24 STOMA ZEYLANICA. 



Since writing the above I have examined a specimen collected 

 by Dr. A. Willey at Trincomalee on October 4. L908, and have also 

 received an example taken by Mr. W. Ormiston at Haldummulla 

 in November. 



On September 10 Mr. W. Vaughan obtained a second specimen 

 at Arawa, and a few days later bred a third from a pupa found 

 suspended from the upper surface of a leaf of Dimorphocalyx glabel- 

 la^ in the same locality. Furnished with this information, ami 

 thanks to Mr. Vaughan's kind assistance. 1 was able to visit Arawa 

 on several occasions during December and found the moths quite 

 common. They were at first obtained rather sparingly by beating 

 D. glabellas, but later on I found them in abundance flying in the 

 bright morning sunshine (about 10 to 11 a.m.) around the flowers of 

 Leea sambucina (Sinh. " Bouroula "). In several cases I noted 

 that the moths were actually feeding on the flowers, their tongues 

 unrolled and thrust violently into the flower in search of food. 

 In other cases they were settled on the leaves, when they hung 

 down freely suspended by the first two pairs of legs, the wings folded 

 and held out at right angles, the tip of the abdomen strongly curved 

 upwards, and the posterior legs with the tibia' extended at an angle 

 between the wings and the abdomen, and the tarsi curved inwards 

 until the distal tarsal joint nearly touched the apex of the abdomen. 



An examination of a long series shows that 0. vaughani may 

 differ from the type, as described above, in the following points : — 



(1) The white spots on the first segment of the fore wing are some- 

 times developed into distinct, though narrow, transverse bands. 



(2) The white bands on the hind legs are sometimes very indistinct. 



(3) The fifth abdominal segment is usually less suffused with 

 white scales. The narrow white bar on the fourth abdominal 

 segment, however, is always very distinct and characteristic. 



The larva will probably be found to feed inside the fruit of 

 Dimorphocalyx glabellus (Sinh. ' k Weliwenna "), from which I also 

 beat an example of 0. vaughani at Alutnuwara on December 1G, 

 1908.

(Plate A., figure 4.) 

 B. J., WL.582. 



Distribution. — Peradeniya. Not known outside of Ceylon, and 

 at present only recorded from a single tree of Dillenia retusa in the 

 Royal Botanic Gardens. 



Early Stages. — The egg and young larva are unknown. 



Larva. — The larva feeds inside the fleshy fruits of Dillenia retusa 

 (Sinh. " Godapara"), emerging from the fallen fruit when full-fed 

 to suspend itself for pupation on any neighbouring object.
