UOAVLETTIA. 361 



of three disHuct joints; first two short, subequal ; 3rd shortly 

 conical, with a long terminal arista. Proboscis about equal to 

 height of head, perpendicular ; palpi half as long as proboscis or 

 rather longer, quite broad. Tliorax normally arched. Abdomen 

 rather longer than thorax, somew^hat compressed. Legs i-ather 

 long and slender ; fore coxae slightly longer than posterior pairs ; 

 middle femora somewhat incrassated ; all tarsi longer than tibia?. 

 Wiwjs with auxiliary vein faint and incomplete; 1st longitudinal 

 vein rather further from costa than usual, ending beyond middle 

 of wing ; 2nd vein beginning at one-fourth of wing, ending 

 towards tip of coota ; 3rd vein beginning at middle of wing ; 

 anterior cross-vein just beyond origin of 3rd vein, which latter 

 ends at about wing-tip ; itli vein nearly straight, ending just 

 below wing-tip; oth nearly straight; 6th (anal) very long, com- 

 plete to wing- border. Posterior CTOss-vein meeting 4th vein at 

 spot where anterior cross-vein meets it, but not in the same 

 straight line ; anal cross-vein nearly perpendicular to anal vein ; 

 2nd basal cell slightly longer than 1st, apex pointed ; anal cell 

 barely half as long as 2nd basal ; discal cell absent, 

 c? unknown. 



Range. Only the type-species known. 



The genus is named after Mr. F. M. Ilowlett, of the Agricul- 

 tural Research Institute at Pusa.

o . Head blackish ; proboscis dark brown ; palpi brownisli 

 yellow; ocellar triangle rather prominent. Ihora.v shining 

 black, with very short whitish pubescence towards margins of 

 dorsum ; sides of thorax and dorsum of scutellum slightly grey- 

 dusted ; a few weak prealar bristly hairs. Abdomen black, a little 

 shining; venter brownish yellow, with a little very short whitish 

 j)abescence. Legs brownish yellow, minutely pubescent, middle 

 femora a little incrassated, with a row of very short bristles on 

 underside; tarsi blackish. Wings clear, iridescent ; venation in 

 accordance with generic description ; halteres dull brownish 

 yellow. 



Length, 2| mm. 



Described from a single $ in the Pusa collection, now sent to 

 the British Museum, from Mussoorie, ix. 190G (IJawlett). 



This genus is left in the subfamily Empin.e for the present, but 

 it is distinctly anomalous, and does nor, exactly fit into any sub- 

 family. The distinctly though only moderately incrassated middle 

 femora suggest the TACiiYDKOMiiN.i:, from wiiicli the very distinct 

 anal cell and complete anal vein combined separate it. The 

 absence of the discal cell makes it abnormal in Empix.i:. It has 

 alHnities with the OcYDROMiiy.E in tiie less distinct anal angle of 

 the wing, though it is by no means cuneiform, also in the anal 

 cross-vein being perpendicular to the nnal vein.
