June, 1902.] BUSCK : NoRTH AMERICAN TlNEINA. 95 



bers' unique type was deposited in the Belanger collection, Univer- 

 site Laval, Quebec, Canada, and through the kindness of the present 

 curator, Rev. Dr. C. E. Dionne, I secured last year this together 

 with all others of Chambers' types found there, with his original labels 

 attached. It is now in the U. S. National Museum under the type 

 number 5768. Finally I have studied Lord Walsingham's type in the 

 collection of Professor Fernald and through his kindness secured for 

 the National Museum one specimen, identical with the type and from 

 the same locality, Orono, Maine. 



Without these good opportunities I hardly should have been able 

 to make out this synoynmy, but once it is known, it is easily substan- 

 tiated by the three careful descriptions. 



Besides the types I have seen other specimens from the following 

 localities : Pennsylvania, New York, Maine and eastern Canada. 



Babaiaxa, gen. nov. . (PI. XII, Fig. 4.) 



Type : Psecadia delliella Fernald. 



Antennre three fourths, simple, slightly pubescent, basal joint without pecten. 

 Labial palpi slender, smooth, curved, reaching vertex, terminal joint pointed, half as 

 long as second joint. Tongue stout, basal part scaled ; face, head and thorax smooth. 

 Fore wings elongate, three times as long as broad, costal and dorsal edges nearly 

 straight, parallel, apex obtusely pointed. 12 veins, 7 and 8 stalked to costa, rest 

 separate, ib furcate at base. Hind wings as broad as fore wings, elongate-ovate ; 8 

 veins, vein 8 is connected at the end of the cell with 7 by an oblique cross vein and 

 basal part of vein 7 is obsolete, so that the upper side of the cell is formed not as 

 usual by the subcostal vein (7), but by the costal vein (8), and the cell thus actually 

 emits 7 veins ; veins 7 and 6 are parallel, 5 nearest to 6, 3 and 4 connate, inttrnal 

 veins [folds] to below 7 and to 6. Hind tibiae rough-haired above, middle and 

 terminal spurs well developed. 



The very peculiar venation of the hind wing is, so far as I know, 

 unique in the Tineina, to which group this genus surely belongs, and 

 does not conform with the present definitions of any of the families, 

 except it be the Gelechiid?s. 



I am quite uncertain about the true relationship of this form and 

 record its characters mainly in order to learn the opinions of other 

 workers.

I have examined the type of this striking species in Professor 

 Fernald' s collection. The U. S. National Museum possesses speci-
