wings pellucid, feebly infuscated apically, the veins and cross veins 

 blackish fuscous. Hind femora very variable, the outer face varying 

 from olivaceo-testaceous with fuscous incisures to dark almost blackish 

 fuscous, the most distinctly marked specimens with the base broadly 

 and obliquely yellowish testaceous, and a middle oblique band of no 

 great width of the same color; inner side red; hind tibiae obscure 

 glaucous, becoming luteous toward the base, rather densely pilose, the 

 spines black-tipped. Supraanal plate of male triangular, rather small, 

 tectate especially apically, with a narrow basal median sulcus, bounded 

 by high and heavy walls, which do not extend over half the plate; 

 furcula composed of a pair of very small, rounded, attingent lobes, 

 barely projecting beyond the edge of the last dorsal segment; cerci 

 about as long as the supraanal plate, slender, tapering throughout 

 but slightly more in the basal than the apical half, feebly compressed, 

 acuminate, feebly incurved in the apical half; infracercal plates brief, 

 concealed. 



Length of body, male, 17 mm., female, 21 mm. ; antennae, male, 5.5 

 mm., female, 6 mm. ; tegmina, male, 14 mm., female, 18 mm. ; hind 

 femora, male, 10 mm., female, 11.75 mm. 



Forty-one males, 35 females. Mexico, Sumichrast; Mexico, April,

Specimens in my collection, poorly preserved, seem to indicate the 

 presence of two other species of this genus in Mexico, one at Vera Cruz, 

 the other at Tehuan tepee. 



14. HYPOCHLORA. 



(v7tox\K)po?, greenish yellow.) 



Hypochlora BRUNNER (pars), Rev. Syst. Orth. (1893), p. 145. 



Body slender, compressed, very thinly pilose. Head not prominent, 

 the summit gently arched, the fastigiuni descending with moderate 

 rapidity, the face- re treating considerably; interspace between the eyes 

 broad, the fastigium scarcely sulcate, the frontal costa rather narrow, 

 not nearly so broad as the space between the eyes, sulcate, percurrent, 

 and subequal; eyes moderate in size, not very prominent, similar in the 

 two sexes, about half as long again as broad, and distinctly longer than 

 the anterior infraocular portion of the genae; antennae moderately 

 stout, somewhat longer (male) or a little shorter (female) than the head 

 and pronotum together. Pronotum subequal, even in the female, very 

 feebly and gradually enlarging in passing backward, with a distinct 

 percurrent median carina, the disk very broadly subtectate, passing by 

 a rounded angle hardly forming a lateral carina into the vertical lateral
