visible appendages. Fore coxae yellow with black bristles at 

 tip : middle and hind coxae black ; legs yellow, tarsi only slightly 

 darker towards the tips ; middle tibiae with the usual bristle near 

 the base rather large; fore and middle femora with a few bristle- 

 like hairs near the tip on the lower outer edge ; pulvilli of the 

 fore tarsi distinctly enlarged. Tegulae and halters yellow, the 

 cilia of the former appears yellow in most lights, but in a certain 

 direction it appears nearly black. Wings hyaline ; first vein 

 scarcely reaching one third of the distance to the tip of the sec- 

 ond vein. 



Two females from the same location seem to belong here ; 

 they agree with the males in the color of the legs, cilia of the tegu- 

 lae, face and front, the two latter being of about equal width ; 

 the thorax is more blue-green and the abdomen pure green, the 

 venter being yellow but this color does not extend up on the sides 

 as in the male. Length 3 mm. 



Described from two males and two females labeled (Belize; 

 Johnson), in the collection of Prof. J. M. Aldrich and presented 

 to him by Charles Fuller Baker. Type in the collection of J. M. 

 Aldrich. 



Specimens of this species will be likely to be found with the 

 yellow of the venter extending more or less onto the dorsum as 

 it does sometimes in D. lamellatus Loew.
