PHASMID^E. ANISOMORPHA. 



1!) 



The National Museum in Paris contains several speci- 

 mens of this species, which I have examined, and which 

 differ considerably from each other. The specimen repre- 

 sented in M. Gay's work is a large female, which bears a 

 strong general resemblance to, and has rudimentary teg- 

 mina as fully developed and the abdomen as gradually 

 attenuated as in, the female of An. pardalina. Others, of 

 a much narrower form, with the sides of the body nearly 

 parallel, have the hind margin of the mesothorax dilated at 

 each side, with a deep rounded notch in the middle. These 

 are evidently males, the largest measuring as follows : — 

 Head, 2 lines ; prothorax, 2\ lines ; mesothorax (to extre- 

 mity of lateral scales), 3£ lines ; metathorax, 3 lines ; ab- 

 domen, 1 1 lines : total, 23 lines. 



Another specimen, which is evidently a female, measures 

 more than half an inch longer than the specimen figured 

 in M. Gay's work, its dimensions being :■ — Head, 2 lines ; 

 prothorax, 3} lines ; mesothorax, 4 J lines ; metathorax, 

 4i lines ; abdomen, 18 lines = 33 lines, or 2f inches. It 

 has the thoracic portion of the body considerably narrower 

 than the female figured by M. Gay ; the prothorax is 

 nearly square and smooth ; the mesonotum rather oblong 

 and only slightly emarginate behind, without any decided 

 indication of the rudimentary wing-scales ; the metanotum 

 rather oval, and the abdominal segments gradually atte- 

 nuated to the tip. From these characters there seems to 

 me to be reasonable doubt whether this specimen, from 

 its larger size, can be a female of this species with the 

 wing-covers undeveloped. I should be rather inclined to 

 consider it as a distinct species, for which I would propose 

 the provisional specific name of An. yrylloides.

The only specimen I have seen of this species is a very 

 imperfect female in the National Collection. It is jet-black, 

 impunctate, very glossy, and has the head and hind legs 

 pitchy ; it is smooth, and destitute of spines or tubercles. 

 The head and prothorax are of nearly equal size ; the former 

 has the sides behind the eyes nearly straight, and the 

 crown of the head is marked with two impressions between 

 the eyes. The prothorax is slightly margined at the sides, 

 the anterior angles spiraculiferous. The mesothorax is 

 gradually widened from the anterior margin to the middle, 

 from whence to the base the sides are nearly parallel ; it is 

 impressed on each side within the lateral margin and 

 slightly in the middle of the disc ; the hind margin is 

 straight, and destitute of rudimentary wing-scales. The 

 metathorax is as broad as the widest part of the meso- 

 thorax, subconvex ; the lateral margin constricted rather 

 before the middle, exposing the dilated flanks of the meta- 

 sternum. The abdomen is gradually narrowed from the 

 base to the extremity ; the three terminal segments are 

 arched above, the ninth being obtusely rounded and ex- 

 posing the extremity of the operculum, which extends 

 beneath the three terminal joints ; the two anal styles are 

 very short and ovate. The four fore legs are wanting ; the 

 two hind ones are short, strong and simple.
