pand 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 pronotuni is prolonged beyond the abdomen, 

 and the antennte are thirteen to fourteen-jointed, wliile Tetti- 

 gidca differs from it by liaving twenty-two-jointed antennae, and 

 a thiclver, shorter bod3^ Tettix gramdata Kivhy has a verj- 

 prominent vertex, with the front border angnlated. 



Tettigidea lateralis Say is a conunon species, and may be 

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

 tumn. It is pale brown, with the sides of the bodj' blackish ; 

 the prothorax is yellowish clay colored, and the fore wings 

 have a small white spot at the tips. 



Batrachidsa has but twelve joints to the antennae, and other- 

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

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

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

 arched, and on each side 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. Saussure 

 describes an aquatic Tettix from Ceylon. 



Tiie 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 antenuie are 

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

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

 Brazil at Para. 



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

 gish insects found 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 and linear, and the wings either aborted and 

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

 long, while the antennae are rather short, and the abdomen is 

 nearly twice as long as the rest of the bod}-. 



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.
