368 EMPID.E. 



antennae, with facets of uniform size ; proboscis short, thick, 

 vertical ; palpi one-jointed. Antennae inserted a little below the 

 middle, 3-jointed ; basal joints short; 3rd elongate, pointed, with 

 long terminal arista, attached by means of a minute joint. Thorax 

 rectangular, moderately arched ; prothorax forming a short neck. 

 A few uniserial dorso-central bristles ; a notopleural and supra- 

 alar bristle present ; scutellum with two bristles ; metapleura 

 with a few bristles. Abdomen with last two segments in male 

 reduced, hidden by the genitalia, which latter are rather large ; 

 abdomen in female more pointed, genitalia normal. Legs as in 

 Clielipoda fore coxae nearly as long as fore femora. Wings in 

 venation and shape as in Chelipoda; discal cell present; anal 

 angle nob developed. 



Range. Europe, India, N. America, Argentina. 



Life-history unknown. The images frequent grass and damp 

 meadows. 



Phyllodromia, Zstt., differs from Chelipoda, Macq., practically 

 only in the presence of the discal cell, and is ranked as a sub- 

 genus of the latter in the Kertes/ Catalogue ; but if the character 

 is constant one way or the other in all tlie species, there seems no 

 reason why both should not be admitted to generic rank. My 

 flavida was placed in Chelipoda on the broader view of the genus, 

 but must now be transferred to Phyllodromia, with my indica, 

 the latter having been described under Litanomyia, which is now 

 considered synonymous with Zetterstedt's genus. 



P. flavida differs from indica by the thorax being mainly 

 brownish yellow as opposed to blackish grey.

d 1 $ . Head yellowish ; three ocelli on the black vertical triangle, 

 which also carries two divaricate long bristles : frons moderately 

 broad; occiput with four long curved bristles placed equidis- 

 tantly ; seen from behind, the occiput has a greyish tinge, as has 

 sometimes the frons also; eyes black, rounded, almost contiguous 

 immediately below the antennae for a short space, the face 

 broadening below ; the latter, seen from above, appears silvery 

 white ; proboscis very short, half the height of the head, conical, 

 sharply pointed, yellowish, the upper part (hypopharyux) narrow, 

 hard, shining. .First two antennal joints yellowish, with some 

 short bristles at the tips of each ; 3rd joint dark br.mvn, elongate 

 onion-shaped, with long brown microscopically pubescent arista. 

 Thorax very variable, generally brownish yellow, with more or less 

 blackish colour, either in the form of a dorsal stripe, a lateral ir- 

 regular and somewhat indistinct border, or the posterior part of the 

 dorsum more or less blackish; sides generally lighter, in some speci- 

 mens attaining a pinkish-fawn colour. Abdomen variable, brownish 

 yellow, more or less blackish in part or wholly ; venter brownish
