g 2 . Darker markings occupying much less than one half of the teg- 

 mina, broken or partially broken by the nervules into macula- 

 tions in the middle of the tegmina and usually narrower than 

 the pale interspaces. - (X.) fremitus. 



J" 2 . Transverse band of anterior margin opposite middle of intercalary 

 vein much, generally twice or more, broader than the others ' t 

 fuscous band of hind wings moderately broad, reaching the 

 margin over half its course and hardly or but slightly inter- 

 rupted at the anal vein. . . . -(-X.) fiardalinus. 



d 2 . Intercalary vein of tegmina separated near extremity from the median 

 by a moderately wide space ; markings of tegmina often some- 

 what blurred or ill defined, but sometimes perfectly sharp ; 

 transverse band of wings generally narrowed somewhat at the 

 anal vein, but less noticeably than in the alternative category 

 and never obsolescent ; process of metazona normally rec- 

 tangulate. 

 e 1 . Fuscous markings of the apical half of tegmina hardly occupying so 

 much as half the space, arranged in generally transverse, well 

 defined blotches rarely so long as half the breadth of the 

 tegmina. 

 f l . Rugosities of dorsum of pronotum irregularly distributed ; median 

 carina of metazona but slightly elevated, scarcely arched ; 

 transverse fuscous bars of tegmina with tolerably regular, 

 rounded, and sharply limited outlines ; hind femora distinctly 

 and very obliquely barred exteriorly. . (A'.) maculatus. 



J' 2 . Rugosities of dorsum of metazona more or less distinctly ranged 

 into series parallel to the two sides of the process ; median ca- 

 rina of same considerably elevated, distinctly arched ; trans- 

 verse fuscous bars of tegmina scarcely rounded, with ill defined 

 irregular margins on apical half; hind femora obscurely or not 

 at all barred exteriorly. .... (Jf). tigrinus. 



e 2 . Fuscous markings of apical half of tegmina occupying fully three 

 fourths its area, arranged in well defined transverse bars nearly 

 or quite crossing the tegmina. 

 J" 1 . Dorsum of prothorax with very prominent, often sharp, rugosi- 

 ties ; fuscous band of wings very broad, not at all narrowed at 

 the anal vein. ...... (A.) leprosies. 



f 2 . Dorsum of prothorax with less prominent, though coarse but dull 

 rugosities ; fuscous band of wings narrow or if of medium width 

 then distinctly and considerably narrowed at the anal vein. 



( J A r .) paradoxtis.
