ings dark reddish brown. The femora of legs one and two are 

 spotted with dark red, thickest toward the front (fig. 3J). 



The epigynum has a wide oval opening divided into two round 

 smaller ones by a wide ridge on which is a thin raised line in the 

 middle (fig. 3<^). 



The male palpus has a large complicated process on the outer side 

 at the end of which is a small black point, hooked at the end. The 

 tube of the palpal organ is wide and curved once around the end of 

 the bulb (PI. XXX, figs. 3(7, 3e), ending on the outer side. The male 

 palpus is much longer than that of vatia and more than twice as 

 large as that of aleatoria. 



The abdomen of the adult female has often gray or reddish mark- 

 ings along the sides or in the middle. 



Misumena oblonga Keys., Spinnen Americas, 1880. 

 Plate XXX, figures 4-4c. 



Male 2-5"™ long. Front legs 8'""" long and very slender. Colors, 

 in alcohol, greenish yellow on the cephalothorax and legs and white 

 on the abdomen and around the eyes, with dark red markings. The 

 front of the head is high, the distance between the upper lateral 

 eyes being twice their height, as in M. vatia, but it does not have 

 the white mark in front like that species. The eyes are all slightly 

 raised on whitish tubercles. PI. xxx, fig. 4. 



The sides of the cephalothorax are slightly darkened and around 

 its edge is a fine red line, short in some and in others extending its 

 whole length, and there are also, in one specimen, red lines across 

 the ends of the mandibles. The first and second legs have a short 

 red ring at the end of the femur and the patella. The tibia has the 

 distal half red and also a short ring at the base. The metatarsus is 

 red for three-fourths its length, and the tarsus half its lengtli. 

 There are also a few red spots on the front of the first femur and at 

 the ends of patella and tibia of fourth leg, but these spots are absent 

 in one specimen. The cephalothorax, abdomen, and femora have 

 stifi" black hairs, standing wide apart. 



The male palpi are as small as those of aleatoria, but shorter and 

 more pointed, like those of vatia. The outer process of the tibia is 

 much like that of vatia, but shorter and thicker, and the hook is 

 placed more on the outer side. The tube is longer and straighter 

 and more slender than in vatia. PI. xxx, fig. 4. 



The only female that seems to belong to this species is an imma- 

 ture specimen 4*5""^ lung. The color is pale yellow, darkened a
