sides below of segment 2, including the auricles and dorsal median 

 longitudinal bar on the apical half of the segment, pale; segment 3 

 with the sides pale below basally, and with a narrow longitudinal 

 mid-dorsal line, which is widest at the base of the segment, thread- 

 like through most of its length, and does not quite reach the apex; 

 segment 4 apparently entirely brown with the exception of a 

 reduced and frequently interrupted longitudinal mid-dorsal thread- 

 like line extending the full length of the segment except the extreme 

 apex, and a small pale area on either side below basally; segment 5 

 with a more or less distinct basal median spot, the remnant of the 

 dorsal line, and a small pale area on either side below basally; 

 segment 6 similar to segment 5, but the lateral and median pale 

 areas are slightly larger; in segment 7 these pale spots are joined 

 in a basal band, encircling the segment and occupying about one- 

 fifth its length; segments 8 to 10 black, segments 8 and q laterally 

 and segment 10 dorsally and laterally obscurely and indefinitely 

 mottled with dark reddish brown; segment 10 with the apical 

 inferior side obliquely cut; superior appendages yellow, the inferior 

 reddish horn, both tipped with black. The superior appendages 

 are 1.5 mm. long, and segments 8, 9, and 10, measured at mid- 

 height on the side, are respectively 2.4, 1.4, and .8 mm. in 

 length. 



Wings hyaline, very slightly tinged yellowish basally, venation 

 dark, stigma brown, covering three to four cells, 2 . 7 mm. long in 

 the front wing and 3 mm. long in the hind wing; antenodals of 

 front wing 12 or 13 mm., of hind wing 9 or 10 mm.; postnodals of 

 front wing 10 to 13 mm., of hind wing 9 or 10 mm. 



Legs weak, of median length, light reddish brown, darker 

 apically beginning on the apices of the femora; apices and angles 

 of the tibiae, and the tarsi black; the first femora darker above 

 through most of their length. Femora circular, tibiae quadran- 

 gular in cross-section. First femora with a longitudinal row of 

 very light yellowish-brown inconspicuous bristles on its ventro-
