NO. 3535 MICROLEPIDOPTERA, IX — OBRAZTSOV 581 



tricini. The tribe includes the genera Polyortha Dognin, Ardeuiica 

 Meyrick, Pseudatteria Walsingham, and others not yet described and 

 presently in Polyortha. Thus, a key to the genera of the Polyorthini 

 cannot be given until a revision of the genus Polyortha is completed.

Type species. — Pseudatteria potamites Walsingham, 1913 (by 

 monotypy and original designation.) 



Description. — Head smooth, sides of vertex with longer and 

 raised scales. Antenna simple or pseudoserrate, in male densely 

 short ciliated and with setae protruding; cilia not longer than width 

 of antenna] shaft, setose in female only; scapus long, somewhat 

 flattened. Labial palpus about four times width of eye or even 

 longer, porrect, slightly curved downward; basal segment pronounced; 

 second segment with appressed scales, longest of all segments, almost 

 uniformly broad along whole length; terminal segment rather long, 

 acute. Proboscis moderate. Thorax smooth. 



Forewing smoothly scaled, elongate-subovate; costa strongly 

 arched; apex broadly rotundate, termen obliquely convex; tornus 

 broadly rotundate; dorsum almost straight, basally arched. No 

 costal fold in male. Twelve veins, all separate; Sc very gently bent; 

 Ri from before middle of discal cell; R2 more than twice as near to 

 R3 as to Ri; R3 twice as remote from R.j as R4 is from R5; latter vein 

 running to apex; internal vein of discal cell from between Ri and R2; 

 M,, \l2, AI3, and Cui almost equidistant; Cui from lower angle, 

 Cu2 from about two-thirds of discal cell; Ai weak; basal fork of 

 A24.3 shorter than one-fourth of entire vein.
