E. conspersa is not rare in Denmark; Ermelund, Lundtofte, 

 Geel Skov, Donse, Frerslev Hegn, Grib Skov, Tisvilde, Jægerspris, 

 Nyraad at Vordingborg; on Lolland at Maribo; in Jutland at Sønder- 

 borg, and on Bornholm at Sandvig; the dates are ^U—^U- The spec- 

 imen from Sandvig is bred from Larentia nebulata, not earlier known 

 as host for it. It is otherwise known from pupæ of Taeniocampa 

 stahilis and pulverulenta and Larentia dilutata and the non Danish 

 L. minuta. 



Remarks: Zetterstedt only knew the species from Denmark 

 {T. ambulans), and the specimen mentioned by him is in our collec- 

 tion; it is thus certain that his ambulans is the present species. 



Geographical distribution: — Europe down into France; towards 

 the north to southern Sweden (Ringdahl). 



120. Steiniella Berg. 



Medium sized species of greyish colour. Head scarcely as broad 

 as thorax, as long or longer than high, somewhat triangular in profile,
