Length of body, 7.5 mm.; of wing, same measurement. Two 

 females, Piura, Peru; one at light in house January 14, 1911, the 

 other taken on window screen of house February 7, 1912. 



Wholly pale straw-color, with black bristles, the third antennal 

 joint and proboscis more deeply tinged, and the frontalia more deeply 

 colored in one specimen. The thorax is verj^ faintly tinged with 

 flesh-color, more appreciable in perfectly fresh specimens. Disk of 

 mesoscutum is grayish-dusky centrally, especially behind suture; 

 four broken vittse of deeper straw-color are famtly apparent, the 

 median pair dividing the dusky area more or less clearly into three 

 vittse. The entire body is very thinly silvery poUinose, the bloom 

 only visible on close inspection. The first abdominal segment has 

 only lateral macrochsetse; second has lateral, and six very small 

 almost atrophied marginal ones; third has marginal row of eight 

 pronounced ones besides the lateral, which they equal in strength; 

 anal segment has a discal row of about same strength, and a marginal 

 row of weaker ones. Three equal pairs of marginal scuteUar bristles, 

 the apical pair decussate; a small separated discal pair. Two sterno- 

 pleural and three postsutural bristles. A small round black spot is 

 situated on front border of extreme wing-base, and the small cross- 

 vein of wing is narrowly clouded with black. The wing veins are 

 pale yellowish, the marginal ceU is deeply yellowish, and the costal 

 cells are hardly less so. The apical cell is well open in both speci- 

 mens. The third antennal joint is scarcely twice as long as second, 

 and the arista is delicately thinly hairy. There are four outwardly- 

 proclinate orbital bristles in a row on each side.
