usually with a complete double, row of cells. Metazona usu- 

 ally tumid centrally to a greater or less extent, and considerably 

 depressed or indentate anteriorly on either side the median 

 carina. 

 d 1 . Intercalary vein of tegmina near its extremity running so close to the 

 median as commonly to be hardly separated from it by more 

 than its own thickness ; markings of tegmina sharp and well de- 

 fined ; transverse band of wings distinctly narrowed, sometimes 

 obsolescent, at the anal vein ; process of metazona normally less 

 than a right angle. 

 e 1 . Bounding walls of the vertical scutellum and other carinae of the 

 vertex generally dull and low; metazona about two thirds as 

 long again as the prozona, its dorsum variable, its rugosities not 

 very prominent, rarely confluent ; transverse fuscous band of 

 wings usually very broad, in the second lobe below the anal vein 

 often more than twice as broad as the width of the lobe. 

 f x . Species of great size ; maculations on apical third of tegmina often 

 obscure by lack of depth of color, lessening the contrasts be- 

 tween the darker and the lighter spots, but sometimes sharp and 

 well defined ; fuscous band of wings generally very dark ; inside 

 of hind femora usually blue except the red apical third. 



(X.) corallipes. 



J" 2 . Species of rather small or medium size ; maculations on apical 



third of tegmina generally pure and with distinct contrasts ; 



fuscous band of wings generally fuliginous ; inside of hind 



femora usually wholly red. . . . (-A.) zapotecus. 



e 1 . Bounding walls of the vertical scutellum and other carinae of the 



vertex usually sharp and relatively high ; metazona twice as 



long as prozona, its dorsum centrally tumid, its rugosities prom 



inent and usually more or less confluent ; transverse fuscous 



band of wings usually narrow or moderate, in the second lobe 



below the anal vein rarely so much as twice the width of the lobe. 



f l . Transverse pale band of anterior margin of tegmina opposite the 



middle of intercalary vein but little broader than the others ; 



fuscous band of wings narrow, hardly touching the margin 



anywhere and often widely interrupted between the arcuate 



fascia and the humeral vitta. 



g l . Darker markings occupying one half or more of the tegmina, 



normally and completely continuous in the middle half of the 



tegmina and usually broader than the pale interspaces.
