REHN AND HEBARD 65 



Color Notes. — The general color of the non-alcoholic male now 

 before us is immaculate apple green, which has faded considerably 

 on body and proximal portion of the tegmina to straw color. An- 

 tennae nearly black, annulate with very dark green. The apices 

 of the wings are burnt sienna, and the fourth dorsal abdominal 

 segment bears on each side a small and conspicuous rounded black 

 spot situated near the caudal margin of the segment. The dried 

 alcoholic specimens have lost all trace of original coloration with 

 the exception of these two small black spots which in these indi- 

 viduals are as prominent as in the non-alcoholic specimen. 



Distribution. — The species is known to occur on the west coast 

 of ]\Iexico, from Mazatlan southward to the state of ,Guerrero. 

 Guadalajara is more interior than any other locality at which the 

 species has been taken.

This species is closely related to /. gracillima from which it may 

 be readily separated by its much more attenuate structure and, in 

 the male, by the much longer and more decidedl}^ and regularly 

 curved cerci. Though bearing a striking general resemblance to 

 the species allied to /. tolteca, and showing relationship to them in 

 the fact that the cephalic tibiae have the proximal extremities 

 much swollen and narrowing sharply below the tympanum, the 

 insect differs widely from those species in many important respects. 

 The absence of articulate styles on the subgenital plate of the male, 

 the small supplementary spine on the genicular lobes of the 

 cephalic and median femora and the rounded apex of the tegmina 

 indicate that the present species is more closely related to the very 

 different appearing northern species related to /. elegans.
