Order Diptera. Fam. Tipulidae. 



Type of the Genus, Peronecera fuscipennis Curt. 

 Peronecera Curt. — Anisomera Curt. 



Antenna inserted in the middle of the face, not so long as the 

 thorax in the male (3), somewhat filiform, pilose and 7-jointed, 

 basal joint rather stout and obovate, 2nd small and cup-shaped, 

 3rd long, the 3 following shorter, nearly of equal length, 7th 

 small and ovate : shorter and 8-jointed in the female (3 $ ), the 

 5th joint short, the 3 following forming an ovate mass. 

 Labrum very short and trigonate. 



Palpi short, pubescent, incurved and 4-jointed, basal joint a 



little elongated, 2nd stouter and subovate, 3rd obtrigonate, 4th 



as long as the 1st, rounded at the apex (/). 



Labium short, broad, bilobed and externally pilose (g). 



Head small, bent under the thorax, the forehead produced and forming 



a tubercle (2 (^) .- eyes lateral ovate : ocelli none. Thorax ovate : 



scutellum semiorbicular. Abdomen sublinear, recurved at the apex, 



which is furnished with 2 large globose horizontal lobes in the male ; 



acuminated in the female with 2 vertical appendages (7 $ ). Wings 



longer than the body, parallel, and incumbent in repose, with 3 sub- 



marginal cells, the \st very long, 3rd elongate-trigonate : halteres 



capitate. Legs moderate, hinder the longest, simple ; tibiae with a 



very minute spine at the apex of each : tarsi shorter than the tibia, 



5-jointed, basal Joint the longest, 4th small: claws and pulvilli

In the Cabinets of Mr. Dale and the Author. 



Meigen having united Nematocera and Anisomera in his 

 Supplement, it is probable he would also include our species 

 with them, but as he, as well as Macquart, characterizes his 

 group as having 6-jointed antennae, it would not be advisable 

 to form one genus of the whole ; and unless there be indivi- 

 duals with modified antennai, connecting the long- with the 

 short-horned species of Anisomera, one would judge from 

 Meigen's figures that the species ought at least to be formed
