Length of body 24, length of pronotum 6.2, caudal width of 

 pronotum 3.4, depth of pronotal lateral lobe 5, width of pronotal 

 lateral lobe 4.2, length of tegmen 35.3, greatest width of tegmen

The type is unique. 



Stictophaula quadridens new species. Plate XIII, figure 13. 



Nearest the Javan S. spinoso-laminata (Brunner), the male of 

 this insect may be quickly distinguished by the subgenital plate, 

 which is produced distad in two slenderly acute-conical projections, 

 between the bases of which are two sharp, straight teeth, one-third 

 as long. 



Un.ike that species and S. bakeri here described, the present 

 insect has the pronotum and limbs immaculate. The tegmina 

 have the stridulating field more extensively suffused with blackish 

 brown than in bakeri, but with brown areolae along the sutural 

 margin much less conspicuous. 



The tegminal venation is much as in bakeri, differing as described 

 below. 



Type: cf 1 ; Singapore, British Straits Settlements. (From C. F. 

 Baker.) [Hebard Collection, Type no. 854.] 



Agrees with the description of bakeri in all details except the 

 following. Tegmina with median vein branching mesad, the 

 cross-veinlets to the median vein more distinct and not gathering 

 knots of veinlets near their bases. Subgenital plate narrowing 

 proximad, mesad with a weak medio-longitudinal carina, distal 

 portion briefly produced, terminating on each side in a slenderly 

 acute-conical spike, each of these slightly longer than the distance 

 between their bases, that interval supplied with two sharp, straight 

 teeth of one- third the length, the narrowly U-shaped interval 

 between these slightly deeper than the similar intervals between 

 them and the lateral projections. Ventral femoral margins armed 

 with minute spines as follows. Cephalic internal 5 and 7, cephalic 

 external 0, median internal 0, median external 9 and 10, caudal 

 internal 4 and 4, caudal external 9 and 9. 



Tegmina translucent light grape green, body and limbs im- 

 maculate (discolored, in life probably the same color). Tegmina 

 in areolae on each side of ulnar and principal branch of median 

 vein with a few of the minute intervals between the veinlets mesad 

 black; stridulating field blackish brown in proximal half, sutural 

 margin beyond stridulating field very narrowly and weakly suffused, 

 with veins brown and very minute intervals between veinlets 

 blackish, to apex. 



Length of body 21 Cshrivelled), length of pronotum 6.2, caudal 

 width of pronotum 3.7, depth of pronotal lateral lobe 4.9, width
