Subfamily HYDRIOMENINAE. 

 Amoebotricha gen. nov. 



Agrees with Amoehe Hiib. in strncture and appearance, but the antennae of the 

 $ are fnlly bipectiuate. In the forewings the areole is double, 10 anastomosing 

 with 11 and again with 8, 9 ; 6 stalked with 7, 8, 9. In the hiudwiugs the 

 discocellular is angled below, the radial from the angulation. 



Type Amoebotricha yrataria Leech {Auticlea). 



13. Amoebotricha correlata sp. nov. 



Forewings : Whitish grey, suffused with dull rufous ; the chief lines fine and 

 black ; the rest dull rufous ; all in the main oblique and parallel to hindmargin ; 

 basal patch small, brown, edged with a black line angled on subcostal vein, and 

 with a paler space in middle ; the pale band following it mnch broader on costa 

 than at inner margin, with two pale brown lines through it ; inner edge of central 

 fascia from nearly one-third of costa to one-fourth of inner margin, more or less 

 ontcnrved between subcostal and median veins, followed by a brownish band, 

 containing two darker lines ; outer edge from two-thirds of costa to two-thirds of 

 inner margin irregularly dentate and crinkled, preceded l)y a brown band with two 

 darker lines ; the central space pale grey, not suffused with rufous, and containing 

 a distinct brown cell-spot ; band beyond pale rufous with a dark line near 

 edge of central fascia ; marginal area brownish rufous, containing three crenulate 

 darker brown lines, the outermost of which is blackish and edged by the paler 

 submarginal line, which between veins 3 and 4 forms a whitish V-shaped mark ; 

 an oblique black apical streak ; a dark marginal line interrupted by the veins ; 

 fringe rufous grey. 



Hindwings : dull whitish, suffused with rufous grey towards inner margin, 

 witli traces of lines on inner margin above anal angle ; an obscure cell-spot. 



Underside dull pale grey, speckled with darker, the markings of the forewings 

 showing through ; hindwings with the cross-lines marked by dark spots on the 

 veins ; cell-spots distinct. Head, thorax, and abdomen rnfous, the abdomen greyer 

 and paler. 



Expanse of wings : 37 mm. 



One c?, one ?, from Gifn. 



The antennae of the S have shorter pectinations than the type species grataria 

 and the hindwings are more produced at apex, as in Plerocymia, but the neuration 

 is typical. The insect bears great resemblance to -4. hatliata Hiib., under which 

 name I believe it has been recorded by Mr. Leech, ^1. if M. 1807. I. p. 659. 



14. Cidaria niveonotata sp. nov. 



Forewings : with all the dark markings olive-brown, all the pale markings 

 snow-white ; there is not a trace of any shade of yellow ; in arrangement of 

 markiugs the insect agrees exactly with C. perpiilclira Butler. 



Ilinrhriiigs : white, somewhat suffused with greyish ochreous towards the 

 hindmargin, and with traces of postmedian and submarginal curved lines. 



Underside agreeing with perpulckra.
