Oxyambulyx cyclasticta, Joicev & Kaye, 1917, p. 308 (Burma) ; 

 id., 1924, pi. xi, fig. 6 ; Seitz, 1928, p. 535. 



Imago. — Fore wing reddish- ochre. A small dark spot at 

 base ; a squarish olive -coloured spot on costa, and below 

 it beyond cell a large circular olive spot with a pale ring ; 

 a pair of elbowed transverse lines slightly wider apart at costa 

 than at inner margin, the first passing through cell and almost 

 touching the discocellular, the second well beyond cell. 

 Between veins M 1 and M 2 , close to the outer transverse line, is 

 a dull-coloured rather inconspicuous round spot. A dark 

 marginal shade ending at apex and before tornus in a point. 

 Between this shade and outer transverse line ground-colour 

 darker, with faint indication of two crenulate transverse 

 lines and a rudimentary third line before apex. Hind wing 

 ochreous, with a straight oblique line just beyond cell and 

 a greatly curved and indented line between this and the outer 

 margin. Outer margin crenulate, with white cilia between the 

 veins. Thorax reddish-ochreous with dark reddish-olive sides. 

 Underside : fore wing with dark spot between veins M 1 

 andM 2 conspicuous, ground-colour reddish-fawn. Outer area, 

 especially in apical portion, heavily marked with reddish 

 freckling. Hind wing reddish-ochreous, with first line well 

 defined, second curved line merged in the general reddish 

 freckling towards costa. Expanse 108 mm.

Genotype : phalaris (Cram.). 



Imago. — Upperside of fore wing and body some shade of 

 cinnamon-brown to red-brown, and that of the hind wing 

 varies from cinnamon-yellow or buff to red-brown ; underside 

 similar but paler ; usually a greyish, median, costal patch 

 and a small subapical patch which is darker than the surrounding 

 area ; hind tibiae white above in some cases, and in others 

 both hind and mid- tibiae white above. The moths are all large, 

 the ($$ up to 135 mm. and the $9 U P to 150 mm. expanse. 



" o 2. Tongue rather stout ; but not reaching beyond the 

 hind coxa. Pilifer with bristles. Palpus incrassate distally, 

 rather prominent in $, the seriated cilia short in and near 

 the mesial line, segments circular in trans-section in §, with 

 very slightly prolonged basal and apical cilia ; the end- 

 segment is short. Abdomen with many weak spines dorsally 

 underneath the ordinary scaling, apical spines of segments 

 numerous. Tibiae spinose ; spurs unequal, two pairs to hind 

 tibiae ; pulvillus and paronychium present, the latter with
