C. praecox is rare in Denmark; Frederiksberg Have, Riiderhegn, 

 Grib Skov and Tisvilde; the dates are ^'^^ — ^"/s (Nielsen, the author). 

 Nielsen has (Vidensk. Medd. fra Dansk naturh. Foren. 68, 1917, 30) 

 treated its biology (obscura); it is parasitic on Crocallis elinguaria; 

 in one host 3 to 4 parasites develop; the larva bores out, pupates in 

 the ground and hibernates as pupa; the imagines came in April. — 

 I have examined the Danish specimen of pantherina mentioned by 

 Zetterstedt 1. c. 



Geographical distribution: — Europe; towards the north to 

 Southern Sweden.
