2. Hind coxae not excavated; pygidium not exposed.

3. Hind coxae excavated for the reception of the thighs ♦ 
DERMESTlDi®. 
c. Ventral segments 5 ; first three joints of tarsi dilated. 
Nitudulid^e. 
B. Wings membranous, with distinct veins, and mostly suitable 
for flight, but in some genera wanting or undeveloped ; 
ventral segments G or more in number. 
a. Elytra with distinct veins .... Silphid^e.

With the Mycetophagidae are to be included the Colydiadaej 
Cryptophagidoi, TrogositidcBy Peliidmy Thonctid(H, Mycetmdcp, 
Murmidiid(jp, Lathridiidm , Monoto7nid(B, Derodontid(S, and 0th- 
7iiid(B ; and with the DermestidcR, the Byrrhidm and Tkroscida. 
From Leconte^s note at p. 252, it would seem that this Table, 
though recent, is of a provisional nature only. 
J3old (Ent. Mo. Mag. v. p. 246) notes the occurrence in Northumberland 
of Eucomms fimetarius (Thoms.). Ilye (ibid.) adds other localities for the 
species. 
Baudi (Berlin, ent. Zeit. xiii. p. 416) mentions Sardinian vars. of Scyd- 
mccnus hmzci (Qen6) ; and also the habits and varieties of Leptomastax hypo- 
yarns (Pirazz.).
