less conspicuous. In the variety as well as in the species there is a variation in 

 the lengtli of the female genital segment, sometimes being very long and occa- 

 sionally rather short relatively, but always it is nearly or fully as long as rest of 

 abdomen. 



Described from one female eollceted at Banner, Wj'oming, by C. W. Metz, and 

 several from Pagosa Springs, Colorado (C. F. Baker). 



Aphalara pulchella n. sp. 

 (Figure 158, G, T; 159, N; 160, H) 



Length of body 2.0 mm.; length of forewing 2.6 mm.; greatest width 1.2 mm.; 

 length of vertex .29 mm.; width between eyes .46 mm.; witli eyes .72 mm. General 

 color black to glossy jet, occasionally brown. 



Head not deflexed, with eyes not as broad as thorax, very deeply and conspicu- 

 ously sculptured rugosol}' ; profile short. Occipital margin arcuate, slightly ele- 

 vated in center; postoccllar regions quite elevated; discal areas with a foveal im- 

 pression posteriorly ; anterior margin quite deeply emarginate or excised at median 

 suture and less so over antennal insertions. Facial cones wanting. Genae swollen. 

 Labrum rather small, subglobose, slightly pubescent. Antennal bases not swollen. 

 Eyes prominent. Anterior ocellus scarcely stalked, very slightly visible from 

 above. Antennae short. 



Thorax broad, nrch<-d, very conspicuously and coarsely sculptured rugosely, 

 more so than on head. Pronotuin moderately long, attaining laterad to central 

 axis of eye; pleuritcs short, depressed; pleural suture erect, arcuate; foreeoxae 

 mostly concealed. Dorsulum about twice as long as pronotum, areuately rounded 

 on botli margins, witliout posterior epiphyses. JVings relatively rather large, at- 

 tenuate basally, maculate more or less over entire surface, especially in distal 

 half; scarcely more tlian twice as long as broad, broadest across tip of second f ur- 

 eal, very broadly rounded at apex ; apex at or near tip of fourth furcal ; first mar- 

 ginal cell more than half as long as radial cell; second marginal cell large; cubital 

 petiole scarcely as long as diseoidal subeosta; pterostigma almost wanting. 



Male — Abdomen slender. Genital plate long; profile slender; dorsal margin 

 straight, elaspers large, elavate-spatulate, attenuate at base; anal valve large; 

 posterior lobe very long, tapering as long as genital plate; axial epiphysis quite 

 large, obtusely rounded ; pubescence sparse. 



Female — Abdomen stout, short. Genital segment very long, much longer than 

 rest of abdomen, slender, acute; dorsal plate longer and less acute than ventral 

 genit.il pore relatively short, witli n sliort fringe of hairs on inferior edge of dorsal 

 plate over ovi|)ositor; ))ubescence sparse. 



Described from one male and several females collected in Claremont, California, 

 and San INIateo county, California, by C. F. Baker.
