AcRYDii — Latreille. 



Chloealtis, Harris. 



C. coNSPERSA, Harris, Report Ins. Mass., 3d Ed. 184. 



C. abortiva, " " " " 



This species was obtained in abundance on the 4th July, at Dog's 

 Head, eastern shore of Lake Winnipeg, leaping about actively 

 when disturbed, and apparently living exclusively among the 

 lichens which bordered the patches of rocks. 



Stenobothrus, Fischer Fr. 



S. CURTIPENNIS. 



Chloealtis curtipennis^ Harr., Report Ins. Mass. 3rd ed. 184 

 pi. 3, fig. 1. 



This species, which is one of the commonest N. England forms, 

 was found abundantly at the Red River settlements. The figure 

 in Harris' Report is quite inaccurate. 



Aroyptera, Serville. 



A. GRACILIS, nov. sp. 



Vertex of the head rather broad, swollen at front border of the 

 eye, the edge raised to a ridge, with a medial ridge extending 

 over the whole top of the head ; foveolae long and narrow, trian- 

 gular, rather deep; pronotum rugose ; wing covers short and broad, 

 costal border somewhat swollen near the base, internal border full. 



Dark brown; a narrow curved dark line extends from the 

 upper border of the eye to the lateral carina3 of the pronotum, 

 and is the inner limit of a rather broad brownish-yellow band, 

 which extends from the hind border of the eye to the lateral 

 carinse, whence it continues backwards crossing the carinsB ; 

 below this upon the upper border of the sides extends a 

 narrow black'band from the eye to the hind edge of pronotum ; 

 the medial carina is black ; wing-covers uniform dusky brown, 

 except the internal border, which is yellowish brown ; wings 

 dusky, with a yellowish tinge on the internal half; hind femora 

 reddish, black at apex ; hind tibiae yellow with black spines, 

 with the base and apex black, and a dark annulation at the upper 

 limit of the spines. 



Length of body -85 in. ; of wing-covers '78 in. ; breadth of wing- 

 covers in middle -22 in.; length of hind femora -52 in. 



This species seemed to be rather abundant at Red River. I 

 know it elsewhere only by a single specimen from Maine. 



Pezotettix, Burmeister. 



P. BOREALIS, nov. Sp. 



Vertex of the head with a broad longitudinal furrow in advance
