preceding species more nearly than it does any of the American 
forms. Both European species have a smaller second posterior cell 
than any of ours, and the length and slenderness of the fourth pos- 
terior cell is much greater. 
Finally, to specify a few minor instances of little present value, 
SERRES (Géogn. terr. tert., 1829) states that a fossil fly of the genus 
Nephrotoma, allied to the European JV. dorsalis, occurs in the beds 
at Aix, Provence, and credits to the same beds a species of 
Trichocera.—Hore mentions a Tipula from Aix (Zrans. Entom. 
Soc. Lond., iv, 253, 1847) which he compares with 7. rzvosa. I 
do not know what that species may be. Herr has also named 
a species from the same place, Zipula infernaits, but it is unde- 
scribed.—WoopwarbD, in a list of insect remains from the Isle of 
Wight (Quart. Journ. Geol. Soc. Lond., xxxv, 344, 1879) gives 
among others ‘‘ Tipulide, 6’’ specimens.—SCHOBERLIN (Soc. 
Entom., iii, 69, 1888) mentions the occurrence of aspecies of Tipula 
at Oeningen, Baden, which he compares to 7. ochracea, a true 
Tipula.—BELL, in the Lx/omologist (xxi, 1888) in an article on 
glacial insects, mentions a ‘‘ Diczra, allied to Tipula,’’ as found in 
a ‘fcrannoge’’ in Wigtonshire, England, presumably in the 
refuse of lake-dwellings. Apparently he must have meant some- 
thing akin to Dictenidea or Ctenophora, but closer reference 
is impossible ; it is perhaps hardly fair to class it at all among fossil 
insects, and it is accordingly not alluded to in the tabular lists in 
this paper.—Lastly, KLeps, in his Ca/alogue of the Stantien and 
Becker bernstein-museum (1889), on p. 65, lists a specimen (No. 
478) ‘‘in the vicinity of Tipula, a new species with striking 
antenne.”’ 
These data are all summarized in the following list, in which the 
species which are known purely by name, without description 
or figure, are prefixed by an asterisk.
