This species is the largest of the genus and is the onl}^ foim 

 with apple green coloration and very broad wings. No resem- 

 blance or generalit}^ of structural characters would appear to show 

 close affinity of this species to any other in the genus. The sub- 

 genital plate of the male indicates that the species finds its nearest 

 relatives in the group to which tolteca belongs, while the coloration 

 is more like that of the elegans group. 



Described from a pair from the states of Sinaloa and Guerrero, 

 Mexico. 



Single Type here selected : cf ; Hacienda de la Imagen, Guerrero, 

 Mexico. Elevation 4000 feet. (H. H. Smith.) [Biologia Col- 

 lection in British Museum.] 



We here describe the only non-alcoholic specimen at present be- 

 fore us. 



Description. — cT ; Guadalajara, Jalisco, Mexico. August 12, 1893. (J. F. 

 McClendon.) [A. N. S. P.] 



Size very large and form rather heavy for the genus. Head with greatest 

 width contained one and eight-tenths times in depth, occiput rounded, 

 slightly declivent toward the fastigium, the latter narrow, compressed, 

 subequal in width with an appreciable longitudinal sulcus on the dorsal 

 surface, lateral margins roundly elevated, fastigium in full contact with 

 frontal fastigium for full length of both, this sulcus dorso-arcuate; eyes 

 small, but moderately prominent, narrowly ovate in outline, in length 

 less than that of the infra-ocular portion of the genae. Pronotum with 

 dorsal length about one and four-tenths the greatest (caudal) dorsal width; 

 dorsum of pronotum very slightly depressed with'n the margins; lateral 

 carinae of dorsum of pronotum faint and widely divergent in less than the 

 cephalic third, then sharply defined and widely divergent caudad with a 

 distinct angulation, the lines of divergence scarcely arcuate; cephalic mar- 

 gin of dorsum of pronotum straight, caudal margin very broadly arcuate; 

 lateral lobes of pronotum with length subequal to depth, the ventro-cephalic 

 angle obtusely rounded, the ventro-caudal angle rather broadly rounded, the
