they got their full colour, and therefore the streak on the 

 basal joints of antennae has been absent just as in the 

 two specimens before me. Below I give a description of 

 the species. 



Head yellowish green, somewhat flattened on the vertex. 

 The third and fourth of the maxillary palpi more or less 

 blackish ; the fifth quite black with exception of the pale 

 tip. The terminal joint of labial palpi with a broad, dark 

 band. Below the basal joint of antennae a laying y-shaped, 

 reddish brown marking; below the eyes and along the 

 genae an oblique and sometimes abrupted streak, reddish 

 brown or blackish brown coloured. Antennae at least as 

 long as the wings, yellowish at the base and becoming 

 blackish brown towards the apex. Tlie basal joint stout ; 

 the second joint globular; both joints with a narrow, red- 

 dish brown streak along their exterior side. Thorax with a 



yellowish median band and 



greenish side margins. Pro- 

 thorax about twice as broad 

 as long ; a transverse furrow 

 in its apical third ; a median 

 furrow from the transverse 

 furrow to the hind margin. 

 Legs greenish yellow ; the 

 claws brownish and with a

with greenish longitudinal 

 nervures. Sometimes a few of the basal cross veins in the 

 costal area are blackish brown at their ends. The two first 

 cross veins between the radial sector and media, the two 

 basal ones between media and cubitus, and the two between 

 the cubital branches sometimes blackish brown. All the 

 other cross veins greenish. Series of gradate veins parallel. 

 4-8/6-8 in forewing, 3-6/5-7 in hindwing. 



Length of forewing 12 — 14mm; hindwing 11 — 12 mm. 



2 specimens from Batavia, June 1909 and Oct. 1908 

 (freshly emerged); 2 specimens from Nongkodjadar, Jan.
