Two New Genera of Diptera. 



By D. W. CoQuiLETT. 



Hesperodes n. gen. Mycetophilidce. 



Near Hesperinus, but the third and fourth veins united for a short dis- 

 tance, crowding out the small cross vein, as in Platyura. Auxiliary vein 

 ending in the costa beyond the base of the third vein, subcostal cross 

 vein nearly midway between the humeral and base of the third vein, the 

 latter forked beyond the apex of the first vein ; fourth vein originating 

 irom the fifth near its base and just before the union With the third con- 

 nected by a cross vein with the upper branch of the fifth, forking a short 

 distance beyond the union with the third vein ; fifth vein forking midway 

 between the base of the third vein and its union with the fourth ; sixth 

 vein prolonged to the wing margin ; antennae about twice as Ibng as the 

 head and thorax united, cylindrical but tapering to the apex, 16-jointed, 



the first joint as broad as long, the second 

 twice as broad as long, and the others 

 twice as long as broad ; proboscis very 

 robust, shorter than height of head, palpi 

 Traginops irrorata. 4-jointed, eyes emarginate opposite the 



antenna?, ocelli wanting, abdomen slender, more than three times as long 



as the thorax. 



Type, the following species : 



Hesperodes johnsoni, n. sp. 



Reddish yellow, antennas and tarsi beyond the base changing to 

 brown, legs destitute of strong lateral bristles, tibial spurs well develop- 

 ed ; wings yellowish, becoming grayish hyaline on the posterior margin 

 and at the apex, a brown spot at apex of the first vein. 



Length 12 mm. 



Delaware Water Gap, N. J., a male specimen collected July 

 12, 1899, by Mr. C. W. Johnson, after whom the species is 

 named. Type No. 4391, U. S. Nat. Museum. 



Traginops n. gen. Agromyzidae. 



Apparently nearest related to Milichia. Occiput on its upper part 

 strongly produced forward in the middle, the middle of the front nearly 

 perpendicular, almost on a line with the face, the latter strongly produced 

 forward on its lower part, vibrisscC well developed, clypeus strongly
