288 Scudder's List of Orthoptera, 



Locusta latipenniSy Harr. Report, Ins. Mass., 3rd ed. 178. 



I found this species at Pt. Wigwam, Lake Winnipeg, on 1st Au- 

 gust, abundant at mid-day flying about on the sandy spots, like the 

 preceding species it makes a crackling noise with every successive 

 flutter of its wings. I have seen it elsewhere only from N. England. 



Uhler, (Harr. Report Ins. Mass., 3rd ed., 178,) considers this 

 to be identical with the previous species, in which opinion I can 

 hardly concur — it differs from (E. eequalis in the following par- 

 ticulars : in (E. cequalis the black band across the middle of the 

 wings is broad, its outer edge as well as the inner distinct, the 

 outer border at first straight, then well rounded, curving inwards 

 where it approaches the outer border ; beyond the band the wing 

 is pellucid with black veins not cloudy, and at the tip there is 

 either a dusky patch, or irregularly clustered square blackish 

 spots ; in CE. verruculata the inner border of the band is more 

 wavy and is illy defined ; the outer border is straight, and where 

 it approaches the outer border of the wing is turned slightly out- 

 wards instead of inwards, and is frequently very indistinct, being 

 merged into the more or less dusky space beyond it, which in- 

 creases in cloudiness to the tip, where it is as* dark as the band ; 

 the band itself is quite narrow in the middle, so that it might be 

 said to be made up of two triangular patches which meet and 

 merge in the middle ; the broadest band I have seen in CE. ver- 

 ruculata is not more than half the width of the narrowest I have 

 observed in (E. cequalis ; in (E. cequalis the hind tibise are either 

 wholly coral-red, or have a pale yellowish annulation at the base ; 

 in (E. verruculata the tibise have the base and apex black, with 

 the middle half yellowish, with generally a dusky annulation in 

 the middle.

Tetrix ornala, Harris, Report Ins. Mass., 3rd ed. 186. 



(Not Acrydium ornatum^ Say, Am. Ent. I. PL V.) 



I have not seen this species from British America, but only 

 from northern Minnesota, on the Red River trail, and from N. 

 England, but mention it here because of its having been first de- 

 scribed by Kirby. It is not the species described by Say under 

 the name of ornatum, although it is closely allied to it — it differs 

 from ornatum in the longer extension of the pronotum backward, 

 its greater size, and in the prominence of the vertex, which is 

 angulated in front — it varies much in coloration.
