NO. 2024. FLIES IN SUBFAMILY BOTANOBIIN^—MALLOCH. 245 



The Cuban specimen differs slightly from the one from Porto Rico, 

 but I do not consider it sufficient to warrant me in describing it as 

 distinct.

Male and female. — Colored as last species, but as a rule the anterior 

 margin of frons is only narrowly yellow, and the third antennal joint 

 is distinctly darkened above. 



Frons occupying rather more than one-third the width of head; 

 frontal triangle occupymg almost entire ^vidth of frons at vertex, and 

 reaching to almost the extreme anterior margin of frons, its sides 

 straight, or slightly concave, hairs as in previous species; cheeks very 

 rarely yellow in the type form, distinctly so in hicolor; eyes bare, 

 slightly higher than long; antennae of moderate size; arista slightly 

 pubescent, as long as width of frons; proboscis glossy, black-brown, 

 the apical portion bent back under the subapical almost as far as the 

 length of that section. Mesonotum rather thickly covered with short 

 hau-s, the two lateral rows not easily distinguished except by the 

 more distmct puncturation, the other hairs irregularly arranged, each 

 with a shallow puncture at its base ; the surface hairs and bristles are 

 sometimes almost black, very rarely yellowish; scutellum with the 

 apical pair of bristles cruciate, not closely approximated, the swelling 

 at then- bases very small. Abdomen generally yellow on basal two 

 segments, but sometimes with three longitudmal rows of black spots 

 (var. hicolor). Legs reddish yellow, the hind tibial spur situated 

 well in front of apex of tibia, distinctly bent- and much longer than 

 diameter of tibia. Wings clear, veins yellowish; vems 3-4 sub- 

 parallel; last section of fifth vein subequal with penultimate section 

 of fourth, or slightly longer. 



Length, 1.5-2 mm.
