tinlque, wliicli Walckenaer referred, though no doubt erro- 

 neously, to Mygaie BloJidii, a species hitherto known only 

 with certainty from Cayenne (Ins. Apt. i. p. 210, 1837). 



Acanthoscurria tarda^ sp. n. 



? . — Nearly allied to A. Brochlehursti^ F. Cambridge 

 (P. Z. S. 1896, p. 739, pL xxxiv. fig. 18), from Para, but 

 differing in the characters pointed out in the diagnosis as well 

 as in having shorter legs, and the Avhite stripes at the ends of 

 the leg-segments less distinct. 



Carapace as long as patella and tibia 4-^ the protarsus of 

 the fourth leg and as protarsus and tarsus of that leg, and con- 

 siderably longer than patella and tibia of first leg. 



Eyes of anterior line widely separated, the medians larger 

 than the laterals, separated by a space exceeding their 

 diameter and by about a diameter from the laterals ; poste- 

 rior medians much closer to the posterior laterals than to the 

 anterior medians; space between the two laterals almost or 

 quite equal to the long diameter of the anterior lateral. 



Measurements in millimetres. — Total length 62; length of 

 carapace 2Q, w idth 23 ; length from fovea to anterior border 

 19 ; length of first leg 63, second 58, third bo, fourth 66" 5 ; 

 patella + tibia of first 23*5, of fourth 21*5 ; protarsus of 

 fourth 17-3. 



Log. Rio Teffe, on the Amazons [Dr. Bach). 



A. ferina, Simon (Ann. Soc. Ent. Fr. 1892, p. 282), is 

 based upon a male specimen also from Teffe ; but the differ- 

 ence in size and situation of the eyes between that specimen 

 and the type of A. tarda is too great to permit one to suppose 

 that they are sexes of the same species. According to Simon, 

 the eyes of the anterior line are large, subequal, and narrowly 

 separated, the posterior medians are narrowly separated from 

 the anterior medians, and the two laterals are very narrowly 

 separated from each other. 



Acanthoscurria suina, sp. n. 



?. — Colour. Hairy clothing a tolerably uniform yellow- 

 brown, the legs indistinctly banded longitudinally and witli 

 narrow pale transverse bands at the distal ends of the segments. 

 Carapace longer than patella and tibia of first or fourth, 

 as long as protarsus and tarsus of fourth leg, almost as long as 

 the three distal palpal segments, almost as long as femur and 

 patella of fourth leg, but scarcely exceeding femur and half 

 the patella of first, distance from fovea to anterior border 

 exceeding patella and tibia of palp and protarsus of fourth leg ;
