Scotomera tristis, Butler, a synonym of Actenia gnidusaUs, 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 tiie same 

 respect from its nearest allies, viz. Oxira ochracea. Walker, and 



Euplexia (?) pectinata, sp. n. Both these species have the an- 

 tennae 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. dahl'd of Europe is the type, the latter 

 with Euplexia alhovittata, 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."
