long on the ni)per side, nearly covering tlie tarsus. The end has a 

 long hook bent s^idewise. PI. X, figs, li, 2c. Menge includes in this 

 genus several species with two humps on the head, but which 

 have the holes behind the eyes and otherwise appear to belong 

 with Lopliocaremim.

Plate X, figure 1. 



Qinin long. Cephalothorax dark brown. Abdomen dark gray. 

 Legs yellowish brown. Both sexes alike in size and color. The eyes 

 in the female are large and in two rows at about equal distances from 

 each other. The head of the male is much raised and the lower part 

 extended forward, Fig. 1, forming two horns. The eyes are smaller 

 than in the female. The hind middle pair is on the upper horn, the 

 front middle pair on the lower horn, and the side pairs separated far 

 from them, below the hind pair. The male palpi have the tibia 

 expanded as much as the tarsus, and a long hook with a sharp point 

 bent across the end. Fig. \b. The palpal organ is peculiar in having 

 the tube short and not coiled as in niost of the neighboring species. 

 When in use this ajipears to be supported by a strong process near 

 the end of the palpus and perhaps, also, by the tibial hook, which 

 could be brought over it by a slight revolution of the tarsus. 



I have specimens from Montreal, Canada, under leaves, in winter ; 

 Boston, Mass., on fences, in October; and Cambridge, Mass., under 

 leaves.

Same colors as cristata^ but smaller, about r5">'" long. In the 

 female the front middle eyes arc more prominent and farther from 

 the side pairs than in cristata. In the male the lower part of the 

 head carrying the front middle eyes is much as in cristata, but the 

 upper horn or hum)) is larger and lower and the eyes on the top of 

 it are farther a])art. The male palpi haVe the tibia similarly 

 expanded, but the hook is longer and wider. The tub<j of the 

 paljsal organ is short and curved.
