134 INSECTS OF SAMOA. 



in that the tornal region is separated from the rest of the wing and more or less 

 distorted. Besides E. eupitheciata, there are two unnamed species, virtually 

 indistinguishable in the $ but with different modifications, both inhabiting 

 New Guinea and the D'Entrecasteaux Is. 



15. Eupithecia (Mnesiloba) eupitheciata (Walker). 



Phibalapteryx eupitheciata Walker, List Lep. his., xxvi, 1720, 1862 (Australia). 

 Eupithecia intentata Walker, List. Lep. Ins., xxxv, 1676, 1866 (Sarawak). 

 Cephalissa delogramma Meyrick, Tr. Ent. Soc. Lond., 1886, p. 195 (Fiji and Tonga). 

 Eupithecia dentifascia Hampson, III. Het., viii, 117, t. 152, f. 12, 1891 (Nilgiris) 

 Ckloroclystis intentata (part.) Hampson, Faun. Brit. Ind., Moths, iii, 391, 1895 (Ceylon). 

 Eupithecia eupitheciata Hampson, Faun. Brit. Ind., Moths, iii, 398, 1895 (Khasi Hills, Nilgiris, 



Ceylon, Shan States, Australia, Fiji, Tonga) ; Prout, J own. Bomb. Nat. Hist. Soc, xxxi, 



319, 1926 (Upper Burma, Java, Sangir, Celebes, New Guinea). 

 Mnesiloba eupitheciata Warren, Nov. Zool., viii, 196, 1901 ; Turner, Proc. Roy. Soc. Vict., xvi, 



237, 1904 (Brisbane). 

 Mnesiloba seminiyra Bastelberger, Ent. Zeit., xix, 76, 1905 (Assam). 



Upolu: Malololelei, 2 $$, 22, 24.ii.1924 ; 1 2,000 feet, 24.vi.1924 ; 

 3 2,000 feet, 21. iv. 1925. 



With the exception of the £ taken 24.vi.1924, which is fully normal in 

 size, the Upolu examples are rather small. All have the hind wing more or less 

 pale and the subapical shading of the fore wing moderately bright, so that we 

 perhaps have to deal with a local race. But the species is everywhere extremely 

 variable, and so precisely similar is the range of forms exhibited by it that I 

 should hesitate to make any geographical separations in default of very plentiful 

 and very perfect material. The median area of the fore wing is particularly 

 inconstant, and may be darkened either : throughout ; only in its posterior part 

 (ab. seminigra Bastelberger) ; in its anterior and distal part, forming a some- 

 what triangular shade, with its base on the costa and its apex in the angle of 

 the postmedian line about M 1 ; at its proximal and distal edges ; or it 

 may remain wholly whitish. Two of the Samoan specimens belong to the last- 

 named, the others approximating to the triangularly -marked form, though in 

 varying degree, in no case with the triangle well-defined proximally and 

 posteriorly, nor very completely dark-filled. 



I have given the hitherto recorded range under the synonymy, but have 

 also received specimens from Peninsular Siam, Pahang and Sumatra.
