NO. 1938. THE DIPTEROUS FAMILY PHORIDJE— M ALLOC H. 437 



Third antennal joint conical, gradually narrowing to a point, not thickly pubescent, 



and reaching to vertex or short of it 2. 



2. Second costal division one-half as long as first; wings brownish, neotropica, p. 437. 

 Second costal di\'ision one-third as long as first; wings clear atra, p. 437. 



CONICERA ALDRICHI Brues. 



Easily distinguished from the other species of the genus by the 

 peculiar third antennal joint, besides having four mid tibial spines — 

 two at basal thii'd, one at apical third, and one at just before apex. 



CONICERA NEOTROPICA Brues. 



Is very similar to atra but larger, the third anteimal joint is rather 

 broader, the fore tibia has only one distinct setula near the base and is 

 devoid of the row of serial setulose hairs, present in atra, beyond it 

 reaching near to apex, the tibial spines are longer and stronger than 

 in atra, especially those on the mid tibia, the costa extends nearer to 

 the wing middle, the first division being only twice as long as the 

 second, the costal frmge is much shorter and closer, having six 

 bristles from end of costa to end of first vein mstead of three to four, 

 as in atra; the abdomen is also a deep velvety black mstead of dull 

 black, and shows distinct narrow pale hind margins to the segments 

 which are not present in atra. 



Described as a variety of atra Meigen, by Brues. ^ Grenada, West 

 Indies. 



Type in U. S. National Museum collection. (Cat. No. 7756.) 



CONICERA ATRA Meigen. 



Common throughout Europe and evidently widely distributed 

 in Anierica. Known in the male sex from all other Phoridae except 

 the above species by its black color, conical third antennal joint, 

 apical arsita, and unforked third vein. 



Localities of specimens examined: District of Columbia, Boston 

 and Horse Neck Beach, Massachusetts; and Ithaca, New York. 



Genus PHORA Latreille. 



Phora 2 Latreille, Hist. Nat. Crust, et Ins., vol. 3, 1802, p. 464. 

 Trineura Meigen, 111. Mag., vol. 2, 1803, p. 276. 



I am adopting PJiora of Latreille for this genus because this name 

 has priority over Meigen's name by one year, and the same species 

 was cited as the type of both. 



Brues recognized the fact that Latreille's name had priority over 

 Meigen's, but did not adopt it because of the old established usage of 

 those names for different genera.^

2 Phora was first used by Ivatreille in 1796 (Pr6cis, p. 169), but no species was cited for it until 1802, which 

 must be considered as the date of its creation, instead of the earlier one.
