NEW SPECIES OF HEMITHEIN.E (GEOMETRIN.E, Auctt.). 



By Louis B. Prout. 



Agathia dimota, Prout, nov. sp. 

 ? . 42 mm. Structure and coloration of i^isina, Butl., &c. ; 

 abdomen not appreciably crested, dorsally red-brown, with quite 

 indistinct pale spots. Fore wing with the red-brown markings 

 arranged as follows : — basal patch obliquely bounded, l)roadening 

 costad ; median band consisting of three large, well-separated spots, 

 the middle (between M^ and M'^) elongate distad, and scarcely enter- 

 ing the cell, hence appearing more out of alignment than in the 

 other known forms, the inner-marginal spot trilobed, a rounded lobe 

 standing between SM^ and the fold, a rounded (proximal) and a 

 smaller, less regular (distal) one between SM^ and inner margin ; 

 sub-apical band consisting of an irregular ])lotch from the costal 

 shade to R"-^, and a second one from R\ joining the terminal shade 

 below M^ ; terminal shade irregular in width, narrowing to a fine 

 line about R\ forming two rather large triangles on R^ and R\ and 

 extending rather broadly along inner margin to a distance of about 

 4 mm. from tornus. Hind wing with the red-brown markings 

 normally formed. Under side with the markings similar, but some- 

 what weaker and reduced in extent. 



Fiji. Type in coll. L. B. Prout, 



Anisozyga* vagilinea, Prout, nov. sp. 

 $ . 40 mm. Face and occiput green ; vertex white. Palpus 

 rather slender, less long than in typical Anisozyga, hardly over 1-|, 

 green, beneath white. Antenna on its dorsal (scaled) area white 

 proximally, green distally. Thorax and abdomen green above, white 

 beneath, abdomen with white anal end and white dorsal dots. 

 Fore wing longer and narrow'er, and hind wing with costa longer than 

 in typical Anisozyga. Colour rich deep bluish green, costa of fore 

 wing pure white, lines yellow, very slender. Fore wing with ante- 

 median line from costa near l^ase to inner margin just beyond one- 

 third, very oblique outwards, forming a tooth outwards in lower half 

 of cell, broadly outcurved in submedian area, and again oblique out- 

 wards to inner margin ; postmedian line from costa at three-fourths, 

 dentate and zigzag, approaching termen at R^ and M\ and to a less 

 extent at M'-^, then running basad for some distance along that vein 

 and sharply l)ent to run to inner margin at nearly three-fourths ; 

 termen with conspicuous pure white dots which extend into the 

 fringe ; fringe mostly dark grey, varied with reddish at tornus. 

 Hind wing similar, tinder side uniformly very pale green.
