Cuneus pale. Membrane infuscated with a short blackish ray at 
apex of the areole, the nervures yellowish. Antenne black with pale 
incisures; the feet infuscated with the base of the femora pale. I 
took numbers of this neat little species about the lower end of Fallen 
Leaf Lake, near Tahoe, California. 
7. Macrotylus infuscatus n. sp. 
Allied to the preceding; dull fuscous with the costal margin pale 
or largely pale, sometimes greenish-testaceous in the female. 
Length 5 mm. 
Head subhorizontal. Vertex scarcely flattened, the front becom- 
ing strongly convex anteriorly as in the typical forms of this genus, 
with a deep constriction at the base of the clypeus. Clypeus prom- 
inent, a little produced at apex as in many of our species. Eyes 
large, viewed from the side nearly vertical and reaching much below 
the middle of the side of the head. Antenne rather long; the basal 
joint surpassing the apex of the clypeus by one-half its length; second 
two and one-half times the length of the first; the third about equal 
to the second; fourth flattened and about equal to the first. Prono- 
tum long, strongly narrowed anteriorly, scarcely half as wide before 
as behind; sides sharply carinate throughout, a little sinuated, the 
humeral angles prominent. Elytra parallel or slightly widened 
behind; wing cell with a hamus. 
Ground color pale testaceous; tinged with greenish on the prono- 
tum, head and beneath; shaded with fuscous, especially in the males; 
pronotum, excepting the lateral edges and sometimes the callosities, 
scutellum except the outer angles of the basal lobe, and the elytra 
except the costal margin, more or less deeply infuscated, sometimes 
becoming a blackish-fuscous; disk of the front at times infuscated, 
the clypeus usually black and polished. Cuneus usually pale or 
decolored. Membrane deeply infuscated with pale nervures and a 
small black ray beyond the tip of the areoles. Antenne black with 
pale incisures, often with a broad pale annulus on the second joint. 
Legs pale, the femora more or less dotted with fuscous; the knees, 
tips of the tibia and the tarsi black. Above clothed with long gray 
pile giving the insect a hoary aspect. 
Described from numerous examples taken about the lower end 
of Fallen Leaf Lake, California, in July, 1915.
