1919] Chamberlin: Western Spiders 257 



Male — The palpus very similar to that of C. arcuaia, but differing 

 in details. 



Length of female, 9 mm. Length of cephalothorax, 3.2 mm. Length 

 of tib. + pat. I, 3 mm.; of tib. + pat. IV, 3.1 mm. 



Type— M. C. Z. 470. Utah: Chalk Creek, elevation 

 8,000 ft. 



A species much resembling the Louisianan C. liidvoiciana 

 Simon in coloration, proportions and general structure. It 

 may be distinguished in having the posterior median eyes 

 much farther apart than from the laterals, instead of these 

 eyes being equidistant, in having three spines on the anterior 

 face of tibia I instead of but two; metarsus I with two spines 

 on anterior side, instead of but one, etc. 



Cicurina utahana sp. nov. 



Female — A small form with carapace and sternum yellow, the legs 

 more brownish especially distad. Carapace glabrous or nearly so. 

 Abdomen grey, immaculate, the epigynum light chestnut. Lower 

 margin of furrow of chelicera armed with four teeth, a minute fifth one 

 detectable on one side in the type. Posterior row of eyes straight- 

 median eyes smaller than the laterals, nearly their diameter from the 

 latter, slightly farther from each other; posterior medians obviously 

 smaller than in arcuata and the spacing of the posterior eyes more 

 nearly equidistant. Epigynum, Plate XIX, Fig. 8. 



Length, 5.2 mm. Length of cephalothorax, 2-}- mm. Length of 

 tib. + pat. I, 1.8 mm. 



Type— M. C. Z. 467. Utah: Millard Co.; Pine Canyon. 



Cicurina utahana anderis subsp. nov. 



Female— This form very much resembles in size and coloration the 

 typical C. utahana. The epigynum is also very similar, but is pro- 

 portionately smaller with the intermediate loop of the seminal duct on 

 each side rising only a little farther forward than the ectal 

 loop. The types differ from utahana in the spining of the 

 anterior legs. Tibia I is armed beneath with three pairs of spines 

 instead of two pairs, with two spines on the anterior face. Tibia II 

 bears beneath three spines in line toward the caudal side with a fourth 

 one paired with the most distal of these at distal end while on the 

 anterior face is but a single spine; in utahana, on the other hand, there 

 are but two spines beneath toward the caudal side with one distal spine 

 not in line with these, while there are two spines on the anterior face. 



Length, G mm. Length of cephalothorax, 2.1 mm. Length of tib. 

 + pat. I, l.S mm. ; of tib. + pat. IV, 2 mm. 



Type — M. C. Z. 469. New Mexico: San Geronimo.
