Diptera of 8t. Vincent {West Indies). 375 



A single specimen which agrees with the description 

 in everything save some of the wing-markings. The 

 brown bands of the wings have blackish clouds continu- 

 ing them to the hind margin, and there is a distinct 

 hyaline interval in front of the second vein between the 

 third and fourth bands. 



3. Eiixesta, n. sp. 



A single specimen of a small species differs from all 

 known to me of those having four bands, in the 

 possession of a rounded hyaline spot in front of the 

 second vein and beyond the third band. The purely 

 hyaline interval is situated beyond this spot, and is 

 narrow ; the apical band is narrow, and the brown of 

 the broad second band scarcely exceeds the third vein, 

 but is filled out to the hind margin by a strong blackish 

 cloud. The species is small, the front is brownish-red, 

 the antennae, front cox^e and metatarsi are yellowish. It 

 is labelled " Southern end of the island. Open ground 

 near sea, on herbage. May.^' 



4. Euxesta apicalis, n. sp. (PI. XII., fig. 128, wing.) 



^ , $ . Allied to E. notata, but the costal cell wholly brown. 

 Steel-blue or greeu-blue, but little shining, the abdomen with 

 blackish reflections. Front dark-red or reddish-brown, the orbits 

 narrowly whitish ; the vertex and the upper part of the orbits, 

 blue ; hair black. Antennae brownish-yellow, the third joint oval. 

 Face considerably excavated, and, together with the clypeus, steel- 

 blue, shining, the upper part poUinose ; cheeks reddish. An arcu- 

 ate band extending across the middle of the mesonotum has a 

 more blackish reflection. Coxae and femora light yellow ; front 

 tibiae and tarsi black ; the four posterior tibiae and the distal 

 joints of their tarsi brown, their basal joints yellow or yellowish. 

 Wings hyaline ; the costal and subcostal cells throughout, a small 

 spot in the extreme proximal end of the submarginal cell, and a 

 small spot beginning at the extreme tip of the marginal and ex- 

 tending across the submarginal into the first basal cell, uniformly 

 dark brown ; fourth vein distinctly curved forward, narrowing the 

 first posterior cell ; the fifth vein reaches the margin of the wing ; 

 first section of the ovipositor a little longer than wide, distinctly 

 longer than the last abdominal segment, yellowish at the base ; 

 abdomen for the most part black. Length i-i^ mm 



Six specimens. St. Vincent.
