 Hesperotettix montanns BRUXER!, MS. 



Head varying from olivaceous to ochraceous, sparsely and rather 

 coarsely punctate with fuscous, the costae, front, and inferior margins 

 of the genae more or less pallid, an infraocular black bar and infra- 

 antennal black band, the clypeal incisures black ; fastigium more or less 

 infuscated or blackish, and the vertex with a longitudinal black stripe, 

 broadening posteriorly and there sometimes inclosing a pallid thread; 

 sides of the head behind the eye more or less streaked longitudinally 

 with blackish; antennae warm testaceous, with a greenish tinge near 

 base. Pronotum of the same ground color as the head, but the dorsum 

 often with more or less of a testaceous or subferruginous tint, the sulci 

 narrowly marked in black, a moderately broad mediodorsal bright or 

 dull white stripe rather narrowly margined, sometimes with the excep- 

 tion of the metazona, with black or fuscous; lateral lobes much varie- 

 gated on the prozona by an irregular assortment of brief, longitudinal, 

 black, rarely dark-green bars, sometimes more or less connected to form 

 a gently oblique moderately broad belt. Pleura and tegraina as in 

 H.festivus, and the femora similar, but the hind femora almost always 

 furnished with a moderately broad pregenicular salmon colored com- 

 plete annulation; hind tibiae and tarsi as in H.fcstivus. Supraanal
