Diptera of St. Vincent (West Indies). 433 



Wings lightly tinged with brownish j first section of the costa with 

 bristles ; second section a fourth or a third longer than the third 

 section ; the third vein is conspicuously curved forward and 

 terminates distinctly before the tip of the wing ; fourth vein 

 beyond the discal cell feebly represented, gently curved. Length 

 2|-3 mm. 



Numerous specimens. St. Vincent. 



4. Limosina joerparva, n. sp. (PI. XIY._, figs. 161, 

 wing; 161a, antenna.) 



(^. Front and face opaque-black. Antennae obscurely yellow, 

 the third joint whitish pubescent, heart-shaped, with a terminal 

 arista ; arista black, pubescent. Thorax and scutellum deeply 

 black, the former shining, the latter opaque. Abdomen black. 

 Legs black ; the tip of the tibiae and the tarsi yellowish ; hind 

 metatarsi nearly as long as the second joint. "Wings nearly'- 

 hyaline ; the second vein joins the costa in a very acute angle, and 

 is concave on the posterior side throughout ; costa with longer 

 bristles on its first section. Length 0'9 mm. 



One specimen. 



b. Limosina lugiibris, n. sp. (PI. XIY., fig. 162, wing.) 



^ , $ . Face and cheeks yellow or brownish-yellow. Antennae 

 yellow, the third joint brownish at the tip, w^hitish pubescent, 

 heart-shaped, the finely-pubescent arista terminal ; second joint 

 with a coronet of strong bristles. Front opaque-reddish or 

 brownish-yellow. Thorax, scutellum, and abdomen black shining ; 

 scutellum flattened. Legs yellow, middle tibiae with bristles on 

 the under side. Wings tinged with brownish, with a narrow 

 cross-band and the tip more nearly hyaline ; the third vein takes 

 its origin beyond the insertion of the first ; the first section of the 

 third vein is a little shorter than the terminal section of the 

 second vein, and the third section of the costa is nearly three 

 times the length of the second section ; posterior cross-vein but 

 little longer than the anterior cross-vein. Length l|-mm. 



One specimen. With this specimen there is another, 

 which has the front brown above, the pleurae brownish- 

 yellow, the wings rather narrower, not clouded, 

 and with the distal section of the third vein more 

 nearly straight, and terminating exactly at the tip of 

 the wing. It undoubtedly belongs to a diflferent 

 species.
