AMBLYPODIA GEOTJP OF THE LYCLENTDiE. 97 



This species is very close to moorei raihi, but may be easily separated by the darker and 

 more purplish colour and rather broader borders of the upperside, whilst beneath the 

 transverse band differs, and in the secondaries the submarginal row is a very pronounced 

 feature which is quite wanting in moorei ; it is also more " spotted " than my species. 

 From davaona Semp. it can be distinguished by the purple being less dark, its borders 

 less wide, its size smaller, whilst beneath the transverse band of the primaries is 

 recurved, this in davaona being nearly straight.

Hab. Borneo ; Malacca ; Sumatra. 



Expanse, 6 & S , 38-41 mm. 



Further material shows me that this species will not come next to metamuta, as I 

 had originally placed it. In de Niceville's collection there is a very large series from 

 Sumatra, where it is evidently a common insect ; it can easily be separated from 

 avatha de Niceville as already mentioned. The genitalia are peculiar, the hooks are 

 strongly curved downwards at the base, the clasps are broadish, particularly at the base, 

 strongly excised in the centre of the upper margin ; the penis is straight for the basal 

 two-thirds, after which it is bent to a sharp upward curve.

This species may be separated from moorei Bethune-Baker by its decidedly larger 

 size, very much brighter and bluer colour, and narrower margins on the upperside of 

 the male. In the female the colour is brighter and more silvery than in the male, 

 whilst in moorei it is darker and more violet. 



I have only seen the pair sent me by Dr. Staudinger, in whose museum the types 

 remain.

This species is an obscure little insect, and is known to me only by the two types in 

 Mr. Rothschild's collection.
