the tip; prothorax nearly as broad as the head, truncate in 

 front, broadly rounded at the anterior angles, tapering on 

 the sides to the rounded hind angles, very slightly emarginate 

 at the hind, slightly turned up at the front margin, dark 

 castaneous, thickly hairy; meso- and metathorax light fuscous 

 in the middle; wings very long and broad, light ferrugineous 

 with darker nervures, forewings not quite so broad as the 

 hindwings and slightly shorter, the second nervure at the 

 front margin very stout and more darkly coloured, diffusely 

 clouded with yellowish below, hairy, joining with the first 

 nervure at the tip, and there forming a little yellow 

 spöt or »wing-mark»; mediana running through the 

 upper part of the-wing sending out three or four 

 branches into the space between mediana and 

 the second stout nervure, which run up to this 

 nervure; near the middle there is also a stouter 

 nervure running out from the second stout nervure, 

 turning sharply towards the tip and ending freely; 

 to the rear mediana sends out two or three mostly 

 forked nervures; cubitus with about 11 unforked 

 oblique nervures; in the two hindwings the vena- 

 tion is slightly different; in the left one mediana 

 runs very highly in the wing and sends out no 

 anterior branches, but gives off a freely ending 

 posterior branch already some distance before 

 the middle, and another unforked one further 

 out nearer the tip, in the right one mediana sends 

 Antenifa of ^^^ ^^"^ fairly well marked nervures in the direc- 

 imago of tion of the second stout nervure of the anterior 

 magnifious margin, which usually end freely into the mem- 

 MjöB.n. sp. brane; there are also two straight unforked ner- 

 vures running out from mediana between the middle 

 and the tip of the wing; cubitus of both hindwings sends out 

 11 oblique straight mostly unforked nervures to the hind- 

 margin; legs light brown; abdomen with 9 broad chitinous 

 dorsal plates and with two rows of light brown spöts on 

 the ven trål side; cerci short.
