DELOPSIS. 119 



Legs robust, coxae broad ; femora short, broadly flattened, especially 

 the hind pair ; tibiae spurred, the fore pair without lateral setae, 

 intermediate pair with three ranges of strong spines on the outer 

 and one on the inner side ; hind pair with three ranges of stronger 

 spines on the outer side ; intermediate and hind tarsi spinulose. 

 Wings about the length of the entire body, elongate, rounded 

 off at the base, microscopically pubescent, the hairs not arranged 

 in longitudinal rows. The costal vein ending at the tip of the 

 3rd vein ; the auxiliary short, complete, turned forwards to the 

 costa ; the 5th vein forking much earlier than in Myceto-phila, 

 some distance before the anterior cross-vein ; the 6th vein 

 distinctly short ; the 7th long, reaching the wing-border. 

 Range. Australia^ind Southern India.

 bare of bristles, but a few in front of the wings, two strong ones 

 on the posterior corners and four on the yellow scutellum. Abdo- 

 men brownish yellow ; dorsum of first two segments black ; 3rd, 

 4th and 5th black on dorsum except at base, the colour extending

Subfamily SCIARIN.E. 



The SciABiNjE differ from the rest of the MYCETOPHILID.E taken 

 en masse, in two principal features : (1) the coxae, though some- 

 what lengthened, are normally formed instead of being greatly 

 enlarged, and (2) the anterior cross-vein is very oblique, being 

 always in a direct line with the main length of the 3rd longitudinal 

 vein, that is to say, its length after its short erect basal portion. 

 In their general appearance, their metamorphoses, habitats, and 

 modes of life there is no difference. 



The vast majority of the species fall into the gigantic genus 

 Sciara, and are black or blackish in colour, varied occasionally by 

 a little brown or brownish yellow about the legs or underside of 

 the body ; whilst a few species have reddish abdomens. Very 

 few species are conspicuously marked ; amongst Oriental species, 

 such are, rufithorax, Wulp, indica, Walk., and three new ones 

 herein described, distinguenda, rvfoabdominalis, and luteiventris.
