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 hind tibia? 

 are furnished with a narrow membrane. 



9th. Hindostan, with Ceylon. 



Planetica Luzara Zulama 



Corydia Meloimorpha Aprion 



Melestora Noia Phyllophora 



Phlebenotum Rhaphidophora Strongyloderus 



Pseudomops Letana Sanaa 



Deropeltis Ladnea Calanus 



Acheta Megalodon Teratodes 



Landreva Ancylecha Apalacris 



Madasumma Zulpha Leptacris 



Eneoptera Molpa Ceracris 



Tarraga Vetralla Phyllochoreia 



Phisis Tedla 



This region includes many genera remarkable on account of their 

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

 that there was a contineut 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 and 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. 

 Acheta, Landreva, Itara, Madasumma, Tarraga, Meloimorpha, Noia, 

 Letana, Megalodon, Zulpha, Molpa, Vetralla, Zumala, Strongyloderus, 

 Sanaa, Atractomorpha, Calanus, Bactrophora, Teratodes, Apalacris, Lipta- 

 cris and Ceracris only inhabit Hindostan : Achela 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. Stehodon inhabits Australasia and 

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

 in the Saltatoria.
