160 REPORT ON ZOOLOGY, MDCCCXL1II. 



instituted by Curtis, as far back as 1833, under the name of Uolopara- 

 mecus, and that Cal. Villa coincides with H. depressus, Curtis. Calypto- 

 bium instituted equally early, but not described, is recommended by its 

 euphony. 



LATIIRIDH. Aube (Ann. de la Soc. Ent. de Fr. 2 ser. i, p. 73, pi. 1) has 

 added a new species to Monotoma, M. punctaticollis, which was found 

 in the dung of sheep-stalls ; it differs from M. quadricollis in the more 

 distinct punctation of the prothorax. The author also remarks, that 

 Mon. Blaivii, Guer. (Rev. Zool. 1839), has proved to be identical with M. 

 brevicollis. 



Maunerheim (Bull. Mosc. p. 299) has formed three new species of Lathri- 

 dius, from Sitka : L. quadricollis, protensicollis, cordicollis. 



ORTHOPTERA. 



An excellent inaugural dissertation, ' Symbolae ad Orthop- 

 terorum quorundam oeconomiam/ has been given by Fr. 

 Goldfuss at Bonn. The researches of the author relate ' 

 principally, however, to the nourishment of the Orthoptera, 

 and particularly to that of Locusta viridissima and (Edipoda 

 migratoria ; and with reference to this he has seized the 

 opportunity of setting aside, by his observations, several 

 errors which have been pretty generally entertained. One 

 part of the subject relates to the food of the locusts ; some 

 earlier statements have been overlooked, and this family 

 has been usually ranked, with the Acridii, among the 

 vegetable feeders. The author shows that they do not 

 subsist solely upon vegetables, which, however, they by no 

 means wholly reject, but are partly predaceous, and possess 

 in their forelegs a great aptitude for the catching of flies. 

 Another part of the essay refers to the " proventriculus," 

 which has been regarded, especially when furnished with 

 horny ridges and teeth, as a comminuting apparatus, and 

 thence termed " a gizzard/' I have long wondered how 

 Nature could be so carelessly disregarded, for it is not easy 

 to overlook the circumstance, that the so-called " gizzard" 

 occurs only in carnivorous insects, and that it is never
