- 

 pressed close to the anterior margin, entirely absent elsewhere. Depression 

 at base of scutellum deeply foveate at each side. Upper face of propodeum 

 with two smooth areas dorsally, these narrowed behind owing to the oblique 

 lateral carinas ; outside of these with a transversely rugose oblong area behind 

 each spiracle; posterior surface somewhat concave and constricted, coarsely 

 reticulate. Pro- and mesopleurae smooth, the latter with a line of coarse 

 punctures inside its posterior margin; metapleura reticulate, smooth in front 

 above. Abdominal petiole not visible from above ; base of second segment 

 above with numerous, fine, parallel grooves nearly as long as the posterior 

 trochanter. Wings hyaline, stigma and veins brown ; stigma broad, trian- 

 gular; radial cell along the costa two thirds as long as the stigma; second 

 section of radius prolonged obliquely downward as a brown streak, cubital 

 and discoidal veins indicated by barely visible brownish streaks. Legs rather 

 stout ; longer spur of hind tibia as long as the metatarsus. 



Three specimens from Pullman, Wash., May 18, 1909, collected 

 and sent me by my friend Prof. A. L. Melander, for whom the spe- 

 cies is named. 



This is a very distinct species, recognizable by the deep clypeal 

 foveae, stout, evenly jointed antennae, sharply tuberculate prothorax 

 and rather long radial cell.
