5 Elongate forms ; ocelli basal of the anterior margin of the 

 eyes, on the vertex lo Tetigoniini 



5a Stouter forms ; ocelli apical of the anterior margin of the 

 eyes, on the vertex ((^yponidae auctt ) 9 Penthimiini 



6 Vertex raised perpendicularly at the sides and base. Ex- 

 terior discoidal area of tegmen undivided to the apical cells 

 7 lassini 



6a Vertex not raised at the sides and base. Exterior discoi- 

 dal area divided (in the long winged forms at least) (7^ 



7 Head exceedingly declivous ; ocelli on the vertex ventral 

 of the bend of the head; .spines and bristles on hind tibiae some- 

 what diverse in different forms 



(Bythoscopidae auctt ) 3 Eurymelini 



7a Vertex usually more or less porrect ; r.celli (if present) 

 on the angular margin of the head (8) 



8 Radial, median and brachial veins ver\- ob-cure basally, 

 (apparently springing independently from the basal cell or unit- 

 ing close to it, except Aneono and Dialcciicoptcryx'^ ; ocelli ab- 

 sent or feeble 5 Eupterygini 



8a A'enation normal (except in short winged forms, or if ob- 

 scure, then so all over) ; ocelli on the angular margin of the 

 head, or touching it dorsally, rarely obsolescent (9) 



9 \"ertex strongly emarginate basally, ocelli in jjits on the 

 angular luargin ; legs spin\- 2 Stenocotim 



9a Vertex rarely much emarginate basally. ocelli never in 

 j)its, (or if so, then the legs bristly, not spiny) . .4 1 'hrynr/norplimi 



10 Head laminate or at least elongatcly produced. X'enation 

 degraded 6 Ce])haKlini ( restr.) 



10a Head never elongately j)roduced. never laminate 



(incl. Kahavaluinae ) 1 1 Alegophthalmini 



Tribe Ledrini. 



This tribe is nearly always characterized as having a folia- 

 ccous pronoitum, owing to the fact that Lcdra is the only Euro- 

 pean genus and that the tribe is not represented in North Ame- 

 rica. It is characterized by the more specialized legs and bv 

 the dorsal position of the ocelli. l)ut is not altogether natural. 

 Some forms, e. g., Rhotidus, have a verv close reseiubbmce to 

 Phrynomor])hine genera such as .■liniidioii, l)ut are distinguished 

 by the position of the ocelli.
