Ceuthophilus neglectus Scudder. (Diagnostic note.) This 

 species differs from all our other New England species in the struc- 

 ture of the abdomen of the male and can usually be recognized at 

 once by the yellowish color of the underparts, and the following 

 points : the ninth " tergum is usually completely hidden by the 

 crescentically thickened parabolic hind margin of the eighth tergum; 

 the subgenital plate is also distinctive,^ — short, scoop-shaped, with 

 thickened, semicircular, nearly horizontal margin. 



Nemobius griseus E. M. Walker. I have taken this cricket 

 sparingly on sandy tracts at Brunswick, Me., Provincetown, and 

 South Sudbury, Mass., in September. 



Nemobius maculatus Blatchley. Mr. B. H. Walden has sent me 

 this species from New Canaan, Conn., taken in September. 



Gryllotalpa vulgaris Latreille. I found three examples of this, 

 the common European mole-cricket, in the collection of local insects 

 of the Maria Mitchell Scientific Association at Nantucket. They 

 were without data but believed to have been taken on the island. 

 This is highly probable, since another European orthopteron, a 

 flightless bush-katydid, Leptophyes punctatissima, has been cap- 

 tured there by Prof. H. T. Fernald. Both species were doubtless 

 introduced in commercial importations of plant material from 

 Europe, such as Scotch broom, pines, and heather. 



Acrydium granulatum incurvatum Hancock. This is the western 

 broad-shouldered form of our common Angulate Pygmy or Grouse 

 Locust. Mr. C. W. Johnson has taken examples at Capens and 

 Sugar Island, Moosehead Lake, Me., in July. 



Acrydium hancocM Morse. This robust ally of our common 

 Ornate Pygmy Locust, described from and common in Iowa, I took 

 at Randolph, N. H., in July, 1898, and in the summer of 1913 found 

 it at Fort Kent, Fort Fairfield, and Houlton, Me., August 24 to 

 28. 



Acrydium arenosum angustum Hancock. This Pygmy Locust is 

 well-distributed in New England. I have taken it at various 

 points from Cherryfield in eastern Maine, and Newport in northern 

 Vermont, to Nantucket, Mass., and New Haven, Conn.
