THE DISTRIBUTION OF INSECTS IN NEW HAMPSHIRE. 363 



me to inhabit the state, adding notes upon their geographical distribution 

 both within and without the state. Such information is given concern- 

 ing the mode and character of their stridulation as could be obtained. 

 Unfortunately most of the material for the list has been collected about 

 the White Mountains only in excursions made by my friends and myself. 

 This accounts for its poverty. 



GRYLLIDES. 



1. Gryllotalpa borealis Burm. [Plate A, Fig. 7.] The northern mole- 

 cricket inhabits nearly the whole of the United States east of the great 

 plains, from Louisiana to Massachusetts. It has not yet been discovered 

 in New Hampshire, but it will doubtless be found in the southern portions 

 of the state, as it is not at all uncommon in the region about Boston and 

 Springfield, Mass., and has been taken by Prof. Verrill, at Anticosti. The 

 figure has been introduced upon the plate, to call the attention of those 

 interested, and because it is one of the most peculiar forms among 

 Orthoptera. It is a burrowing insect, as the character of the forelegs 

 readily indicates. At Winter pond, Winchester, Mass., the whole surface 

 of the ground beneath the sod and stones for a rod from the water's edge 

 is completely honeycombed with their burrows. They seldom penetrate 

 to a depth of more than six or eight inches, rarely to a foot beneath the 

 surface. The burrows are usually about a third of an inch in diameter, 

 entirely irregular in direction, and often terminate abruptly. Where the 

 ground is hard the burrows are brought so near the surface as to raise 

 long ridges of mould, which, when dry, frequently fall in and expose 

 the burrows. The note of this insect is most frequently heard at dusk, 

 and resembles the distant sound of frogs, but is somewhat feebler. 



2. Gryllus luctuosus Serv. This insect is readily distinguished from all 

 other species of the genus found in this part of the country by the great 

 length of the wings, which extend far beyond the body and the elytra. It 

 has been taken in New Hampshire by Mrs. F. W. Putnam, and is not 

 infrequent even so far north as the valleys of the White Mountains. The 

 individuals from this locality are much smaller than farther south. 



Other species of this genus doubtless occur in New Hampshire, but I 

 do not happen to possess specimens for determination. At Jefferson, in 

 1867, no chirp of a Gryllus was heard until August 12, although they 

 often commence their song in Massachusetts in June.
