262 Mr. A. G. Butler's descriptions, §-c. 



This species appears to be not uncommon in Borneo, 

 altliougli until this year I never saw it. It is very 

 similar in pattern to A, assamensis, but differs entirely in 

 colour. 



Angonyx vigens, n. sp. 



Same size and form as the preceding; primaries above 

 pale greyish-brown, tinted with rose-coloiu- and clouded 

 with green ; a bright green patch from base to second 

 third of internal area, a whitish nebula about the centre 

 of the disc with similar (but less vivid) oblique line run- 

 ning to apex, to that of the preceding species ; a subpyri- 

 form inverted black spot at the end of the cell, followed 

 immediately by a straight transverse black belt, which 

 crosses the wing from costa to inner margin ; two pale- 

 edged recurved dusky lines across the basal area, a pale- 

 edged black spot at base of costa, a crenulated blackish 

 discal line, most distinct at costa and inner margin, a 

 black spot close to external angle ; secondaries nearly as 

 in the preceding species, but more purple in tint, the 

 outer border limited internally by indistinct red spots; 

 body purplish-brown, clouded with green ; the sides of 

 head, thorax and the tegulse dark olivaceous, edged 

 externally with lilacine, green and white : under surface 

 much like the preceding species, altogether redder, the 

 apical fourth of costal border of primaries Avhitish ; ex- 

 ternal border less prominent, less strongly dentated, only 

 bounded internally by a pale ochraceous angulated spot 

 near the inner margin ; disc distinctly red and limited 

 internally by a black line elbowed upon the costa ; the 

 suba])ical costal oblique spot greyish, outlined and inter- 

 sected by black lines, a whitish wavy streak across the 

 outer border ; secondaries rosy-grey, with the outer border 

 whitish internally, indications of three parallel blackish 

 lines, between which the veins are white, across the disc ; 

 body rosy-grey, with markings as in A. borneensis : ex- 

 panse of wings 2 inches. 



Ilab. — Philippines. 



This beautiful species probably replaces A. borneensis 

 in the Philippines.
