The variations in the structure of the antennfe of these species are 
described and figured. A larva is described and figured by R. Osten 
Sacken, tom. cit. pp. 84-87, which is referred to Pleocoma, but with no 
attempt at evidence of its really belonging to that genus. Its mandibles 
change after moulting. This larva seems to oscillate between the Tro- 
gides and Geotrypides, inclining to the former.
