36 Pjpunculidae. 



large, black, a little brownish grey pruinose, with a narrow oval 

 apical impression with a protruding longitudinal keel-shaped fold. 

 Legs with the femora somewhat robust, though less than in varipes; 

 the legs are black with the knees and the basal part and very apex 

 of tibiæ yellow, tarsi more or less blackish brown and also the troch- 

 anters may be brownish; the femora are all shining below, hind 

 femora also on the posterior side; the legs are short-haired, middle 

 femora with a longish pale ciliation behind, and front and hind 

 femora with a similar but less conspicuous pubescence, hind tibiæ 

 with some longish hairs below the middle on the anterodorsal side; 

 the femora have two rows of small spinules below the apical part, on 

 the middle femora stretching over two thirds. Wings a little brownish 

 tinged, stigma brown or pale brown, distinctly longer than next 

 costal segment, middle cross-vein at the first third of the discai 

 cell, Halteres yellowish. 



Female. Frons quite grey with a very slight, almost impercept- 

 ible median keel and a very small elevation above the antennæ; 

 antennæ with the third joint brown or yellowish, more pointed than 

 in the male or slightly rostrate. Thorax with the front part more 

 dusted than in the male and more greyish, sometimes rather dusted 

 all over, it is conspicuously grey round the humeral knob. Abdomen 

 as in the male but without velvet front margins, and second segment 

 grey on its front part or entirely grey. Hypopygium with an oval, 

 black and shining basal part, the reddish ovipositor is longer than the 

 basal part, straight or very slightly recurved. Legs paler than in the 

 male, trochanters and base of femora yellowish, tibiæ nearly all yellow 

 with only a black patch ventrally below the middle, and tarsi yellowish, 

 a little darkened outwards with the last joint black. Wings with the 

 stigma shorter than the next costal segment. 



Length 4 to about 6 mm. 



The species shows resemblance to varipes, but this species is 

 besides by the much more shining thorax distinguished in the male 

 by the velvet bands on abdomen, and in the female by the distinctly 

 recurved ovipositor, and in both sexes it has much paler legs and, 

 especially in the male, all femora more shining behind.
