margin rounded; four bristles present, the basal two much shorter 

 than the widely placed apical pair, disk with short hairs. Legs with 

 pale, short, surface hairs; apical spur on hind tibia strong, bent, 

 situated a little before apex of tibia and about one-half longer than 

 tibial diameter. Wings with veins 2 and 3 bent up a little at their 

 apices; third division of costa a little over two-thirds as long as 

 second; veins 3 and 4 divergent, the latter straight, finishing just below 

 apex of wing; outer cross vein oblique.

21. HIPPELATES SUB/EQUALIS, new species. 

 Fig. 29, 37. 



Female. — Shining reddish yellow; triangle entirely yellow, or with 

 the ocellar spot darkened; the thorax has a black spot low down in 

 front where it is connected with the head, and the abdomen is brownish 

 apically. Wings browned slightly ; veins brownish yellow. Halteres 

 yellow. Hairs yellow, bristles brownish yellow. 



Frons occupying about one-half the width of head; triangle nearly 

 as wide as vertex, and extending to anterior margin of frons; antennas 

 rather above average size, third joint rounded; arista distinctly 

 pubescent, brown, and longer than width of frons; cheeks linear; 

 eyes higher than long; proboscis short. Mesonotum narrowed 

 anteriorly, impunctate, hairs irregularly arranged, scutellum sub- 

 quadrate, the posterior margin sometimes concave in outline; apical 

 bristles situated on posterior angles, cruciate, diskal hairs and other 

 marginal bristles weak. Legs slender; hind tibial spur long, reaching 

 to beyond middle of metatarsus, curved, its base at apex of tibia. 

 Wings with third costal division equal in length to second; third and 

 fourth veins slightly divergent. 



Length, 1.25-1.75 mm. 



Type.— Cat. No. 15967, U.S.N.M. 



Type-locality. — Montserrat, Trinidad, West Indies, June 29, 1905 

 ^A. Busck). 



Paratypes. — Six specimens same data. 



There is a single specimen from Tabernilla, Canal Zone, Panama, 

 taken by the same collector, which agrees in most respects with the 

 type, but has a black central streak on the triangle. 



This species is very close to equalis Williston, but I believe it is 

 distinct, though Williston's description is not very comprehensive.
