JSmpidideicus, Becker, Zeits. f. Hymen, u. Dipt, vii, p. 97, fig. 

 (1907). 



Genotype, Empidideicus carthac/iniensis, Beck. ; by original 

 designation. 



Very small bare species. Head placed low on the thorax ; 

 antennae with 1st joint microscopic, 2nd extremely short, 3rd 

 comparatively large, elliptical, with small apical thickly pubescent 

 style ; occiput more or less puffed out. Thorax considerably 

 arched. Abdomen of six distinct segments. Legs simple, 

 moderately long, bare. Wings with distinctive venation : aux- 

 iliary vein short, ending free; 1st vein ending at about middle of 

 costa ; 2nd vein absent (genotype) or present (indicus) • when 

 present, very' short, turning sharply upwards and ending in 1st 

 vein near its tip ; 3rd vein simple, ending at some little distance- 

 before wing-tip ; 4th vein forked, sometimes indistinct on the 

 portion dividing the basal cells ; 5th vein forked, base of upper 

 branch forming lower side of 2ud basal cell ; 6th vein attaining 

 wing-border ; anterior cross-vein present ; discal cell absent ; 

 one submarginal, three posterior cells ; anal cell open ; squamae 

 absent. 



Allied to Glabellula, Cyrtosia, and Apolysis, only one other

2 . Bead : frons apparently about one-fourth width of head,

 Abdomen black, hind margins of segments pale yellow, and a

 Legs black, knees and tips of tibiae yellowish. Wings pale grey ; 

 auxiliary vein short, ending free ; 1st vein ending at middle of 

 costa ; prasfurca beginning at middle of 1st vein ; 2nd vein very 

 short, directed abruptly upwards, ending in 1st vein near tip ; 

 3rd vein in line with praefurca, simple, ending a little before 

 wing-tip ; 4th vein forked at half its length after quitting basal 

 cells, the section dividing those cells hardly less distinct ; 5th 

 vein forked, base of upper branch forming lower side of 2nd basal
