will show, are very important. Perlmeata flies very early, and is short- 

 lived. The West Virginia types (co-types we would call them now) in 

 April. I have it from New Brighton, Pa., April 13-May 5. In this 

 locality I take it from April 21-May 2. The Albany types May 4. Last 

 year I went to the Catskill Mts. , fifty miles from Albmy, on May 23, 

 hoping to take it there. I saw none, and rashly published tiie statement 

 that it was not found there. This year I went on May 2nd, and found it 

 flying, taking up to May 14 some 17 specimens, after that only one worn- 

 out $ on May 20, though I searched diligently. 



ExJuimata did not make its appearance until two weeks later, June 

 4, its usual time as shown by my dates of the past ten years, and was 

 common until the second week of July- Now, eliminating from the group 

 those from Brooklyn, N. Y. (Graef), as without date, the above reord ^viU 

 show, with the exception of those from Mt. Washington, N. H., July 

 (Morrison), they were, including the Albany types, all examples of 

 perlineata, while the date (July) tells plainly that those from New Hamp- 

 shire were as surely exlmmata. These last were figured on plate, as Mr. 

 Taylor points out, and if the statement that for thirty years we have given 

 to this species the name oi perlifieata has any force, which it has not, I 

 would point out that Dr. Packard committed an error precisely similar in 

 the case of Caripeia angustiorata, recently published by Mr. Svvett 

 (Journal N. Y. Ent. Soc, Vol. 14, page 128). 



Descriptions I do not underestimate, I trust, and in this case I have 

 examples oi perlineata which answer well to it. If we are to be allowed 

 to arbitrarily set aside the types or co-types upon which an author bases 

 his description, as Mr. Taylor has done, it must be, in my judgment, for 

 better reasons than exist in this case. 



Hence, I hold to my conviction that 12-lineata having "gone west," 

 where it rightly belongs, i\\dii perlineata, as represented by the co-types in 

 the Packard collection, is the comptaria of Walker, and that exhianata is 

 to remain a valid species. 



Note. — Since writing the above the thought occurred to me that 

 perhaps the original types oi perlineata had been returned to Dr. Lintner. 

 I addressed a query to Dr. E. P. Felt, State Entom., and his reply, " The 

 types oi Larentia perlineata. Pack., are in the Lintner collection, and in 

 excellent condition," caused me to journey to Albany to inspect them. 

 The types are the same with those in the Packard coll. from West Va.
