lection, and Mr. Grote gave me types of each, which are now in the 

 National Museum. The genus lias little in common with those with 

 which it is associated; but 1 leave it where Mr. Grote put it until 

 critical study develops a better place for it.

 Mississippi A" alley; Colorado; Illinois in August; District of Columbia, 

 in July, August, ami September. 



Guenee's type is in the British Museum, and is unquestionably the 

 same as Mr. G rote's species. Walker's type I did not see, but Mr. 

 Grote did, and is -positive, in referring it to atriciliata. 1 made a re- 

 grettable error in identifying Nono<lcx tui<-i<-ol<ir Gn., with this species. 



P. aiigustiorata (Jit." 

 1X82. Grt., Bull. Ge..l. Surv., vi, 5X4, I'hihiNcntn. 



HABITAT. Colorado. 



Mr. Grote gave me a, specimen marked type, which is now in the 

 National Museum. 



Genus TAPINOSTOLA Led. 

 1857. Lederor, Noct. Eur., 123. 



T. variana Morr. 

 1X75. Morr., Proc. Ac. Nat. Sci. Phil., 1X75. .|:!2, TnpinoxtoJn. 



HABITAT. Detroit, Michigan. 



The type should be, and probably is, in the Museum of Comparative 

 Zoology at Cambridge; but I did not see it there. 



T. orientalis Grt. 

 1882. Grt., Bull. Geol. Surv., vi, 583, Tapinoslola. 



HABITAT. Kittery Point, Maine; Buffalo, New York. 



I have seen the type specimens in Dr. Thaxter's collection, and have 

 identified the species from Buffalo, New York. Dr. Thaxter thought it 

 probably a, variety of rayiantt. Mr. Netimu-gen also has a "type."
