DIPTERA. ~ 231 
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. 
Thése Insects are analogous to the Culices, and have been desig- 
nated by authors under the name of V%pulz culiciformes. 
Those, in which the antenne of both sexes consist of fourteen 
(somewhat) oval joints, the last differing but little from the pre- 
ceding ones, and where the wings are laid horizontally one over 
the other, compose the subgenus 
Coretura, Meig. 
Tipula culiciformis, De Geer, Insect., VI, xxii, 10,11. A brown 
body; legs and abdomen grey; nervures of the wings hairy(1). 
Those, in which the wings are inclined, and the antennz 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 
Curronomus, Meig. 
To which belongs the Tipule annulaire of the same author, 
Ibid., XIX, 14, 15, which is of a brownish-grey, with transverse 
black bands on the abdomen, and a black point on the wing(2). 
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 antennz of the females, almost globular; 
the last somewhat thicker than the preceding ones. To this sub- 
genus we refer the 
Tipule bigarree, Id., Ib., XXIV, 19, which is cinereous; 
whitish, spotted with blackish; antennz of the females terminat-
