fuscated), and trochanters 3;-fz<^«/j//. Wings hyaline, somewhat iridescent; venation 

 brown, basal half or third of stigma subpallid. 



Male. — Length 3.75 mm. ; length of anterior wing 4 mm. Robust. In gen- 

 eral much like the female, but differs as follows : Antennae longer ; walls of occllar 

 basin sharply defined ; interocellar furrow placed near occiput and stronger; lateral 

 ocellar furrows distinct to occiput ; head more distinctly punctured ; stigma broader 

 and rounded on the lower margin. Procidentia rather small, truncate at apex. Hy- 

 popygium obtusely rounded at apex, rather large. 



Habitat. — k ^ and $, Tolland, Colo., alt. 8889 ft., June 7, 

 1908 (S. A. Rohwer). Swept from .Stf/zlv sp. A very distinct species.

16. Cryptocampus propinquus, new species. 



Enura orbitalis Ckll., The Southwest, Vol. 2, 5 March, 1 900, p. 1 13. 



Male. — Length 5 mm. ; length of anterior wing 4.5 mm. Head seen from the 

 side rounded in front. Clypeus very shallowly emarginale ; lobes low and broad. 

 Antennal fovere large, deep. Middle fovea distinct, elongate, open at the top. Ocel- 

 lar basin with low but sharply defined walls. Interocellar furrow distinct ; lateral 

 ocellar furrows deep, distinct from occiput to antennal foveae. Antennae wanting in 

 the type. Head closely and rather coarsely granular. Dorsulum not as coarsely sculp- 

 tured as head, apparently punctured ; furrow of middle lobe of mesonotum distinct 

 for half the length of the dorsulum. Claws not very deeply cleft ; teeth subequal. 

 Venation normal. Stigma a little wider at base, gently tapering to the apex. Proci- 

 dentia rather broad, rounded at angles, truncate across apex. Hypopygium rather 

 sharper at the apex than usual. Black : lower margin of clypeus, labrum, mandibles, 

 (apices piceous), lower inner orbits, middle carina, superior and upper posterior 

 orbits, spot on angle of pronotum, tegulae, legs below coxae (apex of posterior tibiae 

 and their tarsi infuscated), apical part of venter of abdomen, bright reddish-yellmv. 

 Wings hyaline, iridescent, venation brown, including the stigma. 



Habitat. — Near Las Vegas, N. M. (Mary Cooper). " Sa/ix 

 gall 61." 



Ga// an enlargement of twig, abruptly so at base. The gall before 

 me contained two insects and is not evenly developed on both sides. 

 It reminds me of the abnormal gall of C. bebbiance Roh. It is on Salix 

 sp. (The bark when dry is brownish-red.) If this gall is an abnor- 

 mal one and as a rule is an abrupt, lateral, elongate swelling, the species 

 is most closely related to bebbianx Roh., from which it may be sepa- 

 rated by the foregoing table. If the gall is normal it is related most 

 closely to viacgilli-vrayi ^o\\., from which it maybe known by the 

 dark stigma, the deep lateral ocellar furrows, the more shallowly emar- 

 ginated clypeus, etc.
