266 ENTOMOLOGICAL SOCIETY 



Phoneutisca bimaculata Loew is evidently a synonym of 

 Tachvdromia maculipennis Walker ; both were founded on speci 

 mens from the far North, and no other known species in this 

 group has the wings marked " with a large brown spot on the 

 fore border at two-thirds of the length from the base," as described 

 by Walker. 



DESCRIPTIONS OF NEW SPECIES. 



Tachydrorriia varipennis, n. sp. 



Near sch-warzi, but the two brown cross-bands on each wing broadly 

 united along the costa. Head black front polished, only slightly nar 

 rowed anteriorly, antennas yellowish brown, about one-third as long as 

 the arista, the third joint short-oval, eyes contiguous below the antennae, 

 palpi whitish, a black bristle at apex of each, proboscis black ; body black, 

 polished, the front edge of pleura whitish pruinose, scutellutn bearing two 

 bristles ; legs yellowish, the tibiae, hind femora, and apices of tarsi brown 

 ish, legs without bristles, no spurs at apices of middle tibiae; halteres 

 whitish; wings smoky brown, the ba>se as far as base of second vein, the 

 apex nearly as far as apex of this vein, and a half-band extending from 

 apex of fifth vein to the third vein, whitish hyaline; marginal cell at apex 

 of first vein scarcely half as wide as the submarginal at the same point, 

 apex of third vein nearly three times as far from apex of the second as 

 from that of the fourth, small crossvein nearly three-fourths of the length 

 of the second basal cell. Length, 2 mm. 



A specimen of each sex, collected at Franconia, N. H., by 

 Mrs. Annie T. Slosson. 



Type. No. 6774, U. S. National Museum. 



Tachydromia lata, n. sp. 



A very broad, robust form, the mesonotum broader than long. Head 

 black, front subopaque, strongly narrowed anteriorly, antennae brown, 

 one-third as long as the arista, the third joint short-oval, eyes contiguous 

 for a short distance on the face, palpi yellow, a black bristle at apex of

 dle tibia and three short bristles at apex of front side of each hind tibia; 

 halteres yellow; wings hyaline, marginal cell at apex of first vein as wide 

 as the submarginal at the same point, apex of third vein nearly twice as 

 far from apex of the second as from that of the fourth, small crossvein 

 near middle of second basal cell. Length, 2 mm. 



Two specimens, apparently males, collected at Lake Worth 

 and Biscayne Bay, Florida, by Mrs. Annie T. Slosson.
