Wings: hyaline or nearly so; aiaterior margin with about eight 

 large brown spots along the margin, the fifth being at the tip of So; 

 between the large spots are scattered smaller dots. The whole disk 

 of the wing is covered with pale grejdsh-brown spots distributed as 

 in the figure. Venation as in fig. 34. 



Abdomen: tergum brown; sterna brown; apices of segments paler; 

 hypopygium dai-k brown.

The following description is translated from PhlMppi's original 



characterization of the genus ' by Osten Sacken. I have adopted 



this translation ^ almost as it stands : 



Head email, globose, attenuated behind, produced anteriorly into a stout hori- 

 zontal rostrum. Eyes globose, rather remote. No ocelli. The antennae in length 

 are equal to about three-quarters of the head and the thorax taken together; from 15 

 to 24 segmented; first segment cylindrical, stout; the second equal to one-third of 

 the first, subglobular; the following eight (to 12), cylindrical, subequal, emitting a 

 filament and thus forming a comb; the projection of the third segment is on the 

 external side and short; the fourth segment has one on the inside and another on 

 the outside; the segments 5, 6, 7, 8, 9, 10 and beyond, have on the inside a long pro- 

 jection; segment 11 has a short one on the inside; the nine following segments are 

 cylindrical and difficult to distinguish. Palpi 4-Eegmented, segments cylindrical, 

 the fourth stout, rather short, although a little longer than the third. The tibiae have 

 two spurs at the tip. 



The genus was not represented in any of the material that I received 

 for examination.
