Subfamily II. TRYXALINAE 

 (The Oblique-faced Locusts) 



In the Tryxalinae the vertex of tlie head i.s nearly horizontal, the face 

 quiU' oblique, generally forming an acute angle at the union with the 

 vertex. Lateral foveolae are usually well developed, although some- 

 times absent. The eyes are usually longer than that portion of the genae 

 below their orbits. The antennae are variable, being accuminate, de- 

 pressed, or rarely clavate, and situated between or below the middle of 

 the eyes. The pronotum has the front and rear margins of the disk 

 nearly equal in width ; all the carinae are usually distinct, the median 

 carina cut by one sulcus and not raised in the form of a crest. The 

 tegmina and wings are often short and rudimentary, but sometimes fully 

 developed in members of the same species. In our British Columbia 

 species the inner wing is always transparent, without bright colours or 

 a black band.

 p. 454 (1862). 



A few specimens of this species have been taken in the Okaiuigau 

 Valley. It is a sluggish insect and apparently by no means common in 

 British Columbia. It has been found in dry, rough pastures and in rank 

 growtli of Bunch-grass.

A common insect on the Buneli-grass slopes of the Eraser and Chil- 

 eotin Valleys in the Chileotin district. It probably occurs throughout 

 the central Dry Belt of the Province wherever \varm, dry, grass cov- 

 ered slopes are found. Mr. Rehn informs me that "Tlu; situation in the
