TYpe : female. 



Locality: Sandakan, Borneo. 



Type (Baker's duplicate No. 9524) in author's collection. 

 In the type specimen the outer discoid al cell on one tegmen is 

 subdivided but the other tegmen is normal. 



50. Parayasa maculipennis sp. nov. (Fig. 15). 



Shining black; tegmina with three Ion": and one very short 

 white fasciae and four large apical cells; posterior process strongly 

 sinuate and not nearly reaching to internal angles of tegmina : 

 ocelli very much farther from each other than from the eyes ; under- 

 surface of body black; legs dark brown. 



Head very convex, about as long as broad, black, shining, punc- 

 tate, very sparingly pubescent at lateral basal angles; eyes large, 

 prominent, yellowish-white with brown markings near inner mar- 

 gins; ocelli small but very prominent, yellowish, glassy, glistening, 

 very much farther from each other than from the eyes and situated 

 near the lateral margins of the head somewhat above a line drawn 

 through centres of eyes ; inferior margins of genae short and nearlv 

 straight: clypens much denexed. convex, black, shining, finely 

 punctate, extending for two-thirds its length below the inferior 

 margins of the genae, tip rounded, somewhat swollen, sparingly 

 pubescent. 



Pronotum entirely black, finely punctate, shining, very faintly 

 pubescent; metopidium sloping, broader than high, slightly de- 

 pressed above eyes, black, shining, finely punctate: humeral angles 

 very broad, prominent, auriculate, blunt; dorsum strongly sinuate, 

 a depression just behind humeral angles and another in centre of 

 posterior process, between these depressions much swollen; median 

 dorsal carina very faintly percurrent: posterior process short, heavy, 

 blunt, a swollen elevation at base and at tip, faintly carinate along 

 median dorsal line, tip rounded and not nearly reaching internal 

 angles of tegmina ; scutellum not exposed when tegmina are closed. 



Tegmina black, opaque, shining; base coriaceous and punctate; 

 veins noticeably pilose ; four shining white linear fasciae extend- 

 ing across the tegmen at various angles as follows : one very short 

 white line extending from centre of margin of posterior process 

 across the clavus caudo-ventrad to the fold of the corium; another 

 white line extending entirely across the tegmen diagonally from 

 the tip of the posterior process cephalo-ventrad to the costal margin 

 near the edge of the basal punctuation; another wider white line 

 beginning on the costal margin about two-thirds of the distance 

 from the base and extending cephalo-dorsad about half-way across 

 the tegmen ; another broad white fascia extending across the tip of 

 the tegmen just inside the apical veins. The tegmen has four large 

 apical cells and two discoidal.
