segment stout, subglobular, yellowish ; second segment stout, some- 

 what swollen. Eyes jet black, very prominent, slightly emargi- 

 nate anteriorly. Palpi rather short, grayish brown, and thickly 

 clothed with hairs of the same color; basal joint thick, subconic, 

 second slender, longer than the slightly stouter third, the fourth 

 very slender, nearly twice the length of the preceding. Labrum 

 yellowish white basally, the anterior margin dark brown and the 

 dark color extending some distance on each side. Occiput and 

 posterior portion of the head straw yellow, slightly darker on 

 median line. Thorax with a pair of submedian, yellowish brown 

 lines tapering posteriorly and becoming obsolete at the posterior 

 third; narrow median line yellowish and with double row of yel- 

 low, slender scales. A sublateral, broad, yellowish stripe is pres- 

 ent posteriorly and is separated from the submedian stripe and 

 its opposite by a yellowish area thickly clothed with slender, yel- 

 lowish scales; a small, black spot near the middle and a little to 

 one side of the submedian stripes. Pleura and lateral anterior 

 margin of prothorax and base of scutellum yellowish brown, po'S- 

 terior margin of latter thickly clothed with long, yellowish hairs. 

 Abdomen greenish yellow^ and with irregular, sooty spots, par- 

 ticularly along the sublateral line, and clothed with rather short, 

 pale hairs. Ventral surface similar, apical segment paler, termi- 

 nal processes blunt, slightly curved, bearing many rather long, 

 curved setae. Legs pale straw yellow, ungues simple. Wings pale 

 straw yellow, clothed with similarly colored scales, which are 

 slightly thicker along the anterior longitudinal veins. Petiole

 second nearly one half; posterior cross vein interstitial with 

 mid cross vein. • Halteres pale straw yellow, base somewhat 

 enlarged, pedicel Yerj slender, tip rounded, spatulate. 



Described from a specimen bred June 28, 1904.

 times as long as wide; internal margin nearly straight, outer, 

 rather regularly curved and the apex distinct, chitinous, brown. 

 Posterior two thirds of the inner margin of the inner paddle, 

 fringed with long, nearly colorless spiny processes. Posterior 

 appendages nearly conic, simple, and at their base an inconspicu- 

 ous pair of subtriangular lobes. 



The larva, remarkable on account of its transparency, is very 

 difficult to detect in water, the only portions visible being the 

 deeply pigmented eyes and air sacks in the thoracic and abdominal 

 segments. This transparency is retained in alcoholic specimens 

 and also in those mounted in balsam. 



Larva. Head, somewhat elongate, subconic. Basal segment of 

 Antennae long, deeply notched at base and tipped with four nearly
