120 THE CANADIAN ENTOMOLOGIST. 



Agrotis vetusta, Wlk., C B. M., Lep. Het. XXXIL, 691, 1865. 



This species is not represented in the material sent, and I am entirely 

 unable to apply the description to any form known to me, either in the 

 agrotids or in the noctuids as a whole. According to Dr. Bethune's state- 

 ments the type,, mentioned by Walker as in his collection, has no present 

 existence, and as the description cannot be satisfactorily applied, the name 

 must drop. I have reprinted the description in my Revision of the 

 Agrotids, p. 212. 



Walker has described under the specific name vetusta an Agrotis, a 

 Maviestra and a Mythiirma. It was Mythimna vetusta which Mr. Grote 

 suggested might be his niurcenida, not the Agrotis as I erroneously sug- 

 gested in my transcript, nor the Mamestra as Mr. Grote stated in the 

 last number of the Can. Ent. 



Agrotis inextricata, Wlk. 



A specimen of Carneades messoria, Harris, is so labelled in Walker's 

 handwriting, but I cannot find any description of the species under that 

 genus. Walker does, however, describe a Mamestra inextricata (C. B. 

 M., Lep. Het, XXXH., 658, 1865), and as the description applies well 

 enough and the specimen is said to be in Dr. Bethune's collection, it may 

 be accepted as type, and cited as a synonym to Carneades messoria. 



Agrotis ijidirecta, Wlk., C. B. M., Lep. Het., XXXH., 659, 1865. 



In this case also the species is described under Maviestra, and the 

 species applies well to the specimen labelled Agrotis itidirecta in Walker's 

 handwriting. The specimen is Carneades messoria, making the fifth name 

 applied to this species in Dr. Bethune's material alone ! 



How many more of Walker's names can be applied to this species 

 when the types are studied, it is interesting to contemplate ? Thus far 

 no redescriptions of Carneades tessellata have been identified ; but it 

 seems scarcely possible that the species should not have been represented 

 in material received by the British Museum, and its variations must have 

 afforded full scope to Walker's peculiar genius. 



Hadena tenebrifera, Wlk., C. B. M., Lep. Het., XXXHL, 714, 1865. 



A male specimen in very fair condition is Semiophora catherina, Grt., 

 (Can. Ent., VI., 116, 1874, Matuta). The specimen bears Walker's 

 label, agrees with the description, and is unquestionably the type. The 

 species must be known in future as Semiophora tenebrifera, Wlk., and 

 Catherina, Grt., cited as a synonym.
