are 1*4 as long as the tibia. The femur o£ the fourth pair o£ legs, which is 

 suddenly raised beyond the stalk and attenuated towards the end, is 2*4 as 

 long as deep ; the tarsal joints are a little longer than the tibia. 



Measurements ? -—Leg I. : femur 0*410 (0-137) ; femur ii. 0*220 (0*122) ; 

 tibia 0-288 (0*084) ; tarsus i. 0*228 (0*065) ; tarsus ii. 0*128 (0*046) mm. 



Leg IV.: femur 0*737 (0*304), trochantin 0*228; tibia 0*562 (0*129); 

 tarsus I. 0*342 (0*088) ; tarsus ii. 0*243 (0*061) mm. 



Material. — Of this species I have examined 27 females and 3 5 males from 

 New Granada and a few from Bogota (Keys. Coll.). It has previously been 

 recorded from Venezuela. 



5. Olpium furciliferum, Balzan. 



1881. Balzan, (6) pp. 537-538, pi. 12, figs. 30-30 b. 



About this species I will only add a few remarks to Balzan^s description. 

 The femur of the palps has a " tactile "' hair dorsally at the base ; the fingers 

 have close rows of marginal teeth. The coxce are as in the preceding species. 

 The tarsus of the fourth pair of legs has a basal " tactile " hair, and the 

 arolium extends, as in the preceding species, distinctly beyond-the claws. The 

 legs are less slender than in Olp. cordimanum ; the tarsal joints of the first 

 pair of legs, of which the first is 1*3 as long as the second, are 1*3 as long as 

 the tibia ; the femur of the fourth pair of legs is twice as long as deep, and 

 the tibia is almost 1*1 as long as the tarsal joints. 



Measurements.— Leg I. : femur I. 0*296 (0*106) ; femur II. 0*152 (0*102) ; 

 tibia 0*243 (0*068) ; tarsus i. 0*182 (0*049) ; tarsus ii. 0*137 (0*038) mm. 



Leg IV. : femur 0*555 (0*277), trochantin 0*190 ; tibia 0*456 (0*122) ; 

 tarsus I. 0*243 (0*068) ; tarsus ii. 0*175 (0*050) mm. 



Of this species, which has been previously recorded from Venezuela, I have 

 examined a single male collected in St. Vincent by Mons. E. Simon. 



6. Olpium brevipes, sp. n. (Plate 9. figs. 29-33 ; cf. With, 18. fig. 13, 



p. 89.) 



?. 



Ceplialotliorax. — The anterior pair of eyes are placed on the lateral margin 

 and removed from the front margin a distance somewhat smaller than their 

 diameter. The ceplialotliorax, which is a little narrower behind than it is long, 

 is only slightly attenuated towards the eyes and then distinctly narrowing, 

 forming a short cucidlus, which has a shallow notch on the front margin 

 (cf. 18. fig. 13, p. 89). No trace of transverse sutures observed ; the skin is 

 almost smooth, somewhat polished, and with moderately long pointed hairs. 



Abdomen. — The fairly long and slender abdomen has the undivided sclerites 

 almost smooth, but not polished ; the sclerites of the two first segments are 

 almost obsolete. The tergites bear along their hindmost margin about ten 

 pointed generally long hairs ; last segment at least with "tactile" hairs.
