^utettix vanduzei n. sp. 
Face two-elevenths wider than long; clypeus one-third longer than broad, slightly 
constricted at the middle, nearly as broad before the apex as at the base, basal suture 
curved; lorae somewhat shorter and much narrower than the clypeus; genae broad, 
nearly flat, very broadly rounded outwardly; front about one-fourth longer than wide 
almost twice the length of the clypeus, gradually narrow¬ 
ing to the clypeus, superior angle very broadly rounded. 
Face and vertex finely shagreened. Disc of the vertex 
flat, two shallow pits immediately back of the large black 
spots near the anterior edge, once and a half as long on 
the middle as next the eyes, width between the eyes little 
more than twice the length at the middle. Pronotum two 
and a sixth times wider than long, length once and a half 
that of the vertex, curvature about one-half of the length, 
posterior two-thirds finely transversely wrinkled, with 
scattering shallow black punctures, posterior margin shal¬ 
lowly concave. Scutellum finely shagreened. Last ven¬ 
tral segment of the female with the hind margin nearly 
truncate, posterior angles obliquely cut off. Color pale 
greenish yellow. Face light yellow, sutures, spot beneath 
antennae, two transverse spots at the extreme base of the 
clypeus, two V-shaped marks on the genae, and two large 
curved spots immediately beneath the crest of the vertex, 
black. Vertex pale yellow with two large black spots on 
the disc, a little nearer to the eyes than to each other. 
Pronotum yellowish, with two more or less distinct trans¬ 
verse black lines, one just before the middle and the other 
next the posterior margin. Scutellum light yellow, trans¬ 
verse suture black. Elytra greenish subhyaline with nerv- 
ures yellowish. Tergum black, with broad lateral and 
narrow apical margins yellow. Venter pale yellow with median basal portions of first 
two segments black. Ovipostor black. Legs pale yellow with minute black spots at 
bases of tibial spines, tips of tarsi infuscate. 
Length 6 mm. Described from one female. 
Rabbit Ear Pass, Larimer County, July 20tb (Baker). 
This species may prove to be Thamnotettix (sensu strict.). 
It is certainly congeneric with E. clarivida.

Neocoelidia n. gen. 
Allied to Tinobregmus. Body short and robust. Head narrower than pronotum, short 
conical, rather obtuse and tumid; vertex expanded posteriorly behind the eyes, ocelli on 
extreme front edge, front very broad below, the sides nearly parallel. Antennae as long 
as head, pronotum, and scutellum together. Pronotum short, length at middle four- 
fifths that of vertex, anterior and posterior margins nearly parallel. Scutellum large, 
normal. Elytra semicoriaceous, without an appendix, but extending beyond the tip of 
the abdomen; the first sector but once forked in the proximal two-thirds, the inner 
branch connected with the second sector by a single transverse nervure, the latter 
entering an anteapical cell; apical areoles four. Wings well developed, margined, the 
nervures very strong, second and third sectors uniting before the marginal nervure, thus 
forming but one apical cell; a transverse nervure between second and third sectors form¬ 
ing a single, short, triangular, apical cell. Rostrum longer than the clypeus. Posterior 
tibiae outwardly with two rows of mo lerate spines. Type, N. tumidifrons.
