Family IV : Locustid^. 

 This number contains a few powerful species, some of curious 

 appearance, confined so far as is known, to the Pal^arctic region, and 

 carnivorous in habits. They are characterised by the closed or cleft- 

 shaped tympanum of the anterior tibiae, which are sulcate at the sides, 

 and have on the outer edge of the upperside three distinct spines ; the 

 hind tibiae have terminal spines on both sides of the upperside, and 

 four terminal spines beneath.
