STRAIGHT-WINGED INSECTS. 173 



motionless, with the legs extended in a straight line 

 resembling the lateral twigs. 



In my excursions I have never met the Walking- 

 Stick farther north than Maryland and Virginia, 

 where I have seen them in great quantities, in the 

 month of September, either standing motionless on 

 the twi^s of trees, or on the rails of fences, and at 

 my approach, they invariably took the opposite side 

 of the twig or rail in order to evade observation. — 

 The Hon. Prescott Hall, of New York, however, re- 

 cently informed me that he has observed them abun- 

 dantly at his summer residence, in Newport, Rhode 

 Island. 



The late Thomas Say held the same opinion that I 

 did, and believed this animal to be only indigenous 

 in the Southern States, until he was corrected in this 

 respect by Mr. Chas. Pickering, of Salem, Mass., who 

 informed him that he had obtained one near that city. 

 These insects are mostly all exotic, and according 

 to Westwood there arc found in the south of Europe, 

 three species ; in South America, twenty species ; in 

 North America, three species ; in Asia, forty species ; 

 in Australia, twenty-seven species, and in Africa two 



species. 



Mr. Say, in his American Entomology has given a 

 good illustration of the Spectrum femoratum, in plate 

 37, and of the Spectrum vittatum in plate 38, to which 

 I refer the reader.
