NEW RECORDS & SPECIES OF MALAYAN MEMBRACIDAE. 217 



both sides, very densely pubescent with yellowish or golden hairs ; 

 posterior process short, nearly straight, strongly tricarinate with a 

 median ridge above and a lateral ridge on each side just above 

 lateral margin, extreme tip very sharp, black, extending just to 

 internal angle of tegmen. 



Tegmina smoky -hyaline tinged with ferruginous ; somewhat 

 wrinkled, especially on the rather broad apical margin; base black, 

 coriaceous, coarsely punctate, sparingly pubescent; costal margin 

 of apex very narrowly and faintly marked with light brown ; veins 

 in central area of tegmina very heavy, upraised and black; a rather 

 narrow transverse area just following coriaceous base lighter than 

 other parts of tegmen; five apical and two discoidal cells. 



Fndersurface of body very dark brown, rather closely pubes- 

 cent with silvery hairs ; coxae, trochanters and femora dark brown ; 

 tibiae and tarsi ferruginous; tibiae minutely spined and pilose; 

 hind trochanters strongly armed with teeth on the inner surface. 



Length 5.7 mm. ; width between extremities of humeral angles 

 '2.8 mm. 



Type : female. 



Locality: Sandakan, Borneo. 



Type (Baker's duplicate Xo. 9512) in author's collection; 

 allotype and paratype in Professor Baker's collection. 



One tegmen of the type specimen shows three discoidal cells 

 instead of two, a variation not unusual in the tegmina of the sub- 

 family Centrotinae and an evidence of the fact that the number 

 of discoidal cells is not a reliable character for specific diagnosis. 



30. Centrotoscelus pseudocornis sp. nov. (Figs. 13 and 14). 



Small, black, with slight protuberances which resemble horns 

 above the 'mineral angles ; posterior process just reaching internal 

 angles of tegmina; tegmina smoky-hyaline except base which is 

 black and punctate; tibiae and tarsi ferruginous. 



Head wider than long, black, roughly sculptured, densely 

 pubescent with silvery hairs; base strongly sinuate; eyes large, 

 prominent, brown ; ocelli small, brown, glassy somewhat farther 

 from each other than from the eyes and situated slightly above 

 a line drawn through centres of eyes ; inferior margins of genae 

 sloping, weakly sinuate, flanged; antennae very fine but visible; 

 clypeus about twice as long as wide, black, densely pubescent, pro- 

 jecting for half its length below inferior margins of genae, tip 

 rounded and pilose. 



Pronotum black, finely punctate, closely pubescent with silvery 

 hairs ; metopidium convex, broader than high, a black callosity over 

 the internal angle of each eye, barely carinate on inferior half; 

 humeral angles large, prominent, triangular, blunt ; a strong ridge 

 suggesting an undeveloped horn above each humeral angle; median 

 carina strong on posterior half of pronotum, weak over humeral 

 angles and almost obsolete on metopidium : scntellum plainly ex- 

 it. A. Roc, No. 82, 1920
