LEPIDOPTEEA OP THE PAMILT ZYQMWLDJE. 355 



Peocotes, u. gen. PL XXVIII. fig. 1. 

 "VVings narrow, cell of secondaries wide, partially divided by a 

 recurrent nervure ; one radial ; discocellulars forming a conti- 

 nuous concave angular line, and equal in length ; second median 

 branch trifurcate, the forks emitted from its lower margin at re- 

 gular intervals, thus dividing it into three almost equal lengths. 

 Type, P. diminuta, Walker.

 Syntomis diminuta, Walker, I. c. p. 1592. 



NoTioPTEEA, n. gen. PI. XXVIII. fig. 2. 



AViugs moderately broad, cell of secondaries wide, partially di- 

 vided by a recurrent nervure emitted from the middle of the 

 lower discocellular ; one true radial, the lower radial being placed 

 at the end of the median nervure, thus forming a fourth median 

 branch ; upper discocellular short, oblique, lower twice as long, 

 angulated in the middle, the two together forming a zigzag line. 

 Type, iV. dolosa, Walker.

4. N. ? EXPANSA = S. expansa. Walker, Lep. Het. Suppl. p. 73. 



Thteassia, n. gen. PI. XXVIII. fig. 6. 



Nearly allied to the preceding, but with not only the lower 

 radial but also the third median branch emitted near together 

 from the lower discocellular ; the continuous line of the disco- 

 cellulars also less zigzag. Type T. subcordata, Walker.

I rather doubt the propriety of separating this genus from 

 the next ; for though slightly diflTerent in coloration, its large 

 palpi seem to be its chief structural distinction ; the pattern of
