 Melanchra mutans. 



When studying the eggs of this moth I was struck by the dissimilarity 



of the eggs m some of the batches. This led me to examine the parent 



moths more closely, and, although they were almost similar to the type 



specimen, there were slight differences in the size, colouring, and clearness 



of the markings, and these, combined with the dissimilarities in the eggs, 



caused me to class the parent moths as two distinct varieties. I examined 



batches of eggs of eight specimens of variety A, and in all these both the 



parent moths and individual eggs of different batches were startlingly alike. 



Of variety B, I only had the good fortune to examine batches from three 



moths, and the dissimilarities of these and their eggs when compared with 



the others, and their similarity to one another, led me to class these as 



another variety. 



Variety A. 



This moth has a slightly greater wing-expansion than the type speci- 

 men. The colouring is brown and grey. The markings, although of the 

 same form as in the type specimen, are much more distinct. 



Variety B\ 



The colour of this moth is a rich reddish-brown. As in variety A, the 

 wing-expansion is slightly greater than in the type specimen, but is not so 

 great as in variety A. The markings are white with black margins, and are 

 beautifully distinct.

 Head grey-brown. Palpi and antennae ochreous brown. Thorax brown, 

 crests absent. Abdomen grey-brown, tufts rufous. Forewings covered with 

 dull silvery (lead-coloured) scales, the rather indistinct lines being bright 

 rufous. Two distinct marks on costa close to base, being portion of a 

 broken indistinct line across wing. At ^ there 

 are two other distinct marks on costa, continu- 

 ing as ill-defined lines across wing. Orbicular 

 and claviform outlined in rufous. Orbicular 

 elongate. A very distinct line crosses between 

 reniform and orbicular, running straight across 



save for a slight outward bend at wine-centre. r . , ,.. ,l, _, , . ■

Kenitorm nas an ocnreous lunate mark m 



centre, margined by rufous on basal side, and also outwardly, but outwardly 

 is not distinctly defined. Close to termen there are faint traces of a rufous 

 line ; a series of slight rufous dots along termen. Cilia light ochreous, 

 with an ochreous line at base. Hindwings ochreous, slightly rufous towards 

 termen. Cilia dull rufous, with an ochreous line at base. 



A single specimen, taken by Mr. S. Hart at the Cape Egmont Light- 

 house, 20th March, 1911. Unfortunately, although Mr. Hart has sent me 

 quite a lot of valuable material from this locality, I have not been so 

 fortunate as to secure another specimen of this species.
