and the most familiarly known of all. The best-known species, M. retinervis, 

 is over 2 inches long (from head to tip of folded wings) ; the overlapping 

 dorsal parts of the wing-covers form a conspicuous angle with the lateral 

 parts, hence the name "angular-winged." The ovipositor of the female is 

 very short, strongly curved, and with a bluntly pointed, finely serrate tip. The 

 song of M. laurifolium (Fig. 203) is said to sound like tic repeated from 

 eight to twenty times, at the rate of four a second. The eggs, of which each 

 female lays from 100 to 150 in the fall, are grayish brown, flat, and long- 

 oval, about \ inch long by \ inch wide, and are glued in double rows along 

 twigs or on the edges of leaves (Fig. 199). I have found them on thorns 

 of the honey-locust, and Howard once received "a batch from a western 

 correspondent which was found on the edge of a freshly laundried collar 

 which had lain for some time in a bureau drawer." The rows are side by 

 side, and the flat eggs overlap each other in their own row. The young 

 hatch in spring and, slowly growing, moulting, and developing wings, reach 

 full size and maturity by the middle of the summer.

The narrow-winged katydids, belonging to the genus Scudderia (Figs. 204- 

 206), are smaller than the broader- winged kinds, being not more than i 

 inches in length to tip of folded wing-covers, and the wing-covers are narrow 

 and of nearly equal width for their whole length. The ovipositor is broad,

compressed, and curves sharply upward. These insects frequent shrubbery 

 and bushes, or coarse grasses and weeds along ravines or ponds; also 

 marshes, cranberry-bogs, and similar wet places. Their flight is noiseless
