 1 1. DI is"" 11 in diameter ; the veins are black, and the basal part of the stigma 

 I >lack, but beyond it is dark fusco-castaneous ; the castaiieous portion ( lying 

 beyond the tip of the first median cell) is three times as long as broad, ex- 

 tending half-way down the upper border of the first subcostal cell : the third 

 costal cell is comparatively narrow at tip, and the tip of the wing is somewhat 

 pointed ; the vein separating the areola or second subcostal cell from the 

 third costal cell is partially obliterated, and the areola is rather small, sub- 

 quadrate, broadest at the open side ; there is the slightest possible trace of 

 the lower extremity of the vein separating the united first subcostal and 

 second median cells, but the vein bordering the upper side of the third 

 median cell is perfect throughout ; the vein separating the third and fourth 

 median cells is gently curved, subsinuate and partially obliterated in the 

 middle.

 of wing beyond stigma, 2.f mm ; greatest width of third costal cell, 0.35 mm .

A single specimen and its reverse show little besides the greater part of 

 the front wing and the tip of the hind wing; crushed chitinous masses rep- 

 resent parts of the abdomen, and perhaps of the thorax : the wing is uniformly 

 hyaline, with the slightest possible trace of infumation next the base, and 

 is profusely covered with tapering microscopic hairs, averaging 0.01)5""" in 

 length in the third median cell, seated upon minute chitinous annnli 0.01" 

 diameter; the veins are black, or toward the tip and on the hind wing c 

 taneous, and the stigma is dark testaceous; most of the stigma is broken, 

 I. ut enough remains t.p slimv that it is apparently not >o broad as in the other 

 species here described, and it extends less than half-way down the upper hol- 

 der of the first subcostal cell ; apicallv the third costal cell is comparatively 

 broad, and the tip well rounded : the vein separating the areola from the third 

 costal eell is nearh obliterated, and the areola is rather small, and shaped
