144 The Ottawa Naturalist. [Oct. 



Pyrausta fumalis Gn. Sept. 3rd. 



Scoparia basalts Wlk. Very abundant ; observed at light every 

 evening. 



Crambus leachellus Zincken. Sept. 2nd, 5th, 15th. 



Crambus prafectellus Zincken. Sept. 4th, 5th, 15th, 16th. 



Crambus vulgivagellus Clem. Sept. 8th. 



Crambus trisectus Walk. Sept. 2nd, 8th. 



Thaumatopsis gibsonella Kearf. MS. Sept. 2nd, 3rd, 4th, 15th. 

 This pyralid was very abundant and specimens could have 

 been taken at light almost every evening. The species was 

 submitted to Mr. Kearfott, who pronounced it new, and it 

 has been described under the above name. Co-types are in 

 the collection of the Division of Entomology at the Central 

 Experimental Farm. 



Eucosma conftuana Kearf. Sept. 8th, 16th. Mr. Kearfott says 

 the species is common throughout the Eastern States, and 

 that in Ontario it has been taken at Trenton (Aug 24) bv 

 Mr. J. D. Evans. 



Aclerisniyisellana Walsm. Sept. 7th. According to Mr. Kearfott, 

 this is a common northern species, ranging from Eastern 

 Canada to the Pacific slope, and down to the Rocky Mount- 

 ains into Nevada. 



Aristotelia roseosuffusella Clemens. Sept. 8th. 



Machimia tentorijerella Clemens. Sept. 8th. An eastern species 

 some years abundant in autumn. It has been taken at 

 Toronto in September by Mr. H. S. Saunders. Mr. Kearfott 

 tells us that the larvae make a web on the underside of the 

 leaves of mostly all of our hardwood trees. 



Depressaria lythrella Walsm. Sept. 7th. Mr. Kearfott reporting 

 on this specimen says: "Walsingham bred this from larvae 

 on Lyihrum alatum, in Illinois. Nothing but the type 

 specimens were known until Beutenmuller sent me larvae 

 from the Black Mountains of North Carolina several years 

 ago, on a plant which I believe to be the above species. 

 Your specimen matches those bred from Beutenmuller 's 

 material, making the third locality so far known. If the 

 above plant occurs in the neighborhood of Rostrevor, I have 

 no doubt my determination is correct." Dr. Fletcher tells 

 me that Lythrum alatum is not recorded from so far north in 

 Ontario, but that Lythrum salicaria might be there and the 

 closely allied Nescea verticillata almost certainly is. 



Collecting in the above locality in June or July, would, I feel 

 sure, be most satisfactory. Mr. Dinsmore, the proprietor, told 

 me that earHer in the season great numbers of insects are at- 

 tracted to the acetylene lights on the verandah.
