LEPTALIS. 35 



Genus II. LEPTALIS Dalman. 

 Dalman, Anal. Ent. 39. (1823). 



Licinia Swainspn, Zoo!. III. 1st ser. t. 15. (1820). 

 Aeria, Dismorpuia, Enantia, Eiibn. 

 Pieris God'. 



Head small, scaly, and slightly hairy. 



Eyes round, prominent. 



Labial Palpi distinctly triarticulate, sometimes shorter than the head, sometimes very slightly 

 longer, clothed with scales and short hairs. Basal joints longer than the two other joints 

 combined, curved at the base ; second joint cylindric-ovate ; third joint shorter, obovate, rather 

 pointed. 



Antennce long, slender, very gradually clavate. 

 Thorax rather slender, covered with scales. 



Anterior Wings narrow, elongate ; pointed, falcate, or rounded. The subcostal nervure dividing 

 into five nervules ; the first thrown off a little before, or slightly beyond, the cell, sometimes 

 anastomosing with the subcostal; the second, third, and fourth thrown off at about equal 

 distances. Upper disco-cellular very short, or wanting ; the first discoidal, in the latter case, 

 springing from the subcostal nervure at the end of the cell. Lower disco-cellular very short ; 

 second discoidal nervule, especially in the males, sometimes so intimately united to the third 

 median, as almost to appear a fourth median nervule. 



Posterior Wings ovate, elongate, much broader than, and nearly or quite as long as, the anterior. 

 The discoidal nervure thrown off from the subcostal considerably before it branches; mostly 

 bent where it is joined by the short lower disco-cellular, so as to appear a fourth median nervule. 



Legs elongate, slender. Paronychia very narrow, triangular, nearly equal in length to the claws. 

 Pulvillus very small, or wanting. 

 Abdomen slender, extending beyond the wings. 



Larva and Pupa unknown ? 



This interesting genus is closely allied in many respects to the Heliconida:, and, as has been suggested by Dr. 

 Boisduval, may perhaps, at some future time, when the larva and pupa shall be certainly known, constitute a separate 

 group, connecting that family and the Pieridas. There seems to be considerable ground for doubting whether the 

 larva figured by Stoll be really that of Lept. Amphione. This larva is cylindrical, stout, furnished with two long 

 curved spines, placed on the sides behind the head. The chrysalis, which he says is " perpendicular," a term of 

 doubtful signification, is not figured. The larva appears much larger than would be expected for so slender an insect 

 as that which it is said to produce, and probably is that of one of the Danaida 1 .
