66 ENTOMOLOGICAL NEWS. [Feb., '12 



Fulton County (New York), Tipulidae (Dipt.). II. 



By CHAS. P. ALEXANDER, Cornell Univ., Ithaca, N. Y. 



This is a continuation of the list in ENTOMOLOGICAL NEWS, 

 June, 1910. Since the publication of that article, much of the 

 undetermined 1909 collection has been worked over and an im- 

 mense amount of new material collected. The total number 

 of species definitely known from the county to date is about 

 125, which is more than is known from most States of the 

 Union. 



A few errors in the first part, most of which must be 

 charged against the author, should be corrected : On page 248, 

 thirteenth line in under 2, should read, "for several hundred 

 feet." The altitude of the island is 750 feet (average), not 

 875 feet. On page 251, Trichoccra crumalis should be T. 

 brumalis. 



New collecting grounds: Some of the new localities visited 

 proved to have an extremely rich Tipulid fauna. The more 

 notable of these are : 



"Psocid Glen," on the west bank of the Cayudutta creek, 

 between Johnstown and Sammonsville ; a small creek flowing 

 into the Cayudutta at the electric-light dam. Although at a 

 low altitude (550 feet), the fauna is distinctly Canadian. 



"Prairie Lake Bog" in Caroga Township (1,870 feet); a 

 bog in the tertiary stage, supporting a perfectly normal oxy- 

 lophytic type of vegetation, such as : Solidago uliginosa, Gcn- 

 tiana linearis, Acer pennsylvanicum, A. rubrum, A. spicatum 

 Nemopanthns mucronata, Kalmia angustifolia, Andromeda 

 polifolia, Chamaedaphne calyculata, Chiogcncs liispidnla, J'ac- 

 cinium macrocarpon, Aronia melanocarpa, Sanacenia pui'pu- 

 rea. Drosera rotundifolia, D. intermedia, Myrica gale, and a 

 variety of sedges. 



Since the publication of the first part, the acceptance of 

 Meigen's 1800 paper by most Dipterologists has changed many 

 of the genera used in trie Tipulidae. The names are given in 

 Coquillett's "Type-Species of North American Diptera," but 

 are widely scattered amongst the other genera of flies, so that
