probably also on wild leguminous plants. Davidson and Bell reared 
it on a vetch, Zornia diphylla. 
Z. gaika , Trim., has two spots on the costa of the forewing below, 
one on either side of the discocellular spot. It appears to occur in grass 
and low herbage throughout India, though best known from hill locali¬ 
ties. Z . otis, Fabr., has no costal spot below and is the last of this genus 
which de Niceville regarded as distinct. Accepting this view, the species 
is widespread in India ; he records rearing it on Alysicarpus vaginalis 
in Calcutta. 
Lampides is also widespread in India, L. elpis, God., light metallic 
blue above, rather less so than L. celeno., Cram., (celianus, Fabr.) which is 
milk white above. The former feeds on the cardamom (Elettaria carda- 
moma ) where this plant grows, the latter on the Dhak ( Butea frondosa) 
and on Heynea trijuga. For the accurate identification of these insects 
as for particulars of this family, the student should consult the third 
volume of de Niceville’s Butterflies of India, and Bingham’s volume 
II of the Butterflies in the Fauna of India. An account of L. elpis will 
be found in Indian Museum Notes, Yol. I, p. 11. 
Catochrysops is regarded by de Niceville as containing three species, 
while he lists nine. C. strabo, Fabr., has a “ distinct small dusky costal 
spot between the disco-cellular and discal bands on underside of forewing ; 
eyes hairy.” While the others have not these characters, C. cnejus , 
Fabr., has two nearly equal black spots at the anal angle of hindwing 
above, while C. pandava, Horsf., has but one such spot, in each case in 
the male. The first of these has been reared once from Vignacatjang, 
the second from Cajanus indicus, and other common pulses (Plate 
XXXII), the third from Cycads. All are common in the plains and may 
be captured readily. Tarucus theophrastus , Fabr., is the commonest 
of all these butterflies and is readily found as a larva on the ber 
(Zizyphus yujuba). The flat green larvae eat oh the epidermis much as 
a snail feeds and gradually denude the branches of leaves; the smaller 
bushy plants are preferred and one may frequently see a number of the 
little butterflies clustering on one little bush to sleep. De Niceville, 
in commenting on the number of species made by some writers, urges the 
breeding of this species in large numbers on this common foodplant; 
the views of two authors as to^ what constitutes a species are rarely
