of hind tibia nearly one half as long as the metatarsus; claws of front and 

 middle tarsi with a long appendage at base. Wings hyaline, without cubital 

 or discoidal streaks ; stigma light brown, not very broad, the radial cell short, 

 its outer edge very oblique. 



Type from Tacoma, Wash., August 28, 191 1. Five other speci- 

 mens from Burton, Wash. ; Vashon, Wash. ; Pullman, Wash. ; and 

 Berkeley, Cal., taken during June and August. All were collected 

 and sent to me by Prof. A. L. Melander. 



This species is similar to the eastern E. quadriceps Ashm., which 

 it resembles very closely. It is at once separated by the absence of 

 striae on the ovipositor. From E. femdratus Ashm. it is easily dis- 

 tinguished as set forth in the key to species. 



Exallonyx fuscicornis new species. (Fig. 13.) 



<$. Length 3.5 mm. Black; tegulae, palpi, scape of antennae and legs 

 brownish yellow ; front and middle coxae light brown ; flagellum of antenna? 

 fuscous ; hind coxae black. Head barely twice as broad as long, strongly nar- 

 rowed behind ; ocelli in a flat triangle, the hind ones farther from one another 

 than from the eye-margin. Eyes removed from posterior margin of head by 

 their own width, bare or nearly so ; malar space as long as half the width of 

 the eye, without furrow ; head much narrowed below when seen from in front ; 

 margin of clypeus straight. Antennae reaching to basal third of second ab- 

 dominal segment; scape twice as long as thick; first flagellar joint simple, 

 without process, not quite three times as long as thick and subequal to the 

 second, third and fourth ; following slightly shorter, subequal, becoming more 

 slender; second to seventh joints each with a carina externally on the basal 

 half that forms a dentate process at the middle of the joint, those on the 

 second and seventh less prominent. Mesonotum polished, without trace of 

 parapsidal furrows ; depression at base of scutellum broad and rather deep 

 behind. Propodeum short, its horizontal face but little longer than the de- 

 clivity ; basally with an indistinct median carina, but with the basal smooth 

 space very short ; elsewhere rugose-reticulate. Propleura smooth. Meso- 

 pleura with a small striate area anteriorly near the base of the front coxa 

 and with the lower punctures near its hind margin prolonged into short striae ; 

 metapleura with a very small, smooth space above. Petiole of abdomen wider 

 than long, with a few coarse, irregular ridges above, coarsely striate below ; 

 basal striae on second segment coarse, of equal length, as long as the petiole. 

 Legs stout, longer spur of hind tibia slightly over one half the length of the 

 metatarsus ; front and middle tarsal claws with a long, slender appendage at 

 base. Wings hyaline tinged with brownish, cubital and discoidal veins very 

 finely indicated as brownish streaks; stigma moderately broad; radial cell very 

 short, the outer vein entering the costal margin at an angle of about 45 . 



One specimen from Woods Hole, Mass., collected by the writer 

 during July, 1902.
