130 THE BUTTERFLIES OF CEYLON 
This is extremely plentiful at Haldummulla, but I have 
no specimens from any other locality. My notes give many 
localities for dara, but I cannot say for certain to which one 
of the group they refer. It usually settles on grass by the 
roadsides, but visits flowers in bright sunshine. 
and, T. satra. This may be a distinct race, but the slight 
differences in the genitalia rather point to its being a seasonal 
form of pseudomesa. 
The 3 closely resembles the ¢ pseudomesa on its upper 
surface, and I had placed it as such in my collection till I 
noticed the sex mark. It resémbles the figure of P. satra 
in “‘Lepidoptera Indica’ fairly well. Fruhstorfer says satra is 
confined to Ceylon. 
The yellow band is very narrow, and the spots in 4and 5 
are well separated from both the discal and apical series, 
There is a spot in 7, but none in 6. The band on the hind wing 
is not divided by brown lines. The female has the yellow 
markings greatly reduced, and the band on the hind wing is 
broken up by brown lines along the veins. The under side 
of the hind wing in both sexes has a very distinctive greenish 
tinge, which is, I believe, typical of dara. The prehensores 
differ slightly from those of pseudomesa, but the differences 
appear to be constant ; however, I have so far only been able 
to dissect six males. See Plate 5, figs. 31 and 32. 
I have taken it at Haldummulla, in March and May. 
3rd, T. mestoides. This is a small form. The clasp is 
near that of 7. rectifasciata but the sex mark of the male is 
quite distinct. 
The yellow band is almost always continuous, the spots in 
4 and 5 being joined to both the discal and apical series ; it, 
however, varies greatly in width. The band on the hind wing 
is not divided by brown lines along the veins. There is 
almost invariably a large spot in 7, but very rarely one in 6. 
In the female the yellow markings are much reduced, and the 
spots in 4 and 5 are not always joined to the apical series. 
I have caught one aberration of the female, now in the British 
Museum collection, in which the spots in 4 and 5 are quite
