NOTES ON THE SYNONYMY OF NOCTDID MOTHS. 265 



that it is considerably smaller. We have a good many of both 

 forms ; and if H. umhrosus is not distinct, H. succinea must also 

 be a variety ; there is no character on the upper surface of the 

 wings to separate either of them. It is possible that the 

 H. ruhrescens and H. separata of Walker may be varieties of 

 H. armigera. The former appears to be strictly confined to 

 Australia, but the latter has a wide distribution; there are 

 specimens in the museum from the Navigator's Islands, Queens- 

 land, Java, Formosa, Shanghai, Japan, and the Congo. The 

 pattern of both surfaces in each of these forms differs from that 

 of typical H. armigera; and, therefore, in the absence of actual 

 proof of their identity, it is better to permit them to stand as 

 distinct species.

The species, wrongly identified by Walker with H. spinosce, 

 H. definiens, and H. jmnctifera, are nearly allied species, not 

 belonging to Heliothis. 



As Grote suggested (Check List, p. 36, footnote), his 

 H. nuchalis is not distinct from the European H. scutosa. I am 

 not, however, prepared to say that H. phlogophagus is identical 

 with H. dipsacea; the latter always has a far less undulated 

 submarginal pale line on primaries, and a better defined dusky 

 nebula from reniform spot to inner margin ; it is usually, though 

 by no means invariably, smaller.

 In all probability, H. paradoxeus, Grote, will prove to be a 

 pale form of this species ; at present it holds its place fairly 

 well, from the absence of intermediate grades to the dark type, 

 although the pattern is identical in the two forms.
