of the head, particularly on the ventral surface. These, too, are dif- 

 ferently developed in the different species but no consideration is 

 given them here. 



While, as above remarked, variation occurs in the epistomal ap- 

 pendages of the species of mosquito larvae, those of a particular brood 

 are fairly constant.

 A NEW NAME FOR A TINEID GENUS. 



By August Busck, 



St. Louis, Mo. 

 Paraclemensia, new name. 



Brackenridgia Busck, Proc. Ent. Soc. Wash., V, 193, 1903, not Ulrich, Tr. Amer. 

 Micr. Soc, x.\iii, 90, 1902. 



Prof. T. D. A. Cockerell has kindly called my attention to the fact 

 that the name Brackenridgia used by me for the genus of which aceri- 

 foliella Fitch (Dyar, Cat. Am. Lep., No. 6477) is the type and at 

 present the only recognized species, is preoccupied in the Crustacea. 

 I am glad to adopt a suggestion from Prof. Cockerell and would sub- 

 stitute the new generic name Paraclemensia, thus retaining in the 

 name the tribute to the founder of the study of Microlepidoptera in 

 this country.
