marginal spots wilh wliicli its win>^s arc adorned are perfect, and its lovely green 

 colour is not in the least faded. It is a beautiful Geometer, closely allied to 

 Hemithea thymiaria, Gn. {xtrigata, MucU.), which it closely resembles, but its 

 marginal dark spots are larger and rounder, and its antennae are distinctly pecti- 

 nated in the male. Thalera fiinhriaUs,8voTp. {bupleuran'a, Sch'iii.) has an extensive 

 distribution in Central, Southern and Eastern Europe, and there appears to be no 

 " incompatibility " about its appearance in England. Guenee says he reared the 

 larva on Euphorbia cyparisaias. — C. G. B.]. 



A NEW SPECIES OF AREOPALA FROM BRITISH NEW GUINEA. 

 BY G. T. BETHUNE-BAKEE, F.L.S. 



AeHOPALA CHAMiELEONA, sp. nOV. 

 (? . Both wings deep metallic green, shading into brown in some lights, in 

 other lights the edges appear to be quite purple. Costa in the primaries finely 

 black. Fringes black. In the secondaries the costa and fold is broadly brown, 

 fringes black tipped with white at the apex, tail black tipped with white. Below 

 the primaries are purplish-brown, the purplish tint being very strong on the costa, 

 the median portion of the wing is occupied by a very large indefinite whitish patch, 

 extending nearly to the posterior margin below vein 2. Three increasing cell spots, 

 the third extending over tlie cell, above which is a small spot on the costa. Trans- 

 verse band composed of seven dark brown spots, the first three placed obliquely 

 outwards, the fourth shifted further outward, fifth very decidedly inwards, sixth 

 outwards, the seventh spot being small and obscure ; in the angle of veins two and 

 three is another dark spot ; submarginal band parallel with the posterior margin, all 

 the spots and bands are edged with whitish. Secondaries purplish-brown, strongly 

 purplish on the costa, the central area of the wing from the base to the submarginal 

 band whitish, a very small dark spot at the base of the costa, followed by two others 

 below vein eight, below these two are two other pale spots, those below that nearer 

 the basal being mere traces of the spots, macular transverse band composed of eight 

 spots, the first and second on the costa confluent and very dark, third and fourth 

 whitish, marked only by a pale brown edging and shifted outwards, the fourth being 

 beyond the third, fifth spot small, brownish, sixth darker brown, shifted outwards, 

 seventh angular spot inwards, eighth spot bisected, pale and indefinite, reaching up 

 to the internal vein, submarginal band lunular, evanescent at the apex and anal 

 angle, anal spot blackish, above which is a white stripe from the internal margin to 

 beyond vein three, which is irrorated above with bluish-grey scales. All the spots 

 and bands are edged with white, margin very finely dark, edged interiorly finely 

 with white. 



? . Primaries brownish-black, with a bright azure blue patch occupying most 

 of the cell, about two-thirds of the space beyond towards the posterior margin, 

 thence tapering basewards on to the inner margin, thus being in shape nearly a long 

 oval. Secondaries uniformly dark brown. Below, the pattern is just like the male, 

 but is more purplish in tone. Exp. alar., <? , 52, ? , 49 mm. 



The type is in the Tring Museum. This species, which is quite
