224 THE CANADIAN ENTOMOLOGIST 



base slightly raised above the scutellum, tip sharp and extending to a point 

 about midway between internal angles and tips of tegmina; tegmina sordid 

 hyaline, wrinkled, base brown and punctate; legs and under surface of body 

 ferruginous- brown. 



Head twice as broad as long, bright reddish brown mottled with black, 

 roughly sculptured, sparingly punctate, sparsely pubescent with silvery hairs; 

 base regularly rounded; eyes large prominent, dark brown; ocelli large, reddish, 

 somewhat protruded, conspicuous, much nearer to each other than to the eyes 

 and situated about on a line drawn through centres of eyes; inferior margins of 

 gense nearly straight, sloping downward; clypeus nearly three times as long as 

 wide, lobed at angles of genae, extending for three- fourths its length below margins 

 of gense, tip swollen and subtruncate. 



Pronotum reddish brown, finely and closely punctate, sparingly pubescent 

 with whitish hairs; metopidium broader than high, swollen in centre, perpen- 

 dicular above the head, a large irregular callosity above internal angle of each 

 eye; median carina strongly percurrent; humeral angles large, prominent, 

 triangular, blunt; suprahumeral horns short, straight, heavy, strongly tri- 

 carinate, acute, extending outward and upward, about as long as the distance 

 between their bases; scutellum broadly exposed on each side, brown, punctate, 

 pubescent, gradually narrowed to apex which is smooth, white and bidentate; 

 posterior process long, heavy, strongly arcuate, tricarinate, the base slightly 

 upraised above scutellum, the tip acuminate and extending to a point about 

 midway between internal angles and apices of tegmina, but not nearly reaching 

 extremity of abdomen. 



Tegmina hyaline, wrinkled; base brown, coriaceous and punctate; veins 

 prominent and brown; no maculations; five apical cells. Hind wings with four 

 apical cells. 



Legs and under surface of body uniformly ferruginous- brown; sides of 

 thorax densely white pubescent. 



Length including tegmina 8 mm.; width between tips of suprahumeral 

 horns 5.8 mm. 



Type. — Female. 



Locality.- — -Pretoria, South Africa. 



Described from two females collected by Mr. David Gunn on January 

 11, 1915. Type and paratype in author's collection. 



The South African species of the genus Otinotus bear a strong superficial 

 resemblance to the old genus Centrotus (Fabr.), but may be at once separated 

 from the genus by the difference in the number of apical cells of the hind wings.
