436 INSECTA SAUNDERSIANA, 
Diy. n. 
Structure of the wing-veins much like that of Div. D. Meig. Dipt. 
i, 122, pl. 4, f. 15, but the discal areolet is much longer, and the trans- 
verse veinlet between the third externo-medial vein and the subanal is 
much nearer the base of the discal areolet.

East Indies. 
Diy. n. 
Structure of the wing-veins like that of Div. E. Meig. Dipt. i. 125, 
pl. 6, f. 2, with the exception of the first externo-medial vein, which is 
not forked. 
LIMNOBIA FLAVICEPS ? Foem. 
Limnobia flaviceps? Wied. Auss. Zweifl. i. 550, 16. 
Wiedemann describes the wings of L. flaviceps as fuliginous; in the 
insect here referred to that species they are blackish, with a white band 
which traverses the interior half of the discal areolet. 
South America. 
Diy. n. 
Mediastinal vein at a little before two-thirds of the length of the 
wing ; subcostal ending at about three-fourths of the length, connected 
with the radial by a transverse veinlet at its tip; radial and cubital 
springing from a common petiole, which is less than half their length, 
and which forms a right angle near its base; radial forked near its base ; 
cubital forming near its base a very obtuse angle, whence proceeds the 
first externo-medial ; the latter is rectangular near its base and is 
forked towards its tip, and is connected with the third externo-medial by 
two transverse veinlets; the outer one of these forms a slight angle, 
whence proceeds the second externo-medial yein; third externo-medial 
connected with the subanal by a transverse veinlet, which joins the 
middle of the hind side of the discal areolet.
