CATALOGUE OF ORTHOPTEROUS INSECTS. 



Genus 18. DIAPHERODES. 



Diapherodes, pars, G. R. Grin/. 



Diapherodes, De Haan (p. 109). 



Diapherodes, Sect. B., pars, Burmeister (p. 5/4). 



Body more or less spiued ; that of the male long and 

 slender, furnished with oval tegmina nearly as long as the 

 metathorax, and large wings. Body of the female broad 

 and subdcpressed, with oval tegmina and rudimental wings. 

 Legs strong and angulated. Ovipositor of the female boat- 

 shaped, and extending beyond the extremity of the abdo- 

 men. Anal styles very minute. Ocelli wanting. 



Natives of tropical parts of the New World. 



I have here restricted the genus to the large species, of 

 which an excellent figure of the female was first published 

 by Drury under the name of Mantis gigas, the natural 

 history of which has since been investigated in the Island 

 of St. Vincent's by the late Rev. Lansdown Guikling, whose 

 specimens of both sexes, with the eggs and larvee, are pre- 

 served in the British and Hopeian Museums ; to this is 

 added the Platycrana venustula of Serville, and a third 

 West Indian species. 



The other species introduced into the genus by Gray 

 appear to differ in no generic respect from his Aplopus mi- 

 cropterus. It seems to me to be most probable that the 

 PlcesiojjhyUum Hnvaniense of MacLeay's MSS. {Phasma 

 n., ante, p. 34, Plate XXII. fig. 7) may be the full-grown 

 female of PI. venustula, or an allied species ; in which 

 case, we shall have females of the group without any rudi- 

 ment of wings or wing-covers. The peculiar manner in 

 which the horns of the head are developed in the female of 

 this insect indicates au intimate relationship with the fe- 

 males of Ilaplopus.
