HIPPISCUS. 149 



the tegmina opposite the middle of the intercalary 

 vein but little broader than the others ; the fuscous 

 band of the wings narrow, hardly touching the 

 margin anywhere and often widely interrupted 

 between the arcuate fascia and the humeral vein. 

 g. The darker markings occupying one-half or more 

 of the tegmina, normally and completely con- 

 tinuous in the middle half of the tegmina and 



usually broader than the pale interspaces . . . 12. conspicuus, Scudd. 

 gg. The darker markings occupying much less than 

 one-half of the tegmina, broken or partially 

 broken by the nervules into maculations in the 

 middle of the tegmina and usually narrower than 



the pale interspaces [13. eremitus, Scudd.] 



ff The transverse band of the anterior margin of the 

 tegmina opposite the middle of the intercalary vein 

 much, generally twice or more, broader than the 

 others ; the fuscous band of the hind wings 

 moderately broad, reaching the margin over half 

 its course and hardly or but slightly interrupted 



at the anal vein 14. pardalinus, Sauss. 



dd. Intercalary vein of the tegmina separated near its ex- 

 tremity from the median by a moderately wide space ; 

 markings of the tegmina often somewhat blurred or 

 ill-defined, but sometimes perfectly sharp ; transverse 

 band of the wings generally narrowed somewhat at the 

 anal vein, but less noticeably than in the alternative 

 category and never obsolescent; process of the meta- 

 zona normally rectangulate. 

 e. The fuscous markings of the apical half of the 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. 

 /. Rugosities of the dorsum of the pronotum irregularly 

 distributed; median carina of the metazona but 

 slightly elevated, scarcely arched; the transverse 

 fuscous bars of the tegmina with tolerably regular, 

 rounded, and sharply limited outlines ; hind femora 



distinctly and very obliquely barred exteriorly . .15. maculatus, Scudd. 

 ff Rugosities of the dorsum of the pronotum more or 

 less distinctly ranged into series parallel to the two 

 sides of the process ; median carina of the metazona 

 considerably elevated, distinctly arched ; the trans- 

 verse fuscous bars of the tegmina scarcely rounded,
