Chickering — Genus Tmarus 
233 
4 in order of length ; first and second more than twice as long as third 
and fourth; numerous trichobothria observed on tibiae, metatarsi and 
tarsi. Palp : reminiscent of the palp of T. ineptus O. P.-Cambridge 
and T. intentus O. P.-Cambridge as these species are now under- 
stood; essential features shown in Figures 4-6. Abdomen: with many 
spines; about one third from base there is a pair of small, low, dorsal 
tubercles each topped by a slender, stiff, somewhat recurved spine; 
about two thirds from base there is a median, low tubercle correspond- 
ing to the pronounced posterodorsal tubercle of the female; shortly 
anterior to this reduced dorsal tubercle the abdomen is somewhat 
widened ; otherwise apparently typical of males of the genus. Color in 
alcohol : carapace with dorsal area yellowish in general but with small, 
irregular, reddish brown spots and streaks extending from median 
margins of tubercles bearing PLE to top of posterior declivity; clypeus 
about the same ; lateral sides a mottled, darker, reddish brown ; central 
part of posterior declivity yellowish with a central darker spot. 
Chelicerae: front surface with yellowish margins, somewhat darker 
centrally. Sternum yellowish with small, irregular, darker spots. 
Maxillae and lip yellowish with variations. Legs: light brownish in 
general ; with brownish, yellowish and reddish spots ; first two pairs of 
femora conspicuously spotted with irregular brownish and whitish 
spots; first two pairs of metatarsi and tarsi somewhat reddish. Abdo- 
men : dorsum yellowish white with many irregular, small darker 
spots; venter light brownish centrally, flanked by yellowish white 
areas. 
Female paratype. Total length, including somewhat porrect cheli- 
cerae, 3.84 mm. Carapace 1.62 mm long; 1.56 mm wide; about .81 
mm tall; with numerous spines each of which arises from a small, 
chitinized tubercle ; with a series of grooves radiating over the lateral 
regions from the dorsolateral areas. Eyes: lateral ocular tubercles 
large; with a deep depression separating ALE from PLE; viewed 
from above, posterior row recurved, anterior row slightly so, exclusive 
of the very convex lenses of ALE ; viewed from in front, anterior row 
slightly procurved, measured by centers. Central ocular quadrangle 
wider behind than in front in ratio of about 19 : 12; wider behind 
than long in ratio of 38 : 31. Posterior row occupies about 11/12 of 
width of carapace at that level. Ratio of eyes AME : ALE : PME : 
PLE = 4 : 10.5 : 7 : 9.5. AME separated from one another by 
nearly four times their diameter, from ALE by a slightly greater dis- 
tance. PME separated from one another by slightly more than 3.5 
times their diameter, from PLE by about 4.7 times their diameter.
