male and very like the male introferens ; so unless the sexes are first 

 carefully separated out and associated, it is quite easy to range the two 

 species into a continuous series. As between the males I have never 

 been for a moment in doubt as to which was auxiliaris and which was 

 introferens. The female of the latter species, by the bye, is more like 

 the male agrestis than it is like its own mate. 



Rhizagrotis cloanthoides Grt., appears in Hampson's work as a 

 synonym of albalis Grt., in the bibliography ; but is referred to in the 

 description as, *' Ab. i. cloanthoides : whiter." In my original work 

 I placed them in this same way, before seeing the type of albalis in the 

 British Museum. After that I referred the two as good varieties at 

 least in my catalogue and, yet later, in my check list placed them as 

 good species. The latter conclusion I still adhere to. The type of 

 cloanthoides is in the old Graef collection and I have specimens com- 

 pared with it. I have also a series of albalis which agree with Hamp- 

 son's figure and description and with Mr. Grote's determination of 

 his species in the U. S. N. M. The two differ not only in maculation 

 but in the armature of the anterior legs, albalis having a series of long, 

 curved, claw-like spines on the outer side of the tarsal joints which are 

 absent or much reduced in cloanthoides. There is also a difference in 

 the armature of the mid-tibia ; but my material in cloanthoides is too 

 defective to make it possible to determine details now. 



Taken as a whole the number of points in which the synonymy in 

 the genus Euxoa has been changed from my original determinations is 

 remarkably small. Some of the changes suggested by Hampson are 

 correct and these are all noted here. Others of them are not well 

 founded, and so far as our differences related to Walker's species, I 

 believe Sir George has agreed that he was in error. As to those differ- 

 ences where lack of material in the British Museum prevented direct 

 or sufficient comparisons, they can be easily settled later, when material 

 becomes more abundant, and they affect no names on the " unknown " 

 list. 



Feltia cvanidalis Grt., is the only species (except olivia) of the 

 genus not represented in my collection and I have been trying to iden- 

 tify it with west coast examples of siibgothica with contrasting yellow 

 reniform. Hampson, however, places it next to my pectinicornis and 

 that is correct. It really looks like a faded, yellowish, washed-out 

 example of that species. It is passing strange that none of the Cali- 

 fornian collectors have again taken this species.
