base. It curves regularly outward, being most distant from 

 base at vein 4, thence it curves inward to the inner margin. 



In sinndaria this line commences almost exactly in the mid- 

 dle of the costa proceeding towards the centre of the outer 

 margin in an almost straight line to vein 5, then turning at an 

 obtuse angle and running in a straight line to the inner margin. 



On the under side the difference is greater. An extradis- 

 cal line divides each wing into two parts. The outer half of 

 each wing is very dark on the hind wings nearly black. 



The course of the extradiscal line on the hind wings is 

 peculiar. The ends of the line are not at the middle of the 

 costa and the middle of the inner margin. From each end the 

 lines curves regularly towards outer margin, forming an acute 

 angle on vein 5, recalling the median line on the underside of 

 secondaries in Cccnocalpe annellata or Marmopteryx tnarmorata.

6. Eupithecia helena n. sp. 



Palpi long and bush}', white, with a few black scales, tip black. 

 Front, head and thorax dull white, with slight ochre tint. Abdomen 

 same color, but with rather more of the ochre tint on the anterior 

 segments ; the last two segments greyish. Dorsal tufts small, black. 

 Fore wings dull white, overlaid with brownish scales. Basal area 

 blackish. Basal line double. Intradiscal line double, distinct on 

 costa, faint across the wing, regularly curved, parallel with basal line. 

 The space between basal and intradiscal lines is occupied by a broad, 

 rusty brown, regularly curved band. Extradiscal lines double, white, 

 wavy, very conspicuous on the costa, divided by a fine brown line ; the 

 inner white line is marked on inner side on each vein by a black dot. 

 The course of these extradiscal lines is straight from the costa to vein 7, 

 then evenly rounded out to vein 2, then in 2 or 3 scallops to the inner 

 margin. Discal spots large rusty brown. Beyond the extradiscal line 

 there is a rusty brown band which is almost continuous from costa to the 

 inner margin. This is bounded by a distinct, white, wavy, submarginnl 

 line. The marginal space is dark grey. Marginal line distinct, black, 

 hardly interrupted at the veins. Fringe long, color of the wings, marked 

 at base with faint brown spots. Hind wings, color of fore wings, crossed 

 by 7 or 8 dusky grey indistinct lines. The outermost being the most 

 prominent. A submarginal white line and a marginal black one as on 

 fore wings. Discal spot lengthened, blackish. Beneath, white, with 

 indications of all the lines as alone. The rusty br< \\n bands of the upper 

 side show as dark grey bands below, and there is in addition a rather
