Leiobunum calcar Wood. 



Female. — Length, 7.4 mm. ; width, 4 mm. 



Dorsum mottled yellow and brown with the brown central marking distinct in 

 front and darker in spots along the edge. Back of the eye tubercle the marking covers 

 about one half the width of the cephalothorax. It narrows to the second abdominal 

 segment, and then gradually expands posteriorly at the same time becoming more 

 indistinct. Abdomen marked beneath with gray brown transverse bands separated by 

 bands of light gray. Coxae darker than in the male ; legs lighter. Chelicerse uni- 

 form grayish yellow except the tips of the claws, which are black. 



Trochanter of palpus brownish yellow, patella and tibia darker, tarsus much 

 lighter ; femur armed below with a row of short tubercles, slightly more distinct at 

 the place corresponding to that occupied by the process in the male. Patella enlarged 

 distally on the inside and thickly clothed with fine stiff hairs ; dorsal and lateral sur- 

 face armed with scattered blunt tubercles. Tibia armed below with a row of blunt 

 tubercles. Tarsus without tubercles, but clothed with fine white appressed hairs and 

 black erect setae. 



Wood (Comm. Essex Inst., VI, p. 27) described a female Pha- 

 langid which he doubtfully considered the female of this species. 

 Weed (Am. Nat., XXI, p. 935 ; Bull. 111. St. Lab. Nat. Hist., Ill, p. 

 90 ; Proc. U. S. Nat. Mus., XVI, p. 554) has expressed a doubt as to 

 the generic position of this species owing to the presence of a process 

 on the femur of the palpus of the male. 



A pair of this species in coitu was collected by Prof. J. H. Com- 

 stock at Taughannock Falls, N. Y., August 21, 1902. 



I wish to thank Professor Comstock for the privilege of using 

 material in the Cornell University collections and for many valuable 

 suggestions in the preparation of this paper.
