SOME MOTHS, GENUS ACLERIS — OBRAZTSOV 247 



of the American Museum of Natural History that should be treated 

 as lectoparatypes, and selected the lectotype. The present author 

 concurs with this proposal of Klots. 



Types. — ^Lectotype (selected by KJots, 1942), male, Hampton, N.H., 

 Oct. 27, 1908 (S. A. Shaw); nine paratypes, the above locality, and 

 Montclair, N.J., Feb. 1, 1903 (W. D. Kearfott). The entire type 

 series in AMNH. 



Other specimens examined. — Six specimens (paratypes of roh- 

 insoniana), Hampton, N.H. (S. A. Shaw), AMNH.

In the original description of this species, Kearfott indicated as its 

 type a specimen in the U.S. National Museum ("type no. 7784"). The 

 specimen in the American Museum of Natural History, selected for a 

 lectotype (Klots, 1942), is, therefore, merely a paratype. An ex- 

 amination of the male genitalia of britannia has showed that they 

 differ a little from those of McDunnough's (1943) figure in having the 

 sacculus before its emargination more acute and the subapical spine 

 of the aedoeagus somewhat longer. The number of cornuti in this 

 species probably varies because in one male there are only tlii-ee cornuti 

 instead of four arranged in two pairs. The female genitaha of bri- 

 tannia are quite accurately figm-ed by McDunnough. 



Types. — Holotype ("type no. 7784"), male (genitalia on slide, 

 prepared by A. Busck, Apr. 21, 1935), Kaslo, British Columbia 

 (Dyar, no. 39083); paratype, female (genitalia on the same slide), 

 same data (Dyar, no. 27985) ; both in USNM. Paratype ("lectotype" 

 of Klots, 1942), female (genitalia on slide 206-Obr.; this specimen 

 was listed by Klots, 1942, as male), same data (N. Griddle; Dyar, no. 

 21082), AMNH. 



Remarks. — Besides the nominate form redescribed by McDun- 

 nough (1934), the present author examined two individual forms of 

 britannia, very striking and looking like two separate species, but in 

 the genitalia not differing from britaniiia. Pending a revision of the 

 variation of this species, these two forms are described below without 

 names.
