panel two and a quarter inches ; those of the female three 

 inches. Mr. Scudder has discovered a chalcid parasite in the 

 eggs of CEdipoda Carolina. 



In Tettix the pronotum is prolongeel beyond the abdomen, 

 and the antenme are thirteen to fourteen-jointed, while Tetti- 

 (fidea differs from it by having twenty-two-jointed antennae, and 

 a thicker, shorter body. Tettix granulata Kirby has a veiy 

 prominent vertex, with the front border angulated. 



Tettigidea lateral! s Saj* is a common species, and may be 

 found, like all the other allied species, in the spring and au- 

 tnmn. It is pale brown, w r ith the sides of the boely blackish ; 

 the prothorax is yellowish clay colored, and the fore wings 

 have a small white spot at the tips. 



Batracludea has but twelve joints to the antenna?, and other- 

 wise differs from Tettix in its more compact shorter boely, and 

 more distant eyes, while the mesial crest on the prothorax is 

 very high. In B. cristata Harris the crest is high, regularly 

 arched, anel on each siele of the prothorax are two shallow 

 grooves ; the surface is rough, with a dark squarish spot on 

 each side above the terminal half of the fore wings. Sanssure 

 elescribes an aquatic Tettix from Ceylon. 



The genus Proscopia is wingless, with the front produced 

 into a long slender cone, while the whole body is long and 

 cylindrical, somewhat as in Diapheromera. The antenna? are 

 very minute, six to eight-jointed, and the legs are long and 

 slender. P. yigantea Klug is six inches long, and occurs in 

 Brazil at Para. 



PHASMIDA Leach. The Walking-sticks, or Spectres, are slug- 

 gish insects founel on twigs and leaves, to which they bear a 

 strong resemblance, and are neither raptorial as regards their 

 fore legs, nor leapers, like the grasshoppers. Their bodies are 

 remarkably long anel linear, and the wings either aborteel anel 

 very small, or strikingly leaf-like. The head is horizontal, 

 long, while the antenna? are rather short, and the abdomen is 

 nearly twice as long as the rest of the body. 



The subgenital plate is formed by the largely developed 

 eighth sternite, while the ninth segment is incomplete, the 

 sternum consisting of a membranous fold. According to L.
