THE CRANE-FLIIIS (TIPULIDAN) OF NEW ENGLAND:THIRD SUPPLEMENTARY LIST.
BY CHARLES P. ALEXANDER.

Trln basic list of Tipulidae for New England, as given in Mr.
Johnson's 'Diptera of New England' (Occas.Papers Boston Soc.
Nat. Hist. 7, no. 15: l*326, 1925) recordecl264 speciesof theseflies from the New England states. In two supplementary lists(Occas.Papers Boston Soc. Nat. Hist. 5 :169-174,7925, and ibid.
5:223-231,1927) I have added 26 speciesto this total, bringing
the list to 290 species. In recent years further collecting has
produced a considerable number of additional records rvhich are
given at this time ancl bring the list of Tipulidae to a total of 318.
In the present paper, I wish to record these additional forms, todiscuss in some detail the crane-fly fauna of Mount Mansfield,
highest of the Green Mountains, Vermont, and to describe threenovelties included in the list of additions to the list for Nerv
E ngland.

Wings narrower than in i,nconstans' Venation: Bs long-spurred at originl
radial field with adventitious crossveins,chiefly arranged in cell Br where theyvary in number from one to seven. Ninth tergite of the male hypopygium
narrowed outwardly, the caudal end conspicuously narrower than the base,the margin gently concave. In i'nconstans,the caudal margin of the tergite
is more deeply concaveand produced into small sublateral lobes, with a smaller
lateral incision on either side, the margin of the tergite fringed with delicate
set'ae.

Erioptera uliginosa is uncloubtedly a characteristic bog-inhabiting species, associ&ted in nature with other equally ch&racteristic bog forms as Phalacrocera tipuli.no O. S., Limonia(Dicranomgfia) u,liginosa Alexander, L. (D.) sphagnicola Alexand.er, Pseudoli.mnophilainornata (O. S.), Limnophila (Phylidorea)
platyphallus Alexander, Pilaria stanwoodae(Alexander) , P. aermontana Alexander
Erioptera ebenina Alexander. It wasformerly considered^nd.
that the sphagnum bogs in northeastern
North America supported a very restricted crane-fly fauna but
this is certa,inly not the case. Many of the bog speciesare local
and most species become more active at dusk, remaining concealed during the hours of bright sunlight.
Erioptera ul'iginoscr,has the knobs of the halteres darkened,in this respect agreeing most closely with Z. septemtrionis Osten
Sacken and E. ebenina Alexander. It differs from the former inthe strongly darkened wings and structure of the male hypopygium, as the simple inner dististyle; from ebenina it differs in theopaque mesonotum and very different hypopygial structure. In
its general appearance, especially the coloration of the body andwings, the new species more closely resembles E. uillosa Osten
Sacken, differing conspicuously in the darkened knobs of thehalteres and the structure of the male hypopygium.
