black, the scape, except extreme tip and the pedicel ferruginous. 
Scape broadly dilated at the tip; pedicel two-thirds the leng-th of the 
first fiagellar joint; second to seventh slig-htly wider than long, the 
following- growing- more slender, bnt of eqnal length. Prothorax very 
closely and rather finely pnnctate in front. Pronotnm and mesonotum 
deeply and coarsely i)mictate, the pronotnm closely, bnt the mesono- 
tnm more sparsely apically toward the center. Parajvsidal fnrrows 
vaguely defined by pnnctnres, scapid e pnnctate, with no trace of any 
groo^'e. Scntellnm with a pnnctate frennm, two times as wide as long-, 
its snrface coarsely xinnctate, the pnnctnres mnch sparser toward the 
center. Postsentellum with a very short spine. Metanotnm finely 
rngose, more or less distincth^ areolated anteriorly, and with a 
V-shaped carina on each side, but no median one anteriorly. Meso- 
pleura with a large smooth s]>ace. metaplenra with a smaller one. 
Metanotnm with its npper lateral angles produced. Abdomen elongate 
OA ate, as long as the head and thorax, coarsely longitudinally striated 
above, except along the j)osterior margins of the segments which are 
smooth and polished. Apical segments more or less punctate; sutures 
crenulate. Venter sparsely and rather coarsely punctate. Legs 
weakly spinous, clothed with glistening hairs. Wings infuscated, the 
costal cell hyaline. Stigma separated from the submarginal vein; 
stigmal vein recurved, a trifie- longer than the indistinct postmarginal 
one, with an imperceptible knob at the tip. Marginal vein indistinctly 
indicated, except at base and tip, where it is not visible. 
Two females sent me by Mr. Nathan Banks. They were 
collected at Falls Church, V^a., August 2. 
This species can be readily distinguished by the pale legs from 
any other in our fauna, except S. famelicum Say, which, however, 
has hyaline wings. 
The species of Sparaison so far discovered within the United 
States may be separated by means of the following table : 
1. Wings h^^aline, scapuhe with a distinct grooved longitudinal line, 
legs, except coxa% honey-yellow famelicum Say. 
Wings infuscated, scapuhie without a distinct grooved line.... 2 
2. Legs, except coxa?, honey-yellow, antenna! scape, honey-yellow.

Legs principally black, sometimes with the tibifie and tarsi lighter, 
antennie wholly l)lack .3
