368 Tachinidae. 



Female. Similar; thorax a little more pruinose. Fourth abdominal 

 segment in my specimen with only a pair of discai bristles. 



Length 4,5 mm. 



A. ocypterina is very rare in Denmark, I know only one female, 

 labelled Brænderup, August 1880. The above description of the male 

 is drawn from a French specimen, kindly sent me from Dr. Villeneuve. 

 The species is known as bred from Pterophorus microdactylus, tephro- 

 dactylus and the non Danish lithodactylus. 



Geographical distribution: — Europe down into France; to- 

 wards the north to middle Scandinavia, and in Finland. 



Remarks: My specimen has yellowish squamulæ and is thus a 

 variety, while the squamulæ are generally white.
