the pronotum and wings. As in both of the preceding species, the pronotura 

 and wings are of equal length, but in this the pronotum is scarcely longer 

 than the body, and is not produced backward into such a slender point, the 

 sides being straighten The breadth is contained three times in the length. 

 It is a smaller species than the preceding. 



Length of pronotum, 0.17 inch. 



Massachusetts, Maine, New Hampshire (Scudder). 



T. rug:o!<a, Scadd., Bost. Jour. Nat. Hist., VIL 476. 



Closely allied to T. cucuUata, agreeing with it in general form and size, 

 shape and length of the pronotum, and length of the wings. The front 

 border of 1;he vertex is as" in T. cucullata, but it is broader, and the eyes are 

 scarcely as prominent. The whole surface of the pronotum, instead of being 

 delicately granulated as in T. cucullata, with the medial and marginal carinse 

 faint, has the carinse quite prominent, and the whole surface rugose, deeply 

 scarred and pitted with irregular, granulated depressions ; the wing-covers 

 are punctured as in T. granulata. 



9 Length of pronotum, 0.54 inch. 



Florida (Scudder). 



T. oxycephala, Burm., Handb. Ent., II, 659. 



The front border of the vertex narrower than the width of one of the 

 prominent eyes. Fuscous, granulose. 



Length of the body, 3.3 lines; pronotum, 4.75 lines. 

 South Carolina (Burmeister). 



T. Iiari'isii, Pack. 



This species is mentioned by Dr. Packard in Rep. Nat. Hist. Maine 

 18G1, 375-376, but I can find no description of it anywhere, and suppose it, 

 is but a synonym of one of the species before described. 



TETTICJIDEA. 



This genus, when compared with Tettix, will be found to differ in having 

 a more robust and clumsy form, a larger head, more swollen upon the top, 

 and less sloping down the front, the medial ridge in front more prominent. 

 Tlie antennae consist of 22 joints, which are cylindrical and not flattened.
