EMP1DJE. 325 



or at an angle of about 45 to hind 

 margin of wing ; anal cell with either 

 anterior or pgsterior margin the 

 longer, its apical end truncate or 

 pointed ; proboscis generally shorter 

 than or as long as height of head, 

 sometimes longer ; 3rd veiu simple 

 or forked ; thorax humped or not . . 4. 

 4. Proboscis as long as or longer than 

 head,* projecting downwards; lower 

 branch of oth vein parallel to hind 

 margin of wing, so that anterior 

 margin of anal cell is always the 

 longer ; antennae comparatively elon- 



fate, generally with 2-jointed style ; 

 rd vein simple or forked EMPIXJE, p. 344. 



Proboscis generally quite short ; if as 

 long as head or longer, directed 

 straight or obliquely forwards, also 

 5th vein meeting anal vein at an 

 angle of about 45, also antennae and 

 style very short. Antennae vari- 

 able ; lower branch of 5th veiu 

 meeting anal vein parallel with, 

 perpendicular to, or at, an angle of 

 45 to hind margin of wing ; 3rd vein 

 simple OCYDROMIIX^E, p. 362. 



Subfamily HYBOTINyE. 



Eyes contiguous in both sexes ; proboscis varying from shorter 

 than, to a little longer than the head ; palpi of one joint ; an- 

 tennae 3-jointed, with a terminal arista.* Thorax very humped. 

 Wings with axillary lobe well developed ; 3rd longitudinal vein 

 simple, 4rli simple or forked ; three or four posterior cells ; discal 

 cell generally present ; t 2nd basal cell equal to or longer than 1st ; 

 anal cell longer or shorter than 2nd basal ; anal vein reaching 

 margin of wing ; lower branch of oth vein bent down rather 

 suddenly, at an obvious obtuse angle, meeting anal vein approxi- 

 mately perpendicularly to hind margin of wing, making posterior 

 side of anal cell always the longer, and its apical end pointed. 



The characters by Avhich this subfamily may be most easily 

 recognised are the elongated anal cell, pointed at tip, in conjunction 

 with the obtusely bent lower brand) of the 5th vein ; also by the 

 very humped thorax. They are strongly built Euipids and of 

 comparatively large size. 



* Trichopeta is almost an exception, the proboscis being barely as long as 

 the hoad. 



t Microsania, Zett., a European genus, lias a two-jointed ttyle to the 3rd 

 antennal joint and the discal cell absent.
