Etitettix vanduzei n. sp. 



Face two-elevenths wider than long: clypeus one-third longer than broad, slightly- 

 constricted at the middle, nearly as bread before the apex as .at the base, basal suture 

 curved; lorae somewhat shorter and murh narrower than the clypeus; gonae 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 sliallow 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. Pronotuni twa 

 and a sixth limes wider than long, length once and a half 

 that of the vertex, curvature about one-halt 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 olf. Color pale 

 greenich 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 n.inute black spots at 

 bases of tibial spines, tips of tarsi infusjate. 

 Length 5 mm. Described from one female. 



Rabbit Ear Pass, Larimer County, July 20th (Baker). 



This species may prove to be Thamnotettix (sensu strict.). 

 It is certainly congeneric with E. clarivida. 



Chlorotettix unicolor Fitch.

Steamboat Springs, July 26th; Colorado Springs, August 

 3d (Gillette). 



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 lon{? 

 as head, pronotum, and scutellum together. Pronotuni short, length at middle four- 

 fifths that of vertex, anterior and posterior margins nearly parallel. Scutellum large, 

 normal. Elytra semlcoriaceous, 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 

 iiervures 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, apic il o-ll. Rostrum longer than the clypeus. Posterior 

 tibiae outwardly with two rows of mo lerate spines. Type, N. tumidifrons.
