508 Mr. E. E. Austen on new 



with rather long yellowish hair; palpi hazel-brown"^, very 

 slender; antennce slender, first joint not at all incrassated 

 and only slightly longer than the second ; second and third 

 joints dark iDrown, first joint lighter (brownish tawny) except 

 at distal extremity. Thorax with a tuft of golden pile 

 on the metapleura?, besides the tufts already mentioned. 

 Abdomen : the short whitish hair clothing the dorsum some- 

 what longer and more conspicuous on the sides of the first 

 and second segments than elsewhere; under side of second 

 segment also clothed with short whitish hairs; remainder of 

 venter inconspicuously clothed with blackish hair. Wings 

 with extreme base, costal cells, basal fourth of first basal 

 and basal sixth of second basal cell, marginal cell from a 

 point above the origin of the third vein to the end, and a 

 continuation (apical blotch) which fills out the apical portion 

 of the first submarginal cell, and the upper angle of the 

 second submarginal, shading off below, dark brown; the 

 proximal margin of the transverse bund runs from the origin 

 of the third longitudinal vein to the posterior upper angle of 

 the fifth posterior cell, and thence (sometimes obliquely for- 

 wards) to the sixth vein, on which it ends ; the distal 

 margin of the transverse band runs from a point below the 

 second longitudinal vein, and a little beyond the level of the 

 end of the first longitudinal, to the hind margin of the wing 

 at the end of the vein separating the third and fourth 

 posterior cells. Proximally, the transverse band thus fills 

 out the exti'cme tips of the first and second basal cells, and 

 the end of the anal cell; distally it includes the base of the 

 second posterior cell, and diagonally bisects the third 

 posterior cell. The whole of the discal cell is included, but 

 there is sometimes a tiny hyaline fleck at its extreme base. 

 The ai)ical portion of the wing below^ the apical blotch is 

 entirely infuscated with a brownish suffusion, and the 

 infuscated area is separated from the transverse band by a 

 milky streak, which ends on the vein separating the second 

 and third posterior cells. Halteres dark brown. Legs : 

 coxge dark brown ; femora reddish brown, tips of hind pair 

 darker; tibife, except extreme tips, front tarsi, and last two 

 joints of middle and hind tarsi dark brown ; third joints of 

 middle and hind tarsi brownish ; front and middle tibiae in- 

 crassated, hind tibios also somewhat incrassated.
