AMERICAN DIPTERA. 59 



lowish. Legs yellowish, the terminal half of tarsi, and front and middle tro- 

 chanters blackish, the middle and hind femora tinged with brownish. Wings 

 dear, costal cells very dilute yellowish. 



Dixie Landing, Va., June 22. One female. 



12. TabanuKi alene n. sp. 



Length 10 mm. — Rather nearly allied to T. parvuJus Willist. from Santo Do- 

 mingo. Front of moderate width, quite parallel. Antennse reddish yellow, the 

 annulate portion and angle of third joint black, with a slight tinge of black 

 on other joints distally; frontal callosity nearly square, pointed above, co7ivex 

 ibelow. Eest of front yellowish gray poUinose, with a brownish shade on vertex, 

 and another between latter and callosity; subcallus not denuded, yellowish gray 

 poUinose ; third antennal joint not wide at base, very narrow, but with a distinct 

 angle. Face with a white bloom and white pile; palpi pale yellowish tawny; 

 pleurae and sternum with whitish pile. Doi'sum of thorax light brown, with five 

 yellowish gray vittse, the sides and posterior border lighter. Scutellum of same 

 brown, with a lighter border. Abdomen pale yellowish brown, the last three seg- 

 ments darker ; all the segments with a narrow grayish hind margin, which is 

 dilated into a small median triangle on second to fourth. All the segments with 

 a vestige of a whitish poUinose spot on each side, each separate and not touching 

 borders of segment. Legs pale brownish yellowish, tarsi darker. Wings hyaline ; 

 the stigma, furcation of third vein, small cross-vein and origin of third, and cross- 

 veins at distal end of second basal and discal cells, narrowly clouded ; costal cells 

 quite clear, except at stigma. 



Bath, Jamaica (Mrs. E. M. Swainson) ; one female. Type in coll. 



Townsend. 



13. Tabauus augn!«tifroiis n. sp. 



Length 9-11 mm. — Pale yellowish brown ; no limpid spots on wings, wliich 

 show no mai'ked cloudiness, but are only yellowish on costal portion ; first two 

 antennal joints reddish yellow, the third wholly black. Abdomen yellowish 

 brown, with hind margins of segments pale yellowish gi'ay, enlarging into a 

 triangle in the middle and forming an approach to a median line ; front is very 

 narrow and parallel, eyes bare. Basal enlarged section of third antennal joint 

 distinctly angular above ; palpi tawny grayish. Legs brownish, bases of tiliiae 

 and tarsi lighter. 



Jamaica. Two female specimens. One from Cinchona (5000 feet), 

 Jamaica, August, 1893, W. Fawcett. A small species. 



This is not T. lucidalus Wlk., as it has no limpid spots on wings. 

 I doubt that it is T. rajiventris Mcq., as identified by Walker, which 

 was from Cuba. At any rate Macquart's description is too meagre 

 to be certain. It is none of the Santo Domingo or other new species 

 described by Williston i^in " Trans. Kans. Acad. Sci." x). Macquart 

 described rufive)itri>< from a male specimen, which makes the detei-- 

 mination of that species at the best very uncertain, and doubtless 

 Walker's determination of it from Jamaica is wide of the mark. 

 T. rufiventris should, therefore, be dropped from the Jamaican list 

 of Diptera until competently identified.
