weakly defined. Ultimate tergite produced, truncate distad, 

 lateral portions convex, mesad showing an angulate concavity 

 which is narrowest distad. Supra-anal plate beneath, shield- 

 shaped. Cerci slender, simple, cylindrical, tapering and weakly 

 curved inward to the apex, which is armed with a very minute 

 tooth. Subgenital plate moderately produced, tri-carinate, with 

 lateral carinae rounded; distad bluntly V-emarginate, the lateral 

 portions truncate and surmounted by small, simple styles, slightly 

 longer than the depth of the emargination and three times as long 

 as wide. 



General coloration rich oil green. Lateral margins of pronotum 

 and stridulating field of tegmen yellowish, beyond the sutural 

 margin of the tegmina is blackish or has the minute intervals 

 between the veinlets blackish, this continued to the apex. Proxi- 

 mad on the tegmina, particularly in the marginal field, moderately 

 large suffused flecks of darker green or purple drab are indicated. 

 Caudal margin of pronotum immaculate in male, faintly margined 

 with black in Labuan female, narrowly but distinctly margined 

 with black in Sandakan female. 



Length of body d* 36, 9 34 and 35.8; length of pronotum d" 8.7, 



9 8.9 and 9.4; caudal width of pronotum cf 7, 9 7.2 and 7.7; 



length of tegmen cf 53.8, 9 49.2 and 52.7; greatest width of tegmen 



c? 18, 9 17.8 and 18.2; length of caudal femur <? 22.3, 9 19.8 



and 21.2; length of ovipositor 7 and 7.7 mm. 



This handsome species is known from the described pair and a 

 paratypic female from Sandakan, British North Borneo, from 

 C. F. Baker.

This insect is clearly a higher development from a type similar 

 to that of Sympaestria. Brunner separated these species very 

 widely, due to the presence in Dysmorpha of apert auditory fora- 

 mina on both faces of the cephalic tibiae. Though representing a 

 Group, the Dysmorphae, we place it immediately after the genus 

 Sy?npae stria. 



The female before us is found to resemble the type closely. The 

 ovipositor is broad, upcurved, with apex rounded, suggesting the 

 type developed in Eulophophyllum. 



The richness and beauty of the coloration in this insect is very 

 striking. The tegmina are shell-like, glossy, with stridulating 

 field blackish brown, except for a few small areas of javel green. 



33 A Sumatran male of this species has subsequently been fully described by 

 Griffini (Wiener Ent. Zeit, XXVIII, p. 105, {1909).)
