Manipur and the Borders of Assam. 345 



Callamesia, gen. nov. 



Allied to Amesia, but the primaries of a more triangular 

 (Euploea-like) form ; the first subcostal branch running into 

 the costal vein instead of running freely to the margin, both 

 first and second branches emitted much further from the end 

 of the cell, third and fourth branches forming a much narrower 

 fork to apex ; upper radial nearly straight instead of curved ; 

 lower radial emitted from the posterior angle of the cell instead 

 of from the third median branch ; submedian and internal 

 veins united beyond the middle by a transverse veinlet*; 

 secondaries much more oval than in Amesia^ but with similar 

 neuration. Antennse pectinated in both sexes ; palpi por- 

 rected ,• legs more slender than in Amesia ; genitalia of males 

 not covered by the great horny incised shield common to 

 Amesia. Type G. midama.

Herr Buchecker thinks that this genus should be placed 

 (with its near ally Caloschemia) next to Epicopeia, on account 

 of its having no internal vein to the secondaries.; it, how- 

 ever, differs from Epicopeia in having four branches to the 

 median vein in all the wings, a radial vein being emitted from 

 the inferior angle of the cell in each instance ; this is also the 

 case with Deilemera, PitasiJa, Trypheromera, Leptosoma^ and 

 other genera of Nyctemeridse. Though it is impossible, 

 without knowing the earlier stages of a genus like this, to 

 come to any final decision as to its proper location, it appears 

 to me that one character of venation should be of equal im- 

 portance with another. In all probability the internal vein 

 is merely aborted. 



* This very aberrant character, pointed out to me by Herr Buchecker, 

 first satisfied me that two genera were confounded under Ame&ia.
