MAY FLIES AND MIDGES OF NEW YORK.. BULLETIN 86, NEW YORK STATE MUSEUM. 
This interesting and important work, which constitutes the third report on 
the aquatic insects of New York State, contains 352 pages and 37 plates. Pro- 
fessor James G. Needham gives an interesting account on the summer food of 
the bullfrog, followed by systematic notes on the Hemerobiidae and the 
Ephemeridae, with keys to the genera and descriptions of six ■ new species and 
one new genus Drunella. The family Hydroptilidae is treated by Mr. Kenneth 
J. Morton; one new genus {Neotrichia) and twelve new species being described. 
'I’he greater portion of the report is by Mr O. A. Johannsen on the Nema- 
tocerous Diptera comprising the family Chironomidae. This is the first Ameri- 
can publication of a monographic character bearing on this large and important 
family, and the degree of thoroughness with which the author has accomplished 
this work calls for great praise. The Chironomid genera of the world are 
defined, and all the North American species tabulated and described, together 
with many of the larvae and pupae, except the group Cerafopogon which is only 
generically treated. 
Some idea of the amount of work involved can be gained from the follow- 
ing figures: upwards of 50 genera and over 200 species are described, including 
two new genera {A?iafopyfiia and Ablabes))iyia) and 58 new species, or species that 
are not recorded in .\ldrich’s Catalogue. The genus Tanypus oi authors is divided 
into three genera, Procladius, Ab/abesmyia and Tanypus. The group Ceralopo- 
goft now comprises the genera Cerafopogon, Culicoides, Oecacfa, Bezzia, Ceratolo- 
p/iHS and Pa/po?nyia, the latter being divided into a number of subgenera includ- 
ing Heteromyia Say.
