Psyche 
[Juue 
half a diameter ; abdomen oval, brown, dorsum flat, clothed 
with brown and white hairs in no distinct pattern ex- 
cept for three dark chevrons on the distal half and large 
spots of white hairs each side, venter pale with many 
white hairs ; legs, 4-1-2-3, pale, with rather vague darker 
rings on the tibiae and patellae, spines, I and II pairs, 
tibiae, ventral, 2-2-2, metatarsi, ventral, 2-2, III and IV 
tibiae, dorsal basal spine and median and apical whorls 
of spines ; palpus, about as long as cephalothorax, 
brown, femur with a dorsal crest of white hairs, patella 
and tibia of about equal length, tibia about as wide as 
long with a retrolateral fringe of long white hairs and 
a prolateral brush of dark hairs so that the joint ap- 
pears very broad, tibial apophysis a very slender dark 
shiny spur that extends beyond the middle of the cym- 
bium, cymbium little longer than the tibia, embolus starts 
at the lower margin of the bulb, follows the contour of 
the cavity and ends as a slender free tip at the tip of the 
cymbium; in the bulb a conspicuous tube forms a IT- 
sliaped loop. 
Holotype c? Mexico ; Acapulco, on grass at beach, 18 
December 1944 (S. Jones). 
The genus Tomis was based by F.O.P. -Cambridge on 
a single species, Tomis palpalis F.O.P.-Camb. from 
Teapa, Mexico. Tomis jonesce is separated from the 
genotype, by the slightly smaller size, the mass of short 
white hairs on the ocular area with the median stripe of 
longer dark hairs, the four teeth on the upper margin of 
the fang groove that are not grouped on a lobe or proc- 
ess as figured by Cambridge, and the U-shaped tube in 
the bulb of the palpus. Both species have the slender 
shining tibial apophysis and a very broad tibia of the 
palpus. 
The stripe of black hairs on the ocular area is very 
conspicuous and if present on the genotype, would have 
been noted by F.O.P. -Cambridge.
