DISMORPHIN/E. I77 



with. The type is Z. xiphia (Fabriciiis), a common East 

 Indian species. 



GENUS LEUCIDIA. 



Leucidia^ Doubleday, Gen. Diurn. Lepid. p. 77 (1847); 

 Butler, Cist. Ent. i. pp. 35, 43 (1870); Schatz, Exot. 

 Schmett. ii. p. (i(i (18S6). 



Antennae with the club gradually formed ; palpi very short, 

 scaly, and bristly ; wings rounded ; sub-costal nervure four- 

 branched, the first joint emitted much before the end of the 

 cell, the second a little beyond; subcostal nervures of the 

 hind-wings stalked. 



This genus contains a few South American species. They 

 are the smallest of the Pieridce^ scarcely measuring an inch 

 across the wings. They are small wlute Butterflies, the type, 

 Z. elvina (Godart), being white or yellow, with the fore-wings 

 narrowly bordered with black ; another species, L. brephos 

 (Hiibner), is almost pure white. 



On account of the resemblance presented by Leptidia to 

 Dismorphia on the one hand, and to Euchloe on the other, we 

 place here Schatz's Sub-family Dis7norphi?ice. 



SUB-FAMILY II. DISMORPHIN^. 



Antennae slender, with a gradually-thickened, spindle-shaped, 

 or a suddenly-formed, distinct club. Palpi short, not reaching 

 beyond the head, with short scales above and on the sides, and 

 hairy in front. The middle and terminal joints are very small. 

 The sub-costal nervure five-branched, the branches very short, 

 and placed at equal distances. A pre-costal nervure present. 



The species of this group are delicate Butterflies, with long 

 wings. Most of the South American forms mimic species 

 of Ithomiince.
