REPORT ON ZOOLOGY, MDCCCXLII : 
(Bull. Mosc. 1837, V. t. 7, f. 6) draws the three joints quite correctly, 
although out of proportion, hut his account, that the third joint seems 
composed of two or three, is at all events an error. 
Bedtenhacher’s Monotoma 4^foveolatum (Col. Aust. p. 23) agrees with 
Aube’s M. 4:-foveolata. The latter (Ann. d. 1. Soc. Ent. d. Fr. 2, Ser. 1, 
p. 20, 1843) doubts the correctness of Motschoulski’s account, that he 
had discovered the same insect (1834) in Daghestan, as it was quite new 
to him when he saw it with Aube (1836). Motschoulski is annoyed 
that I should have doubted his account (Jahresber. fiir 1837, p. 208) ; 
I only placed the responsibility for it on its author. Lathridius 
costatus of the reporter, is a new species from Van Diemen’s Land 
(Arch. 1842, i. p. 202). 
PsELAPHiD^. — The reporter has published a species of this family 
from Van Diemen’s Land, Batrisus australis (ibid. p. 243). Schaum 
has discovered a Bryaxis in the salt lake at Mansfeld, which he 
described as Br. pulchella (Gene), (Germ. Zeitschr. iv. p. 192), and 
afterwards (ibid, corrections) he remarked, that it is identical with 
Br. Helferi, Schmidt (Diss. d. Pselaph.) 
ORTHOPTEEA. 
Charpentier has published three new numbers of his “ Orthoptera 
Descripta et Depicta.” 
Siebold has given a list of the Orthoptera (in LatreiUe’s sense) which 
are found in Prussia (Preuss. Prov.-Blatt. 27 Bd. p. 543). Forty species 
have been observed by him, viz., — three ForJiculidcE, three Blattce, 
three Achetidce, eleven Locustidoe, twenty Acridew. The presence of 
the Forjicula gigantea on the sea-coast of the low ground at Danzig, 
from whence it was sent to our collection by Professor Grube, is de- 
serving of notice. The author gives a very graphic account of the 
chirping of the Acridece and Locustidce. The scraping of the hind legs 
of the former against the floor has been observed not merely in Gompho- 
cerus, where each species has its own peculiar way of doing it, so that 
the individual species are easily recognised by their chirping ; but also 
in (Edipoda and Tetrix (the latter, perhaps, moving the under wings). 
In the Locustidce, the author shows, that the chirping is accomplished by 
the strong ledge-like rib of the inner margin of one elytron being rubbed 
up and down on the crenated transverse ledge of the drum of the other 
(under one). 
A very important treatise has appeared : “ Bijdragen tot de Kennis 
der Orthoptera, door Dr. W. De Haan.” It is also contained in the 
Verhandl. over de Natuurl. Geschied. der Nederlandsche overzeesche
