54 SPOLIA ZEYLANICA. 
(2) The small form. Average about 20 mm. 
The male is a rather dulk-violet-blue (almost matching Z. 
parrhasius 3), the markings of the veins very indistinct. The 
brown marginal border on the fore wing is extremely narrow, 
and the sub-terminal spots and white line on the hind wing 
are wanting, except in interspaces 1 and 2. Under side hind 
wing : sub-basal row of three black spots, of which the lower 
is often very indistinct. 
The two females are very similar, but the smaller race have 
the blue on the upper side much darker, and on the under side 
show only three sub-basal spots instead of fowr. The eyes are 
smooth. 
The large race is very common in the low-country of Uva, 
and is a very rare visitor to Haldummulla. I have not taken 
it above 3,000 feet. 
The males settle in numbers on wet patches on the roads 
or on the sand in river beds, and have rather a quick flight 
if disturbed. They usually, however, settle again quickly. 
The females are much scarcer, and are most likely to be found 
on weeds in abandoned paddy fields or chenas. 
The small form is apparently confined to the dry zone, and 
is extremely common in the Northern Province. Its habits 
are those of a Zizera, both sexes fluttering about together over 
short grass, and frequently settling on flowers. I have never 
seen the male on wet patches on the roads. It is especially 
plentiful at Elephant Pass (Jaffna) in December and January. 
I have never yet found both forms in the same district. 
The small form occurs sparingly at Hambantota, so one might 
expect to find both near Tanamalwila, on the boundary of the 
Uva and Southern Provinces.-“So far I have failed to take 
either there. I have taken the large form at Trincomalee.

Socotra, Arabia, India, &c. 
There are two varieties of the under side. In the first, all 
the black markings are very slender, and the post-discal band 
on both wings is a practically continuous slender line. In the 
second the markings are much broader, and sometimes rusty 
brown in colour. The post-discal band on the fore wing 
consists of six well-separated oblong spots ; on the hind wing
