Sept., 1907.] Smith: Notes on Some American Noctuids. 143 



Euxoa expiilsa Wlk. , I made out to be the same as insulsa, and in 

 that Hampson agreed with me, referring both to fnessoria. I have 

 seen no reason to change my opinion on their identity and of course 

 this species follows insulsa in its removal from the list of viessoria 

 synonyms. All the other names which appear under messoria in the 

 British Museum catalogue are already properly referred in my own work. 

 Euxoa choris Harv.= cogiians Sm. There are two allied yet dis- 

 tinct species in my collection, one of which I have under the name 

 choris the other as my cogitans. In the British Museum only one of 

 these species is represented. My identification of choris was from a 

 colored drawing of the type made many years ago for Dr. C. V. Riley. 

 It will be necessary, before the relation of these two names can be 

 settled, to send over examples of both of the species that I have, for 

 direct comparison with the Harvey type. At present my material is 

 not sufficient to permit me to do this ; but I hope to do so in the 

 near future. 



Agrotis insignata Wlk. Walker described two species under that 

 name on two different pages of the same volume. The first of these 

 I referred as a synonym of insulsa and the second, renamed illata by 

 Walker in a subsequent volume, I referred to ochrogaster. Sir George 

 Hampson refers the first name to Euxoa,y^\\\\. pleuritica Grt., as a syno- 

 nym, and the second to tessellata Harr. There is no doubt that I 

 mixed the two insignala in my original notes and that the first de- 

 scribed form which I referred to insulsa is the one that should have 

 been referred to ochrogaster. The type is a very faded uniformly 

 colored exanlple nearly like the cinereoniaculata of Morrison and has 

 nothing to do with pleuritica. It is a form of ochrogaster without 

 reasonable doubt. On the other hand that insignata which I referred 

 to insulsa is correctly placed by Hampson with tessellata and to that 

 extent my catalogue must be corrected. The synonymy will stand, 

 then, Agrotis insignata Wlk.= Euxoa ochrogaster On.: Agrotis illata 

 Wlk.= insignata Wlk., = E. tessellata Harr. 



Euxoa tristicula Morr. = silens Grt. This reference appears in 

 my latest check list, but the synonymy was developed in the course of 

 a correspondence between Sir George Hampson and the Brooklyn In- 

 stitute, and both parties notified me of the conclusion reached. I 

 have since verified it, by an examination of Mr. Morrison's type 

 which is less distinctly marked than usual and does not at first suggest 

 Mr. Grote's species. No one who compared Hampson's Fig. 20,
