Show 1888.] FROM WESTERN INDIA. 293 Scotomera tristis, Butler, a synonym of Actenia gnidusalis, Walker, do I intend to cast the slightest slur on Mr. Butler's acumen. The specimens he had to describe were in so poor a condition that the only wonder is that he was able to describe them at all. I wish also to draw attention to two species in particular, both occurring in the collection, each of which varies in precisely the same respect from its nearest allies, viz. Oxira ochracea, Walker, and Euplexia (?) pectinata, sp. n. Both these species have the antennae of the male strongly pectinated. In all other respects, alike in markings and in structure, they agree, the former with the group of Graphiphora, of which G. dahlii of Europe is the type, the latter with Euplexia albovittata, Moore. The question at once arises, whether this structural exaggeration of a single organ (which obtains, it would seem, more especially in the equatorial regions) is sufficient, if unattended by any further departure from the type, to warrant the erection of a separate genus ; or is not rather to be regarded as an instance of what may be termed " specific aberration from a generic type."
