228 PROCEEDINGS OF THE NATIONAL MUSEUM vol. ii4 



semicircular with caudal flaps turned cephalad. Antrum a moderate 

 plate. Ductus bursae with a broad sclerotized girdle remote from 

 antrum, forming together with cervix bursae a rather broad tube. 

 Corpus bursae elongate; signum semistellate. 



Remarks. — The number of cornuti is the same as in semiannula or 

 implexana, but instead of a sclerotized plate, a coniform apical cornutus 

 is present. The female genitalia are rather similar to those of im- 

 plexana, especially the shape of sterigma, but the ductus bursae have a 

 sclerotization forming a complete girdle, and the signum is semi- 

 stellate. 



Type. — Lectotype (selected by the present author), female (genitalia 

 on slide, prepared by A. Busck, Sept. 7, 1924), Amherst, Mass., 

 USNM. 



Other specimens examined. — Two males (genitalia on slides, pre- 

 pared by A. Busck, Apr. 6 and Sept. 14, 1924), Wliitesbog, N.J., 

 July 7 and Oct. 30, 1916 (H. B. Scammel); one female (genitalia on 

 slide, prepared by A. Busck, Sept. 10, 1924), Pennsylvania. All the 

 above specimens in USNM.
