62. Hyperythra phantasma, sp. n. (No. 35). 



Sordid creamy whitish or very pale stone-colour ; wings sparsely 

 speckled with grey and crossed by three equidistant olivaceous 

 slightly arched lines, basal area to the second line slightly obscured, 

 external area from the third line to the margin washed with oliva- 

 ceous greenish ; tegulae and abdomen sHghtly darker than the rest 

 of the body. Wings below cream-colour, the external area slightly 

 darker and limited by a grey line rej resenting the third line of the 

 upper surface ; body brownish white. Expanse of wings 1 inch 

 6 lines. 



One female. Kurrachee, February 1880. 



Said to be rare. It is hardly likely to be the female of H. swin- 

 koei, the latter being taken in November and having a more typical 

 style of coloration with less regular lines across the wings. H. phan- 

 tasma is an unusually colourless species, the under surface (which 

 is usually far more brilliant than the upper surface) being almost 

 uniformly creamy whitish. 



Geometric;. 



LoxocHiLA, gen. nov. 



Allied to Tanaorhhius and Geometra. From the former it differs 

 in its more perfectly pectinated male antenufe, its shorter palpi, less 

 falcate primaries, and in the second and third median branches of 

 these wings being emitted at the same point from the inferior angle 

 of the cell ; from the latter in its shorter palpi, the shorter dis- 

 coidal cell of the primaries, and the simultaneous emission of the 

 median branches noted above ; the male antennse are scarcely so 

 fully pectinated as in Geometra, as the apex remains bare. Type 

 L. smaragdus {Tanaorhinus smaragdus, Butl.). 



63. LoxocHiLA mutans, sp. n. (No. 28). 



Wings above pale sandy buff, probably dull sea-green when fresh 

 (showing traces of this colour in some specimens), crossed in the 

 middle from second third of costal margin of primaries to just beyond 

 the middle of the abdominal margin of secondaries by a white line 

 bordered internally by a line darker than the ground-colour ; 

 primaries with a second divergent transverse white line across the 

 basal third ; fringe of all the wings white : thorax of the same 

 colour as the primaries ; abdomen white ; crest of head white ; 

 antennse sandy yellowish. Under surface white, the costal borders 

 of the wings, apical area of primaries, and a tint on the pectus and 

 legs saudy buff, probably green in fresh specimens. Expanse of 

 wings 1 inch 8-10 lines. 



One specimen. Neilgherries. 



In addition to the example sent by Major Swinhoe (which shows 

 no trace of the original green coloration), we have three specimens 

 formerly in the collection of Mr. Norris ', which show distinct 



^ Some of the species in this collection were described by Walker ; and the 

 types of the Indian forms were purchased by Mr, Moore.
