ZONOSOMA — TETPHEEOMEEA. 45 



from the subcostal vein just beyond the cell, instead of being an independent vein ; radial of 

 secondaries emitted at a greater distance from the third median branch. From Pitasila it 

 differs in its more strongly angulated discocellular veinlets, in the upper radial of primaries 

 being emitted from the subcostal, and in the subcostal branches of secondaries emitted from a 

 footstalk, instead of at one point from the end of the cell. Type Z. interlectum.

Wings above white, semitransparent ; five short radiating basal streaks, two oval spots 

 near the base of interno-median interspace, a large irregular patch crossing the cell and termi- 

 nating in the first median interspace, a somewhat similar patch from inner margin to first 

 median branch, the apical area, a broad internally excised patch on the external border, only 

 separated by a longitudinal white stripe from the apical area, and a spot at external angle 

 olivaceous brown : secondaries with a spot at the base of cell, an elongated subcostal spot, 

 three large marginal patches, and one or two dots brown : body chrome-yellow ; the head, 

 thorax, and base of abdomen spotted, and the remainder of the abdomen transversely banded 

 with black. Wings below as above ; pectus chrome-yellow, spotted with black ; venter paler 

 yellow, with lateral series of black spots. Expanse of wings 1 inch 11 lines.

TRYPHEROMERA, gen. nov. 



Also allied to Pitasila, but differing in the possession of a short postdiscoidal cell in the 

 primaries, the third branch of the subcostal being united to the second at a short distance 

 beyond the cell, and emitting the fifth branch before its junction with the second ; the sub- 

 costal branches of secondaries emitted from a short footstalk, and the first median branch 

 considerably nearer to the second. Type T. plagifera.

Wings white, semitransparent : primaries with the veins more or less bordered with 

 brown ; a very irregular forked brown band from submedian to subcostal vein ; apex and 

 external border to first median branch brown, interrupted upon the margin by a series of white 

 spots ; a brown spot at external angle : secondaries with a very irregular abbreviated band at 

 the end of the cell ; six submarginal brown spots, the first and second widely separated, the 

 third very minute, the fifth and sixth small : body above white, washed with yellow at the 

 extremities ; thorax spotted with black ; abdomen with dorsal and lateral series of black dots ; 

 antennae black. Wings below as above ; pectus yellow at the sides, black-spotted ; venter white.
