fully hall as long as tibia, but uot so long as the four following joints; 
the whole tarsus a little longer than the tibia; hind tibiæ quite simple. 
Length. The species may vary somewhat in size, from 3,5 
to nearly 5 mm., the female is smallest. 
Not quite mature specimens may have the legs, especially the 
front legs, somewhat brownish, and the base of abdomen more trans- 
lucently brown. 
This species seems to be somewhat nearly related to H. di - 
midiata Strobl (according to the description), but it is distinguished 
by se veral characters, among others a different coloration of 
thoiax and distinet marginal bristles on abdomen; also the front 
legs are differently constructed; the female is at once distinguished 
by the quite simple hind tibiæ. It may also remind one of H. 
lurida Fali., but the male has thicker front metatarsi and both 
sexes are distinguished by the quite regular quadriserial acrostichal 
bristles. Among the Danish species it will be known without 
difficulty, and it will be easily placed in the table I have given in 
Dipt. Dan. III; it may here I think only be sought under division 
8 , and here are only two species, H. nigrina , which is very diffe¬ 
rent by the dark wings and duli black abdomen, and quadrifaria, 
which has a blackish brown thorax; both species have in the female 
thickened hind tibiæ. 
H. anglodanica was first found in 1911 when I took five 
specimens on Bornholm in the wood Almindingen; in 1912 it was 
not uncommon in Dyrehaven at Copenhagen, flying ower ditches; 
this is somewhat curious, for in the preceding years, when I eagerly 
collected species of Hilara on several localities, I did not at all 
observe the species. My dates of capture are 29 /e — 10 /s. 
When I corresponded with Mr. C o 11 i n about the species, he 
kindly informed me, after having examined it, that it is not un¬ 
common in England, its geographical distribution thus at present 
being Denmark and England.
