/'. Antennae much longer than head and 

 pronotum together ; no median carina on 

 head, except sometimes posteriorly ; inter- 

 space between eyes as broad as the narrow- 

 est part of pronotal disk; longest hind tibial 

 spur scarcely longer than last tarsal joint. 



Fhlibostroma Scudder ( Note 6 ). 

 /■-. Antennae no longer than head and pro- 

 notum together ; a percurrent median carina 

 on head ; ' interspace between eyes hardly if 

 any more than half as broad as narrowest 

 part of pronotal disk ; longest hind tibial 

 spur distinctly longer than last tarsal joint. 

 Fsoloessa Scudder. 

 d". Radial veins in apical third of wings of ^ incrassate and con- 

 stricted, the discoidal field fenestrate (Orphulae). 



c^. Antennae relatively short, at most but little longer than 

 head and pronotum together ; fastigium of vertex with no median 

 carina ; scapular area of tegmina not specially dilated. 



/^. Foveolae of vertex more or less evident ; prozona 

 not much longer than metazona ; lateral lobes of prono- 

 tum transverse, i. e., deeper than long ; upper ulnar vein 

 of tegmina, at least in ^ , apically joining the lower ulnar 

 vein at a long distance beyond the end of the basodiscoidal 



field Orphiila Stal. 



/'-. Foveolae of vertex wanting ; prozona very much longer 

 than metazona ; lateral lobes of pronotum longitudinal, 

 longer than or fully as long as deep ; upper ulnar vein 

 of tegmina, at least in $ , apically strongly arched, joining 

 the lower ulnar vein not far beyond the end of the baso- 

 discoidal field. 



g^. Lateral lobes of pronotum slightly tumid in 

 descending by the obliquity of the upper portion ; 

 lateral carinae divergent on metazona ; discoidal field 

 of wings of (? distinctly narrowing apically.
