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. Vertex 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-fourtli times 

 broader than long, curvature five-ninths of 

 the length, posterior margin slightly con- 

 cave, disc minutely transversely rugulose. 

 Scutellum finely indistinctly i-hagreened, 

 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. .5-6. 5 mm. Described from seven 

 females.

 much more pronounced. Spots at basal angl3s of scutellum sometimes nearly obsolete.

Colorado Springs August 3d (Gillette). Fort Collins 

 August 26th on Helianthus annuus; Steamboat Springs, 

 Jul}^ 15th on willow (Baker). These specimens were 

 examined by Mr. VanDuzee and said b}^ him to be identical 

 with the eastern form generally known under the name 

 pallidus. 



Variety A. We also have numerous males and females 

 which correspond exactly in structure and general coloration 

 with this species, which have the dark wing nervures of 

 nervatus. Steamboat Springs, July 15th on willow (Baker). 



Variety B. We have further three females which also 

 correspond in structure, V)ut fire quite yellowish and have 

 large spots within the basal angles of the .-cutellum black, 

 and the tips of the elytra smoky. Leadville. August 28d 

 (Gillette).
