Mamestra Farnhami, Orote, Plate 3, fig. 2, 5 . 



t, 2 . — Eyes hairy; fore tibiae unarmed; antennae simple, very shortly ciliatc 

 beneath in 3 ; palpi porrect, with small projecting third article ; abdomen 

 with moderate basal tufts. A little smaller than Mamestra grandis ; remarka- 

 ble for the unusually sharply defined W-mark, the varied tints and the pale 

 oblique streaked shade on median nervure below the ordinary spots, in which 

 character it simulates Prodeiiia commelinae. The ground color of the fore 

 wings is blackish with a dark green cast, and obtains over the median and 

 terminal spaces. Subterminal space, median space along internal margin, 

 and basal space before the t. a. line, pale reddish brown with a purple reflec- 

 tion. T. a. line thrice waved, geminate, with pale internal shade ; basal half- 

 line similar. Orbicular outwardly oblique, moderate, pale, with a dark shaded 

 center, finely ringed with black. Reniform elongate, incompletely ringed, 

 with an inner shaded annulus. T. p. line forming a single inward arcuation 

 opposite the cell ; below vein 5 it runs straightly, interspaceally lunate, to 

 internal margin. Subterminal line very distinct, pale, commencing with a 

 pale yellowish apical patch and forming the usual W-shaped mark, the 

 points closing on the extremities of veins 3 and 4, preceded on the subter- 

 minal space by interspaceal dark dashes before which are pale scale points. 

 Terminal line black ; fringes with a pale basal line and interrupted at the 

 Extremity of the nervules with pale scales. Hind wings pale with blackish 

 borders and discal mark ; veins marked with dark scales ; terminal line 

 forming broken black interspaceal marks ; fringes pale subtestaceous. Be- 

 neath pale, faintly reddish, powdered with dark scales and with a continued 

 common extra discal line and partly annulate discal marks ; on primaries the 

 pale subterminal line feebly reflected.
