of Platycorynus are mentioned in the 3rd edition of the Catalogue 

 Dejean,"of which four were at the date of its publication only 

 MS. names. One of these, P. Dejeanii, has since found a de- 

 scriber in Grerstacker, I. c. The same edition of the Catalogue 

 contains three Fabrician species of OJirysochus — viz. Asiaticus, 

 pretiosus, and auratus. A single additional description is to be 

 gathered from Schonherr's Synon. Ins. i. 2. p. 235 note, Cory- 

 nodes Grondalii, Swartz, which is obviously a synonym of hifas- 

 ciatus, Oliv. The above sketch comprises everything to be found 

 in the older writers which conveys any certain information. More 

 lately we have Cory nodes pyrophorm. Parry (Umnolpus), described 

 in the Ann. of Nat. Hist. 18i4, vol. xiv. p. 454, and Trans. Ent. 

 Soc. vol. iv. p. 86, which is identical with C. ffloriostcs, Baly, Ann. 

 of Nat. Hist. 1859, vol. iv. p. 124. In Gruerin-Me'neville's Eev. Zool. 

 1841, p. 228, Chevrolat characterizes C indigaceus, from Manilla. 

 Mr. Baly has also described four other species of Corynodes 

 (decemnotatus, pulchellus, iyneqfasciatus, and pyrospilottis) in the 

 first vol. of the Journal of Entomology. In the Trans. Ent. Soc. 

 vol. iv. p. 17, Mr. Hope gives a diagnosis of EtmoTpus ignicollis, 

 from China, afterwards described as Ghrysoclms tJioracicus, together 

 with Chr. Chinensis, by Mr. Baly, Ann. and Mag. N.H. 1859. We 

 have also Chr. cobaltinus, Leconte, in vol. ix. of Eeports of Sur- 

 veys for a E-ailroad from the Mississippi to the Atlantic. T. W. 

 Harris, in Massachusetts Eeports, Insects, p. 108, has again cha- 

 racterized and figured Chr. auratus, Fab. Gebler, in the BuU. d. 

 Moscou for 1860, No. 3. p. 36, gives us Chr. punctatus, from the 

 vicinity of the Balkash Lake ; and Motschulsky, Etudes Entom. 

 ix. p. 23, has described a beautiful insect from Japan and China 

 as Chr. GaschJcevitchii. Lastly, we are compelled to omit in this 

 resume four insects indicated by Hope, in G-ray's Zool. Misc. i. 

 p. 30, but too briefly to be identified. The genus Callisma of 

 Baly is designedly passed over, as belonging, according to that 

 gentleman's present views, to a difierent group. 



With respect to the geographical distribution of the first group, 

 Corynodes, it wiU be remarked that the great majority are Asiatic. 

 The district within which they are found may be described as 

 bounded by a line drawn from the Chinese "Wall to the Indian 

 Ocean, passing through the great Gobi, or desert of Tartary, and 

 waving more or less till it emerges at some indefinite point on the 

 western coast of Hindostan, at or near Bombay. In a S.E. direc- 

 tion the species may be traced to the Philippines and the larger 

 islands of the Malay archipelago, Java, &c. as far as Borneo and
