prozoua plainly though feebly, sparsely and rather coarsely punctate, 

 the metazona closely punctate. Tegmina rather long ovate, nearly 

 twice as long as broad, and scarcely shorter than or at least three- 

 quarters as long as the pronotuin, green. Hind femora green, the 

 outer half of the upper surface ruddy, the under surface and the 

 oarina beneath the outer fiertl luteous; hind tibiae green, the spines 

 pale green with black tips. Abdomen green, becoming darker above, 

 the carina marked heavily with yellow and margined with blackish 

 green. 



Length of body, female, 23 mm. ; antennae, 7.75 mm. ; tegmina, 6 mm. ; 

 hind femora, 12.5 mm. 



Two females. Colorado, Morrison (U.S.N.M. [No. 710]; L. Bruner). 



Of the long-winged forms, this species most resembles H. festivus, 

 but is easily distinguished from it, apart from the great difference in 

 the tegmina.

Head pea green, fusco-puuctate in front, with a short blackish stripe 

 below the eyes, behind the pallid callosity; streaks of dark green pass 

 backward from the eye, and the vertex has a slender, mediodorsal fus- 

 cous stripe, narrowing anteriorly and ending at the base of the fastig- 

 iuin in a round blackish spot; antennae pale ferruginous, slightly 

 iufuscated apically. Pronotum shaped as in H. pratensis, pea green, 

 with a moderately broad, bright ferruginous, obscurely fuscous, mar- 

 gined, mediodorsal stripe, generally broader in the female than in the 

 male; and above the middle of the lateral lobes, but not reaching the 

 front margin nor passing beyond the prozoua, a blackish fuscous bar, 

 sharply delimited below, fading out above, bordered beneath and some- 

 times interrupted posteriorly above with pallid ; sides of the body green 

 except that the metapleura have an oblique pallid stripe, bordered on 

 the upper posterior and lower anterior sides with black. Tegmina con- 

 siderably shorter than the abdomen in both sexes, but particularly in 

 the female, the anal area and a little more than that ferruginous, its upper 

 limit sometimes infuscated, the remainder pea green. Femora almost 

 precisely as in H. pratensis; hind tibiae varying from pea green to pale 

 bluish green, the spines pale on basal, black on apical half; hind tarsi 

 coucolorous with tibiae or sometimes a little yellower. Supraaual plate 

 of male triangular, with straight sides and rounded subacute apex, 

 about as long as broad, with a broad and rather high tectate ridge 

 parallel to the margins, inclosing a deep, basally broad, triangular sul- 

 cus; furcula consisting of a pair of slightly projecting, moderate sized,
