position of the dorsal part, and the vertical position of the lateral part of the tegmina ; 

 as well as the general colour of the insect. 



M. Brulle 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. 

 Brulle has removed this insect to the family of the grasshoppers, with long antennae, 

 (Gryllidse, Leach. Locustaires, Latr.). M. Brulle 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, (Achetida?,) for instance, the common house cricket ; and the size of the 

 palpi is scarcely a character of first-rate importance. M. Brulle has moreover 

 omitted to notice, that the anterior tibia? 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 Achetidse, regarding it as the connecting link between that family and the 

 Gryllidas. 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.
