APPENDIX. 



DATA CONCERNING LOCAL COLLECTIONS OF GRYLLUS. 



The data given here were obtained by measuring the lengths of the 

 body, tegmina, wings, posterior femora, and ovipositor of females col- 

 lected from a number of localities in eastern United States and one in 

 Mexico. All the individuals of each collection were caught at practi- 

 cally the same time and in the same environment. Only mature speci- 

 mens are considered in this paper.

A small collection, made by Miss A. C. Dimon in August, 1903, at 

 Millinocket, in the north-central part of the State, contained 4 females.

 table 12.

Two collections, also small, were received from Miss Edith M. Patch, 

 State Entomologist of Maine. They were both made at Orono. One 

 was dated October, 1904; the other, June, 1905. Each contained 8 

 females. Table 13 shows their character.

In September, 1904, I made a collection at Perkins Cove, near York 

 Beach, in southern Maine. Grt/llus was very abundant and I easily got 

 about 175 females from an area of about 10 ares. The cove is used as a 

 landing-place by fishermen, and refuse in large quantity and variety
