276 THE CANADIAN ENTOMOLOGIST 



little insect is common in the short grass of dry, upland pastures at 

 Thompson's JVIills. Such localities are more or less interspersed 

 with young pines. Here I have found only the form with the 

 short pronotum {abhrroiatus). These grasshoppers are strictly 

 terrestrial, and leap about in the short, scanty grass where their 

 dull colours and mottled patterns make them very inconspicuous. 

 These insects appear to be without stridulatory powers. 



Tettigidea lateralis Burm. This grouse-locust is considerably 

 larger than the preceding, and is not uncommon at Thompson's 

 Mills. It occurs in the short grass of dry, upland fields and pastures 

 in late summer in company with the preceding species. The 

 var. polymorpha, Burm., occurs in similar situations. 



Paratettix cncullatus Burm. Among leaves on sunny, thinly 

 wooded slopes and banks near brooks, etc. Probably common at 

 Thompson's Mills. 



Xomotettix compressus Morse. Probably common at Thomp- 

 son's Mills. It occurs on banks, in pastures, open woods, etc. 



Neotettix rotundifrons Hancock. • In upland pastures and 

 sunn\-, thickly wooded hillsides. 



Tryxalis breviconiis (L) . This somewhat cone-headed Acridian 

 seems to be locally distributed and not common at Thompson's 

 Mills. I found it in only one locality among some rank meadow 

 grasses bordering a small stream. Here only a few individuals 

 were observed and these were exceedingly difficult to approach 

 or capture, owing to their shy habits and rapid flight. No note 

 has been observed for this species. 



Eritettix carinatus Scudd. I first met this little Acridian 

 early in April at Thompson's Mills, in an old pasture grown up 

 to broom grass. It does not appear to be common in this locality. 

 It keeps well down in the grass, moving about occasionally to 

 stridulate. If it leaps and alights near the top of a grass stalk, 

 it moves backward down the stalk until near the ground. Its 

 notes are faint, lisping phrases of a few seconds duration, and are 

 at intervals repeated six or eight times in quick succession: sic-a- 

 sic-a-sic-a-sic-a-sic-a-sic — sic-a-sic-a-sic-a-sic — sic-a-sic-a-sic-a-sic-a- 

 sic. This grasshopper is most active when the sun is shining. 

 Its notes resemble those of Stenobothrus curtipennis very much,
