Zool.— Vol. I.J BANKS— MEXICAN ARACHNWA. 223 



One female ; Cape Region. By the plate on mandibles 

 it goes in the section Gnaphosas, but it scarcely agrees 

 with any genus in that section, differing in the nearly 

 straight posterior eye-row and in the A. S. E., larger than 

 the A. M. E. ; it has not the appearance of a Gnapkosa . 



CLUBIONID^E. 



53. Anyphaena futilis, sp. nov. 



Plate XIII, Fig. 31. 



Length 9 7 mm., S 5 mm. Cephalothorax yellowish, with indications of 

 a darker stripe each side; eyes on black spots; mandibles dark red-brown; 

 sternum and legs pale yellowish, little darker at tips and a band on the tip of 

 hind tibia; abdomen yellowish, with two brownish stripes above, converging 

 at the tip. Cephalothorax short and broad; posterior eye-row procurved; 

 P. M. E. once and a half their diameter apart, rather closer to the equal P. 

 S. E. ; anterior row shorter, nearly straight, not much smaller than the pos- 

 terior eyes; A. M. E. less than their diameter apart, closer to the nearly equal 

 A. S. E.; mandibles long, strongly porrect, slightly divergent; sternum nar- 

 rowly oval. Legs rather long with many spines, none above on tibia I; tibia 

 plus patella I about equal to the same joints of leg IV; metatarsus IV, how- 

 ever, much longer than that of I in the $ , in <5 shorter. Abdomen nearly 

 twice as long as broad, furrow much nearer to epigynum than to spinnerets. 

 Epigynum shows a large cavity, much broader than long, bordered by red. 

 The $ palpus has the tibia twice as long as broad, with a long, slender, black 

 projection on the outer tip; the tube is long and slender, the point lying in a 

 furrow near the tip of the tarsus; a long, slender piece curved around the 

 palpal organ, and a pale transverse area at base. 



Two specimens and young; San Jose del Cabo and 

 Sierra San Lazaro. 



54. Gayenna orizaba, sp. nov. 



Plate XIII, Fig. 37. 



Length $ 7 mm. Cephalothorax, mandibles, and legs yellowish, eyes on 

 black spots; sternum pale; abdomen pale with many fuscous dots, rather 

 more numerous behind. Cephalothorax short; the posterior eye-row straight 

 or slightly procurved; P. M. E. much more than their diameter apart, hardly 

 as far from the equal P. S. E.; anterior eyes smaller, close together; A. M. E. 

 smaller than A. S. E. ; mandibles vertical; sternum oval. Legs short, all 

 spined; tibia plus patella I plainly longer than those joints of leg IV. Abdo- 

 men large, once and a half longer than broad, furrow nearer to the spinnerets 

 than to the epigynum. Epigynum shows two small holes about their diameter
