on the under side of the anterior face of the same joints is a 
similar, but less pronounced fring^e. The third leg has the ante- 
rior face of the femur pale, with two longitudinal dark lines, 
while at the distal end is a ^pale space having in the center a 
black dot. This pale space is in a constricted part, and a small 
apophysis comes off just above. All the spines on the third leg 
are light-colored. 
From Utah. This species is close to coccatum, the leg 
modifications being very similar. Coccatum, however, has, on 
the distal end of the anterior face of the tibia of the first leg 
two large, flattened black spines ; and has also, on the anterior 
and posterior faces of the femur of the first, toward the distal end, 
two stiff brushes of dark-colored hair ; while the first leg in fcstus 
is as above described, adorned with fringes of white hair. More- 
over in coccatus the clypeus is red, while in fcstus it is white.

d^. Length, 4.5 mm. Legs, 3412. 
Quadrangle of eyes wider behind, and nearly one-third wider 
than long. First row of eyes straight, the middle near together, 
the lateral a little separated, the latter less than half the former. 
Second row nearer the first than the third. Clypeus equal to 
diameter of middle eyes. Labium as wide as long, and half as 
long as maxillae. The sternum light yellow. The first leg has 
fringes of hairs, but they are not so long as in H. brunncus, or 
the other species with these ornaments. The. femur has fringes 
on the two sides, while on the patella and tibia, although 
there are hairs on the anterior sides, it is only on the posterior 
that they are well marked ; the hairs on the upper side of the 
femur are dark, the others white. Two long, thick, black spines 
come off from the anterior face of the tibia. The third leg is 
modified ; the femur, near its distal end, is constricted, the part 
beyond being somewhat enlarged and rounded ; on the face of 
this part is a black spot, and above it is a black ridge. The 
patella has two apophyses on its upper side. 
The cephalothorax is black. The clypeus and face of fakes 
are covered with white hairs. White lines, rather narrow, extend 
back along the margin, and on reaching the posterior end turn 
upward, as in other species of this genus, and merge with 
fawn-colored hairs that cover the cephalic plate. In some speci- 
mens all these markings are faw^n-colored. 
The abdomen is black, with a basal band running down the 
sides, and a second transverse band, narrower than the first, the 
two united, along the middle, by a wide band; the posterior
