portion to the length than in the male. Prosternal spine more acicu- 

 kte than in the male: interspace between the mesosternal lobes 

 slightly transverse, subequal in width to one of the lobes; metasternal 

 lobes separated caudad by a width equal to one-half that between the 

 mesosternal lobes; surface of the sternum punctate instead of sha- 

 greenous. Abdomen distinctly carinate mesad to the penultimate 

 segment: supra-anal plate subtectate in section, elongate trigonal in 

 general form, distal section moderately produced caudad with the 

 apex broadly rounded, proximal half with a distinct medio- 

 longitudinal impression, laterad with distinct carinae, which form 

 the proximo-lateral point of the plate thence strongly converge 

 to the mechan (longitudinal) section of the plate, represented distad 

 by parallel rounded shoulders, ventro-laterad of which the plate is 

 subcompressed : cerci short, broad at base, tapering, the apex blunted : 

 ovipositor jaws moderately compressed, dorso-lateral margins of 

 the dorsal valves faintly and irregularly crenulate. Cephalic and 

 median limbs normal, not inflated as in the male, rather short. 

 Caudal femora as in the male but differing in the ventral carina 

 having smaller but more numerous teeth. 



General color of head, thoracic and abdominal segments and 

 cephalic Hmbs bay, shading to auburn in places, the venter passing 

 to mununy bro"\vn. Fastigium sanford's brown; eyes bronzy argus 

 brown; antennae of the general color, paler proximad; clypeal suture 

 black mesad and laterad, the paired black spots found on the fourth 

 fifth and sixth segments in the male represented by smaller and 

 weaker dots. Median limbs paler than the cephalic ones, more 

 yellow ocher. Caudal femora bay with the dorsal face sanford's 

 brown, the genicular arches black, the lobes blackish with a decided 

 green tinge; caudal tibiae and tarsi cedar green, the distal portion 

 black, the spines black tipped.

In addition to the type and allotype we have examined four male 

 and two female paratjT)es. Of these one male bears an exact date,
