3. Otinotus pilosus, sp. nov. (Figs. 5 and 6). 



Large, brown, very densely pilose, suprahumeral horns short, heavy, 

 blunt, extending outward and upward and no longer than the distance between 

 their bases; posterior process long, slender, sinuate, impinging on tegmina and 

 extending to a point about half-way between internal angles and apices of teg- 

 mina; tegmina hyaline, wrinkled, base narrowly brown; legs and under surface 

 of body uniformly brown. 



Head twice as wide as long, subquadrate, dark brown, finely punctate and 

 densely pubescent; base sinuately convex; eyes large, prominent, brown; ocelli 

 large, prominent, glassy, transparent, considerably nearer to each other than 

 to the eyes, and situated about on a line drawn through centres of eyes; inferior 

 margins of genae rounded; clypeus nearly three times as long as wide, extending 

 for three fourths its length below inferior margins of the genae, margin adjoining 

 genae angulate, tip broadly rounded. 



Pronotum dark brown, finely punctate, densely pilose with yellowish hairs; 

 metopidium about as broad as high, nearly perpendicular above the head, 

 slightly convex; median carina distinctly percurrent; humeral angles very large, 

 prominent, triangular, blunt, extending almost as far lateral as the suprahumeral 

 horns above them; suprahumeral horns short, heavy, blunt, somicwhat com- 

 pressed dorso-ventrally, strongly tricarinate, extending outward and slightly 

 upward, tips as seen from above roughly truncate; scutellum well exposed on 

 each side, apex yellow, smooth and bidentate, base ferruginous, punctate and 

 densely pilose; posterior process long, slender, sinuate, tricarinate, impinging 

 on tegmina, base not elevated above scutellum, tip acuminate, decurved and 

 black, extending to a point about half-way between internal angle and apex of 

 tegmen but not reaching extremity of abdomen.

 tip pointed; five apical cells. Hind wings with four apical cells. 



Legs and under surface of body uniformly dark ferrguinous brown; sides of

This species is apparently close to O. nigroriifiis Distant, but differs in- 

 colour, in the markings of the tegmina and in the structure of the base of the 

 posterior process. 



4. Otinotus arcuatus, sp. nov. (Figs. 7 and 8). 



Large, robust, ferruginous- brown; suprahumeral horns short, pyramidal, 

 sharply angular, extending outward and upward and about as long as the dis- 

 tance between their bases; posterior process long, heavy, strongly arcuate, the
