Enipididae. 315 



Length 2—2,5 mm. 



This beautiful species is at once recognised by the colour; it 

 seems on account of Ihe uniform clothing of the thioracic disc to be 

 nearest allied to lutea. 



T. pectoralis is not rare in Denmark; Charlottenlund, Ermelund, 

 Dyrehaven, Tisvilde; on Funen at Odense and Veflinge; in Jutland 

 in Vejle Nørreskov, at Nebsager near Horsens, Hald near Viborg and 

 at Frijsenborg; fmally on Bornholm at Rønne; my dates are ^"^/c— -'/n. 

 It occurs in woods on shaded, somewhat humid piaces on bushes and 

 in low herbage, and it is a somewhate late occurring species. 



Geographical distribution: — Northern and middle Europe down 

 into France; towards the north to middle Sweden, and in Finland.
