Campylochaeta obscura Fall. 
Parasitic in the caterpillars of Crocallis elinguaria L.; in one 
host 3, in another 4 fullgrown maggots. No eggs on the skin of 
the host. The funnels originate from the skin in the closest vicinity 
of the spiracles. Pupation in the earth; the puparia hibernate. 
Tachina rustica Fall. 
Has been bred in June from the larvæ of an undetermined 
saw-fly feeding in September on clover. The :maggot penetrates 
into the host through a hole in the bottom of the egg shell (,c0- 
quille indéhiscente", J. Pantel), and the primary funnel originates 
from the borders of this hole. The host moults shortly after the 
penetration of the maggot and the maggot hibernates in the first 
Stage, 
Goniocera enigmatica Villen. & Niels. 
It is well-known that the young caterpillars of Malacosoma ca- 
Strensis are to be found in clusters on grass and other low her- 
bage. In spring 1916 it was found at several occasions that one 
Or two females of the Goniocera had penetrated into these clusters 
and were lying amidst the caterpillars quite surrounded by these. 
Some of the flies were put into a breeding cage together with 
Some caterpillars. The next day some of the caterpillars were 
Opened, and small maggots were found in them; these maggots were 
fully agreeing with the maggots in eggs dissected out of the flies.
