82 TETTIGID.E OF NORTH AMERICA 



small tooth from the middle of the front margin, on either 

 side at the junction with the frontal costa a little sulcate, occi- 

 put naked behind the eyes; crown of head viewed in profile 

 appreciably elevated above the eyes. Frontal costa in profile 

 strongly advanced beyond the eyes, between the eyes moder- 

 ately but sharply sinuate, between the antennae protuberant, 

 nearly as far as the vertex above, at the apical junction with the 

 median carina of the vertex angulate, rounded at the apex, 

 viewed in front furcate, the rami quite widely separated, dis- 

 tinctly diverging to the median ocellus. Eyes very small. 

 Antennae moderately short, the articles rather elongate. Pro- 

 notum anteriorly truncate, the antero-dorsal margin sometimes 

 scarcely angulate, posteriorly extenuate acute, passing beyond 

 the posterior femora, but not so far as the wings; dorsum 

 between the shoulders broadly tectiform, humeral angles 

 strongly distinct, carinate, angulate; median carina of pro- 

 notum distinctly elevated, percurrent, anteriorly between and 

 in front of the shoulders longitudinally conipresso-arcuate, 

 posteriorly scarcely concave; posterior marginal carinae dis- 

 tinct, between the carinae rugose; lateral lobes of pronotum 

 posteriorly bisinuate, the superior sinus moderately deep, the 

 inferior sinus strongly angulate incised, the median lobule 

 between the two obtuse angulate; the posterior inferior angle 

 of the lateral lobes obtuse, inferior margin below rounded, 

 laterally somewhat expanded. Elytra strongly elongate sub- 

 acuminate towards the apex; wings fully explicate passing 

 the pronotal apex; margins of first femora entire; the second 

 femoral margins dilate, below subsinuate, in the male strongly 

 expanded, being nearly or quite one-half as broad as long, 

 the first half being distinctly ampliate viewed in either direc- 

 tion; posterior femora of moderate size, the first article of 

 posterior tarsi longer than the second and third together, 

 the pulvilli flat below, the first pulvilli small, acute, the 

 second little longer than the first, the third nearly as long as 

 the first and second together.
