SCOTTISH PHORID^E 17 



19. (20.) Sub-apical spine on mid tibise weak and small, situated on 



outer side near the tip, hind tibise with a row of small 

 bristles on the outer hinder side in addition to any 

 stronger bristles that may be present ; anal protuberance 

 long and finger like ; first thin vein almost straight at 

 base. P/iora, Latr. 



20. (19.) Mid tibise with sub-apical spine always well developed, and 



situated on the outer side at about one-third from the 

 apex ; hind marginal small bristles absent ; first thin 

 vein strongly bent at base. Spiniphora, Mall. 



21. (18.) Scutellum with two bristles, one hind tibial bristle, sub- 



apical mid tibial bristle weak or absent ; frontal bristles 

 strong. Stenophora, Mall. 



22. (12.) Mid tibise with one basal bristle ; frontal bristles weak. 



Parastenophora, nov. nom. 



23. (13.) Third thick vein unforked, second vein absent. 



Hypocera, Brues. 



24. (11.) Post-antennal bristles not reclinate. 



25. (26.) Post-antennal bristles erect. Beckerina, nov. gen. 



26. (25.) Post-antennal bristles proclinate. Aphiochata, Brues. 



PLATYPHORA, Verr. 



Lubbocki, Verr. easily distinguished from all other Phoridcz by 

 its PlatyptezaJflzR shape, and the absence of bristles. The only 

 specimens I have seen were from New Forest (King). 



GYMNOPHORA, Mcq. 



amtata, Mg. The only species of the genus is easily recognised 

 by the bare frons and legs. The wings have the thick veins much 

 thickened, and the whole insect including the wings is extremely 

 dark. Very common among ferns and undergrowth. I have seen 

 it from various parts of Scotland, and take it here commonly. 



CONICERA, Mg. 



1. (2.) Third antennal joint in $ about 2-i times as long as its 



basal breadth. atra, Mg. 



2. (i.) Third antennal joint in 6* about i| times as long as its 



basal breadth. simi/is, Hal. 



Both species are about equally common, but owing to their 



somewhat similar appearance, they are not readily distinguished. 



I have taken both species at Bonhill and Cardross, and have seen 



atra from Cambridge, so that this species, at least, has a wide range.
