MAY FLIES AND MIDGES OP NEW YORK 125 



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

 thicker than the others, puibescent and more acuminate. Thorax 

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

 rather small; metathorax Avith a longitudinal furrow. Abdomen 

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

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

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

 the wing, vein R^ ending about two thirds the length ; vein R2+3 

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

 beyond three fourths the length; vein R^j.^ also proceeding from 

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

 forked as usual, the M-Ou 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 T a n y p u s 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. (=pu n c t i pen n i s Meig.) as the type species, and it 

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

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

 T a n y p u s for the last-mentioned division and propose the 

 name of Ablabesmyia 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 Australian genius. There remiain still the species having 

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

 which I propose the name of A n a t o p y n i a . These new 

 genera will be more fully characterized farther on.
