316 ENTOMOLOGICAL NEWS. [July, 'l6 



Wings hyaline to slightly brown tinged ; stigma black, shorter than 

 I have seen in gracile. 



9 . Labrum yellowish brown, darker at base, shading out insensibly 

 to the pale lower border. Genae, rhinarium and frons in front olive, 

 the two latter the darker, the frons sometimes dark reddish brown. 

 Nasus black, one specimen with an obscure spot on either side. Frons 

 in front with the pale areas, as compared with the male, generally 

 greatly more extended with the result that in some cases the black 

 is reduced to a longitudinal median stripe, wider above and below. 

 Head above as in the male with the postocular spots more bluish; in 

 some cases there is on either side a small round brown spot just be- 

 hind and external to the antenna, and indistinct areas of the same 

 color in front of the median ocellus. 



Prothorax similar to male, but pale color bluish. 



Thoracic pattern similar to male, but pale blue replacing the yel- 

 lowish colors of the latter, except in the posterior triangular area of 

 the metepimeron which is more or less distinctly yellowish. Mete- 

 pisternum from the wings to slightly below the level of the stigma is 

 a darker blue than the color which bounds it on both sides and below 

 (in the male the corresponding area is more or less slightly more 

 green than the surrounding areas). 



Abdominal segments 1-7 similar to male; 8 black (pale basally on 

 either side in one case), apex pale beyond the spines (and in one case 

 for a distance anterior to the spines equal to about one-half the part 

 posterior to the spines) ; 9 with apical half or two-thirds blue, this 

 blue encroaching on the black in a large quadrangular median spot 

 which reaches the base of the segment or is separated therefrom by a 

 narrow transverse line of black; 10 blue. Seen from the side similar 

 to the male but with blue or bluish replacing green ; 8 in one specimen 

 with a blue basal spot as described in dorsal view, in others black, the 

 narrow inferior yellowish margin slightly widened basally; 9 with the 

 blue appearing as a large distal superior triangular spot, the base of 

 the triangle on the apical border of the segment, extreme lower mar- 

 gin of segment yellowish; 10 blue, lower half paler and duller. Ap- 

 pendages black. Vulvar spine large, black tipped. 



Legs as in male, but black greatly reduced especially on parts distal 

 to the femora. 



Wings as in male, but stigma light brown.
