This species somewhat resembles the three preceding, but it is 

 recognised at once by the dark occiput with a bluish grey triangle; 

 it is also a little smaller. 



Remarks: I think it beyond doubt that Zetterstedt's quadrivittata 

 is the present species; his description agrees rather well, and he says: 

 "Specimina plura utriusque sexus ut frequens Daniæ incola etiam a 

 D. Stæger missa"; now all specimens in Stæger's coUection labelled 

 quadrivittata were carinfliiaca. 



H. carinthiaca is a common species in Denmark; neighbourhood 

 of Copenhagen, Ordrup Mose, Dyrehaven at Røde Bro, at Skelskør; 

 on Fænø, and in Jutland in Vejle Nørreskov, Greisdalen and at 

 Horsens, and fmally on Bornholm at Allinge and Rø; my dates are 

 '/< — '^/s. It occurs generally in or near woods, and I have taken it 

 flying in great numbers over a ditch just outside a wood. 



Geographical distribution : — Northern and middle Europe down 

 into Switzerland; towards the north to middle Scandinavia, and in 

 Finland; it occurs also in England (according to specimens sent to 

 me from Mr. Verrall.).
