"Wings hyaline, ciliate, the veins brown, the marginal cell closed, 

 the second abscissa of radius very slightly longer than the first, 

 the areolet indicated by a rounded stigma. Abdomen a little 

 longer than the thorax, with a narrow girdle of sparse pubescence 

 at base. 



<S . Length 1 mm. Differs from female only in the antennae ; 

 these are 15-jointed, filiform, about 1| times as long as the body,

 as long as the whole insect ; the first joint of the flagellum being 

 long, nearly twice as long as the second, the third and following 

 joints being slightly longer than the second, three times, or a little 

 more than three times, as long as thick ; the second abscissa of 

 radius is 1| times as long as the first ; while the scutellar channels 

 on each side of the cup are striated. 



Mount Gay Estate (leeward side). Described from one male

 the others, only slightly longer than thick. Scutellum closely 

 reticulately punctate ; the cup small, narrowed, with a minute 

 fovea posteriorly. Wings hyaline, ciliate, the veins brown, the 

 marginal cell closed, the second abscissa of radius about one-third 

 longer than the first. Metapleura bounded by a distinct sharp 

 carina behind. Abdomen piceous at base, the pubescent girdle 

 at base nearly obliterated, only slightly indicated at sides or 

 broadly interrupted at middle above. 



J. Length 1 mm. Antennae 15-jointed, brown; the first joint 

 of the flagellum one-half longer than the second, the third and
