from Signoret only. Most of the species are mentioned as 

 living on Eucalyptus, whereas these from Natal come from 

 Acacia and Grevillca, both Australasian trees, so that, although 

 the food plants are not the same, the insects probably came 

 from Australia on the plants on which they were found, and 

 may or may not be special to them. This, I think, is all I 

 can do towards identification, and no one can do more in the 

 matter unless he has by chance in his possession similar 

 scales which have been identified. Possibly some Australian 

 entomologist, say, in Sydney, could say something more 

 definite from personal, local knowledge. The family is very 

 peculiar and interesting, and so I have ventured to keep two 

 of the scales. I shall be very glad to have any farther 

 information, if it should be forthcoming.

Mr. H. J. Elwes exhibited a large number of specimens 

 of Terias of the hecabe group, in order to show the amount of 

 seasonal and local variation which existed. He stated that 

 these variations had been a constant puzzle to lepidopterists, 

 and that the number of forms which had been described was 

 so great that many of them were impossible to distinguish or 

 identify. In the British Museum Collection the hecabe group 

 was represented by no less than 35 so-called species from the 

 Indian region alone, of which 12 or 13 were described by 

 Butler, and 10 by Moore. But when a large number were 

 arranged as he had here placed them, according to the season 

 of their capture, it would be seen that there was good reason to 

 believe that many of these forms were seasonal. In localities 

 where the difference of heat and moisture between the winter 

 and summer was great, as in the Himalayas, Punjab, Deccan, 

 China, Liu-kiu Islands, and to a less extent in the highlands 

 of Ceylon and Southern India, the winter brood of T. hecabe 

 appearing between December and March, together with some 

 of those taken in October and November, is marked by a 

 diminution or absence of the black border on the hind wings, 

 and the presence of more or less conspicuous chocolate 

 markings below, whilst in the same localities the summer 

 and autumn broods had almost without exception broader
