Dr. Zaddach resumes the task of elucidating the known European 
species, commenced by himself and Herr Brischke ten years ago in the 
same medium of publication. He gives a supplement to the original 
bibliographical references, and a continuation, to the beginniug of 1876, 
of works, papers, &c., on the Tenthredinidoe. 
The Nematidce are discussed, and defined as including all species of 
which the larvae have only 10 pairs of feet (3 pectoral, 6 ventral, and 1 
posterior), comprised in the following genera ; Nematus, Cryptocampus^ 
Leptopus, Cladius, Dineura^ . and Leptocerca. The species of Nematus 
proper are then divided into 24 groups, according to colour-differences, 
and the following described, the larvae being in most cases figured : — 
Nematus ahdominalis^ Pz. (ventralis, Htg., nec Pz., which is a Selandria),
