106 Orthonhapha lnacliyceia. 



H. crnssicoruis is not at all coininon liere; I have seen some 

 specimens presumably taken in the vicinity of Copenhagen, and in 

 Jutland it has been taken in single specimens at Silkeborg (A. Petersen) 

 and Frederikshavn (H. I. Hansen). My records date only from ■' ; lo -^i-. 



Geographical distribution : — The species occurs in northern and 

 middle Europe, including Britain, down to Styria.

This species also nmch resembles pluvialis so that I shall content 

 myself with describing it comparatively. 



Male. The erect hairs on the vertex moderately long, yellowisli. 

 towards the sides tliey may be darker. Antennæ rather long, first 

 joint moderately thickened. long ovate, grey pruinose. Thorax as in 

 pluvialis, the pubescence more or less pale yellow, sonietimes whitish. 

 Abdomen is also quite as in pluvialis, with tlie same reddish mark- 

 ings, stretching over the sides of the three first segnient. Legs often 

 with the femora more or less yellow. 



Female. Antennæ long; tirst joint long, cylindrical, not thickened 

 as long as or longer than the third, indistinctly constricted at the tip, 

 quite grey. The pubescence on thorax and abdomen pale grey or 

 whitish. 



Length 9—12 mm. 



This species may be known in the male by the moderately 

 thickened and somewhat long first joint of the antennæ, which is 

 grey to, or near to, the apex, and by the pale hairs on the vertex; 

 in the female it is easily recognised by the long. cylindrical, grey 

 first joint of the antennæ. 



H. italica is as common as pluvialis or nearly so, and it occurs 

 often together with this species; Copenhagen, Dyrehaven. Ordrup Mose, 

 Ørholm, Hillerød, Donse, Jægerspris; Funen at Hoffmansgave by 

 Odensefjord, and from the little Eiland Endelave north of Funen; 

 from Jutland I have not seen it. My records dates from ^'hi to ''s. 



Geographical distribution : — Europe, towards north to the middle 

 of Sweden. 



The species of Hæmatopota are not at all easy to distinguish, 

 but I think the characters given above will prove to be sufficient. 

 H. variegata Fabr., which was first described from Tangiers, I do 

 not know, and the descriptions of it are not quite plain. On account 

 of the reddish markings on the abdomen, and the often somewhat
