lations very small, a brown triangular mark over inner apical portion, 

 the veins in this portion being darker, cubitus, media and radia each 

 with a small brown spot before cross-veins. 



Length 3 mm. ; tegmen 3 mm. (with apex of tegmen de- 

 flexed.)^ 



Hab. Pontianak, Borneo, on sugar-cane. This species is 

 very near gracilis, under which name it is likely that Matsu- 

 mura has more than one species, it also comes near to hama- 

 dryas. 



(2.) T. festiva (Distant) 



Plate 6, Figs. 9, 9a 



There are specimens in our collection from Borneo and Java 

 that agree with Distant's and Matsumura's descriptions, but the 

 head is just double the length of the pronotum. I figure the 

 male genitalia. 



(3) T. atrata (Distant). 



Plate 6, Figs. 10, 10a. 



There are two specimens from Macao, China, Avhich appear 

 to be this species; the male agrees with Distant's description, 

 but the female is more yellowish-brown than green. I figure 

 the male genitalia which differs from festiva by having nar- 

 rower stylos, and the prong from the base is more slender, also 

 the outline of the pygophor is different. The vertex is slightly 

 less than twice the length of pronotum. (1.9 to 1.) 



(4) T. saccharivorella Matsumura. 

 One specimen from Macao, China. 



(5) T. amhoinensis sp. nov. ( 5 ? ) 



Plate 6, fig. 12. 



Vertex one and a half times the length of pronotum (1.5 to 1). 

 Brownish yellow, darker dorsally; keels on vertex, pronotum and 

 scutellum finely bordered with black; antenna with a black ring on 

 basal segment and two on second segment, the one near apex faint; 

 face yellowish, lateral keels finely streaked with black; genae beneath 

 eyes and the clypeus brown; legs yellowish with black spines; ab- 

 domen yellow with brown segmental markings. Tegmina approaching 

 hnt n ill pain ix; brown with transparent, viteline patches, one from base 

 along inner border of clavus, from end of clavus across to costa, and 

 a small one in the apical subcostal and radial cells, veins darker,
