boiled white of egg and potatoes, and gnawed the scales of bark among 
which they were kept. The larva3 were found at the beginning of February, 
along with newly emerged perfect beetles ; they changed to the pupa-state 
in July and August, according to their position j and some perfect insects 
emerged before the end of the latter month. Hence the authors infer that 
there are two broods of this beetle in the year. 
W. W. Saunders mentions a case in which the larvae of Dermestes lar~ 
darius attacked cork. Proc. Ent. Soc. 1866, p. viii.

BYRRHIDiE. 
Byrrlius imstulatus (Forst.) and Cytilus sericeus (Forst.) are substituted by 
Crotch as British species (Catal. & Entomologist, iii. p. 123) for dorsalis and 
vai'ius (Fab.) respectively.

Parnid^e. 
ScHiODTE (Naturh. Tidsskr. 3rd ser. iv. pp. 151-157) dis- 
cusses the position and characters of the Heterocerini, which 
he regards as forming, with the Byrrhii, Georyssii, and Parnidce 
of Erichson and Lacordaire, a single family (exhibiting a close 
similarity in the structure of the mouth and in all stages of 
their development) , their distinctive characters being merely 
expressive of the different requirements of movement and respi- 
ration in different localities and different media.^^ Heterocerus 
and its allies occupy the same position in this series of forms as 
the Bledii among the Brachclytra and the Bcaritides among 
Carabida3, and exhibit the fossorial modification of the type. 
Schibdtc refers at some length to the peculiar arched ridge on 
each side of the first apparent ventral segment, and the straight . 
ridge on the inside of the posterior femora in Heterocerini, 
which were regarded by Erichson as constituting an organ of 
sound. This view is confirmed by Schiodte, who, however, 
completes and modifies the description of the structure of these 
parts, and indicates that, whilst some of the peculiarities re- 
garded by Erichson as furnishing characters for the distinction of 
species or for the recognition of the sex of individuals fall to the 
ground, the ventral ridges may still present characters useful in 
the discrimination of some species. The most important of , 
these, in the author’s opinion, seems to be a continuation of the
