Raffles Museum, Singapore, Two of 

 them had been collected by Mr. C. BO- 

 DEN Kloss in Kuala Lumpur, Federated 

 Malay States, in January & February 1918 

 respectively, and the third, from Selitar, 

 Singapore, was taken by Mr. F. MON- 

 TEIRO, February 13th 1918. The following 

 description refers to the first of these 

 three specimens, from Kuala Lumpur. 



Head free. Epicranium red; eyes, clypeus, 

 labrum and mouth parts generally' black. Antennae 

 setaceous. Pronotum black, with a narrow white 

 border all round; near its centre two white 

 comma-like markings each of which is enclosed 

 in front by a white hook-like line. Tegmina ') 

 black at ihe base, turning greyish-brown towards 

 the tips, with all the veins chalk-white, clearly 

 standing out against the dark back ground. 

 Radial vein with 12 costal veins^he first eight 

 simple, the 9th bifurcated, the 10th trifurcated» 

 the 11th and I2th simple. Ulnar vein sending? 

 branches towards the suturai margin, of which 

 the 4th and 5th are bifurcated, the others 

 simple. Anal area with 5 axillary veins. 



Wings transparent, with the anterior mar- 

 gin infuscated. Mediastinal vein simple, proxim- 



ally fused with the radial vein. Radial vein bifurcated, with 3 or 4 anastomoses 

 between the two branches; outer branch with 4 or 5 costals ; inner branch with 10 to 

 12 costals which may arise singly, or multiramose, i.e. 3 to 5 branches from a common 

 trunk. Costals all incrassated. Median vein simple or bifurcated. Ulnar vein sending 3 

 or 4 branches to the apex only, of which the last branch is bifurcated, the others 

 simple; apex of Ulnar vein bifurcated. Small apical field. First axillary vein 4-ramose- 

 Front femora armed with about 3 strong spines, succeeded distally by a close-set 

 row of minute piliform spines (the proximal portion of the front femora being almost 

 free of spines). 



Total length 12 mm; body 8.5 mm; tegmina 10 mm; pronotum 2.5X3.7 mm.

hi the specimen examined right and left wing differ in their venation. 

 The first 4 costals of the left wing spring from the outer branch of the 

 radial; these are followed by 3 costals arising singly from the inner branch 

 of the radial, then by 5 costals from a common trunk, and finally by 3 

 costals, also from one trunk, hi the right wing we find 5 costals arising 

 from the outer radial, followed by three groups of 4, again 4, & 2 costals 

 respectively, springing in common trimks from the inner radial. More curious 

 is that the median vein of the left wing is simple, that of the right wing 



') Both pronotum and tegmina of the Buitenzorg example are brown. This is possibly 

 merely due to fadicy, unless the specimen should represent a local variety.
