The female of this species differs from the male in nothing 

 tut its sexual characters and in having the antennae stout 

 with the six basal flagellar joints subserrate, and in its greater 

 length of 4| mm. The typical male form is from Austria and 

 not yet recorded from Britain ; the female is here described for 

 the first time. 



The British varietal male was taken in England with the 

 ant, Myrmica scabrlnodis, by Donisthorpe, and subsequently in 

 France by Andre. But the typical form also occurs here, since 

 Tuck sent me one from Tostock in Suffolk during September, 

 1900 ; and both sexes have occurred to me in the same county 

 at Eriswell, where I swept the new female from dry grasses, 

 and at Tuddenham Fen, as well as at Edwinstow in Sherwood 

 Forest, all during August.

Var. pallidistigma, var. nov. — Under this name Chitty had 

 ranged as a distinct species a number of specimens differing 

 slightly from the typical form in having the stigma testaceous 

 and quite remote from the apical abscissa of the radial nervure, 

 leaving the radial cell comparatively broad. It is a good deal 

 rarer than the ordinary form ; Piffard has found it at Felden, 

 Saunders at Keigate, Morey at Bookley in the Isle of Wight ; 

 I have taken it on the Felixstowe cliffs in Suffolk and swept 

 it at Wicken Fen in Cambs. 



Italy, Hungary, Switzerland, Germany, France, Sweden, etc. 

 Not infrequent in woods during autumn ; found by Walker 

 and Haliday, presumably in both England and Ireland. 

 Vollenhoven tells us (Pinac, p. 31) that it has been bred from 

 the fungus-gnat, Brachycampta griseicollis, Staeg., which occurs 

 in England. This is one of our most abundant species of the 

 subfamily, though very rarely seen on the boulder-clay at 

 Monks Soham and never on honey-dew ; it is nearly always
