of species, assisted by modifications of the genital organs, of which a new 
feature, in the shape of a plate with palpi and pedicel, is described and 
figured. A peculiar apparatus is found in the proven triculus [c/. Zool. 
E,ec. xii. p. 361] of the last 7 of the above-named groups, but never occurs 
in the first 5 of them ; and all these groups are characterized by various 
different features in the structure of the copulatory and digestive 
organs. The Tomicides are raised to the rank of a family, with 4 sub- 
families, CryphaloidecR^ Tomicoidece, Dryoccetoidece, and Xyleteroide(E, 
characterized by similar modifications. 
The European Cryphaloidem consist of Ernoporus, Stephanoderes, Cry- 
phalus, HypohoruSyPityophthorus^ Pseudocryphalus, Xyloctonus, Hylocurus^ 
and — 
Homceocryphalus, g. n., p. 168, note ; funiculus 4-jointed, suture of club 
quite straight, above and below. For H. ehlersi, sp. n., not described. 
The genus Ernoporus is then very minutely discussed, with observa- 
tions on points of internal and external anatomy (which are in many 
cases also figured), both generally, and as regards E. liliot}, F., fagi, N., 
caucasicus (sp. n., pp. 373-377, figs. 49-53, Piatigorsk, N. Caucasus), and
