In the markings of the tegmina, form, 

 and color pellucida looks like a dimin- 

 utive Hippisciis, to which genus Cam- 

 nula is not distantly related. It varies 

 much in size and tegminal markings 

 but is not likely to be confused with any 

 other species found here. 



It is extremely common, even alnin- 

 dant locally, throughout the northern 

 part of New England, being probably 

 the most numerous in point of individ- 

 uals of any of our Oedipodinae. It is 

 found in dry, grassy pastures and other 

 untilled lands, preferably on high 

 ground. Its flight is silent or slightl}' 

 rustling, usually low, short, and direct, 

 resembling that of a large Melanoplus ; 

 when wit+i the wind, hoAvever, it is 



occasionally prolonged for several rods 

 in a straight line. 



It begins to appear in the winged 

 state about July ist and mav be found 

 during the rest of the season. I have 

 taken it from July 2 till Sept. 6. 



I have collected it at Fryeburg, Nor- 

 way, and on Speckled Mt., Stoneham, 

 Me. ; at various points in the White 

 Mts., N. H., including the summit of 

 Mt. Washington ; at Jay, Hyde Park 

 and St. Johnsbury, Vt. ; at Winchen- 

 don, Adams, and on Grey lock Mt., 

 Mass. ; a single specimen (on a rainy 

 day) at So. Kent, Ct., in the extreme 

 western jDart of the State, and several 

 at Thompson, in the extreme north- 

 eastern part. In the latter place it was 

 not uncommon in a locality on the north 

 side of a high drumlin a mile east of the 

 village. I have also received it from 

 Hanover, N. H. (Weed) ; and Floi'ence, 

 Mass. (S. W. Denton). 



15. Hippiscus Sauss. 



Hippisciis Saussure 1S61. Rev. et 

 M:ig. de Zool., xiii, 398, (1S61). 



A genus of locusts ot large size and 

 robust form represented in New Eng- 

 land by two species, one common, the 

 other extremely rare but occurring more 

 plentifully in the South and West. 

 Mr. Scudder has recently published a 

 revision of this genus (Psyche (1S92), 

 p. 265 et seq.) .
