The shrilling organs in the males consist of a transparent glassy spot, bounded and traversed by strong veins, in the middle of the overlapping portion of each wing- cover, which part is proportionally much larger and longer than in the other grasshoppers; but the transparent spot is rather smaller on the left than on the right wing-cover. The male is furthermore distinguished by having two small black spots or short dashes, one behind the other, on each wing- cover, on the outside of the transparent spot. The wings are green on their front margins, transparent, and reflecting a faint pink color behind. The piercer of the female is cimeter-shaped, being curved, and pointed at the end, and is about three tenths of an inch long. The hindmost thighs, in both sexes, are. smooth and not spinous beneath; there are two little spines in the middle of the breast; and the anten- nae are very long and slender, and extend, when turned back, considerably beyond the end of the hind legs. During the evening, and even at other times in shady places, the males make a sharp clicking noise, somewhat like that pro- duced by snapping the point of a pen against the thumb-nail, but much louder. This kind of grasshopper very much resembles the Loousta agilis of De Geer, which is found in Pennsylvania and the Southern States, but does not inhabit Massachusetts, and is distinguished from our species by having the wings nearly one tenth of an inch longer than the wing- covers, the antennae excessively long (two inches or more), and the piercer not quite so much curved as in our species, besides other differences which it is unnecessary to record here. As our species does not appear to have been named, or described by any previous writer, I propose to call it Orchelimum vulgare (Fig. 77), the com- mon meadow-grasshopper, the generical name signifying literally, I dance in the meadow.
