The genus of Mole-crickets, Gryllotalpa, comprises several distinct, althougli very 

 closely allied species, the inhabitants of various countries, differing especially in 

 the number of teeth of the anterior tibiae and the neuration of the tegmina. Donovan 

 regarded them as varieties only, observing that the species here figured " differs in no 

 respect from the European species except in size and colour,"' the English mole-cricket 

 " lieing twice as large and of more of a mouse colour."

Donovan states that " the Gryllus morbillosus appears in the early edition of the 

 Systeina Naturce and the works of Roesel as an Indian species, and that Mr. Drury 

 assured him he had received it several times from Cliina. Another sort is also found at 

 the Cape of Good Hope, which is rather larger and deeper in colour than the Chinese 

 variety." 



If this be correct, it will, I apprehend, be necessary to consider these two sorts as
