ORTHOFTERA. 129 



A third species, also of a green color, with still narrower 

 wing-covers, which are of almost equal width from one end to 

 the other, but are rounded at the tips, and are shorter than the 

 wings, has the head, thorax, musical organs, and breast, like 

 those of the preceding species, but the piercer is much short- 

 er, and very much more crooked, being bent vertically upwards 

 from near its base. The male has a long tapering projection 

 from the under-side of the extremity of the body, curved 

 upwards like the piercer of the female. This grasshopper be- 

 longs to the genus Phaneroptera^ so named, probably, because the 

 wings are visible beyond the tips of the wing-covers ; and, as it 

 does not appear to have been described before, I propose to call 

 it angustifolia,* the narrow-leaved. It measures from the forehead 

 to the end of the abdomen about three quarters of an inch, and to 

 the tips of the wings from an inch and a half to an inch and three 

 quarters. Its habits appear to be the same as those of the oblongi- 

 folia. It comes to maturity sometime in the latter part of August 

 or the beginning of September. 



From the middle till the end of summer, the grass in our 

 meadows and moist fields is filled with myriads of little grass- 

 hoppers, of difl^^rent ages, and of a light green color, with a 

 brown stripe on the top of the head, extending to the tip of 

 the little smooth and blunt projection between the antennee, 

 and a broader brown stripe bounded on each side by deeper 

 brown on the top of the thorax. The antennae, knees, and 

 shanks are green, faintly tinted with brown, and the feet are 

 dusky. When come to maturity, they measure three quarters of 

 an inch or more, from the forehead to the end of the body, or one 

 inch to the ends of the wing-covers. The latter are abruptly nar- 

 rowed in the middle, and taper thence to the tip, which, however, 

 is rounded and extends as far back as the wings. The color of 

 the wing-covers is green, but they are faintly tinged with brown 

 on the overlapping portion, and have the delicacy and semi- 

 transparency of the skin of an onion. The shrilling organs in the 



* I formerly mistook this insect for the Locusta curvicauda of De Geer, wliich 

 is found in the Middle and Southern States, but not in Massachusetts, is a larger 

 species, with wing-covers broadest in the middle, and different organs in the male, 

 and belongs to the genus Phylloptera.
