OF WASHINGTON. 193 



Lord Walsingham examined this type in 1872, and from his 

 recollection and notes on it, concluded that his Lampronia 

 tripunctella was a synonym. He has also made Eudarcia 

 simulatricella Clemens synonymous with Tinea ccemitariella 

 Chambers. I have examined types of both these latter species 

 and they are undoubtedly congeneric, but just as surely specifi 

 cally distinct. The former is evidently Walsingham's Lam 

 pronia tripunctella , agreeing in all particulars with his descrip 

 tion and figure. The latter agrees well with Clemens' decription 

 of russatella, but could not be Walsingham's species, lacking as 

 it does the white apical cilia found in tripunctella and also in 

 Clemens' type of simulatricella^ though not mentioned by 

 Clemens. t\ russatella should then be known as Eudarcia 

 russatella Clemens 



A specimen collected by the writer in Kentucky, and Cham 

 bers' type of ccemitariella [No. 412] are in the U. S. National 

 Museum. 



Incurvaria (Ornix) acerifoliella Fitch. 



The specimen of this species received by Clemens from Fitch 

 is found under Clemens' No. 40. The right wings are missing ; 

 alar exp., 1 1.5 mm. 



This agrees with our present conception of the species, speci 

 mens of which are in the U. S. National Museum. Lord Wal 

 singham has shown the synonymy of Tinea iridella Chambers 

 with this species. The species falls, according to the venation, 

 intermediate between the genera Incurvaria and Eudarcia, 

 though it cannot rightfully be placed in either genus, as already 

 shown by Clemens. 



I propose the name Brackenridgia, for the genus of which 

 acerifoliella is type and which has the following very distinct 

 venation : 



Fore wings n veins, vein 4 absent, all separate, 7 to costa, \b furcate at 

 base. Hind wings as broad as fore wings, 8 veins, veins 5 and 6 stalked, 

 rest separate, vein 6 to apex. The oral characters are as in Incurvaria. 



No other species is at present known to the writer. 



It is in this connection well to draw attention to the fact that 

 probably only two out of the ten American species hitherto placed 

 in Incurvaria truly belong in this genus, namely Incurvaria. 

 cenescens Walsingham and Incurvaria politella Walsingham. 

 Besides these, labradoriella Clemens* may profitably be left in 

 the genus for the present until more material is obtained, though 

 the appearance of the incomplete type, Clemens' No. 215,* does 

 not suggest that genus as Clemens also noted. 



The same is the case with mediostriatella Clemens,* which
