39 Diaphorus mundus Loevv. 



Diaphorus mundus Loew, Neue Beitr., viii, p. 57; Mon. N. 

 A. Diptera, ii, p. 161. 



Male : Length 3 mm. Eyes contiguous on the front ; an- 

 tennae yellowish with the third joint small ; arista nearly apical. 

 Thorax and abdomen light metallic green, the former with thick 

 ochre yellow dust. Coxae and feet yellow ; pulvilli of fore and 

 middle tarsi considerably enlarged. Halters and tegulae yellow, 

 the latter with black cilia. Wings grayish hyaline. 



Type location Pa.; X. J. (Smith Cat.) ; Charlotte Harbor, 

 Fla., (Johnson) ; Drayton, Idaho (Aldrich Cat.) ; I found this the 

 most abundant species of the genus at Bradentown, Fla., in 

 March, 1913, taking twenty specimens during the month. 



40 Diaphorus deceptivus Aid. 



Diaphorus deceptivus Aldrich, Biologia, Diptera i, p. 346. 



Male: Length 2.7-3 mm. Eyes narrowly contiguous on the 

 front ; arista almost apical ; face blackish ; antennae small, black. 

 Thorax globose, bright green ; abdomen dark golden green, apical 

 bristles scarcely perceptible ; hypopygium very small. Legs 

 yellow; middle and hind coxae infuscated for half their length; 

 fore pulvilli rather large, hind ones smallest ; tarsi scarcely infus- 

 cated towards their tips. Halters yellow ; tegulae infuscated, 

 their cilia blackish but appearing yellowish in certain lights. 

 Wings yellowish.

Prof. Aldrich says in the Biologia "D. deceptivus seems to be 

 related to D. subsejunctus, Loew, of Cuba; but differs in having 

 the front of the male obliterated by the contiguity of the eyes, 

 the cilia of the tegulae darker and the posterior tarsi more infus- 

 cated." He was somewhat doubtful of the validity of his species, 

 but only a comparison of a series of both species would establish 

 their identity ; until such a comparison can be made they must be 

 considered distinct.
