Hind tibiae relatively short, shorter than the hind tarsi without 

 the claws. 



Female. — More robust than the male ; the head about 6 mm. 

 wide (5 in the male) and paler colored; the labrum is largely 

 light yellowish brown, and the brown on nasus and frons be- 

 low in front is paler and duller, less sharply contrasted with 

 the adjacent bluish gray parts, and, on the nasus, reduced in 

 extent. Vertex yellowish brown, the ocellary ridges lighter 

 in color; occiput similar to that of the male, slightly paler. 



Prothorax patterned as in the male with yellowish brown 

 replacing the black of the latter. 



Thorax light reddish brown, little if any darker on the dor- 

 sum, marked with bluish gray with the same pattern as in the 

 male, except that there is a faint trace of pale color on either 

 side on the dorsum just in front of the antealar sinus; under 

 parts and coxae slightly paler than in the male. 



Abdomen robust, colors and pattern obscure and ill-defined, 

 probably due to postmortem changes ; i largely pale, apical 

 half or less of dorsum and an ill-defined median lateral spot 

 brown; 2 largely pale, with no defined pattern, but apparently 

 much faded so colors in life cannot be described ; 3-5 apparently 

 as in the male, with the dorsal basal pale areas more extensive, 

 extending apically about one-half the length of each segment 

 on 4 and 5 ; 6 black ; 7 light brown, without trace of pattern 

 in the dried specimen; 8-10 indefinitely patterned black and 

 brown, black predominating. Sterna of segments 2-5 ending 

 apically in a small spine-like projection. No trace of ventral 

 spine or tubercle on i. Appendages yellow, brown at the ex- 

 treme base. 



Wings hyaline, no trace of colored areas, slightly greenish 

 tinged to or beyond the nodus especially in the anterior part of 

 the wings ; costa brown. Stigma brown, covering 4 to 4.5 cells
