Both were taken from beneath rocks in stone piles ; one in 

 damp woods, the other in a dry, open field. 



Encoptolophus sordid us I Sunn, at this season occurs almost 

 entirely in the sunny pastures and grass fields of dry, upland 

 localities. This locust appears to be the hardiest and most 

 active species at this season, and is rather difficult to capture 

 owing to its strong powers of flight. Like many other locusts, 

 this species stridulates only during flight, producing an unusu- 

 ally sharp, vigorous rattle, as it dashes across the fields. I cap- 

 tured many males of this species as I walked over the fields. 

 If one is disturbed, it darts in a swift, straight flight some rods 

 away with a noisy rattle. This locust is very common in all 

 dry upland situations. 



One of the smallest and noisiest locusts occurring at this 

 season is Stenobothrus curtipennis Harris. Its notes are heard 

 only during the sunny hours of the day, in pastures, fields, and 

 in open, sunny places in the woods. These notes are frequent, 

 short, lisping phrases, of several seconds' duration, produced 

 by the sawing of both legs simultaneously upon the outer edge 

 of the tegmina. This small locust is one of the commonest 

 species at this season. 



At this late season of the year it is very unusual to find an 

 Orchelimum. I was successful in finding but one individual 

 of Orchelimum agile DeGeer. I took this, one sunny afternoon 

 late in October, among some low-land grasses in a sheltered 

 pasture swale. T had been searching for specimens of Nemo- 

 bins palustris when I heard the faint note of an Orchelimum 

 near at hand. The insect was so chilled and enfeebled that it 

 merely fell into the grass unable to leap when I reached down 

 to grasp it. Its song was so brief and feeble that it was audible 

 but a few feet away. 



Among the late autumn insects, Grylhts pennsyhanicus Bur- 

 meister is one of the commonest and most musical crickets in 

 New England. As soon as the morning sun has warmed the 

 fields, great numbers of the males and females of this species 

 may be seen traveling about in all upland fields and pastures. 

 The gravid females are concerned with the sole function of ovi-
