 8. Centrotypus brunneus sp. nov. (Figs. 1 and 2). 



A large robust species, entirely brown ; roughly punctate ; 

 sparingly pubescent; suprahumeral horns very sharp, extending 

 outward and curving upward ; posterior process long, slender, 

 sharply carinate above and extending to a point about midway be- 

 tween internal angle and tip of tegmen; tegmina entirely brown, 

 wrinkled, sparsely pilose, coarsely punctate at base ; legs and under- 

 surface of body brown. 



Head subquadrangular, wider than long, entirely and uniform- 

 ly brown, roughly sculptured, coarsely punctate, sparingly pubes- 

 cent with grayish hairs ; base of head convex above, highest above 

 ocelli : eyes very large, very prominent, grayish-brown, extending 

 beyond lateral margins of adjoining pronotum; ocelli very large, 

 grayish-brown, farther from each other than from the eyes and 

 situated somewhat above a line passing through centres of eyes; 

 clypeus heavy, brown, roughly sculptured, punctate, sparsely pubes- 

 cent with grayish hairs twice as long as wide, extending for more 

 than two-thirds its length below the inferior margins of the 

 genae, the tip subtruncate and almost as wide as the base, lateral 

 margins slightly expanded just below inferior Hue of head. 



Pronotum entirely brown, roughly punctate, sparingly pubes- 

 cent with grayish hairs; metopidium nearly perpendicular, very 

 slightly convex above, three irregular smooth callosities on each 

 side above lateral margins of head; humeral angles large, pro- 

 minent, auriculate; suprahumeral horns sharp, curved, projecting 

 at first nearly horizontally as seen from the front and then dis- 

 tinctly curving upward, about as long as the distance between their 

 bases, flattened dorso-ventrally, irregularly rugose above, bicarinate 

 below, tips slightly bent backwards, distinct depression on each 

 side between base of horn and base of humeral angle; median 

 carina percurrent, sharply ridged behind suprahumeral horns; 

 dorsum sloping, only slightly gibbous before base of posterior pro- 

 cess; scutellum distinctly exposed on each side, brown; posterior 

 process long, slender, nearly straight, very slightly sinuate above, 

 somewhat decurved at tip, dorsal carina high and sharp, <a strong 

 lateral carina on each side at base extending from behind base of 

 suprahumeral horn to lateral margin of process about one-third 

 the distance from the tip, tip acuminate, extending beyond the tip 

 of the abdomen and to a point about half-way between the internal 

 angle and the apex of the tegmen. 



Tegmina entirely browm, wrinkled, semi-translucent; veins 

 more or less curved in central area; basal half coarsely punctured 

 and sparingly pilose with grayish hairs ; five apical and three dis- 

 coidal areas. Hind wings hyaline, veins blackish, four apical areas.
