three times as far from the laterals. The clypeus ob\'ioush- more 

 protuberant than in female, as usual. Tibia of palpus with anterior 

 end extended into a thin, cup-like plate embracing the base of the tarsus 

 like a calvx and bearing a slender chitinous process from below its 

 distal end' See Plate XVIII, Fig. 6. 



Length of male, 2.S rrm. Length of cephalothorax, 1.2 mm.; 

 width, .9 mm. Length of tib. + pat. I, 1 mm.; of tib. + pat. IV,

Type— M. C. Z. 440. Utah: Chalk Creek.

Posterior row of eyes a little procurved; the median eyes farther 

 from each other than from the laterals. Anterior row of eyes slightly 

 procurved; eyes close together, the medians from a decidedly smaller 

 to nearly as large as the laterals; eyes equidistant or with the medians 

 nearer to each other than to the laterals. Area of median eyes trapezi- 

 fonn, much wider behind than in front, from a little longer than wade to 

 wider than long (some males). Clypeus as high as eye area. Thoracic 

 stria obscure. Pars cephalica in male rising behind the eye area; 

 piligerous in a median longitudinal stripe, with a brush of longer setae 

 just behind the eyes which may or may not be elevated on a distinct 

 process, one hair of this brush typically stouter, more spinifonn than the 

 others. Sternum broad, extending between posterior coxae. Male 

 palpus with patella not enlarged; tibia prolonged in an elongate lobe 

 of ordinary texture along basal part of ectal side of the tarsus. Legs 

 long and slender, anterior tarsi shorter than metatarsi, and metatarsi 

 shorter than tibiae. 



Genotype — W. drassoides (Emerton). 



In addition to the genotype,, originally described under 

 Bolyphantes and also later referred to Sphecozone, the ne\v form 

 described below and apparently also Bolyphantes pacificus 

 Banks, later referred to Nematogmus, belong in this genus. 

 The genus differs from Nematogmus in having the posterior 

 median eyes farther from each other than from the laterals 

 with the row at most but gently procurved, in its longer legs, in 

 lacking postocular impressions in the male, in the form of the 

 tibia of the male palpus and in not having the tarsus of the 

 latter deeply bifid at the apex. From Sphecozone the genus 

 differs, e. g., in having the median eyes of the posterior row 

 farther from each other than from the laterals, in not having 

 them borne upon the frontal lobe sometimes present in the male, 

 in lacking the notably long pedicle to the abdomen, and in the 

 form of the male palpus. I have taken the genotype, IF. 

 drassoides, originally described from Mt. Carmel, in Con- 

 necticut and until now not since recorded from elsewhere, also 

 in the Uintah Mts., of Utah, at an elevation of 7,."U0 ft.
