 very good indeed, would leave no doubt in any case. The type is no

Ground color very deep brown to almost black. Collar with a 

 velvety black median line, tipped with blue green scales. Thorax 

 with three more or less obvious transverse lines that may be either 

 obscured or emphasized by green scales. Dorsal tufts of abdomen 

 tipped with green. Primaries more or less powdered with green 

 scales having usually the tint of verdigris, but sometimes more blue. 

 These scales, while they may be distributed throughout the wing, are 

 usually massed so as to form a diffuse shade beyond the t. a. line, a 

 conspicuous shading in and over the reniform, and venular marks in 

 the terminal space. The t. a. line is black, even, single, inwardly 

 oblique, with a slight and even outcurve in its course. Orbicular a 

 black dot, usually visible in the green shade band. Median shade 

 lines usually obscure. Reniform large, broad, defined only at the 

 sides by black scales or lunate marks. T. p. line slender, black, single, 

 outwardly bent over the cell, deeply but obtusely indented opposite 

 the reniform, rather evenly oblique below vein -f. S. t. line black, 

 inwardly diffuse, tending to become broken on the veins, more or less 

 completely interrupted from veins 5 to 7; in course it forms a little 

 inward angle on vein 4 and is then a little inwardly arquate on its 

 way to the margins. There is a series of green terminal dots on the 

 veins. Secondaries usually a little more brown to the black line 

 which is continuous with the s. t. of primaries, the disc crossed by 

 three more or less obvious undulating darker lines and powdered w it li 

 green; most obviously so at extreme base. Beyond this outer black 

 line, which tends to be inwardly diffuse, there is an edging of green 

 scales, and there is more or less green in the terminal area, tending 

 a little to mass at the anal angle. A series of green venular points 

 at base of fringes. Beneath rusty brown, powdery, a series of con- 

 spicuous whitish terminal dots on veins, and these white dots pre- 

 ceded by black points. Both wings with a dusky lunule and crossed
