[StAl, C.] Systema Acridiodeorum ; essai d’une systematisation des 
Acridiodees. Sv. Ak. Handl., Bihang iv. No. 4, pp. 1-100. 
Probably the last work published by the author. Consists of a short 
introduction in French, treating upon generalities, followed by an elabo- 
rate series of Latin tables of divisions and genera, extending to nearly 50 
pages, concluding with descriptions of new species. The family is divided 
into 13 divisions, with a multitude of genera, of which very many are 
new. It appears to be impossible to characterize the genera without 
reproducing the tables ; those of them that are new are here noticed only 
by name, with the indicated types. The author in no case pays the 
slightest attention to WalkeFs genera or species, and does not even allude 
to his catalogue. 
Stein, J. P. E. F. Ueber Pachytylus migratorius und cinerascenSy 
F. Deutsch. E. Z. 1878, pp. 233-236. 
Notes on distribution, distinctive characters, &c., with cuts. The 
author maintains that cinerascens = Gryllns danicus, L., which name has 
priority. 
On dimorphic Acrydiidce, chiefly from the Mississippi Valley, affecting 
the development of the wings. In 10 or 12 species the short-winged 
forms have been placed in Pezotettix, the long in Calliptenus, although 
really not specifically distinct ; Scudder, P. Bost. Soc. xix. p. 336. See 
also G. M. Dodge, Canad. Ent. x. pp. 103-108, who says that Calliptenus 
volucris, Dodge, is a long-winged form of Pezotettix autumualis^ Dodge ; 
details are also given for the forms of P, alba and Junius, Dodge, with 
measurements. 
Ctyhippus ccerulescens. The blue wings rapidly turn red under the 
influence of phenic acid, thus becoming, in this condition, C. germanicus.

Cuculligerd hystrix, Germar. For extended notes on the stridulating ap- 
paratus, see Krauss, SB. Ak. Wien, Ixxviii. Abth. 1, p. 491, pi. ii. figs. 1-10. 
Acrydium peregrinum. Scudder, OR. Ent. Belg. xxi. pp. v. & vi., gives 
an account of multitudes of this insect that appeared on board a vessel in 
the Atlantic during a storm, and 1200 miles from land, and thinks the 
idea (held by De Selys-Longchamps) that the species may have been of 
American origin has some weight. De Selys-Longchamps follows 
(pp. vi.-viii.) by a sketch of his published notes on the species, which he 
believes is that referred to in the book of Exodus, chap. x. Cf. also
