MAY FLIES AND MIDGES OP NEW YORK 125 



conical; in the female the antennae are pilose, the fifteenth 

 thicker than the others, pubescent and more acuminate. Thorax 

 elevated, with a depression in front of the scutellum, scutelliim 

 rather small; metathorax with a longitudinal furrow. Abdomen 

 composed of eight segments, long, hairy; more hairj and longer in 

 the male than in the female. Wings often pubescent, hairy along 

 the hind border, the subcostal vein ending beyond the middle of 

 the wing, vein R^ ending about two thirds the length ; vein Ro+s 

 emerging from the crossvein and the lower branch (R3) ending at 

 beyond three fourths the length; vein U^^- also proceeding from 

 the crossvein^ ending a very little in front of the tip; cubitus 

 forked as usual, the M-Cu crossvein present. Legs long and slen- 

 der, pubescent, unarmed; coxae of moderate size, claws very 

 small; in the male the fore tarsi are often pilose, in the female 

 always bare. 



The group T a n y p u s which is equivalent to the genus of 

 Meigen (1803) has been divided by Skuse (1889) into three 

 genera, Procladius, Isoplastus, and T a n y p u s 

 sens. str. Skuse proposed to retain the name Tanypus for 

 those species in which the wings are hairy and in which the 

 fork of the cubitus is proximad of the M-Cu crossvein. This 

 cannot well be maintained since Meigen (1803) gives c i n c t u s 

 Fabr. (=p u n c t i pen n.i s Meig.) as the type species, and it 

 possesses hairy wings and the fork of the cuilSitus distad of this 

 crossvein (i. e. petiolate). I therefore suggest retaining the name 

 Tanypus for the last-mentioned division and propose the 

 name of A b 1 a b e s m y i a for the former. Skuse has already 

 provided for the bare-winged species with the fork of the cubitus 

 petiolate the name Procladius. Isoplastus applies 

 to an Austi-alian genus. There remain still the species having 

 bare wings Avith fork of the cubitus proximad of crossvein, for 

 which I propose the name of Anatopynia. These new 

 genera will be more fully characterized farther on.
