legs in both sexes, and the bifid claws on all the legs in the Dismorphina, are 

 conclusive evidence that they are true Pierinse, and are in no way connected with the 

 Heliconinse.

A close examination of the members of the old genus Dismorphia, or Leptalis as it has 

 been more frequently called, reveals the fact that great diversity of structure exists amongst 

 them — so much so that we think it necessary to divide it into four separate genera, and 

 we believe that further subdivision will hereafter be found expedient. 



The main grounds of separation may be briefly stated as follows : — 



A. First subcostal branch of the primaries united with the costal. 



a. First subcostal branch of the primaries emitted beyond the end 



of the cell. 

 a'. Subcostal branch of the secondaries in the $ emitted far 



beyond the end of the cell. (Type Papilio amphione, Cr.) Dismorphia. 

 b'. Subcostal branch of the secondaries in the <$ emitted at the 



end of the cell. (Type Pieris nemesis, Latr.) . . . Acmepteron. 



b. First subcostal branch of the primaries emitted at the end of 



the cell. (Type Papilio melite, Linn.) . Enantia. 



B. First subcostal branch of the primaries free. (Type Pieris nehemia } Bd v.) Pseudopieris. 



Papilio amphione of Cramer may be considered the type of Hubner's genus Dismorphia 

 as here restricted, Dalman's name Leptalis being unfortunately strictly synonymous. 

 D. praocinoe of our region is the only truly typical species found there ; the other six 

 are all more or less aberrant, but for the present we think it advisable not to carry 

 generic subdivision further. 



The subcostal nervure of the primaries oiD.praxinoe reaches the margin at the apex 

 of the wing ; the upper discocellular is quite short, and meets the subcostal nearly at a 

 right angle ; the middle discocellular is bent to a right angle in the middle, and the 

 lower discocellular is nearly in a line with the third segment of the median ; the costal 

 side of the cell is a little longer than the median side. The second and third segments 

 of the median nervure of the secondaries are subequal, the lower discocellular is nearly 

 at a right angle to the latter ; the subcostal branch leaves the subcostal far beyond the 

 cell. In the female the apex of the primaries is of a different outline, and is prolonged 

 into a hook, into the point of which the upper radial enters ; the lower discocellular is 

 much shorter than in the male, and thus the median side of the cell is longer than the 

 costal ; the secondaries are narrower in proportion to their length ; the cell also is 

 narrower. The terminal joint of the palpi is very short, the middle joint being but
