 [Tepic, Jalisco.] 



Tuxpan, Jalisco. September 4, 1903. (McClendon.) One female. 

 The following key based on the female will serve to separate several 

 species studied: 



A. — Fastigium broad; eye ovoid; disk of the pronotum with the 

 greatest width about two- thirds the length ; posterior margin 

 of the pronotum obtuse-angulate ; lateral lobes of the prono- 

 tum higher than long. 

 B. — Form heavy; fastigium rather blunt; face somewhat 

 rounded ; posterior femora heavy, the slender distal portion 

 less than one-third the total length, 



occidentalis (Saussiu-e). 

 BB. — Form rather slender; fastigium acute; face distinctly angu- 

 late ; posterior femora with the slender apical portion more 

 than one-third the total length, . . mysteca (Saussure), 

 A A. — Fastigium rather narrow; eye elongate-ovoid; disk of the pro- 

 notum with the greatest width but slightly more than half 

 the length; posterior margin very broadly obtuse-angulate; 

 lateral lobes longer than high, .... ingenita Bruner.

Guadalajara, Jalisco. August 6, 24, September 14 and 18, 1904. 

 (McClendon.) Sixteen males, thirteen females. 



These specimens are not typical viridis, and more material and study 

 may show that they represent another form. The tegmina and wings 

 reach to, or almost to, the tip of the abdomen in all the females, while 

 the males have those members considerably exceeding the apex of the
