AlTOthia .lord. gen. iiov. 



?. Kovpheatl with ;i thin ronical horn raised oblicini'ly forwards anil shai|ilv 

 trnni'iiteat the tiji ; diameter of liorn at tij) scarcely one-eighth of the breadth of 

 forehead. Antennae distinctly thickened beyond middle, with the extremity slender, 

 a little thicker than those of Aegocera titjnwi (Driice). Third joint of |ialpi naked, 

 almost longer than the second joint (?). 



Nenration : vein 9 to forewings arising a little beyond middle of 8 ; veins 3, 4, 5 

 as in Aegocera l,atr. and Rothia Westw. Second partition of median vein longer 

 than the respective portion of the outer margin. Hindwings with veins 3 and 4 

 ton-ether from lower angle of cell ; second partition of median nervure shorter than 

 lower discocelliilar veinlet. 



Type : Arrothia hlcolor Rothsch. sp. nov. 



Differs from Aef/ocera l,atr. and Rothia Westw. in vein 9 of the forewings 

 standing bevond middle of vein 8. instead of arising from between middle of 8 and 

 areole, and in the thin and long horn of the forehead. From I'ah IlUbn. it is dis- 

 tinguished bv the horn again, and by the long and naked third joint of the palpi ; 

 from I'ahia ,lord. gen. nov. by the shape of the frontal horn, the jiosition of vein 9 

 to the forewings, and bv the shorter second ])artiti(in of the median vein of llie 

 hindwings. K. J. 



2;!. Arrothia bicolor Kothsch. sp. nov. 



Female. — Upperside -. forewings, basal half huffish yellow, reaching at costal 

 margin 1 millimetre short of middle, while on inner margin it reaches one-fourth 

 short of the inner angle ; the outer edge of the yellow area is convex, and from base 

 of wing to half its extent is much shaded with black scales ; outer half of wing black. 

 Hindwings similar, but yellow area less shaded with black scales, black area narrowest 

 behind. 



Underside of wings as above, hut yellow area brighter and not shaded witli black 

 scales. 



Antennae, iialjii, head, underside of body, and last two segments of abdomen 

 black ; upperside of thorax orange and of abdomen yellow.

Arctiopais Jord. gen. nov. 



S ? . Forehead narrowed behind in S, almost parallel in ? , anteriorly convex with 

 a sharply raised circular ridge, of which tlie diameter is longer than a third the 

 breadth of the forehead. Antennae thicker than in Aegocera menelf (Cram.), thinner 

 than in Aegocera renu/irt (Cram.). Palpi long in either sex ; second joint strongly 

 hairy, third joint naked, about eight times as long as broad, of the length of the 

 basal joint of the foretarsi in c? and ?. In <^ hindtibiae and -tarsi and long sjutrs 

 of the former clothed with long hairs; in ? hindtarsi and long spurs of hindtibiae 

 almost naked. 



Neuration : costal nervure to forewing [jarallel to costal margin to a little beytnid 

 apex of cell, where it rather suddenly turns towards the margin ; vein 10 arising from 

 between middle and apex of areole; stem of 8.9 short; veins 3, 4, ;j as in Aegocera 

 Latr. and Rothia Westw. ; second partition of median nervure as long as the resjiective 

 portion of the outer margin. Hindwings as in Aegocera tnmeni Feld.
