KEY TO THE SPECIES OF EREMOPEDES, FEM.\LES. 



A. Ovipositor long, more than two times as long as the pronotum. 



B. Larger, the posterior femora 19 mm. or more in length, very rarely as little as 



18 mm. 



C. Ovipositor as long, <jr almost as long, as the jiosterior femora; lateral lobes 



of tiie pronotum not so well developed as in the alternating category, the 



posterior sinus less distinct. 



D. Color variable but without dorso-lateral white stripes, .scudderi, p. 333 



D^. Color green, conspicuously marked with a pair of dorso-lateral white 



stripes on the pronotum and abdomen albofasciata , p. 337 



C/. Ovipositor usually no more than two-thirds as long as the posterior femora; 

 lateral lobes of the pronotum well developed, the posterior sinus distinc-t.

posterior sinus distinct. Prosternum unarmed, or armed with a pair 

 of short blunt spines rarely quite distinct and acute. Legs armed as 

 in the type species, but the posterior femora are apparently less elon- 

 gate. Abdomen moderated plump, o])scurely carinate. Wings con- 

 cealed in the female, in the male projecting somewhat beyond the pro- 

 notum. Ovipositor considerably shorter than the posterior femur; 

 cerci of the female simple, pointed, of the male triangular, very stout, 

 shaped as shown in lig. 36. 



Color generally uniforml}" brownish, sometimes 3'ellowish, the outer 

 face of the posterior femur sometimes with an elongate black streak; 

 in some specimens the lateral lol>es of the pronotum are dark and the 

 lower margins yellowish, and some specimens have the pronotal disk
