356 REPORT ON ZOOLOGY, MDCCCXLIV. 



to make them distinct genera, some more comprehensive characters would 

 be required in connexion with those assigned. 



LATHRLDII. Mannerheiin (Germar's Zeitschr. v, 1) has given a very 

 copious and elaborate Monograph of the genera Corticaria and Lathridiiis. 

 Sixty species of the former, of the latter forty-sis, examined by himself, are 

 described with exemplary particularity. Of species previously described 

 but which he had not seen, six are given uuder the former, five under the 

 latter genus. 



[Among those given as new, or not described before, of the genus Cortica- 

 ria, there are found in western or central Europe (many of them having a much 

 wider range still), C.piligera, India, melanophthalma, cylindrica, crenicollis, bre- 

 vicollis, crocata, truncatella. C. fuscipennis is from Italy ; C. interstitialis, 

 from Lapland. Other species from Sweden, Finland, and Northern Russia 

 are, C. laticollis, lacerata, lateritia, hortensis, subtilis. The countries about 

 the Black Sea and Caspian, and the Caucasus have afforded further, C. cam- 

 picola, tit! eta, axillaris, illtesa, ^-maculata, baicalica, curticollis, taurica, 

 sutumlis, pallens, ericea, parvicollis, picipennis ; while C. intricata, diluta, 

 saginata, concinnula, gracilis, and armata, have been found only in Siberia ; 

 lastly, there are two new from North America, americana and cavicollis. 



Of the new species of Lathridius, more than the half are found in western 

 and central Europe, viz. angulatus, aUernans, incisus, clathratm, collaris, 

 nanuhis, concinnus, mgipennis, planatus, anthracinus, assimilis, scitus, brevi- 

 cornis, carbonarius, parallel-its, tantillus. L. liliputanus is Italian ; L. lap- 

 ponicus from Lapland. Sweden and Finland have added L. rariolosus 

 consimilis, gemellatus, parallelocollis ; Southern Russia and the adjoining 

 countries, L. caucasicus, volgensis, monticola, anatolicus ; from Siberia also 

 there are four, attenuatus, nervosus, carinulatus, and dubius ; and one from 

 Brazil, L. braziliensis.~\ 



ORTHOPTERA. 



Of Von Charpentier's Orthoptera descripta et depicta, 

 a 10th Number lias appeared, which concludes the work. 



The third volume of Ratzeburg's ' Forstiusekten,' treating of the 

 Hymenoptera, Diptera, Hemiptera, Neui-optera, and Orthoptera, contains a 

 variety of observations on the natural history of the Orthoptera. The 

 insects of this order are of very subordinate importance in the woodlands. 

 The Mole-cricket, if any, may perhaps deserve attention. As some suspi- 

 cions are here cast on the Locustce (Acrida?, Lch.), these should be com- 

 mended the more particularly to the protection of the forester, as they feed
