CALYPTIS. — PLECOPTEBOBES. 141 



nervure, defined above by a curved white streak and below by a 

 white streak on vein 1 extending to near termen ; two faint oblique 

 antemedial grey striae from costa ; orbicular very indistinct and 

 oblique, defined on inner side by grey and on outer by the curved 

 white streak ; reniform very narrow and oblique, defined by white 

 and with whitish line in centre, a narrow oblique white medial band 

 fi'om it to vein 1 ; a large deep cupreous apical patch defined below 

 by an oblique white streak to near termen below vein 6, met at 

 vein 6 by a slight white streak from the reniform ; another very 

 large oblong deep cupreous patch beyond the reniform and medial 

 band extending to near termen below vein 5 on which there is a 

 white streak defining its upper edge, its lower edge defined by the 

 white streak on vein 1 ; the postmedial line below vein 6 very 

 indistinct, dark, waved, excurved below vein 3 and just above vein 1 

 retracted to lower angle of cell and the medial band ; subterminal 

 line white, slightly excurved above vein 6 on the apical patch, 

 below vein 5 faint and forming the outer edge of the cupreous 

 patch ; a white line at base of cilia and line near tips. Hind wing 

 brown with a cupreous gloss ; cilia with whitish line at base and 

 whitish tips ; the underside irrorated with greyish, a curved post- 

 medial line and slight white lunules before termen above and below 

 vein 5.

 vertex of head and rather broadly scaled, the 3rd long ; frons smooth, witli 

 tuft of hair above; eyes large, round; antenna of male minutely ciliated; thorax 

 clothed almost entirely with scales and without crests ; tibiti; smoothly scaled,

 3, 4 from angle; 5 fully developed from just above angle; 6, 7 from upper 

 angle ; 8 anastomosing with the cell near base only.

costa to vein 4, then incurved.
