In this useful paper, the author enters at length upo?i the nomenclature of 
alar cells and nervures, comparing the various terms employed by Meigen, 
Macquart, Winnertz, and Schiner, and especially commenting upon the latter 
author’s most recent “ Adersystem.” He establishes a formula of his own, 
founded upon Schiner’s, and gives clearly executed outlines of the wings ot 
Cordylura, Dexiiiy Leucostoma, PipuncvkiSy Syrphus, Asiliis, Odontomyia, 
Anthrax, Tipula, Dolichopm, Exechia, Ceratopogon, Mao'ocera, Sdophila, 
Ceddomyia, and Phora as types of the different forms of neuration.

Zurich : Dietrich (Ent. Bliitt. pp. 7-18) enumerates the species found in 
this Canton, in continuation of Mitth. schw. ent. Ges. ii. p. 9, giving refer- 
ences to authors, and dates and places of capture. lie also (/. c. pp. 19-21) 
gives a list of species occurring at Wallis. 
Nova Scotia : Walker (Canad. Ent. iii. pp. 141-144), in a paper headed 
“Notes on some insects of Nova Scotia and Canada,” gives a list of Diptera, 
specifying such of them as also inhabit Europe. 
Sheep-parasites : for observations on the “ tick,” “ hot,” and blow-flies, cf.

“Tsetse”: under this name, an account of an unidentified African pest 
[? Glossina morsitans, Westw.] is given in Ent. v. p. 283. 
Tusks of 2 Elephas indicus, near the base of which a mass of egg-like 
bodies, “ apparently of some Dipterous insect, and somewhat resembling 
those of Musca vomitoria^^ was deposited, are referred to by Sclater, Proc. 
Z. S. 1871, p. 146 (e/. also ‘Field,’ 12 Mar. 1870^ and Pr. E. Soc. 1871, 
p, xviii). 
CECIDOMYIDiE. 
Ceddomyia hrassicce, papaveris, destructor, nigra, and pyri, Asynapta lugu- 
hris, Diplosus pisi and tritid. Kiinstler (Verb. z.-b. Wien, xxi. Beih. pp. 48, 
38, 16, & pp. xxii, 78, 68, 38, & 24) discusses injuries to cultivated plants 
by these species. 
Ceddomyia pini. Perris, Ann. Soc. Ent. Fr. (4) x, pp. 162-170, pi. 1. 
figs. 28-31, redescribes all the stages, figuring the larva, with details, and 
supplementing the former accounts of Degeer and others. lie considers that 
the larvse are not the cause of a disease to which the young pines are subject, 
and which results* in cortical crackings, accompanied by resinous exudation, 
but that they profit by this complaint when it occurs. This sp., having 26 
joints in the antennee of its cf, and 14 in its $, should certainly form a 
separate genus, according to Perris, 1. c. p. 185. 
Ceddomyia. Perris (/. c. pp. 172-176, pi. 2. figs. 39-44, 45 & 46) describes 
all the stages of two apparently new spp., figuring details of their larvae 
(one of which has saltatorial powers) and the wings of the imago. He does 
not name these insects, which are from the Landes, and live at the expense 
of Ilylurgus piniperda and Tomicus larids. At pp. 176-185 the author
