The collection of the Academy contains no representative of 

 the male sex. 



The occurrence of this rather western tj'pe was not unex- 

 pected, as E. M. Walker recently found the species on the 

 Severn River, Ontario. 



Chorhippus curtipennis (Harris). 



Seventy specimens, about equally divided between the sexes. 

 Pequaming, July 9, 10, 14, 16, 27, 31, August i, 5, 6, 8, 9, 

 17, 21, 28, 31, September 2, 3, 5, 6 (meadow, swamp). Silver 

 Creek, August 27. Brule on mainland opposite Pequaqua- 

 waming Point, July 20 and 22. Baraga Co., August 20, 21, 24 

 and 30 (meadow, barrens near marsh). 



" This species first appeared in early July, and by the mid- 

 dle of the month was very common in all meadows of tall grass. 

 It was also to be found in brules and along roads where the 

 grasses grew high, but never in the woods. It was still very 

 plentiful when I left Pequaming (September 8th), but proba- 

 bly disappeared before the end of the month on account of the 

 cold and frosts. The males are fairly good jumpers and also 

 fly, but the females are unable to fly owing to their short 

 wings, and appear very awkward in jumping. 



" This species was never to be found in numbers except in 

 meadows of tall grass, but there it fairly swarmed, and I was 

 able at any time to take a dozen or more with a few sweeps of 

 the beating net. The males always attempted to escape by 

 jumping and flying, the females by hiding under the grass. 

 This species was by far the most plentiful around Pequaming 

 during almost the entire season." 



About one-third of the series belongs to the extremely short- 

 winged type, but quite a few intermediate between the two 

 extremes are present. The coloration shows very great varia- 

 tion, as is usual in the species. 



Mecostethus gracilis (Scudder). 



Fifty-six specimens ; fifty males, six females. Pequaming, 

 August I, 3, 5, 6, 8, 12 and 21. 



" I found this species in but one locality, where, however, 

 it was abundant for a month. It was a clearing of several
