Habitat : Virginia, Antigua, New York, Madras, and Sierra Leone (Brurij). " Tartaria et Africa." (Linn.) 



Head striped with dark and light brown. Eyes oblong. Thorax dark brown ; having a light brown 

 stripe running along it from the front of the head, which, when the wings are closed, is continued along 

 the margin of the tegmina; on the sides it is light brown, and margined beneath with stripes and spots of 

 dark buft'. Antennre thread-like, and about the length of tlie thorax. Tegmina dark buff-coloured, almost 

 transparent, variegated with stripes and spots of chfferent shapes ; those next the shoulders being nearly 

 black, and those toward the extremity more transparent. Wings very thin, and more transparent than 

 the tegmina, being of a greenish hue. Abdomen light brown on the sides ; ha\'ing a small stripe of a 

 paler colour running along it, and on the upper ridge is black. Legs pale brown. Hinder thighs 

 almost square, the outer sides being white and prettily chequered, which, when viewed by a magnifier, 

 seem like scales laid over one another; on the outside of the tibite is a round white spot, and over that 

 a long black one. Posterior tibiae brownish red, with two rows of spines on the hinder sides of a white 

 colour, and tipped with black, consisting of nine in the outer and eleven in the inner row. 



The different habitats given of this insect by Drurj', leads to believe that he had con- 

 founded several closely allied species under one name, Americanus ; which I should have 

 adopted, but for its inapplicability for the individuals of the Old World. It is also on the 

 like account that I have given the reference to Linnaeus with doubt, although Fabricius 

 cites Drury's figure under Gryllus tartaricus without any hesitation.
