NO. 2024. FLIES IN SUBFAMILY BOTANOBIIN^—MALLOCH. 247 



Pleurse reddish yellow. Abdomen elongate; shining black, at its base obscurely 

 reddish. Legs yellow, the hind tibiae somewhat and the last two joints of the tarsi 

 brown. Wings nearly hyaline; third section of the costa as long as the second 

 section. 



Length, 2f mm. 



One specimen. St. Vincent. 



I have not seen this species, which, if it is a Hippelates, must be a 

 very distinct one. Becker says "Aus Knba, St. Vincent" (coll. 

 Williston), but as he does not indicate in his paper that he has seen 

 specimens I infer that he has made a geographical error. The 

 description reads very like that of a Siijhonella or Botanobia species. 



7. HIPPELATES TRUNCATA, new species. 

 Figs. 7, 9, 10. 

 FemaZe.— Glossy black; frons opaque, except triangle, sometimes 

 brownish anteriorly, proboscis and palpi black or brown, antemise 

 yellow; arista brown; base of abdomen generally yellowish, and apex 

 sometimes pale yellowish brown. Legs yellow; femora except bases 

 and apices black, glossy; tips of tarsi brown. Wings generally 

 slightly browned; veins brown. Halteres clear yellow. Hahs and 

 bristles black or brown. 



Frons about one-third wider than either eye, slightly longer than 

 broad, triangle glossy, elongate, at its upper margin occupying 

 nearly the entire vertex, extendmg to anterior margin of frons, sides 

 straight, margui with a row of hahs situated in slight punctures; 

 frontal stripe opaque, very indistinctly haired ; antenna of moderate 

 size, third joint rounded, and covered with short pubescence; arista 

 distinctly longer than breadth of frons, and with sparse, but distinct, 

 pubescence; cheeks very narrow, almost linear; a short bristle at 

 anterior angle, the marginal bristles short, but distinct; eyes about 

 1| times higher than greatest length, bare; proboscis short; palpi 

 of normal size. Mesonotum wdth the disk covered with irregularly 

 arranged hairs, each of which is situated in a shallow puncture, the 

 lateral rows almost indistinguishable; scutellum flat, distinctly 

 broader at base than long, sides converging posteriorly, posterior 

 margui truncate, at each angle posteriorly there is a small, but dis- 

 tinct, tubercle, on each of which is situated a long bristle, the other 

 margmal hairs short. Legs with hind femora slightly incrassated 

 and a little bent, hind tibige with the apical spur twice as long as 

 tibial diameter, strongly curved, and situated at apex. Wings with 

 second and third costal divisions subequal; veins 2-3 curved up at 

 extreme apices; veins 3-4 divergent, the latter almost straight and 

 ending in wing tip; last section of fifth vem slightly longer than 

 penultimate section of fourth; surface of wing with the microscopic 

 hairs unusually distinct. 

 Length, 1.5-2 mm.
