200 THE CANADIAN ENTOMOLOGIST 



Catabrithorax ceuthus, sp. nov. 



Male. — Cephalothorax and sternum dusky, almost black, the eye region 

 solid black, the black protruding in a rounded spot on upper median part of 

 clypeus. Legs fulvous, slightly smoky. Abdomen dark grey. Cephalothorax 

 of moderate width; head elevated, sides slanting, eye region protruding above 

 clypeus. Sternum rather narrow in comparison with that of clypiellus, con- 

 spicuously convex, strongly narrowing from the anterior and caudad, sides but 

 moderately convex, narrowly produced between posterior coxae. Labium 

 anteriorly weakly convex, narrowing distad. Anterior row of eyes very slightly 

 procurved; median eyes smaller than the laterals, very close together, being 

 less than their radius apart, farther from the laterals. Area of median eyes 

 much narrower in front than behind, fully as wide as long. Posterior row of 

 eyes weakly procurved; eyes equal; median eyes about their radius apart, an 

 equal or scarcely greater distance from the laterals. Clypeus equalling or 

 slightly lower than the length of area of median eyes (ratio about 7:8). Tibia 

 of male palpus with an uncate apophysis above, the hook turning outwards and 

 then distad at tip as in clypiellus. Structure of palpal organ very similar to 

 that of clypiellus, as shown in Fig. 22, 1, 2 and 3. 



Length of cephalothorax .75 mm.; width .58 mm. Length of tib. + pat. I 

 equal to width of cephalothorax or very slightly longer (.Q mm.). Length of 

 tib. + pat. IV .65 mm. 



Locality. — Utah : Bear Lake. One male. 



Separable at once from the preceding specie^ by its much higher clypeus, 

 etc. It is a darker species. 



Clubionid^. 



Anyphaena intermontana, sp. nov. 



Fewa/g.— Cephalothorax and legs pale, of a weakly greenish tinge, the legs 

 not at all annulate. Abdomen also pale, the dorsum or side with numerous 

 longitudinal spots or streaks of dark, arid the middorsal region behind with in- 

 distinct and more or less broken dark chevrons. Anterior row of eyes straight 

 or slightly recurved; median eyes smaller than the laterals, about their radius 

 apart, less than half as far from the laterals. Heiight of clypeus but little more 

 tha;i equalling the radjus of an anterior median eye. Posterior row of eyes a 

 little procurved; eyes subequal; median eyes a little more than their diameter 

 apart, about their diameter from the laterals. Tibia I armed beneath with a 

 subbasal and a submedian pair of spines, the first overlapping the bases of the 

 second; a single spine on anterior face. Tibia II with a single subbasal spine 

 and a pair of submedian spines, none at distal end. 



Epigynum as shown in Fig. 22, 6. 



Length 5.8 mm. Length of cephalothorax 2.6 mm. Length of tib. + pat. I 

 2.75 mm. 



Locality.— Utah: Mill Creek. 



In the form of epigynum suggesting A. pacifica (Banks), known from the 

 State of Washington, though this is proportionately shorter and is broader 

 anteriorly, with the median channel less elongate, etc. It is readily separable
