to the Northeast, seem to indicate that they may be distinct species 

 but closely related. 



The characters of the male genitalia have been taken from Miss 

 Patch's description, since only female specimens are before me. This 

 description has been based on four females, two from Bretton Woods, 

 New Hampshire (van Duzee), June 30, 1909; and two from Massa- 

 chusetts (PhUip Uliler), bearing Harris's manuscript name of PsyUa 

 pallida. Miss Patch gives as localities: Ottawa, Ontario, Canada, 

 and Tompkins County, New York. 



APHALARA ALASKENSIS Ashmead. 



Figs. 109, 111, 112, 132, 403. 



Jphalara alaskensis Ashmead '10:136. 



Length of body (male) 2.1 mm; length of forewuig 3; width of head 

 0.78. General color dark brown to black, sometimes flavous (per- 

 haps immature adults); vertex glossy black, smooth; thoracic dorsum 

 mostly black, strigate; pronotum yellow on hind margin; pleurae 

 around wing bases and connexiva of abdominal segments flavous; 

 tibiae, basal tarsus, antennae except tip, yellow; wings maculated 

 brown, picture as in figure. In the two paratypes of this species 

 from Fox Point, Alaska, the color is nearly uniformly flavous with 

 indications of brownish markings, and the wings are indistinctly 

 maculated, as described above. It is possible that the darker indi- 

 viduals represent a varietal form of the species, but it seems most 

 probable that the Alaskan individuals were not yet fully colored. 



Head large, fully as broad as thorax, scarcely deflexed; vertex 

 very broad, smooth, glossy, broadly depressed discally on each side 

 of median line, less emarginate over front ocellus than in pulcJiella; 

 gense and clypeus small; eyes very large and prominent. Antennae 

 very long relatively, nearly twice as long as width of head, slender. 



Thorax long, somewhat arched, strigate on dorsum. Legs long, 

 slender, especially the front pair. Wings hyaline, transparent 

 except on the maculae, nearly two and a half times as long as broad, 

 broadly rounded at apex; marginal cells large, subequal. 



Genitalia. — Male. — Genitalia large; forceps large, bUobate, pubes- 

 cent; basal portion short and narrow, dividing into two long pro- 

 cesses; posterior process long, arcuate, acuminate, subacute at tip: 

 anterior process shorter, narrower, less acute, extending inward. 

 Anal valve long, with posterior lobes long and rather large. 



Described from six males, two from Fox Point, Alaska (paratypes), 

 July, 1899, collected by Harriman- Alaska Expedition; one from 

 Easton, Washington (Koebele) ; and three from Colorado (C. P. Gil- 

 lette), no data.
