not on leaves only, but also on other insects, and on caterpillars as well asflies. (Report for 1843, p. 160.) Klug once found Locusta viridissimadevouring a caterpillar of Sphinx pinastri.

Hagen (Ent. Zeit. 364) has made the observation in the case of twoOrthoptera , Aeschna grandis and Gryllotalpa vulgaris, that the spinal cord[rachis] consists not of two but of four strings, two upper, and two lower,the latter alone forming ganglions, the former simple throughout. Thisagrees exactly with the researches of Newport, who, in the separation ofthe upper and lower cords, recognizes the division between the nerves ofsensation and those of motion. (Report for 1843, p. 117.)

Zimmermann’s explanation (Wiegm. Arch. Yr. 9, i, p. 390) of his state-ment about Mantis Carolina devouring Amphibia, has been copied into the‘Annals of Nat. Hist.’ (xiv, 78), but in a form so abridged that the most ma-terial points in this communication have been overlooked, in particular theadmission that the greatest part of the lizard, given as food to Iris Mantis, aswell as of the frogs, toads, caterpillars, and locusts, remained unconsumed,although none of them escaped alive. In Zimmermann’s first publishedcommunication it was expressed: “ It (the Mantis) consumed daily somedozen of flies, sometimes also great locusts, and some young frogs ; andeven a lizard of the striped sort three times its own length.” (See Bunn.Handb. Ent. ii, 538). It was this which I regarded as a joke (Rep. 1838,p. 387), and which Zimmermann, in his last communication, has in effectretracted.

Spectra. —Y. Charpentier (Orthopt. pi. 55) gives a very accuratefigure of Diapherodes gibbosa, Burm., from the specimen in the BerlinMuseum, and (pi. 56, 57) figures of Podacanthus unicolor and Bacillusaustralis, both from New Holland.

A learned essay by the same,—Observations on Lichten-stein’s treatise on the species of Mantis, in the Transactionsof the Linnsean Society of London , vol. vi, 1802,—is insertedin Germans Zeitschrift (v, p. 272-311.)

LocustarIj®. —Westwood (Arcan. Ent. pi. 70) has figured two extra-ordinary species of Phaneroptera with foliaeeous or spinous processes of thehind thighs, Ph . alipes, from Columbia, and PA. hystrix, from Mexico .

Achetai. —Eieber (Entom. Monogr. p. 126, pi. 10, f. 11) has added toNemobius another European species, Nfrontalis, new species, inhabitingBohemia and Austria .

Acridii. —Charpentier (Orth. pi. 58, 59) has figured a new genus,Coryphistes, differing from Opsomala by the thick body and the thick puffyforehead, from Xiphocera by the cylindrical form, the shape of the wings,the short legs, and minute prickles of the hind shanks. Peculiar to New
