 without cross veins, distinctly broader across scale than at basal fourth, 

 and with a denuded area near base. Legs very long and slender. 



Abdomen very narrow at attachment to thorax, subpetiolate, diverg- 

 ing to sixth segment, where it is about 1.3 times as wide as ptero- 

 thorax, thence converging abruptly to tip. Bristles on segment 10 yel- 

 low, all others dark brown, arranged as in its congener. 



Measurement of holotype : Length 1.76 mm.; head, length .198 mm., 

 width .290 mm. ; prothorax, length .222 mm., width .300 mm. ; meso- 

 thorax, width .330 mm.; abdomen, width at segment 6, .432 mm. 

 Antennal segments: i, 36; 2, 48; 3, 246; 4, 156; 5, 72; 6, 60; 7, 54; 

 8, 43; 9, 16 microns; total length of antenna, .73 mm.; width at seg- 

 ment 3, .0195 mm. 



Described from one female taken by Mr. James Zetek, by 

 sweeping, Moro Island, Panama (Bay of Panama, near Ta-

 at first confused, but easily distinguished by the characters 

 given in the key.
