only for the width of the articulated styles at the end of the abdo- 

 men of both sexes, but for the shortness of the elytra and wings 

 in the female. There is little or no difference in the length of the 

 male and female individuals ; but the males are perceptibly more 

 slender in body, head, and raptorial fore-legs. There is another 

 species with equally wide styles and of the same size, but having 

 the much longer elytra of the female with the proportion to total 

 length of T W, distinguished also by the whole of the erytra being 

 of the same brown color, imperfect transparency, and coarse veins 

 of the anterior margin, for which the name Mantis fusci-elytris 

 might be suggested. The two small dark spots on the elytra of 

 M. latistylus are more frequently absent than present, and in some 

 of our specimens there is one on one side and two on the other. 

 This curious Mantis has not been figured before.
