Legs, $ 1432. In the large males the first leg is elongated, 
being longer than the second by the tarsus, metatarsus, and 
nearly all the tibia, while in the smaller forms it exceeds 
the second by only little more than the tarsus and metatarsus; $ 
1432. In both sexes the first leg is much the stoutest. 
There are two forms of males, the large form has the cephalo- 
tborax enlarged and widened, and is much less Hyctia-like in 
appearance than the small specimens. The general color of the 
male is dark brown, with some bronze on the top of the bead and 
more on the back of the abdomen. There are patches of white 
behind each dorsal eye, and shorter bars further back on the 
thoracic slope. On the top of the bead just above the space 
between the two large middle eyes is a short bar of white. A 
white line runs around the lower margin. The abdomen is 
bronze-brown, with a white basal band extending about the an¬ 
terior end and reaching one-third of the way back; there is a 
white band on either side of the middle more or less broken 
up into three or four bars; in some specimens there are white 
spots lower down on the side; venter pale; sternum and mouth- 
parts dark. First legs dark, other femora dark and also prox¬ 
imal ends of tibia and metatarsus of fourth leg, other joints 
of legs yellow. In some specimens the legs are nearly all 
dark, except the posterior patellae. 
The female cephalothorax is dark brown with the lower edges 
yellowish. There is a white median longitudinal band on the 
back of the abdomen, that reaches both ends; there is a black 
stripe on each side that does not reach either end, and the lower 
sides and venter are yellow, sternum pale, mouth-parts dark. 
Front legs orange-brown with spots or rings near the distal ends 
of the joints; other legs yellow, sometimes with indistinct 
brownish stripes at the sides.
