HIPPISCUS. 151 



length, at most arcuate or broadly uncinate when dry. 

 Tegmina rarely, though sometimes distinctly, pantherine, 

 usually irregularly mottled with moderately large alternate 

 blotches of dark fuscous and grey, and apically dotted with 

 pale fuscous ; intercalary vein usually straight, rarely 

 approaching the median much nearer at its apex than next 

 its base, never more than twice as close. The fuscous trans- 

 verse band of the wings so near the apex that even ia the $ 

 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 the cranium rarely carinate between the 

 eyes. 

 c. Median carina of the pronotum usually almost entirely 

 obliterated between the principal sulci ; markings of the 

 tegmina distinctly pantherine, mostly confined to the 

 anterior half or three-fifths ; apex of the axillary field 

 pallid ; the fuscous band of the wings somewhat obscure, 

 very narrow, narrowed at the anal vein ; inferior carina of 

 the hind femora high and strongly arcuate ; hind tibiae 



yellow [23. albulus, Scudd.] 



cc. Median carina of the pronotum usually distinct between 

 the anterior and principal sulci ; markings of the tegmina 

 not pantherine, but more or less marmorate, much as in 

 Trimerotropis, rather generally distributed ; inferior carina 

 of the hind femora usually normal, r,arely high or strongly 

 arcuate. 

 d. Lateral lobes of the pronotum slightly wider below than 

 in the middle by the retro-arcuate curve of the hind 

 margin; inferior carina of the hind femora not espe- 

 cially prominent. Band of the hind wings rather 



broad and continuing to the anal angle 24. neglectus, Thorn. 



dd. Lateral lobes of the pronotum equal, the hind margin 

 vertical and not retro-arcuate ; inferior carina of hind 

 femora more or less prominent. Band of the hind wings 

 variable. 

 e. Size small ; general colour brown. Wing-band incon- 

 spicuous and pale fuscous, not following the hind 

 border to the anal angle, the entire apex of the wing 

 dusky from the heavy infuscation of all the veins. 



Hind femora largely black internally 25. australis, sp. n. 



ee. Size large j general colour cinereous. Wing-band 

 rather conspicuous, broad, black, and following the 

 hind border to the anal angle ; apex vitreous. Hind 

 femora bright red internally 26. rnontanus, Thorn.
