On the Entomology of {he 



[July 



Cossyphus, both of them common to Asia and Africa, we next meet with 

 Cistela and Lagria : the latter apparently a predominant group. Pyro- 

 chroa, also, has been discovered in Java. 



HELOPID^. 



This family is the grand receptacle for the various forms of Hetero- 

 mera. Among the Indian genera we find Amarygmus, Cnodulon, and 

 Platycrepis, with .several true Helopidae, rivalling in splendour and mag- 

 nitude those of the South American Continent. 



MORDELLIDiE. 



Most of these Insects are parasites of the Hymenoptera, and abound 

 in tropical climates. Their office is probably to keep in check, and pre- 

 vent the too rapid increase of Vespidae and Bombidae : they are common 

 to the Old and New World. 



CANTHARIDiE. 

 The geographical distribution of this family is particularly interesting, 

 as it contains those Insects which are used in Medicine, and denominated 

 Blister Flies. Lytta gigas, Fab., is found abundantly in India, and also 

 in Senegal ; and there is little doubt that several species of Mylabris will 

 be found common to both continents. These vesicatory Insects of the 

 Old World are replaced in the New by the genus Tetraonyx. 



STAPHILINID^. 



By the families Notoxidae and Scydmsenidse, we arrive at the Psela- 

 phidse, and afterw^ards at the Biachelytra, which terminate the Coleop- 

 tera. Anthilephila and Notoxus occur in Nepal, and Scydmsenus in Java ; 

 while various other genera of Staphilinidse are widely dispersed through- 

 out the East. 



ON THE REMAINING ORDERS. 



Having entered fully into the consideration of Eastern Coleoptera, it 

 is not my intention at present to go into lengthened details of the re- 

 maining Orders. It is sufficient to state, that in all of them there will 

 be found similar and corresponding characters as in the Coleoptera. 

 With regard to identity of species, I cannot help remarking, that of Le- 

 pidoptera, there appear to be a much greater number of species, widely 

 disseminated throughout the world, than of any other Order. In Asia 

 and Europe we meet with Papilio Machaon, Gonepteryx Rhamni ; with 

 some species of Colias and Pontia, with Vanessa Atalanta, and Cynthia 

 Cardui ; and to these might be added, several identical Sphingidae, par- 

 ticularly Acherontia, Atropos, Deilepliila, Celerio, and Sphynx. Among
