eyes on rather pronounced tubercles suggesting those of some species of Microneta. 

 Posterior row of eyes straight; median eyes a Httle less than their diameter 

 apart, and a little more than their diameter from the laterals. Anterior row of 

 eyes straight or scarcely recurved; median eyes less than their radius apart, 

 their diameter from the laterals. Palpal organ with a broad membranous 

 blade curving forward from base beneath the style, its edge denticulate above 

 across its distal end. Hook bent into a semicircle with a subquadrate plate 

 from its ectal side below and a spur at the caudodorsal angle of the latter as 

 shown in Fig. 20, 3. 



Length of cephalothorax 1.46 mm.; width 1.14 mm. Length of tib.-j-pat* 

 I 1.74 mm.; of tib. + pat. IV 1.85 mm. Metatarsus I of nearly same length 

 as tibia L 



Locality. — Utah : Bear Lake. One male. 



Microneta uta, sp. nov. 



Ma/c— Cephalothorax, abdomen and palpi black or nearly so. Legs 

 fulvous, in part slightly dusky. Cephalothorax conspicuously narrowed in 

 front of middle, obviously longer than broad (cir. 7: 5). Posterior row of eyes 

 straight; the median eyes slightly larger, scarcely their diameter apart. Anterior 

 eyes in a straight line; the eyes nearly equidistant with the medians smaller 

 than the laterals. Head slanting obliquely forward from posterior row of eyes 

 to anterior row, the anterior median eyes carried forward above upper part 

 of clypeus, the clypeus slanting forward, its profile straight. Tibia of palpus 

 widening distad and a little elevated above but without any distinct process. 

 Tarsal hook abruptly bent back, the distal or recurving portion long. See Fig. 

 20, 4. - 



Length 1.75 mm. Length of cephalothorax .7 mm.; width .5 mm. Length 

 of tib. + pat. I .76 mm.; of tib. + pat. IV, .86 mm.; of met. IV. 6. mm. 



Locality. — Utah: Logan Canyon. 



Diplocephalus cryptodon, sp. nov. 



Female. — Cephalothorax and legs yellow of a dilute orange tinge. Abdomen 

 dark gray. Posterior row of eyes conspicuously procurved ; median eyes less 

 than their diameter and more than their radius part, the same distance from 

 the laterals or nearly so. Anterior row of eyes straight or nearly so; medians 

 considerably smaller than the laterals, about their radius apart and scarcely 

 farther from the laterals. Clypeus in height equalling the length of the median 

 ocular area or a little lower. Median ocular area longer than wide. Upper 

 margin of furrow of chelicera armed with four teeth of which the three nearest 

 the claw are long and subequal, the fourth tooth smaller; lower margin of furrow 

 with four similarly well separated but similarly much smaller teeth. Epigynum 

 as shown in Fig. 21, 3. 



Male. — The postocular swelling is slight, scarcely or not at all rising above 

 level of eyes, the hair short and sparse, forming a median longitudinal line; 

 lateral pits conspicu(nis. Posterior row of eyes procurved; medians half their 

 longer diameter apart, nearly twice as far from the laterals.- Anterior row of 

 pyes straight; the medians much smaller than the laterals, less than their radius
