NEW AND LITTLE KNOWN BUTTERFLI1 209 



median interspace; a much larger portion at the base of the first 

 dian interspace ; an elongated portion filling the base of the 

 submedian interspace, but, opposite the point where the second median 

 nervule arises, the blue patch is suddenly deflected downwards 

 and occupies the posterior half of the interspace, instead of as before 

 being bounded anteriorly by the first median nervule ; the fourth 

 portion occupying the whole of the basal three-fourths of the inter- 

 nal interspace, but not reaching as near to the outer margin as the 

 portion anterior to it does. Hindwing with the blue patch wedge- 

 shaped or triangular, the apex at the base of the wing, its base 

 bounded by the outer margin, which it does not quite reach, thus 

 leaving the costal and abdominal margins broadly and the outer 

 margin narrowly black ; the median nervules outwardly bearing a 

 pear-shaped black spot, between which on the margin are a series of 

 very small black spots indenting the blue area. Underside, both 

 wings pale reddish, bearing an outer-discal dark line outwardly 

 defined with whitish, highly irregular and zig-zagged on the hind- 

 wing, less so in the forewing, where it is broken at the third 

 median nervule, its anterior short portion shifted outwards ; two sub- 

 marginal irregular broad indistinct dark red bands. Forewing with 

 a linear black spot close to the anal angle. Hindwing with some 

 scattered white scales towards the anal angle inwardly defined by 

 a fine black line, and a very narrow marginal white line, outwardly 

 defined by an anteciliary dark red line. 



Nearest to ? Z. pharyge, Hewitson, from Borneo, from which it is 

 at once separated by the much greater extent of blue (or green as 

 the case may be) coloration on the upperside of both wings, and es- 

 pecially by the absence of the submarginal series of five spots and 

 the trifid subapical spot on the forewing. In coloration and mark- 

 ings it appears to agree very closely with Deramas livens, Distant,*from 

 Singapore, but differs from it structurally in not possessing the 

 " cellular tuft of long hairs " present in the hindwing on the upperside 

 of that species. It is also near to Z. bradamante, Doherty, MS., from 

 Lower Siam,f but in that species the blue coloration on the upper- 

 side of the forewinp; is said to extend into the discoidal cell ; nor does
