 ORTHOPTERA. 



Cook. This is of an analogous kind to that of the Mantis siccifolia, though evidently 

 distinct. The perfect insect, and in consequence the species, is unknown to us. 

 Our only motive for inserting it is to shew the peculiar singularity of the abdomen, 

 in the middle of which there are two remarkable subquadrangular spots of a 

 filmy texture, that are transparent, and may be seen through very distinctly." — 

 Donovan. 



Mr. G. R. Gray, in his Synopsis of the Phasmidce, has characterized the last named 

 insect as a distinct species, with the description : — 



P. Donnovani (Pupa) : viride, abdomine medio maoulis duabus hyalinis subquadratis. Long. 

 Corp. 1—5. Exp. Corp. 6f. 



The chief character of this supposed insect is, I believe, indicative only of the 

 males, notwithstanding the shortness of the antennas in the accompanying figure, 

 which it is not improbable are fictitious, the antenna? of the male pupas being much 

 longer, and more numerously articulated, than in the females. If this supposition 

 should be ascertained to be correct, I have little doubt that the figure in question 

 represents merely the male pupa of Ph. siccifolium, and not of a distinct insect. In 

 the Crochard edition of the Begne Animal, a figure is given of the male pupa, which 

 is described as the perfect state of that sex ; but unfortunately only the three basal 

 segments of the abdomen are represented, the fourth, which bears the ocelli, and the 

 remaining segments being omitted.
