20. Hemistola antigone spec. nov. 



(J, 34 mm. ; ?, 36 mm. Face deeij red. Palpus in 3 not reaching beyond 

 frons, in $ with third joint a little longer, reaching beyond Irons ; deep red, be- 

 neath paler. Vertex pale green. Antenna in cJ with short pectinations to about 

 the 27th joint, the last few mere teeth, the longest of the inner series scarcely 

 longer than, of the outer series .scarcely three times as long as, the diameter of 

 the shaft ; in $ not pectinate. Thorax above green (abdomen in both examples 

 discoloured ; apparently with some red markings dorsally). Hindtibia in (J 

 dilated, with hair-pencil. 



Forewinq with apex rather sharp, termen almost straight in the <J, rather 

 more bent in the middle in the $; SC free, R' stalked or separate; bluish 

 green, a little duller than in ruhrimargo Warr. ; costal edge very narrowly 

 ochreous, with dark dots ; first line slightlj^ indicated, apparently about a.s in 

 ruhrimargo ; cell-dot sharp, red mixed with black, with a slight pale circum- 

 scription ; postmedian line indistinct except near hindmargin — where it fonns 

 a deep lunule inward — ^and as white dots on the veins, apparently formed nearly 

 as in ruhrimargo, but more distally placed ; neither line accompanied by any 

 red dot ; terminal line red, mixed with black, slightly interrupted at the veins ; 

 fringe proximally white between the veins, with longer or shorter reddish marks 

 opposite the veins ; distally apparently reddish grey (sonie\\hat damaged). 



Hindiving narrower than in ruhrimargo \^'arr. and fuscimargo Prout (Nov. 



ZooL. xxiii. 16), abdominal margin long ; tail at R' rather strong ; C anasto- 

 mosing slightly with SC near base, M' almost connate with R' ; as forewing, 

 without antemedian line. 



Underside whitish green, the discal dot.s shghtly indicated ; costal edge 

 of forewing light ochreous, more feebly dotted than above ; terminal line and 

 fringe nearly as above. 



Khasis, Maj^ 1896. 3 type and a 9 in coll. Tring Museum. 



The pale-ringed discal dots, .somewhat recalling Cyclothea disjuncta Walli., 

 distinguish this from all other species of Hemistola. 



21. lodis rhabdota spec. nov. 



(J ?, 33-35 mm. On an average larger than iridescens ^^'arr. Palpus in £ 

 with third joint a little shorter, antenna in S pectinate to about one-half its 



length (in iridescens to about two-thirds), the branches not quite so long. 



Forewing slightly broader, the termen less oblique ; SC connate (in one 

 example just from cell), free, R' stalked ; the white ground-colour rather less 

 opalescent than in iridescens, more tinged with green ; costal margin less dark ; 

 bands broader, the postmedian less obUque anteriorly, rather more dentate. 

 Hindioing with corresponding distinctions. 



Khasis, Februarj' — March 1894. Type in coll. Tring Museum. Also a ,i 

 from Sikkim (Knyvett). 



Intermediate in colour towards coeruleata Warr., which is still greener, has 

 nearly the shape of the present species, but the antennal structure of iridescens, 

 and is distinguished from both by the postmedian line of the forewing, which 

 is rather deeply sinuate inward between the radials and moderately between 

 M« and SM«.
