DIPTERA. 319 
dages at the posterior extremity of their body, resembling strings or 
arms; Reaumur calls them vers polypes. Their usual colour is red. 
The nymphs inhabit the same element, and respire by means of two 
exterior tubes, situated at the anterior extremity of the body. Some 
of them possess the faculty of swimming. 
These Insects are analogous to the Culices, and have been desig- 
nated by authors under the name of Tipule euliciformes. 
Those in which the antenne of both sexes consist of fourteen 
(somewhat) oval joints, the last differing but little from the preced- 
ing ones, and where the wings are laid horizontally one over the 
other, compose the subgenus 
Corretura, Meigq. 
_ Tipula culiciformis, De Geer, Insect., VI, xxii, 10, 11. A 
brown body; legs and abdomen grey; nervures of the wings 
hairy *. 
Those in which the wings are inclined, and the antennee are formed 
of thirteen joints in the males and six in the females, furnished with 
short hairs, and the last, as in the preceding sex, very long, consti- 
tute the subgenus 
Curronomvs, Merq. 
To which belongs the Tipule annulaire of the same author, 
Ibid., XTX, 14, 15, which is of a brownish-grey, with transverse 
black bands on the abdomen, and a black point on the wing +. 
Tanypus, Meig., 
Where the wings are also pendent; but the antennz consist of four- 
teen joints in both sexes, the penultimate very long in the males; all 
the others, like those of the antennze of the females, almost globular ; 
the last somewhat thicker than the preceding ones. To this sub- 
genus we refer the 
Tipule bigarree, Id., 1b., XXIV, 19, which is cinereous; 
whitish, spotted with blackish; antennz of the females termi- 
nating inabutton. The larva of the latter sex has four false feet, 
two near the head, and the rest at the posterior extremity of the 
body t. 
Sometimes the antenne, always composed of at least thirteen joints 
in both sexes, and for the most part grancse, are merely furnished 
with short setee, or at most, and in the males only, with a bundle of 
hairs at base. They form our Tzpules gallicoles.

base. .
