FAMILY XXIX. PHOEID.E. 



PHORIDJE, Hal. D. B. I. 9 (1851). 



This family has been divided into the four following genera : 

 Phora, Conicera, Metopina, and Gymnophora ; the three latter are 

 here reunited to Phora. Conicera is distinguished by the arista 

 of the male, which is vertical and thick towards the base, Meto- 

 pina by its much compressed thorax, and Gymnophora by the bare 

 costal vein.
