reflexions, the humeral region narrowly obscure yellow; a small 

 yellow spot above the wing-root; scutum destroyed by the pin; 

 scutellum and postnotum dark. Pleura black with purplish 

 reflexions; a conspicuous yellow cross- band extending from the 

 wing-root to the mid-coxa. Halteres broken. Legs with the coxae 

 and trochanters yellow ; remainder of the legs broken. Wings sub- 

 hyaline with three conspicuous, dark brown cross-bands, arranged 

 as follows : the first in the bases of cells E, M and Cu and as a 

 spot in cell 1st A ; second band extending from the tip of Rl along 

 the cord, this band broadest anteriorly, gradually narrowed pos- 

 teriorly but wide and conspicuous for its entire length; terminal 

 band occupying wing-tip, including cell R2, distal half of /?3, a 

 little less than the distal half of R5, most of 2ml M2 and the distal 

 half of If 3 ; cells C and 8c dark brown ; veins dark brown. Vena- 

 tion : Sc ending a short distance beyond the origin of Rs ; Rs 

 very strongly arcuated ; r at tip of R\ and on i?2 + 3 a short 

 distance beyond the fork oi Rs ; R2 + 2 longer than jB3 ; R2 short, 

 subperpendicular ; cells \sl M2 very long and narrow, proximal 

 end narrow, gradually widening distally, longer than the veins issuing 

 from it; m about one-third shorter than the outer deflection of 

 Mi ; basal deflection of Gu\ at the fork of M. 

 Abdomen broken,

Holotype, Sex ( ?), " Kad.," August 1857. 



Type in the collection of the Vienna Museum. 



Paratropesa amoena differs from P. fasciolaris (Wiede- 

 mann) in the closed cell Isl M2. It is very distinct from 

 all described species of the genus. 



The type bears a label in Osten Sacken's writing : 

 " Fliigelgeader von Limnobia fasciolaris W. und deshalb 

 vielleicht nov. gen." 



Toxorhina atripes, sp. n. 



General coloration dark brown, the front and thoracic pleura 

 silvery pruinose; legs brownish black; wings with a faint dusky 

 tinge, most intense near the wing-apex ; Scl ending about opjiosite 

 one-fourth the length of Rs; basal deflection of Cul at or just 

 beyond the fork of M. 



Female. — Length (excluding the rostrum) 4-8 mm. ; wing 4 mm. 



Rostrum dark brown, if bent backward extending to about 

 mid-length of the abdomen. Antennae dark brown. Front and 

 anterior part of vertex silvery grey ; remainder of head dark brown. 



Mesonotum dark bro\vn, unmarked. Pleura dark brown, con-
