raised lines ; and the ninth dorsal segment is deeply 

 notched, with an anal porrected lohe strongly carinated, 

 resembling a tenth dorsal segment ; the seventh ventral 

 segment is flat, and extends to the extremity of the eighth 

 dorsal segment, it is rounded and entire at its extremity, 

 and is followed by a depressed membranous plate rounded 

 at its extremity, which extends to the extremity of the 

 ninth ventral segment. Its proportions are : — Body, unc.

The four following insects differ so materially from all 

 the other apterous species, that I am uncertain (in the 

 absence of males of each) whether they should be referred 

 to the other groups of Apterophasmina, or be raised to the 

 rank of separate genera. In this uncertainty I prefer 

 leaving them under the old generic name Phasma.

The upper surface of the body is entirely obscure whitish- 

 buff varied with brown ; it is flat, opake, and very rugose ; 

 and beneath it is brown covered with minute whitish points. 

 The head is furnished on each side with a large auriform, 

 rugose-foliaceous appendage directed backwards over the 

 fore part of the prothorax, the hind part of the latter 

 being wider than the head. The mesothorax is dilated, 

 being nearly twice the width of the head ; the anterior 

 angles rounded, the sides rather contracted behind the 

 middle, and the hind part widened in front of the insertion 

 of the middle legs ; it bears on its upper surface near its 

 anterior part, two triangular, slightly elevated spaces, the 

 angles of which are directed towards the anterior angles 

 of the mesothorax. The metathorax is shorter than the 

 mesothorax and nearly square, with the outer edges nearly 

 straight. The abdomen is wide, but somewhat narrower 

 at the base than the metathorax ; each segment, from the 

 second to the sixth, furnished at the sides with lateral dila- 

 tations, which gradually increase in size to those of the 



sixth joint, which are the largest, the upper surface of each 

 marked with curved impressed lines ; the three terminal 

 segments small and narrowed ; the ninth trifid at its extre- 

 mity, exposing the extremity of the operculum. On the 

 under side the meso- and metastemum are quite flat, and 

 the dilated abdominal segments are marked with a raised 

 longitudinal carina on each side ; the whole surface being 

 covered with minute white points. The legs are rather 

 short and dilated ; the fore femora externally serrated, the 

 hind ones with two or three strong serrations near the tip ; 

 all the tibiae flattened and slightly serrated.

Entirely of an ashy colour, tinged with pale green, ob- 

 scure, subdepressed. The head very convex above, spa- 

 ringly granulated ; the crown with two conical tubercles 

 near the eyes, that on the right side being considerably the 

 larger. The antennas are slender (mutilated at the distance 

 of two-thirds of an inch from the base). The prothorax is 

 smaller than the head, with a deep transverse line close to 

 the fore margin and another across the middle ; the inter- 

 mediate space with two erect conical protuberances, the 

 hinder half sparingly granulated. The mesothorax is nar- 

 rowed at its anterior extremity, from whence it is gradually 

 swollen to beyond the middle, and subsequently slightly 

 narrowed to the hinder margin ; its surface is smooth, ex- 

 cept along the lateral margins, which are granulated, and a 

 slender raised whitish line down the middle of the back, 

 extending also along the metathorax ; near the anterior ex- 

 tremity it has several smooth raised tubercles close together 

 in the middle. The metathorax is oblong, very slightly 

 widened at the hinder part ; the five basal abdominal seg- 

 ments are dilated, elongate ovate, subdepressed, with several 

 slender raised lines, two close together down the middle of
