Atlantic. Microgryllacris and Natricia inhabit Australia. Callimenellus 

 and Lucera are of China. Trigonopteryx inhabits Australasia; the fore 

 wings of this genus have a remarkable resemblance to dead chipped leaves. 

 Mastax inhabits Australasia and South America towards the Atlantic. 

 Scelymena inhabits Hindostan and Australasia ; this is the only amphibious 

 or semi-aquatic genus of Dermaptera; it dives readily and the hiud tibiae 

 are furnished with a narrow membrane.

This region includes many genera remarkable on account of their 

 size or of their peculiar structure ; it has been supposed from observations 

 that there was a continent formerly extending from Ceylon to the islands 

 of Australasia before the appearance of the southern part of Hindostan. 



Planetica, Corydia, Deropeltis, Phisis, Rhaphidophora, Ancylecha, 

 Tedla, Aprion and Phyllochoreia inhabit Australasia. Corydia and 

 Deropeltis are distinguished by their resemblance to beetles. Rhaphido- 

 phora is of large size and probably inhabits caves. Phyllochoreia has an 

 extraordinary likeness to a leaf. Melestora and Lazura inhabit South 

 America towards the Atlantic. Phlebenotum and Phyllophora inhabit 

 Australasia aud Australia. Pseudomops and Eneoptera inhabit Australasia, 

 South America towards the Atlantic and Central America ; the species of 

 the former genus have much beauty and elegance and resemble beetles.

 cris aud Ceracris only inhabit Hindostan : Acheta is an example of the 

 greatest development of the cricket-tribe; Monticollis, the name of the 

 only species of Teratodes, expresses its peculiar structure ; Meloimorpha 

 has much resemblance to a beetle. Steirodon inhabits Australasia and 

 South America towards the Atlantic, and its species are some of the largest 

 in the Saltatoria.
