Areoncus littoralis. new 



1.5 mm. long, pale and dull in color, without markings except a 

 trace of transverse light spots on the gray of the abdomen. The 

 cephalothorax is wide in front and the head is slightly elevated and 

 extended forward in a rounded point beyond the mandibles. The 

 eyes are spread wide apart, the lateral pairs nearly to the sides of the 

 head. The upper middle eyes are their diameter apart. The front 

 middle pair are the smallest and almost touch each other on the front 

 of the head. Below the eyes the front of the head is covered with 

 scattered hairs that turn upward. The male palpi are short, the 

 tarsus rounded and the tibia widened a little at the end with only 

 a short flat tooth on the upper side. Figs. 6, 6 a, 6b. PI. I.

Lophocarenum hartlandianum. new 



1.5 mm. long, pale brown, the males generally darker than females. 

 Head of male slightly elevated with grooves at the sides distinctly 

 marked by black lines. Just behind the eyes are pits extending 

 inward from the grooves and distinctly visible through the skin as 

 dark markings. The dark lines over the grooves extend forward and 

 unite with black spots behind the lateral pairs of eyes. The male 

 palpi are large and conspicuous, the tibia is twice as long as the patella 

 and is widened at the end where it extends over the tarsus. On the 

 upper side toward the outer corner are two teeth, the inner one recur- 

 \'ed and sharp. The tarsus is folded over in a sharp ridge and is 

 narrowed toward the end as seen from above Fig. 7 a. The tube of 

 the palpal organ is long and slender, and makes two turns under the 

 tarsus, resting against the ridge on the upper side of the tarsus with 

 the tip between the two teeth on the tibia. Fig. 7. PI. L 



The female has no peculiar markings. The epigynum shows a 

 distinct middle lobe with the spermathecae showing through the skin 

 at each side of it.
