SCL.EROBUNIIS geu. uov. 

 Each of the four posterior tarsi has but one claw, wliich has on 

 its sides one or two curved projections. The palpi are shortei- than 

 the body, and the dorsal shield shows traces of the basal abdominal 

 segments. The eye-tubercle is rounded, situated near, but not quite 

 upon, the anterior margin. Otherwise the genus is similar to Sco- 

 iolemoii. S. robustus is the type ; two species are known to me. 



Color red, tips of legs black robustus. 



Color brown, tips of legs yellowish bruiiiiens.

Packard first described this under, the genus Scotolemon, after- 

 ward referred it to Phalangodes. His figure of the palpus on Plate 

 XII (Cave Memoir) is poorly drawn, there being no third joint 

 represented. The figure in the text (Cave Memoir, p. 48) is prob- 

 ably that of a male, the female has the second joint of the palpi less 

 gibbose than the male. The four posterior claws have one large 

 projection each side. The anterior femora have three or four little 

 tubercles, tipped with a stiff hair. 



It was described from Utah. I have it from Colorado and Wash- 

 ington State (Trevor Kincaid). 



ScIerobuiiU!ii bruiiiieus n. sp. Length 2 mni.--Color brown, paler on 

 the cephalothorax ; legs brown, a little darker than the body, their tips yellow ; 

 palpi yellow; venter brownish yellow. The eye-tubercle is rounded like robus- 

 tus, a little closer to the anterior margin than in that species. The dorsum and 

 legs have many little tubercles, each tipped with a stiff hair or bristle. These 

 are quite prominent on the tibise and patellfe of the legs; there are two of these 

 tubercles near the base of femur I. The palpi are very short, not half the length 

 of the body; joint two is not as enlarged as in robustus, about twice as long as 

 wide, and with two short projections below; joint four is barely longer than 

 wide, and has two projections below; joint five is nearly as long as joint two, 

 and has four or five projections below; the claw is nearly one-half as long as the 

 joint. The legs are very short; leg I not as long as the body, femur II not as 

 long as the cephalothorax is wide. The four posterior claws have two curved 

 projections each side.
