dark brown, with a transverso liglit marking- behind the eye.s. The 

 whole cephalothorax is thickly covered with light scales, and the 

 front half with black liairs between them. The legs and palpi are 

 light at tlie base and darker l)rown toward the tips, covered with 

 scales an<l hairs, either black or various shades of gray. The abdo- 

 men is marked with three or four ))airs of dark spots, united together 

 more or less in different spiders, the front pair usually forming a 

 single transverse mark, with a light mark in front of it. The light 

 portions of the abdomen are yellowish in the middle, and bright 

 copper-red at the sides. 



The male palpi have the femur long, the patella about as long as 

 wide, and the tibia half as long as wide. The tibial hook is large 

 and flat, tig. 5d, and lies against the tarsus, nearly half its length. 

 The tai'sus is short and Avide, and the bulb of the palpal organ flat 

 and circular.- The tube starts at the base and curves around the 

 inner side, ending in a short groove, pointing outward on the end of 

 the tarsus. Fig. 5 c.

Habrocestum peregrinum, Peckham. 



These specimens have been identified for me by Mr. Peckham. 



The female is 6™"" long, the male a little smaller ; both sexes smaller 

 than IT. splendens. The area between the eyes slopes forward and is 

 covered with short scales mixed with longer hairs, light brown in front 

 and darker behind, where it meets a white marking pointed forward in 

 the middle and curved backward and outward behind the eyes. PI. 

 XX, fig. 6. On each side of the cephalothorax is a white stripe, 

 extending from the front lateral eyes backward under the eyes, and 

 then curved upward and again downward to the end of the thorax. 

 The abdomen has three white stripes, with black between, narrower 

 and sharper in the male. The under side of the body and legs are 

 light brown, with white and black hairs. 



The legs of the third pair are very long in both sexes, and in the 

 male there is a peculiar shape to the patella, fig. 66, which is 

 flattened and widened at the distal end, where there is a stout spine 

 extending over the tibia. On the front of this flattened patella is a 

 black spot. Mr. Peckam gives an account of the use of this orna- 

 mental patella in the pairing of an allied species in " Occasional Papers 

 of the Nat. Hist. Soc. of Wisconsin, vol. i, No. 3, 1890." Peck-
