Tarsi of palpi reddish- 

 Tibis of legs of 



tibia + patella 

 (inland). The 



ventral surfaces of metatarsi and tarsi also black, 

 brown. 



Spines of legs longer relatively than in the female 

 the third and fourth pairs each with a long spine 

 at proximal end and with one distad of the middle 

 on dorsal surface. 



For structure of the palpal organ see fig. 4. 



Length of the cephalothorax, 8.5 mm.; width, 

 6 mm. 



Length of leg I, 25.3 mm.; tibia + patella, 

 8.5 mm.; metatarsus, 5.7 mm. 



Length of leg II, 22.6 mm. 



Length of leg III, 21 9 mm. 



Length of leg IV, 27 3 mm. 

 8.7 mm, J metatarsus, 7.2 mm. 



Locality. — United States 

 specimens above described are from a locality not 

 definitely known, but possibly from Arizona or 

 Southern California. Pikei would appear to dis- 

 place it on the seashore. 



Prof. Montgomery's Species. — The female of 

 Lycosa nidi/ex, above described, is seen to agree 

 with Pikei dM^fatifera in lacking spines above on 

 the tibise of the third and fourth legs, and would 

 thus go into Geolycosa, Montgomery, as Banks f>g. 4-— Palpal organ of

defines it, while the male has these tibiae armed 



above as usual, and must be separated from the female and referred to 

 Lycosa. Thus the only definite character that has been suggested for the 

 maintenance of Geolycosa as a genus is found not to be tenable, as on 

 other grounds I have elsewhere stated, and as was to be expected from its 

 nature. As the characters upon which Montgomery bases the genus 

 originally are wholly intergrading, there appears at present no reason for 

 maintaining it. iVs its author conceives it, it can be used only in an un- 

 certain way and is not natural. Carolitiensis being included in it, various 

 other forms must also logically follow, and finally all species of Lycosa. 

 Doubtless apulicE, the European species most close to Carolinensis, must 

 be included with the latter wherever placed ; but if so, the genus Taren- 

 tula, Sund., erected as long ago as 1833, ^'t''' (ipulice as the type, would 

 have to be used in case of removal from Lycosa.
