SOME UNDESCRIBED RHOPALOCERA FROM SIAM. 177 



8 mall black spots, there being none in area 4, secondly, a series of 

 seven crescentic black marks reaching from vein to vein and nearly 

 touching each other and, thirdly, a heavy black wavy line fusing 

 with "the marginal border at each end. Abdominal area grey. 



Underside, bofh wings. — Pale ochreous, the markings of the 

 upperside represented by brown. A narrow transverse wavy line 

 crosses cell of forewing obliquely to origin of vein 2, thence to inner 

 margin, and is continued interruptedly across hindwing as far as 

 vein la. A very well-defined narrow straight black line starts at 

 origin of vein 7 of forewing and runs uninterruptedly to anal angle 

 of hindwing, is diffusely edged outwardly with brown, more 

 particularly on hindwing, and bordered inwardly, on hindwing only, 

 as far as the irregular transverse fiscal line, with dull mother-of- 

 pearl. The forewing has a small oval apical patch of lilac-grey. 



The veins on upperside are throughout delicately black, those 

 of forewing, and veins 5, 6 and 7 of hindwing being, in addition, 

 edged with golden. 



Length of forewing.-32 mm.

On the upperside the markings of G. ehione much resemble 

 those of C. orissa, but the light cliscal band is curved, not straight as 

 in that species, and the basal dark area is bounded by a well-defined 

 dark line. The markings of the hind-margin of the hindwing and 

 of the underside are however very different, the latter more nearly 

 resembling in arrangement those of C. surya, C. aoris and 

 C. malaya.

d. Most closely resembles the subspecies burmana de Nice- 

 ville, in the absence of brown suffusion of its white markings. With 

 the exception of the longitudinal streak on the forewing, which is 

 distally slightly cloudy, these are entirely pure white. They are 

 however much smaller than in burmana, being approximately the 

 size of those in typical cart ico ides Moore. The underside colouration
