portion of section beyond this tooth; cerci straight and scarcely- 

 taper to that point, thence evenly recurved and show weak con- 

 vergence of the lateral margins to the bluntly bidentate apices. 

 Subgenital plate very small, with a median transverse ridge, beyond 

 this with lateral margins straight and parallel to the slightly de- 

 curved styles, each of which is nearly four times as long as its basal 

 width, separated by a distance slightly greater than the length 

 of one of these, the subgenital plate briefly produced between 

 these and strongly transverse, trapezoidal. Cephalic coxae armed. 

 Genicular lobes of all femora bluntly rounded. Cephalic tibiae 

 very slender, except at the auditory foramina, which portion is 

 decidedly swollen, ventral margins armed with four pairs and one 

 external (or rarely five pairs) of elongate spines and with a distal 

 pair of minute spines. These spines are unusually long for the 

 genus, the longest slightly over four times the width of the tibia 

 at that point. Median tibiae ventrad with five pairs of shorter 

 spines and with a minute pair of distal spines; thickened in proximal 

 two-thirds, decidedly more slender in distal third. Caudal tibiae 

 armed as described for Alloteratura on page 250. 



Allotype: 9 ; Island of Penang, British Straits Settlements. 

 (From C. F. Baker.) [Hebard Collection.] 



Agrees closely with male, differing as follows. Size very slightly 

 larger. Production of pronotum decidedly shorter, the metazona 

 two-thirds as long as the prozona; lateral lobes with concavity of 

 caudal margin opposite thoracic foramen less than at humeral sinus. 

 Supra-anal plate small, subtriangular with apex very broadly round- 

 ed, impressed meso-proximad. Cerci cylindrical, widest meso-proxi- 

 mad, thence tapering to their acute apices, slightly incurved and 

 hardly three times as long as greatest width. Ovipositor elongate, 

 swollen proximad, distal portion curved very weakly dorsad with 

 margins unarmed; dorsal valves acute at apex, ventral valves 

 with a very faint concavity of ventral margin just before apex, 

 with apex itself rounded and decurved. Subgenital plate of the 

 same type as in lita, differing in being supplied with stiff hairs, 

 while the produced, triangular, median portion is much larger, 

 leaving only brief convex lateral portions, the produced portion 

 only half as long as its basal width, with apex sharply rounded. 



General coloration pale yellowish brown, probably immaculate 

 light green in life. The genicular lobes of the caudal femora are 

 tipped with blackish brown, this apparently of specific diagnostic 

 importance. The intersection of the antennal segments are weakly 

 embrowned to different degrees. The tegmina show the sutural 

 margin faintly tinged with brown, as are the areolae toward that 

 margin. 



The measurements of the type are given first for the male sex, 

 those of the allotype first for the female sex. Length of body cf 11 

 and 9 (greatly shrivelled), 9 11.5 and 11.3; length of pronotum 

 cT 4.1 and 3.9, 9 3.6 and 3.4; greatest total width of pronotum
