HE WEEKS — THREE NEW BUTTERFLIES x Ee 
Upper surface of hind wings bears no markings, the borders being the same 
as on fore wings. Inner margin bears a quantity of blackish gray hairs. 
Under surface strongly resembles that of Zasata rosamonda Weeks. The 
tip of fore wing is dark mouse color. The border of hind margin is the same 
as the upper surface, and the interspacial black lines just within the border 
are repeated. The inner half of the wing is dark mouse color; the discoidal 
space has three black lines, the outer one extending downward to inner margin. 
The rest of the wing is Quaker gray, very slightly pinkish, forming a band 
extending from anal angle upward and thence across to costa. 
Under surface of hind wings is much the same, except that the upper angle 
has no dark markings, and the Quaker gray band—it may be called the 
ground color—shows strongly through the lighter mouse color of inner half 
of wing. 
Described from ten specimens in my collection, taken five days 
travel north from Cochabamba, in September, 1899, by my col- 
lector, Mr. William J. Gerhard. 
Heliconius spadicarius sp. nov. 
Habitat: Bolivia, near Coroico. Expanse: 3.50 inches. 
Head black, with four light yellow spots at “collar”; also a yellow speck 
above each eye. Palpi black above, light yellow beneath. Thorax, above, 
black, with a light yellowish white spot at base of each wing, and between 
these, close to “collar,” two more; these are grayish in some specimens. 
Centre of thorax, above, tending to dark grayish, near end a semicircle 
of light yellowish. Thorax, below, black, with a light yellow dash running 
from shoulder to lower end. Abdomen black above, light yellow below; a 
light yellow thread runs from thorax joint to tip just above the yellow under 
side. Fore legs, above, black; below, light yellow; other legs black. An- 
tennae black, turning to light tawny half-way to club. 
The basal portion of upper side of fore wings, from a line drawn from centre 
of costa to lower angle, is dark tawny. Costa black. Through centre of dis- 
coidal space, starting at base, is a black dash, broadening out to a well-defined 
spot at longitudinal centre of the space. The black of the costa suffuses 
downward at end of the discoidal space, forming a band one quarter inch 
wide, running to lower edge of the discoidal space. Outside of this is a series 
of yellow, elongated spots, the first at the costa, the fourth extending out 
nearly to hind margin and having a black spot or dash at its inner end, bor- 
dering discoidal space. In interspace below this spot is another, of anvil 
shape, bordered on its inner and outer edge by black dashes. These black
