SCOTTISH PHORIDJE 91 



to middle of wing, second vein present ; first thin vein bent at base 

 and reaching the margins considerably in front of the wing tip ; 

 hind tibiae bare. 



The only species is umbrimargo, Beck. It cannot be placed in 

 either Phora as defined by Brues, or in his Aphiochata because of 

 the peculiar direction of the post-antennal bristles. Thus although 

 it is unfortunate that a single species should have a genus allotted 

 to it, it is, I believe, necessary in this case. I have taken the 

 species here not uncommonly, and expect that it may occur almost 

 all over the country. The other localities I know of it having been 

 recorded for are Durham and Hereford. 



APHIOCH^ETA, Brues. 



I hope shortly to be able to deal with this group, but meantime 

 must restrict myself to giving a list of those species that I know as 

 occurring in Scotland.
