* ' Common almost everywhere except in the woods. After 

 August ist the mature specimens were most plentiful, espe- 

 cially in meadows and damp places, and their ' ' creeeeeeeeeeeee' ' 

 or " creee-creee-creee-creee" could be heard on every side." 



Of the above-mentioned series but four specimens, two 

 males and two females, belong to the long-winged type. As 

 is usual in this species, a great amount of color variation is 

 noticed in the individuals examined. 



Gryllas pennsylvanicas Burmeister. 



Fifty-six specimens ; thirty-five males, twenty-one females, 

 one nymph. Pequaming, July 3, 18, 22, 28 (in decayed ani- 

 mal), 28 and 31 ; August 4, 12 (meadow), 14 (meadow), 21, 

 29, 30 and 31 ; September 5. Baraga Co., August 22, Sep- 

 tember I (meadow). 



' ' This species was common under stones in fields and pas- 

 tures. I found them particularly common under the stones 

 scattered over the lumber mill sawdust pile. There were usu- 

 ally one male and one or two females under each suitable stone, 

 but under one large stone I discovered four males and as many 

 females. Their high, shrill chirping was constant, and could 

 be heard at quite a distance from the sawdust pile. I have 

 found the snake Storeria occipitomacidata under the same 

 stone with a pair of these crickets. One day I came upon 

 two males waging war under the edge of a stone. They 

 were facing each other and, with wing covers half raised, one 

 kept up a continuous whirring sound, sometimes rising in 

 volume to a chirp. The other i-esponded with a succession of 

 faint chirps. They continued to edge around each other for 

 several minutes, but I was obliged to leave and was unable to 

 witness the outcome of the struggle. ' ' 



The males in this series have the tegmina, almost without 

 exception, solid blackish ; while the females present all types 

 from a blackish tegmen with a slight brown humeral vitta, to 

 those with the whole organ considerably suffused with dull 

 ochraceous. The latter type of coloration will be seen to 

 approach luduosus, but the smaller size and shorter ovipositor 

 separate it from that form.
