76 MR. H. R. HOGG ON SPIDERS 
rounded and there are no depressions separating the two; a 
longitudinal fovea reaches into the rear slope. 
The rear row of eyes is slightly recurved and stretches quite 
across the cephalic part. The median pair are less than one- 
third of their diameter apart and four times their diameter from 
the side eyes, which are rather more than half the same diameter 
across. The front median are one- oe wider than the rear 
median, twice their diameter apart, t, and 22 times the same from 
the rear, thus forming a trapezium ce as wide in front as 
posteriorly and slightly longer than broad. In a lateral direction 
they are the same distance from the side eyes as from the rear 
median. The front side eyes are the same size as the rear side, 
but half their diameter away, and the front and rear are each on 
a small separate tubercle. The clypeus is 14 times the width of 
one of the front median eyes. 
The mandibles are conical, kneed at the base, smooth and shiny. 
There are two teeth on the outer falx-margin, the anterior twice 
as long as the lower one; three on the inner margin. 
The maxille are convex and nearly square. The lip has a 
short, straight-sided base, the longer and very convex upper part 
curving to an obtusely angled point. 
The sternum is slightly convex, twice as long as broad, shield- 
shaped, hollowed in front, almost straight at the sides, and narrows 
rather suddenly to a point, which does not go between the con- 
tiguous rear coxe. 
“The abdomen is oval, 23 times as long as broad ; it is: sparsely 
covered with fine downlying hair and has upstanding spinous 
bristles on the upper side. 
The legs are thin and tapering, rather profusely covered with 
small brown spots, from which spring long upstanding spines 
and bristles on the patellar, tibial, and metatarsal joints and 
under side of femoral. Bristles only on the tarsa! joint. 
The palpi have the femoral joint incurved, the patella one-half 
as long as the tibia, and long spinous bristles on the latter.

Of L. Koch’s two species, Z. phthisica and L. tabida, this species 
more nearly resembles the former, but is two-thirds smaller and 
much brighter in colouring. The rear median eyes are larger
