10. LAPHRIA 695 



Proboscis remarkably long, bristly dorsally ; palpi long, densely 

 bristly. Thorax with only sparse short bristles in place of pubescence 

 on the disc, but with numerous lateral bristles. Hind femora more 

 or less club-shaped and not sinnose beneath, but the legs with scattered 

 strong bristles and very little pubescence. First posterior and discal 

 cells long and narrow. Large Dasy2}ogon-V\kG. flies. 



* Lamyra. 



8 (7) Veinlct closing the fourth posterior cell by no means parallel 



with the wingmargin. 



9 (12) Antennce rather short, the third joint club-shaped. 



First posterior cell usually closed. 



10 (11) Pubescence rather slight and suberect. 



Face produced on the lower part ; bristles on the back of the head 

 all weak and not forming a festoon. Scutellum densely bristly haired 

 about the margin. Femora and tibiae almost without bristles. 



Andrenosoma. 



11 (10) Pubescence conspicuously coarse and adpressed on the thorax, 



abdomen, and legs. 



Face without any prominence or bristles though with dense 

 pubescence. Thorax with supra-alar and postalar bristles ; scutellum 

 with dense marginal bristles. 



Ctenota. 



12 (9) Antennas rather long, the third joint not club-shaped. 



First posterior cell usually open. 



10. Laphria. 



There is an inclination at the present time to divide 

 Lci'pliria as follows. 



1 (2) Thorax woolly haired and quite without bristles. 



Proboscis short and thick. Dasyllis. 



2 (1) Thorax with inconspicuous dorsal pubescence and 



with traces of lateral bristles. Proboscis pro- 

 minent and only moderately thick. Laphria. 



This division would place Laphria fiava and its allies in 

 Dasyllis, but L. marginata and its allies in Laphria. Loew 

 however with a full knowledge of the European species, 

 formed the genus Dasyllis for L. ha:morrhca Fabr. and some 

 well-known American species, with which he united some 

 doubtfully congeneric African ones, in which the first posterior 

 cell is closed. 



10. LAPHRIA. 



Laphria Meigen, lUig. Mag., ii., 270 (1803). 



Moderately large to very large robust flies of blackish 

 or reddish colour, often densely clothed with bright and hand- 

 some pubescence. 



Head broad but short ; face on the upper part level with the eyes but produced 

 into a distinct facial knob, and the pubescence on this knob usually of a more 



* Not truly Paleearctic, though included io Kertesz's Katalog.
