914 PROCEEDINGR OF THE NATIONAL MUSEUM. vol. xxv. 



poor but recognizable condition, labeled by Chambers insequepulvella, 

 and proving- beyond a doubt that it really is Miss Murtfeldt's species. 



In Amherst, in Professor Fernald's collection, I have examined Miss 

 Murtfeldt's type, and I have also received identical authenticated 

 specimens from Miss Murtfeldt. 



In the U. S. National Museum are, besides these, two identical 

 specimens bred b}" Mr. Coquillet in Los Angeles, California, from the 

 same food plant as Miss Murtfeldt recorded, Amhrofiia a7'timis! folia. 

 Mr. Coquillet has kindly given me his notes on the larva, which are 

 identical with Miss Murtfeldt's careful description. 1 have also bred 

 the species from same food-plant in Washington and in Kentucky. 



TRICHOTAPHE LACTIFLOSELLA Chambers. 



Gelechia lactlflosella Ciiambeks, Eull. U. S. Geol. Surv., IV, 1878, pp. 89, 144. — 



RiLEV, Smith's List Lep. Bor. Am., No. 5398, 1891. 

 Trichoinphe lactlflosella Busck, Dyar's List Amer. Lep., No. 5668, 1902. 



The unique type of this easily recognized, large, light-yellow species 

 WIS found in the Museum of (comparative Zoology in Cambridge, 

 in good condition, authenticated b}^ Chambers' label and agreeing 

 with his description. 



I have taken several specimens of this species this sunmier at light 

 on Plummers Island in the Potomac River, Maryland. 



The type is from Texas. 



TRICHOTAPHE TRIMACULELLA Chambers. 



Gelechia triiiiaculellu Chambers, Can. Ent., VI, 1874, p. 238; Bull. U. S. Geol. 

 Surv., IV, 1878, p. 147.— Eiley, Smith's List Lep. Bor. Am., No. 5500, 1891. 

 Trichotaphe trimaculella Busck, Dyar's List Amer. Lep., No. 5669, 1902. 



Chambers' type from Miss Murtfeldt's collection, now in Professor 

 Fernald's possession, agrees with his types in Cambridge and with his 

 description. 



It is an easily recognized species, of which I have found examples 

 in the unnamed material in the U. S. National Museum. 



It is a t3'pical Trichotaphe and has a similar ver}^ striking counter- 

 part in Ypsolophus tonceyellas Busck {Anarsia trimaculella Chambers) 

 (p. l>i!2), as Tric}iota2)he setosella has in Ypsolophus eupatorieUa (p. 925). 



This recurring specific similarity between species of the two genera 

 is an interesting proof of their near relationship. The species was 

 described from Kentucky; the specimen in the U. S. National Museum 

 came from Texas. I have also taken it at light in District of Columbia.
