June 3°) WEEKS — UNFIGURED LEPIDOPTERA 7 
1900 
Colias hecate sp. nov. 
(Plate I171.) 
I have received the following description, in manuscript, from 
Dr. Herman Strecker, and have his permission to publish it here. 
Habitat: Congo, West Africa. Expanse: 1.88 inches. 
Size and shape of Lurytheme. 
Male.— Body, above, black with yellow hairs. Some red or pinkish hairs on 
the head and collar. Wings above pale yellow orange; at costa of secondaries 
lemon yellow. Primaries with a black marginal band, which is parallel with the 
exterior margin from the inner margin to middle of wing, whence it widens to 
the costa at a point about one third in from the apex. A good-sized black 
discal spot. Secondaries with a moderate black marginal band, widest from 
middle toward the apex and narrowing toward the anal angle, which it 
does not reach. A pale orange geminate discal spot. Fringe of primaries 
pinkish brown, paler at inner angle; of secondaries more yellowish. Under 
surface lemon yellow, costa edged with pink. On primaries two small brown 
spots on costa, and four submarginal ones. A black discal spot, centred with a 
white dot. Secondaries with silver discal spots encircled with reddish brown, 
the anterior one much the smallest. A brown mark on the costa, and a sub- 
marginal row of small brown spots, one in each cell. 
Female.— Lemon yellow, primaries with a very pale orange shade on the inner 
part of disk between the median vein and inner margin; some black scales 
along the costal margin and at base. A black marginal band much as in the 
male but wider on its inner half, and enclosing three inconspicuous yellow 
spots, one between veins 2 and 3, and two, almost geminate, half way between 
the latter and the costa. A black discal spot. Secondaries with a black exte- 
rior margin more even in width than in the male but not as sharply defined on 
the inner edge. A double orange discal spot. All fringes pink. Under surface 
as in the male, but the discal spots smaller, the anterior one of secondaries 
being little more than a dot. 
Types, two males, one female, from Ovim-Bunda, Congo, West 
Africa. Except the red C. e/ectra of the Cape regions, this is the 
only African Colias so far known to occur south of the Great 
Desert.
