broader than the subcostal cell, and the thickening as in the male 

 stretching to the end of costa. 



Length 1,4 to nearly 2 mm. 



A. crassicosta is somewhat rare in Denmark, I have taken it in 

 only two localities, Ermelimd from ^Ve — ^'/e in 1918 to 1920 and on 

 Langeland at Lohals from ^/t — ^V? in 1920, and a single specimen 

 was taken on Bornholm at Rø in July 1883 (H. J. Hansen); in Erme- 

 lund I took it in some numbers on bushes and in low herbage, chiefly 

 consisting of Aegopodium podagraria, in a hiimid, shaded place in 

 the wood. 



Geographical distribution: — Besides from Denmark it is known 

 from Styria. 



Remarks: The male was hitherto not described; it is interesting 

 to see that in this species also the male has a thickened costa, only 

 to a less degree than the female, while in the species with the costa 

 moderately swollen in the female, the male shows no thickening; 

 this does, however, not seem to be the rule, for Wood describes the 

 male of costalis without mentioning any thickening of the costa. 

 I have no doiibt that my species is correctly determined as it agrees 

 very well with Strobl's description; Strobl's species is thus a good 

 species and not synonymous with costalis as it was hitherto considered.
