towards lower angle. 
Upper side of hind wing the same. 
Under side of fore wing dark brown with golden lustre. Basal area dusted 
with lustrous green scales as on upper surface. Inner marginal area very light 
bi'own. 
Under side of hind wing the same as upper surface. Taken in January, 
1900. This is practically indentical with T. pervivax, Hubn. excepting that 
pervivax has a very prominent semitransparent band crossing the fore wing. 
The specimens in hand show no indication of such a band except in one instance 
where I noticed a slight dot. It would be unsafe to create a new species and 
the advisability of naming a variety is doubtful. There is a specimen in the 
Godinan collection un-named. 
Thanaos parkeri sp. nov. 
Habitat: Suapure. A'enezuela. Expanse: 1.60 inches. 
Head, thorax and abdomen above, very dark brown. Antennae black with 
white annulations at base of each joint. Club black above; tawny brown be- 
neath, and ai^proaching white towards base. Legs nearly black. 
Upi>er side of fore wing very dark brown with slight grayish dustings. 
Near the base is a slight suggestion of gray dusting running from costa 
towards inner margin scarcely perceptible. The interspaces beyond, in centre 
of wing and the centre of discoidal space show a slight gray dusting. Outside 
of this in a line from costa downwarils to lower sulnnedian nervule, is a slightly 
prominent irregular band of gray dusting, broad at costa but diminishing and 
disappearing towards lower sulnnedian nervule. In apical area outside of this 
band are four subcostal semitransparent white dots. Hind margin edged with 
a dark thread, and the hind marginal area has a series of interspacial grayish 
dashes from costa down to inner margin, well within the margin, and hardly 
noticeable. 
Upper side of hind wing dark brown. The only marking is a suggestion 
of light brown dashes in interspaces running from upper angle to a point just 
above anal angle on inner margin. Hind margin edged with a dark thread. 
Fringe is generous and near upper angle is edged with white. 
Under side of fore wing dead dark brown. The gray dustings of upper
