Elaphropeza upsilon, sp. nov. 

 cf . Length 1.5 mm. Largely yellow with yellow legs and antennae, 

 the posterior part of the mesonotum marked with a broad U-shaped 

 mark, hind tibiae with a single extensor bristle located just before its 

 middle, middle tibice microscopically denticulate along the flexor side. 

 Head black, occiput pollinose up to the eyes, face linear, white-pollinose ; 

 mouthparts yellow; third antennal joint short -ovate, the arista less 

 than three times as long as the antennse and microscopically pubescent; 

 vertical and ocellar bristles yellow. Hairs of the mesonotum rather 

 sparse and long, bristles yellow; the black mark fills the posterior half 

 of the mesonotum except in the middle and except the postalar callus; 

 scutelltim, metanotimi and middle segment of the abdomen black, the 

 middle segment of the abdomen with scale-like setulse along the sides; 

 pygidium brown, glabrous except the marginal fringe. Hind tibiae 

 with a moderate, acute, yellow, velvety, terminal lappet. Veins brown, 

 second and third sections of the costa nearly equal, third and fourth 

 veins nearlv parallel, sections of the fourth vein proportioned 1:1: 2.2, 

 of the fifth vein, 1 : 0.4.

Elaphropeza vittata, sp. nov. 

 9 . Length 1.8 mm. Robust, yellow marked with black. Occiput 

 black, lightly pollinose, its bristles and the ocellars pronounced; front 

 linear, its sides parallel, eyes separated below the antennae by a dense 

 row of microscopic white hairs; palpi white and with white hairs, 

 proboscis yellow; antenuEe destroyed. Thorax polished reddish yellow, 

 marked with a black vitta which is broadest behind and there includes 

 the scutellum and metanotum and meets a black pleural vitta. The 

 median vitta is not sharply bounded, the pleural vittae fill the meso- and 

 meta-pleurae. The thoracic hairs are rather long and isolated, two rows 

 of six acrostichal hairs, a pair each of prescutellar and scutellar bristles. 

 Abdomen pale yellow, only the middle segment fully chitinized, the 

 basal segments with only small lateral sclerites, the sides of the middle 

 segment with many glistening scale-like setulae. Legs yellow, the ante- 

 rior tibiae and all of the tarsi a little brownish, anterior femora with a 

 moderate preapical bristle, hind tibiae with two strong extensor bristles 

 trisecting their length, their terminal spur long and sharpened, pale 

 brown. Halteres white; calypteres ciliate with five brown hairs. 

 Wings clear hyaline, veins yellow, third section of the costa nearly 

 twice as long as the second or fourth, third and fourth veins parallel at 

 the end, anterior cross- vein before the middle of the second basal cell, 

 outer sections of the fourth vein proportioned 1 : 2.5, of the fifth vein, 

 3:1, hind margin with short cilia. 



Type specimen from the U. S. National Museum, labeled 

 "on pineapple," Lemon City, Florida, April 12, 1899. A 

 defective specimen from Havana, Cuba, (Dr. A. H. Sturtevant), 

 is apparently the same, differing in that the pleural blackening 

 is less pronounced.
