18/6.] MR. A. G. BUTLER ON NEW-GUINEA BUTTERFLIES. 767 



Primaries above deep coppery brown, the costal and apical half of 

 primaries and the submedian area of secondaries almost black, with 

 very feeble bluish reflection ; primaries with a large trifid subapical 

 white spot, washed with lilac ; two submarginal white spots imme- 

 diately below it : secondaries with the costal area shining brownish 

 grey ; the upper half of "the cell and the area immediately above it 

 sordid whitish. Wings below more uniform in colour than above ; 

 primaries with the interno-median area whitish ; five subapical spots 

 in an oblique series, the third largest : secondaries with two sub- 

 apical bluish dots, the lower one barely visible ; base of wings and 

 pectus black, white-spotted. Expanse of wings 2 inches 2 lines. 



The smallest species hitherto described. 



Tenaris jamesi, n. sp. (Plate LXXVII. fig. 4.) 



Wings semihyaliue, snow-white, with a diffused basal ochraceous 

 nebula ; primaries with the costal area and apex black-brown, exter- 

 nal angle irrorated with sooty brown : secondaries with the apex and 

 apical border sooty brown ; a large subapical ocellus visible from 

 transparency of the wing ; a large ocellus on the first median inter- 

 space black, with white-dotted lilac pupil and diffused yellowish iris 

 with greyish edge (round which is seen a pale ochraceous zone, owing 

 to the transparency of the wing) : head and collar black ; antennae 

 black, palpi orange with black tip, thorax grey, the prothorax brown- 

 ish ; abdomen ochreous. Primaries below nearly as above, but 

 without the sooty external angle ; secondaries without the sooty apex 

 and border, with two large ocelli, one subapical the other as above, 

 black irrorated with blue scales, with large white pupils and broad 

 grey-bordered ochreous irides. Pectus and legs black. Expanse of 

 wings 4 inches 3 lines. 



Allied to T. rayloecha. 



Atella cervina, n. sp. (Plate LXXVII. fig. 5.) 



Above reddish tawny, paler in the female, with blackish markings 

 as in A. armaria, but more pronounced ; wings below also much as 

 in A. armaria, but the basal area not washed with lilac in either sex, 

 the black spots more pronounced, the whitish discal and submarginal 

 spots more silvery, and the submarginal zigzag ochreous band much 

 more irregular : expanse of wings, <$ and £ > 2 inches 5 lines. 



Though nearly allied to T. armaria, this species is much larger, 

 darker, more heavily bordered and spotted with black-brown, and 

 the basal area below differs markedly in the absence of the strong 

 lilac wash which is persistent in the Aru species. 



Heterocera. 

 Celerena, Walker*. 

 Allied to Celerena (of Lepidoptera Heterocera) ; wings larger, more 



* Mr. Walker altered the type of his genus Celerena, originally described in 

 the ' Transactions of the Entomological Society,' from C. divisa to C. sobria; as 

 the two species are not congeneric, I would propose for the latter (which is the 

 type of Celerena in the Lepidoptera Heterocera) the name of Craspedosis, n. gen.
