Dichotrachelus rudenii Steirlin. (Suffrian) Synonymic Miscellanies, XIII M 

 on the species of Carabus — p. 91-103. (Same) Collation of some species of 

 Coleoptera, with the Fabrician types ; the genus Cantharis— p. 248-250. 

 (Same) Synonymic remarks on the genera Acalles and Scleropterus — p. 250-252. 

 The latter genus falls, being founded merely on a sexual difference more strongly 

 pronounced in certain species of Acalles. Neuroptera. — (Hagen) The 



Odonata of the Russian empire — p. 363 381. Hagen calculates the Libelluiidae 

 of Asiatic Russia at one hundred species. Russia in Europe has ninety-eight 

 species, all of which are common to it with other countries of this continent. 

 None of the Mediterranean species extend into Russia, although some of them 

 are found in the Southern part of the British islands. Eight new species from 

 the Asiatic provinces and one from North America are named, which will be 

 described in De Selys and Hagen's Monographs of the Libellulidse, now in 

 course of publication. (Same) On an Oligoneuria figured by Costa, Fauna

 various parasitic Hymenoptera— p. 103-110. . (Ruthe) On Dicelloceras vibrans — 

 p. 46-48. According to Ruthe, probably only a variety, with imperfect wings, of 

 Encyrtus platycerus Dalman. (Same) Prodromus of a Monograph of the genus 

 Microctonus — p. 219-308. Thirty-three species are characterised here, all natives 

 of Germany, of which twenty-three hitherto undescribed. Lepidoptera. — (Hey- 

 den) CheloniaquenseliiPtf */&*// and its larva — p. 184-188. (Schreiner) Remarks 

 on Tessien's Catalogue of Lepidoptera found about Altona and Hamburg— p. 110- 

 117. (Standfuss) On some Lepidoptera of the coasts of Spain and Sicily ; con- 

 tinued— p. 48-52. (Staudinger) The Lepidoptera of Upper Carynthia; con- 

 cluded— p. 37-46. (Same) An essaytowards the critical determination of the 

 known species of Sesiae of Europe and the adjoining part of Asia — p. 145-176, 

 193-254,257-288,321-338. The number of species is reduced to fifty-six, viz., 

 Trochilium 3, Sciapteron 5, Sesia 45, Bembecia 1, Paranthrene 2. (Speyer) 

 Review of Herrich-Schseffer's Lepidoptera of Europe — p. 383-385. Diptera. — 

 (Gerstascker) Essay on the Henopii — p. 339-361. The differences of sex have 

 given occasion to an erroneous multiplication of species in this family. The 

 females in general have a smaller head, broader abdomen, and longer wings. 

 Fallen appears to have known the distinction of the sexes, but he has neglected to 

 signalize these differences. Erichson has treated these as specific characters. 

 Thus Acrocera orbiculus Er. is the female of A. globulus ; Oncodes cingulaius Er. 

 the female of O. gibbosus ; while Syrphus gibbosus Pauzer should be united as the 

 other sex to O. zonatus Er., and O.fuliginosus to O. varius Er. A new genus of 

 the family, Eulonchus, is characterized, founded on an insect from California, E. 

 smaragdinus. The following are new species— Acrocera laeta from Sardinia, Ocncea 

 lugubris from Brazil. Hemiptera. — (Hagen) The Cicadas of Europe ; with a 

 plate— p. 27-37, 66-91, 131-142, 381-383. This elaborate Monograph, concluded 

 in the present volume, includes eighteen species, nearly half of which, however, are 

 properly Asiatic or African. The genus is distributed into five groups, of which 

 the first constitutes the genus Tibicen, and the last the genus Platypleura of Latreille. 

 The most comprehensive of these groups is the fourth, containing five spacies pro- 

 perly belonging to Southern Europe. The most widely distributed among these, 

 and the only one which occurs in the British Islands, as well as in Sweden, but 

 only in the southern part of either, is C. montana Scopoli, which has been described 

 under nine different trivial names. The most important synonyms among these 

 are C. hcematodes L., Fabr., Fallen, C. tibialis Latr., C. anglica Leach, Curtis, 

 C. concinna Germar. The last is a variety with clouded wings, to which also the 

 specimens of the Linnean collection are probably to be referred. Miscellaneous. —
