CATALOGUE OF ORTHOPTEROUS INSECTS. 



elongated, pointed, and bifid at the tip ; whereas in the 

 Australian Ph. Caprella, the Manilla Ph. longicorne, and 

 the New World species allied to Ph. gracile, it is of the usual 

 shape, and in the Brazilian Ph. LePeletierii it is greatly 

 elongated : on the other hand, the females of Ph. Pytho- 

 nius have the oviduct twice the length of the three terminal 

 segments of the body, and in Ph.Le Peletierii, fern., it ex- 

 tends a short distance beyond the extremity of the abdo- 

 men ; whilst in PA. Acanthopus, fern., it is not visible at all 

 from above, the terminal dorsal segment being truncated. 

 Corresponding variations may possibly be simultaneous in 

 both sexes of the different types of form, but they do not 

 appear to be concurrent with the geographical distribution 

 of tbe species. The males of some of the smaller species 

 approximate very closely to some of the more slender 

 species of Neeroscia, and it is not improbable that it will 

 be found necessary to remove them to that genus or to 

 Phasma, should their females prove to be winged. 



In the uncertainty which exists as to the apterous or 

 winged condition of the females of the types of the genus 

 Cladoxerus (CI. serratipes, gracilis, &c), I have preferred 

 retaining the generic name given by Mr. G. R. Gray to the 

 male of the Brazilian species (Ph. Le Peletierii). Hence, if 

 these females should ultimately prove to be winged, it will 

 be necessary to remove them from the genus and restore 

 to them the generic name of Cladoxerus.

I have adopted the usual plan, where the sexes of a spe- 

 cies have been described under different names, of retaining 

 that of the male in preference to that of the female, although 

 the latter has been employed for both the sexes by Bur- 

 meister and Charpentier. I have the greater pleasure in 

 doing this, as commemorative of the name of my late friend 

 the Count Le Peletier de Saint Fargeau, one of the most 

 ardent and laborious of entomologists. 



The elongated operculum of the male, with the remark- 

 able arrangement of the chief veins of the costal area, are 

 characters which I have not observed in any other species 

 of the family.

Burmeister suggests the possibility of this insect being 

 identical with the following, which he has described under 

 the name of Bacteria aurita. No two species can, how- 

 ever, be more distinct, as will appear from the amended 

 diagnoses which I have given of each.
