dorsal part, and the vertical position of the lateral part of the tegmina ; as well as the 
general colour of the insect. 
M. Brull6 has very judiciously formed this insect into a new group, which he has 
named Schizodactylus, from the remarkable structure of the tarsi, which are furnished 
with curious dilated plates, and are four-jointed. It is chiefly on this account M. 
Brull6 has removed this insect to the family of the grasshoppers, with long antennae, 
(Gryllidae, Leach. Locustaires, Latr.). M. Brull6 has also been induced to adopt this 
arrangement, by the greater length of the maxillary palpi, and the large size of the 
wings. The last mentioned character is, however, especially that of many of the 
crickets, (Achetidae,) for instance, the common house cricket ; and the size of the palpi 
is scarcely a character of first-rate importance. M. Brull6 has moreover omitted to 
notice, that the anterior tibiae are destitute of that peculiar oval cavity which he 
expressly states (p. 125) to be found “ dans tons les insects de cette famille.” Hence, 
from the majority of its characters, I am still induced to place this insect in the family 
Achetidae, regarding it as the connecting link between that family and the Gryllidae. 
The genus Anostostoma of Gray, ( Mag . Nat. Hist. 2nd series, 1. p . 143.) is another 
very interesting link.

“ The only specimen we have ever seen of this elegant species, is that delineated 
in the annexed plate with Locusta citrifolia. This insect was received from Amboyna 
some years ago by Governor Holford, then resident in India, and is at this time in the 
collection of the author.
