Type: 9 ; Labuan, British North Borneo. [Hebard Collection, 

 Type no. 802.] 



The following features are noteworthy, in addition to those given 

 in the generic diagnosis. 



Antennae, beyond first two joints, exceedingly slender. Pro- 

 notal disk with cephalic margin weakly concave and caudal margin 

 broadly convex, lateral margins straight and moderately divergent 

 caudad. Ultimate tergite with a small, transverse, rectangular 

 impressed area above the median portion of the supra-anal plate; 

 the latter broader than long, simple, triangular. Lateral surfaces 

 of ovipositor showing very faint, delicate, transverse striation in 

 distal portions. Subgenital plate with lateral portion reflexed, 

 roughly triangular, the weakly concave lateral margins converging 

 to the rather broadly convex apex. Ventral femoral margins 

 specialized as indicated and armed with the following spines. 

 Cephalic internal (lamellate) 6 and 6, cephalic external and 1, 

 median internal 0, median external (lamellate) 6 and 7, caudal 

 internal 3, caudal external 6. 



General coloration ochraceous buff, the following portions baryta 

 yellow; a vertical subocular line, a very faint postocular line, the 

 broad lateral margins of the pronotal disk, the transverse veins of 

 the tegmina and a broad stripe including the ulnar vein but evenly 

 continued an even distance from the median vein to the tegminal 

 apex. Interval between ulnar stripe and median vein of tegmen 

 greenish, the surfaces adjacent to the transverse veins showing a 

 faint greenish tinge. Antennae of general coloration with very 

 widely separated, rather broad annuli, which in proximal half 

 are whitish and in distal half very dark brown. 



Length of body 26, length of pronotum 5.9, cephalic width of 

 pronotal disk 3.8, caudal width of pronotal disk 5.2, depth of 

 pronotal lateral lobe 5, width of pronotal lateral lobe 4.7, length 

 of tegmen 32.8, greatest width of tegmen 19, length of cephalic 

 femur 7.2, length of caudal femur 20.8, length of ovipositor 18, 

 greatest (meso-distal) width of ovipositor 3.8 mm. 



The type of this extraordinary and leaf-like katydid is unique. 



Sympaestria lampra new species. Plate XIV, figures 5 and 6. 



This handsome species appears to resemble closely Haan's 

 nitidifolia* 2 in general appearance and tegminal venation, differing 

 in having the auditory foramina of the cephalic femora conchate 

 internally, apert externally. 



32 Karny has recently shown that Dohrn was in error in supposing nitidifolia 

 assignable to Sympaestria and in considering the Brazilian Slibara cornea Brunner 

 a synonym of that species. The differences between those species are there dis- 

 cussed, the decision being that nitidifolia is a species of Stibara or a member of a 

 genus more nearly related to that entity than to any known Asiatic genus (Zool. 

 Mededeel. Rijks Mus. Nat. Hist. Leiden, V, p. WO, (1920).).
