NO. 1938. THE DIPTEROUS FAMILY PHORIDM—MALLOCH. 503 



Six males, Antigua, West Indies. MS. label ''attacking Solev/- 

 opsis geminata." 



The specimens are all males and what they would attack the ant 

 for I do not clearly understand. I hardly think this can be the male 

 of crawfordi and am describing it under this name in the belief that 

 it is distinct from that species, the male of which is unknown. Stand- 

 ing with label in Coquillett's handwriting as Phora cornuta Bigot, 

 an unrecognizable species. 



Type.— Cat. No. 14896, U.S.N.M. 



Genus SYNEURA Brues. 



The only American species so far described of this genus is cocd- 

 phila Coquillett. It was reared from larvae infesting dead adults of 

 Icerya purchasi, collected by C. H. T. Townsend in Mexico. There is 

 quite a large series of this species in the collection. As it is the only 

 American representative of the genus there should be no difficulty in 

 recognizing it. 



Genus METOPINA Macquart. 



TABLE OP SPECIES. 



Larger species, about 2 mm., wings clear, firat division of costa twice as long as 

 second pachycondylse, p. 503. 



Smaller species, at most 1 mm., wings grayish, first division of costa about three- 

 fourths as long as second fenyesi, p. 503. 



MKTOPINA PACHYCONDYL.S Brues. 



Distinct from the other two species in neuration. The fifth vein 

 is not distinctly curved at its base, as in galeata Halliday Siiid fenyesi. 

 Its larger size and the clear wings and also the absence of the peculiar 

 bend in the sixth vein are good characters for separating it from its 

 congenors. 



METOPINA FENYESI, new species. 

 Plate 39, fig. 13. 



Very similar to galeata Halliday, but the wings are grayish, the 

 fourth vein is nearer to the margin than to the fifth in the wing, the 

 fifth vein leaves the third at nearer its apex and with a more rectangu- 

 lar bend than in galeata, and the hind metatarsus is not so much 

 thickened. In color this species agrees closely with the European 

 species. The head is black-brown, thorax brown, abdomen dark 

 brown, yellowish at base, pleurae, coxas, and legs yellow, antennae 

 brown, palpi yellow, arista strongly pubescent, the proclinate bristles 

 are large, being rather stronger than those in vertical row, and there 

 are two scutellar bristles.
