line which crosses the eye region just above the anterior eyes. There 
is sometimes a less distinct transverse white line behind the dorsal 
eyes. The sides of the cephalothorax have a narrow white line at 
the margin formed by hairs which seem to be combed upward. 
The quadrangle of the eyes js wider than long, and slightly wider 
behind. The dorsal is as large as the lateral eye, and is placed higher 
on the caput, so that a straight line from its lower border passes above 
the lateral eye. The small median eye is equidistant from them, and is 
on a line with the middle of the dorsal eye. The anterior row of eyes is 
straight. The middle eyes are touching, and are more than twice as large 
as the lateral, which are separated from the middle eyes by about half 
their diameter. The clypeus is one-half as wide as the middle eyes, and is 
inclined. There is a white line just below the anterior eyes ; other- 
wise the clypeus is brown, and without hairs, excepting at the base of 
the falces, where there is a membranous ridge covered with white 
hairs. 
The palpus has white hairs excepting on the tarsus. The tibia is 
rounded on the, outer edge, but has no apophysis. The bulb is simple. 
The falces are not robust ; they are long and vertical, of the same 
color as the clypeus, without hairs. 
The maxilla' and lip are rounded. 
The sternum is wide and oval ; in color, brown with white hairs. 
The. anterior thighs are separated by more than the width of the lip 
at the base. 
The relative length of the legs is 1, 4, 2,:!, the first pair being slightly 
the stoutest. They are brown with whitish bars. There are femoral, 
tibial and metatarsal spines on the four pairs, those on the metatarsus 
of the fourth leg extending to the base. 
The abdomen is small, and pointed behind. The general color is 
brown ; there is a central longitudinal lighter band (sometimes 
wanting), on either side of which the abdomen is black. In the center 
of the abdomen are two transverse white bars, or large spots, one on 
each side. In front of these bars are one or two very small spots on 
each side. Behind the median bars are two indistinct light dots, one 
behind the other, in the middle line. Just above the apex are two 
white bars corresponding to the middle bars, but narrower. The sides 
are pale yellow. 
The venter is light brown, with indistinct longitudinal dark bands.
