each patch, and a few greenish-silvery scales in each black spot, towards the lower part. The rest 
of the markings are three black spots on the hindwing, other markings on both wings being pale 
brown. 
The £ is purplish blue on the upperside, the outer margin of the forewing and costal 
margin of the hindwing rather broadly bordered with blackish brown ; ciliae whitish ; two rather 
large black marginal spots on the hindwing, both on the outside of the “ tail.” 
I have taken this Lycaenid in July and August and later in the autumn. 
Nacaduba atrata, Horsf. 
A rare insect here, apparently occurring chiefly in the autumn. The J will be figured 
later in black-and-white, from a specimen taken in October. 
The $ on the upperside is purplish-blue, with scarcely any brown marginal border. 
The $ on the upperside bears a superficial resemblance to the $ of jfamides bochus , but 
the blue in the forewing is bright sky-blue, metallic and in some lights silvery or almost white. 
The costal margin, apex and outer margin of the forewing are broadly coloured with very dark 
brown, becoming wider still on the inner margin. On the hindwing the general colour is chiefly 
brown, with a patch of blue shining scales towards the base of the wing. The markings of the 
underside are seen indistinctly on the upper surface. The antennae are barred on the underside 
with white, but not on the upperside. 
Beneath, both sexes are almost identical, the white and brown markings being generally 
very distinct. There is a large black spot just outside the “tail,” edged at the top with yellowish 
and marked at the bottom with greenish-silvery scales ; there are two small black spots at the anal 
angle, also with yellow at the top, and marked with a few silvery scales on the black. The inner 
spot is the smallest. 
Catochrysops strabo, Fabr. 
A common butterfly with a rapid and erratic flight, often returning in its tracks and 
settling suddenly on a leaf, with half-open wings. It is often very numerous indeed in the autumn, 
but occurs sparingly at other times of the year except January and February, when it seems to be 
absent. It here frequents wooded and bushy ground, gardens and similar localities, but at Kwei- 
hsien it was very abundant on an extensive grassy plain. It may be seen at flowers, but prefers 
overripe berries. The large spider, Fpeira metadata, seems fond of this butterfly, but he 
seldom refuses any Lycaenids which stray into his clutches, or for that matter any other butterflies. 
The $ and $ differ considerably on the upperside, as may be seen from the figures. 
The underside is practically the same in both sexes.
