Head biscay green, face yellowish, a very broad postocular bar 

 of mummy brown which is continued on the sides of the body 

 below the pronotum. Antennae with proximal joints marked 

 with blackish, in remaining portions black with light buff, widely 

 spaced annuli, of which the second is much the largest, occupying 

 three joints. Pronotum biscay green, the lateral lobes very broadly 

 margined ventrad with cream color, this showing traces of mars 

 brown along its inner margin. Tegmina serpentine green with 

 countless microscopic flecks of dark vinaceous (the intervals between 

 the very closely packed veinlets), costal margin white, with a 

 slightly narrower internal border of dark vinaceous, sutural margin 

 more broadly black between the brown veins, this occupying all 

 of the anal field. Wings apricot buff, the anterior field suffused 

 with acajou red and the transverse veins of the radiate field strongly 

 defined in that color. Abdomen washed with acajou red dorsad. 

 Ovipositor green, suffused with brown distad. Limbs green and 

 brown, the tibiae with dark dorsal margins, the femora tipped 

 dorsad with black, with a white area immediately preceding and 

 in strong contrast. 



Length of body 27 and 19 (the latter specimen shrunken, the 

 measurements of the type being given first), length of pronotum 

 4.5 and 4.7, caudal width of pronotal disk 4.8 and 4.9, length of 

 tegmen 26.8 and 24, greatest (median) width of tegmen 8.7 and 

 6.9, meso-distal width of tegmen 7 and 5.8, length of cephalic femur 

 9.8 and 9.6, length of caudal femur 17.8 and 16.4, length of ovi- 

 positor 8.2 and 8.1 mm. 



A female paratype, bearing the same data as the type, is before us. 



Scambophyllum sanguineolentum (Westwood)

 pi. XXV, fig. 3. [<?, 9 ; Sumatra.]

This small immature individual is dark brown, beautifully marked 

 with buff and white. There is no question that it represents the 

 genus, but we can not say with certainty the same for the specific 

 determination. One species only, however, has been recorded from 

 Sumatra. 

 Scambophyllum sandakanae new species. Plate XII, figures 2, 3 and 4. 



The unicolorous wings and lateral margins of pronotal disk 

 defined by dark markings are striking features of difference in this 

 insect. In addition, though the emargination of the costal margins 

 of the tegmina is more sudden even than in S. sanguineolentum 

 (Westwood), these organs taper more strongly distad even than in 

 S. albomarginatuni here described, with venation more delicate and 

 different in several important respects.
