graspers. The head is slidrt, much wider than lonj;\ triangular, vertical, 

 and loosely jointed to the tliorax in such a manner as to be freelj' mov- 

 able ; antennae slender, usually tiliform, rarely half as long as the body ; 

 eyes very large, convex, prominent; ocelli three in number, arranged on 

 a triangular elevation just above the insertion of the antennae ; pro- 

 notum usually several times longer than broad, with the broadest part 

 in front of the middle and above the point of attachment of the long fore 

 coxae ; both inner and outer wings usually present but often shorter than 

 the abdomen in the females ; the abdomen of that sex often much broader 

 than that of the male, and without a visible ovipositor. 



"Both sexes have a pair of short jointed cerci attached to the sides 

 of the supra-anal plate, while the males have also a pair of much shorter 

 styles near the apex of the subgenital plate. They have the fore legs 

 stout and raptorial, the tibiae terminating in a long claw and with the 

 long, slender, five-jointed tarsi, when at rest, bent back into a groove on 

 the under side of the spinous femur; middle and hind pairs of legs long, 

 slender, and fitted for slow motion." 



A single species of this family has been recorded from the Province. 



Litaneutria minor Scudder, 1872. 



Scudder, Samuel H. Rep. U. S. Geol. Surv. Nebraska, p. 251 (1872). 



A specimen of this insect was taken in the Lower Okanagan Valley at 

 Osoyoos in 1920 by Mr. E. Hearle, of the Dominion Entomological Branch. 

 It was found on a Sage-brush (Artemisia tridentata) plant. We are 

 indebted to Mr. Morgan Hebard, of the Academy of Natural Sciences of 

 Philadelphia, for the determination of this specimen. Mr. Hebard says 

 "The Mantid is a specimen of the very common and widely distributed 

 Litaneutria minor Scudder. The record is, however, of the greatest 

 interest, as you note, the first native species of Mantidae, from Canada. 

 The species is found generally over the arid and semi-arid regions of the 

 Western United States and adjacent Mexico."

Family 4. PHASMIDAE 

 (The Leaf and Stick-Insects) 

 No representatives of this family have as yet been recorded from 

 British Columbia. 



Family 5. ACEIDIDAE 

 (The Short-horned Grasshoppers) 



The family Acrididae includes an immense number of species. The 

 members of this family maj' be defined as: Orthoptera with fore and 

 middle legs of nearly equal size and hind legs longer than middle legs 

 with their femora enlarged ; tarsi of three segments ; the terminal or 

 third segment furnished with two strong claws, an aroliiini or pad is 

 found between the claws of the tarsi (except in the Acrydiinae). Teg-
