ASILINiE. 



Marginal cell closed (fig. 345). Third antennal joint with a terminal 

 style or arista. 



Fia.34o.—FliilonimsalUce2)s jj. x 4. 



Head wide and sliort. Face almost equally broad or gradually widening from 

 the antenns! to the mouth, usually bare on the upper part and against the eyes but 

 with a conspicuous face-beard which practically covers the facial knob (when that is 

 present), or the whole face may bear pubescence quite up to the antennae and out to 

 the eyes ; face-beard composed of long bristles or bristly hairs or even soft hairs 

 which droop downwards on the lower part over the front of the mouth-opening. 



Frons almost equally ^vide in both sexes and the eyes scarcely ever in any way 

 approximated in either sex, deeply sunk at the upper part so that there is a deep 

 depression at the vertex between the top inner eye-angles, and the middle channel 

 of this depression nearly always bare and divided out forwards down each side of 

 the rather elevated ocellar space ; several small bristles or bristly hairs occur about 

 the ocelli, and below this part the orbits bear small bristles almost down to the 

 antenna?, but the middle of this part of the frons is always bare. Chm and jowls 

 with long fine-haired dense pubescence. Back of the head bearing pubescence and 

 (with rare exceptions) on the upper half (or thereabouts) a postocular "festoon' of 

 stout usually black bristles near (but not quite close to) the eyes ; this " festoon 

 may be composed of only a few stout straight blunt bristles, or more commonly oi a 

 rather conspicuous row of bristles which towards the upper part have their tips bent 

 over forwards and sometimes even bent over rectangularly (Xeoitamus). Proboscis 

 strong, sloping or almost horizontal ; palpi one-jointed distinct though not con- 

 spicuous, sometimes with bristly hairs (Craspedia). Antennas porrect ; two basal 

 joints comparatively short and bearing short bristles ; third joint almost bare, more 

 elongate, and bearing at its end a style or arista which is bare in all European 

 species, but which bears a thin comb-like ciliation in the extensive exotic (or
