HEMIPTERA OF COLORADO. 
77 
depressed within; lorae as long as clypeus 
and narrower than clypeus at base; genae 
narrow, narrowly but rather deeply depressed 
next to the compound eyes and beneath the 
antennae, lateral margins almost straight, 
slightly concave, not attaining the tip of 
clypeus, moderately broad beneath the lorae; 
front one-third longer than wide, two times 
the length of the clypeus, sides below the 
antennae nearly straight but rapidly in¬ 
curved near the clypeus. V^ertex minutely 
transversely wrinkled, apex very broadly 
rounded, length at middle slightly less than 
that at the eyes, width between the eyes four 
and a half times the length at the middle. 
Pronotum two and five-sevenths times the 
length of vertex, two and one-fourth times 
broader than long, curvature five-ninths of 
the length, posterior margin slightly con¬ 
cave, disc minutely transversely rugulose. 
Scutellum finely indistinctly shagreened, 
transverse groove rather broadly depressed 
and strongly angled forward. Last ventral 
segment with hind margin moderately pro¬ 
duced at the middle, truncate, the edge 
either side gently curving to the rounded 
lateral angles. Color uniform pale green. 
Eyes brown. Basal angles of scutellum 
sometimes pale yellow. Nervures of elytra 
and wings colorless. 
Length 5.6-6.5 mm. Described from seven 
females. 
Male: AVith the greenish color below 
much more pronounced. Spots at basal anglas of scutellum sometimes nearly obso'Iete. 
Length 5 mm. Described from five males. 
Colorado Springs August 3d (Gillette). Fort Collins 
August 26tli on Helianthus annuus; Steamboat Springs, 
July 15th on willow (Baker). These specimens were 
examined by Mr. YanDuzee and said by him to be identical 
with the eastern form generally known under the name 
pallid us. 
Variety A. We also have numerous males and females 
which correspond exactly in structure and general coloration 
with this species, which have the dark \Aing nervures of 
nervatus. Steamboat Springs, July 15th on willow (Baker). 
Variety B. We have further three females which also 
correspond in structure, but are quite yellowish and have 
large spots within the basal angles of the scutellum black, 
and the tips of the elytra smoky. Leadville, August 28d 
(Gillette).
