268 PSYCHE. [June ,89*. 



y* 1 . Relatively slenderer forms, the tegmina relatively slenderer; last, 



forked branch of the discoidal vein of the hind wings usually 



arising about three fifths the distance from the base to apex of 



the wing, and in $ usually well within the limits of the transverse 



fuscous belt ; closed tegmina of $ surpassing the abdomen by 



at least one fourth their length. . . . {H.)rug~osus. 



p. Relatively stouter bodied forms, the tegmina relatively broader ; 



last, forked branch of the discoidal vein of the hind wings usually 



arising at about two thirds the distance from the base to apex of 



the wing, and in $ at the outer edge of the transverse fuscous 



belt; closed tegmina of $ surpassing the abdomen usually by 



less than one fourth their length. 



g x . Dark markings of outer fourth of tegmina clustered into regular 



connected transverse series. . . . (H.)compactus. 



g 2 . Dark markings of outer fourth of tegmina forming irregularly 



distributed minor maculations. 



h x . Markings of tegmina distinctly pantherine, marginal field 

 with numerous small blotches ; wings of $ fully twice as long as 

 broad ; hind margin of prothorax rectangulate. {H. ) varlegatus. 



h 2 Markings of tegmina hardly pantherine, resembling many spe- 

 cies of Trimerotropis, marginal field mostly occupied by two 

 large spots ; wings of <J scarcely twice as long as broad ; hind 

 margin of prothorax obtuse angulate. . . (//. ) suturalis, 



e 2 . Lateral canthi of pronotum acute, continuous throughout, arcuate ; 

 metazona of 9 scarcely longer than the prozona. {H. ) ocelote. 

 c 2 . Anterior extremity of scutellum of vertex prolonged, narrowing gradually, 

 in front less than half as wide as in the middle ; hind margin of 

 pronotum acutely angled (rarely, by variation, rectangulate) ;. 

 markings of tegmina hardly or not at all pantherine. 

 d l . Metazona with two pairs of distinct lateral rugae parallel to hind margin ; 

 basal discoidal field of tegmina, including the ulnar area, broadly 

 maculate ; apical half of tegmina multimaculate ; ulnar taenia of 

 hind wings stopping far short of the base of the wing, the inter- 

 mediate space filled with closely crowded cross veins ; veins 

 at end of humeral field more or less laterally stained with black- 

 ish fuscous at the cross veins, rarely absent. {H.) saussurei. 

 d 2 . Metazona without lateral oblique rugae ; basal discoidal field of tegmina,. 

 and especially the ulnar area, almost or quite immaculate ; apical 

 half of tegmina paucimaculate ; ulnar taenia of hind wings 

 almost reaching the base of the wing, the cross veins next the
