468 DR. T. A. CHAPMAN ON THE SPECIES | Apr. 27 
It is no wise related to placida. placidula has a coloration 
similar to that of placida; owgarra has a very green tint, looking 
at first sight quite a different insect. In the Tring Collection is a 
specimen, rather deep black-blue, but fairly typical placidula, from 
Gunong Tjan, Malay Pens.; a very similar specimen, except that it 
possesses white patches (like puspa) on all the wings, from Upper 
Aroa Riv er, N.G.; a typical owgarra from the same locality, and 
another owgarra from Obi Major. 
This shows a very wide range for the species—Malay Peninsula, 
Moluceas, Borneo, and Australia. The identity of the appendages 
in specimens from these widely separated districts appears to 
remove any suspicions one might entertain that sinrgalensis and 
melena were varietally related to placidula; singalensis having 
the clasps, &e., much larger, and melena@ much narrower,

The appendages are very like those of ¢enella ( placidula), the 
spinous process being small and almost lost by being pressed down 
on the upper angle of the extremity of the clasp, which ends in a 
nearly transverse line. It differs by its larger size, 0°88 mm. 
long, against 0°62, and by the ter ‘minal half being g very definitely 
narrowed into a long neck-like portion. The whole clasp, and 
especially the base, is ‘much broader than in melena. 
De Nicéville seemed in much doubt as to this being a “ good ” 
species (Butt. Ind. vol. 11. e 108), and Bingham sinks it as a var. 
of huegelii. singalensis is, however, a very distinct species, 
whilst hwegelit is a form oa or grolus. 
In the Druce Collection there is a series of this species from two 
localities in Sumatra. They are of a much darker, deeper blue 
than those from Ceylon, with a strong tendency to a dark border 
and to spots round the margin of the hind w ing; they rather 
suggest very large, borderless puspa, such for example as one in 
the Tri ing Coll. from Palawan. 
In the Tring Collection is a very pale specimen from Java, 
looking very much indeed like a large pale huegelit, with very 
white fr inges on the hind wing and round the anal angle of fore 
wing. One would hardly recognise this as the same species as 
the Sumatran form without the indication afforded by the appen- 
dages; the fore wing is even of a different form, being more 
pointed. The under-side markings differ also, much as those of 
strophis (or dilectissima) do from limbata. 
De Nicéville refers to specimens from the Nilgiris ; an Indian 
specimen in the British Museum labelled singalensis is oreas, 
previously not known as Indian.  singalensis is probably not a 
continental form. 
De Nicéville & Elwes refer specimens from Lombok to huegelii 
(J. A. S. B. 1897, p. 695). As huegeliz almost certainly does not 
extend to Lombok, these specimens in all probability are singa- 
lensis. I have not, however, seen them.
