THE CANADIAN ENTOMOLOGIST. 119 



before me, and does not apply well to any form of messoria known to me. 

 As the type is in existence, the best way will be to cite insulsa, Wlk., as 

 a questionable synonym of ducta, Grt., and thus call the attention of who- 

 ever may have a chance to make the comparisons to the probabilities. 

 The species was described from Orillia, West Canada, and the locality is 

 therefore in favor of the name. 



Mamestra displic'mis, Wlk., C. B. M., Lep. Het., XXXII., 660, 1865. 



The specimen is labelled by Walker, and is evidently the type. It is 

 a normally marked Carneades messoria. 



Mamestra tmicolor, Wlk., C. B, M., Lep. -Het., IX., 233, 1856. 



Determined by Walker, but not the type. It is Noctua clandestina, 

 Harris, and therefore agrees with the type, which Messrs. Grote and 

 Robinson have also identified with clandestina. 



Mamestra nigriceps, Wlk., C. B. M., Lep. Het.. XXXII. , 659, 1865. 



Apparently the type, agreeing well with the description, but without 

 Walker's written label. A printed label has been substituted for the 

 original, if a written one ever existed. 



This species is also equal to Noctua clandestina, Harr. It was 

 described as in Dr. Bethune's collection. 



Mamestra cotitetita, Wlk., C. B M., Lep. Het., IX., 232, 1856. 



A badly rubbed specimen, but easily recognizable as Haaena devas- 

 tatrix, Brace, and therefore like the type which Mr. Grote has referred in 

 the same way. 



Agrotis reticens, Wlk., C B. M., Lep. Het., XXXII, 692, 1865. 



Two specimens, one with Walker's written label, the other with a 

 printed " Type " label and a printed specific label. Both specimens are 

 Carneades tnessoria, Harris. 



Agrotis ordinata, Wlk., C. B. M., Lep. Het, XXXII., 691, 1865. 



The specimen bears Walker's written label, and is described as in Dr. 

 Bethune's collection ; but it does not at all agree with the description. 

 Neither does it agree with the description of any other of the species 

 described from Dr, Bethune's collection. The specimen is Pyrophila 

 tragopogonis, Linn., and I can only imagine that Walker in placing his 

 labels, -placed this one on the wrong specimen, or that in the transferring 

 in Dr. Bethune's collection, another specimen became substituted for the 

 type. What is described is really a form of Carneades messoria, Harr., to 

 which I would cite ordinata as a synonym.
