Subfamily TEPHROCLYSTIINAE. 



15. Ardonis olivata sp. uov. 



Difters from tl'.e type species ^1. chlorophilata VVlk. in being dull olive-green 

 instead of clear grass-green. 



Foirwinys : basal patch dark green, edged and traversed by a darker green line; 

 jiale band between it and central fascia with the hair-like line down it nearer the 

 outer edge ; central fascia dark olive-green, its inner half formed by a curved deep 

 green band, followed by a pale and then a dark green line, the tint again deepening 

 towards the outer edge which is bluntly angled at veins 4 and G ; all these markings 

 are oliliquely curved inwards below, and are nearer base on inner margin than on 

 costa ; pale baud following central fascia with the traversing dark line close to its 

 inner edge ; two diffuse curved dark green submarginal shades ; marginal line 

 black, broadly interrupted at the veins ; fringe dark green. 



Ilintlirinqs : dingy greyish ochreous, nacreous ; without scales, but the hind- 

 margin narrowly greenish tinged ; marginal line and fringe as in forewings ; the 

 oval patch of mealy scales in the cell brown. 



Underside of both wings dull grey, with traces of darker grey curved cross- 

 lines : forewing with the cell nacreous, very glossy ; the patch of scales below 

 median snuif-br<iwu ; ]iindwiiigs witli five curved dark grey lines : three towards 

 liase, the other two marginal. Head, thorax, and abdomen olive-green ; the thorax 

 darkest ; palpi green speckled with Mack. 



Exjianse of wings : 'S2 mm. 



1 cJ from .Sevan Mally, a tea estate 40 miles east from Quilou, on the western 

 side of the Cardamom Ilills, South ludia. 



Mnesiloba gen. nov. 



Forewings: triangular; costa nearly straight ; hindmargin curved. 



lli»(ltvhigs : small, their inner margin concave, the outer margin in S with 

 a small indentation near anal angle. 



Palpi porrect, roughly haired. Forehead witli projecting tni't of scales below. 

 Antennae simple, pubescent ; tongue and frenulum present. 



Nenration : forewings, cell one-half of wing ; discocellular straight, riither 

 oblique ; first median at two-thirds, second ch)sc before third ; radials normal ; 

 7, 8, '.I stalked from a little before end of cell, lu and 11 far l)ack, 10 anastomosing 

 with 11 and again with 8, 0, forming a long narrow second areole ; hindwings, 

 discocellular oblique, radial from the centre ; costal anastomosing with subcostal 

 for half the length of cell ; G and 7 stalked ; medians as in forewings. 



This genus is proposed for the insect first described by Walker, xxvi., p. 17:iO, 

 as J'liilxd((j)tei:i/x eiipithcciata from Australia. In the Tr. E. S. 1886, p. l'.)5, 

 Meyrick describes 2 ? ? from Fiji and Tonga as Cephalissa delogramnia, and a 6 

 from Queensland as Lohophora ddogranima iu Proc. Linn. Soc. New Sontli Wales, 

 I8'.i0, p. 807. Lastly, Hampson again describes it as Eupithecia dcnti fascia m 111. 

 licp. Het., viii., J). 117, PI. I.j2, fig. 12, from the Nilgiris. The minuti'iiess of the 

 first additional ixdl evidently escajied his observation. The small i)rominence at the 

 anal angle of the S seems to me entirely difl'erent from the basal lobe that exists 

 in Loho/ihoia and its allies ; and I would place the genns close to Euci/mafoge Hiib., 

 with which it agrees iu ueuratiou. Iu the '' Characters of Uudescribed Lepidoptera
