Allophora. 95 



A. hemipterah rather rare in Denmark; at Copenhagen (E. Olsen)^ 

 Dyrehaven (Drewsen, the specimen mentioned by Zetterstedt) ; in 

 Jutland at Sønderborg (Wiistnei), in Greisdal (Schlick) and at Hald 

 (C. Larsen), and on Bornholm in Almindingen (Schlick). The dates 

 are ^/g — ^"/s? on the latter date it was taken in copula. Nearly all 

 our specimens belong to the normal form {vittata), only one (from 

 Greisdalen) belongs to var. obscura and one (from near Copenhagen) 

 to var. eximia. 



Geographical distribution: — Europe; it does not seem known
