Ccphus pygmmts. Wallschlegel communicates (Mitth. Schweiz, ent. 
Gesellscli. ii. pp. 16.3-156) a note on the occurrence and natural history of 
this insect, which, in 1860, inflicted much injury on the crops in the Aargaii. 
Stierliii appends some remarks to this paper (/. c. pp. 156-167).

Tenthredinida?. 
E. Norton has commenced (Trans. Amer. Ent. Soc. i. pp. 
31-84 & 193-324) a descriptive catalogue of the North- Ame- 
rican species of this family. In the preliminary portion he in- 
dicates the general classification of the Hymenoptera and the 
terminology of the Tenthredinidse, and gives a tabular synopsis 
of the genera belonging to the Tenthredinidse and Uroceridse. 
Of the former he recognizes 63 generic groups ; but 2 of these, 
formed by sections of King’s genus Hylotoma, do not receive 
generic names. In the catalogue itself the genera and species 
are all characterized, and the latter sometimes tabulated. 
Snellen VAN VoLLENHOVEN (Tijdschr. v. Entom. 2^® ser. i.) describes and 
figures all the stages of the following species : — Macrophya alhicincta (Schr.), 
pp. 189-195, pi. 7 ; Phyllotoma melajio^njga (K\w^), pp. 196-201,. pi. 8 j and 
a new species of Nematus. 
Frauenfeld notices (Verh. zool.-bot. Ges. in Wien, xvii. pp. 783-784) 3 
species of this family of which the larvae occurred in great numbers in 1867. 
One of these fed upon various species of Iris ; another was Hylotoma 
herhet'idis ; and the third fed upon various species of Rmnex, 
Healy describes (Ent. M. Mag. iv. pp. 106-107) the natural history of a 
species of Thyllotoma (P. aceris, M‘L., vide infrci), the larva of which mines 
the leaves of the maple, and constructs for itself a small circular case from 
the upper and lower membranes of the leaf in which to pass the winter and 
undergo its metamoiphosis. The species is identifiedbyM‘Lachlan(/.c. p. 123) 
with P. ace7’is (Kalt.) described in his paper on the German phytophagous 
insects. 
F. Low (Verh. zool.-bot. Ges. in Wien, xvii. pp. 747-748) gives further 
details on the construction of the larva-sac of Lyda inanita (Vill.) in correc- 
tion of his former statements. He figures a rose-leaf with the sac attached 
to it, to show the mode in which additions are made.
