base not closely crowded ; veins atend of humeral field immacu- 

 late. ....... (H. ) tuberculatus. 



B 2 . At the point where the scutellum of the vertex and the frontal costa meet, 

 between the apices of the lateral foveolae, a distinct sunken 

 transversely biareolate field or frontal fastigium easily distin- 

 guished both from the vertical scutellum and the frontal costa. 

 Posterior sulcus of the prozona terminating on the typical sulcus 

 in two forks, one at the lateral borders of the normal discal 

 scutellum, the other, by deeply cutting the lateral walls of that 

 scutellum, close to the median line. Median carina of metazona 

 posteriorly more or less subobsolete in the 9 • Markings of the 

 tegmina not distinctly pantherine. Mesosternal lobes separated 

 by a truncate but distinctly wedge-shaped median piece, the pos- 

 terior corners of the lobes being very broadly rounded. 



(Sticthippus.) 

 c 1 . Axillary vein of tegmina of 9 m no way entangled with the anal vein ; 

 maculations of apical third of tegmina obscure; humeral field of 

 wings uniformly infuscate apically. . ($■) calif ornicus. 



c 2 . Axillary vein of tegmina of 9 more or less entangled apically with the 

 anal ; maculations of tegmina as distinct on apical third as else- 

 where ; humeral field of wings apically maculate. 



(S.) marmoratus. 

 A 2 . Antennae of male attenuate or arcuate, in dried specimens often partly coiled 

 at the extremity; carina of pronotum intersected by two sulci, 

 and generally obliterated between them, but sometimes indicat- 

 ing the anterior sulcus only by sinuation ; posterior femora gen- 

 erally less dilated, the inferior border less arcuate. 



(Xanthippus.) 



6 1 . Antennae of $ usually as long as the hind femora, gradually attenuated 

 apically for at least one fifth their length, curled, cochleate, or 

 hooked at the tip in drying. Tegmina distinctly pantherine in 

 markings, occasionally obscured (in variation) by obsolescence ; 

 intercalary vein arcuate, approaching at least twice as close to 

 the median at its apex as near its base. Fuscous transverse band 

 of wings so far removed from apex as to leave a vitreous area, 

 especially in the $ , covering four marginal lobes or even more. 

 Pronotal carina with rare exceptions more or less obliterated 

 between the principal sulci. Summit of cranium commonly 

 carinulate between the eyes. 

 c 1 . Male of medium or large size. Tegmina surpassing the abdomen in both 

 sexes ; area of the ulnar fork rarely filled with only a single,
