e 3 . Fuscous markings of apical half of tegmina irregularly maculate with 

 a tendency to a transverse arrangement but with ill defined very 

 irregular margins and occupying perhaps half the whole area. 

 f x . Dorsum of prothorax more heavily and coarsely rugulose ; tegmina 

 relatively long, distinctly surpassing the abdomen in the 9 ; the 

 darker tints of the tegmina generally prevail over the lighter, 

 particularly in the middle of the tegmina ; fuscous band of wings 

 relatively broad. ..... (A^.) aff rictus. 



J" 2 . Dorsum of prothorax less heavily and coarsely rugulose ; tegmina 

 relatively short, not exceeding the abdomen in the 9 ; darker 

 tints of tegmina subordinate to the lighter, particularly in the 

 middle of the tegmina ; fuscous band of wings relatively 

 narrow. ....... (A'.) toltecus. 



c 2 . Male of small size. Tegmina of $ shorter than the abdomen ; area of the 

 ulnar fork rarely filled with more than a single row of cells and 

 then only for a portion of its length. Metazona plane above, 

 with obscure or no indentation anteriorly. 

 d 1 . Shoulder (or extreme base of front margin) of tegmina as dark as the 

 rest of the base ; markings of tegmina more or less ^obscure and 

 blurred. ....... {X. ) altivolus. 



d' 2 . Shoulder of tegmina with paler markings contrasting with the rest of 

 the dark base ; all markings of tegmina sharp and distinct. 

 e 1 . Antennae of 9 almost as long as the pronotum ; pronotum of 9 

 nearly half as long again as its extreme dorsal width. 



(A'.) cupidus. 

 e 2 . Antennae of 9 considerably shorter than the pronotum ; pronotum 

 of 9 but little longer than its extreme dorsal width. 



(A^. ) pumilus. 

 b 2 . Antennae of $ distinctly shorter than the hind femora, apically attenuate 

 for rarely more than one eighth their length, at most arcuate or 

 broadly uncinate in drying. Tegmina rarely though sometimes 

 distinctly pantherine, usually irregularly mottled with moder- 

 ately large alternate blotches of dark fuscous and gray, and api- 

 cally dotted with pale fuscous ; intercalary vein usually straight, 

 rarely approaching the median much nearer at its apex thai- 

 next its base, never more than twice as close. Fuscous trans- 

 verse band of wings so near the apex that even in the 9 rarely 

 more than two marginal lobes are covered by the sometimes 

 apically infuscated vitreous area. Pronotal carina sometimes 

 scarcely subdued between the principal sulci. Summit of cra- 

 nium commonly not carinulate between the eyes.
