his genus Limnophila without discal cell is not explained in his 

 paper and I am not aware of the existence of any such species." 



Consequently, the species in the New World, as well as the Old, 

 should be known as Limnophila, but it would be better to accept 

 the prior name Petaurista (Meigen, 1800) as the tribal name, i. e., 

 Petauristini instead of Limnophilini. 



There are a few corrections in synonymy to be made. Tipula 

 costalis. Say of the Eastern United States (Jour. Acad. Nat. Sci. 

 Philadelphia, III, 23.2, 1823) is preoccupied by Macromastix cos- 

 talis, Swed. of Australia. {Tipula costalis, Swederus; Act. Holm, 

 286, 1787.) No other name seems to have been applied to the 

 costalis of Say, and I propose the name Tipula sayi, nom. nov. 

 (non Oropeza sayi, Johns). Dicranomyia brunnea, Grimshaw, of 

 Hawaii (Fauna Hawaiiensis, HI, 1901) is preoccupied by D. 

 brunnea Doane (Eastern United States) (Jour. New York Ent. 

 Soc. VIII, 1900) and its describer should propose a new name for 

 the Hawaiian insect. In the "Type-species of Am. Dipt.," the 

 late Mr. D. W. Coquillet states that the type of Holorusia, Loew, 

 is grandis, Bergr. Bergroth (Ent. Tidskr, IX, 1888) proposed 

 the name grandis to replace rubiginosa, preoc, on the grounds 

 that Holorusia is not distinct from Tipula. If the genus Hol- 

 orusia is to be considered as distinct as is done by Mr. Coquillet, 

 the type is still rubiginosa, Loew, and not grandis, Bergr. 



Descriptions of New Species, 



In the description of the following species of crane-flies, I have 

 adopted many of the suggestions proposed by Mr. R. A. Mutt- 

 kowski in his splendid article "The Composition of Taxonomic 

 Papers." (Ann. Ent. Soc. Amer., June, 1911; Vol. II, No. 2, pp. 

 194-217). Concerning the thoracic structure, the terminology given 

 by Mr. R. E. Snodgrass, "The Thorax of Insects and the Articu- 

 lation of the Wings" (Proc. U. S. Nat. Mus., XXXVI, pp. 568, 569; 

 pi. 62; figs. 173, 174; pi. 63, figs. 175-178) is largely used. The 

 best paper on crane-fly genitalia, is, without question, that by 

 Mr. Snodgrass on "The Hypopygium of Tipulidcp." (Trans. Am. 

 Ent. Soc, XXX, June, 1904; pp. 179-236, pi. VIII, XVIII.) The 

 terminology used therein has been adopted in the present paper.
