Notes upon certain Pyralidae. 



By Geo. D. Hulst. 



In the Transactions of the American Entomol. Society, Vol. XIII. 

 pp. 145-168, I published under the title "Descriptions of new species 

 of Pyralidce", 89 species in that family. The descriptions were in many 

 cases based upon single specimens, and in a few cases upon very indif- 

 ferent material. Moreover at that time a very large portion of the material 

 was the property of other persons, so that I was unable to make the 

 examinations generally necessary for determination. I also fell into an 

 unfortunate misinterpretation of some statements of opinion by one. 

 whose judgment was by me so highly regarded that I did not consider it 

 necessary to verify it, and this led to more than one error. Almost as 

 soon as the descriptions were published, I became the possessor of the 

 types of nearly all my species. I was thus able to give more complete, 

 study, and with further comparisons I became convinced that I had re- 

 described a number of species. I withheld the publishing of these till 

 I could make still further comparisons, which, upon a recent visit to 

 Prof. Fernald, I \tas able to do. I took all the types in my possession. 

 with me, and together we went over them, and compared them with his 

 material. He verified in the greater part my own conclusions, and 

 through his superior knowledge, pointed out errors that had escaped me. 

 As a result of our mutual study, I note the following : 



Chalazia gemmalis = Choreutes bjerkandella, Thun. 



Botis monulalis = B. mustilinealis, Pack. 



Botis pergilvalis = B. color adens is, Grt. 



Bolls gulosalis = B. magistralis Grt.
