Lophocarenum quadricristatum, new. 



Plate XIII, figure 3. 



This is a small species, 1-5"'"' long, and dull colored. The head has 

 a peculiar hump extending back nearly to the middle of the thorax. 

 •Figs. 3a, ?>h. The middle of this hump is occupied by four clusters of 

 flat bristles, and the hind eyes are crowded back over the holes in 

 the side ol the head. The side eyes are larger than the others, and 

 the front ])air of these larger than the hind ones. On the male palpi 

 the tibial hook is turned toward the side. Fig. Sc. The palpal organ 

 has a long tube as in Cornicularia. 



One male, IVom Mt. Washington, above trees. This species is 

 very near Wulckenoira diceras Camb., and may prove to be the saine 

 species. 



Liophocarenum, longitarsus, new. 



Plate XIII, figure 4. 



Length 1'5""", Cephalothorax dark reddish brown. Legs orange- 

 brown. Abdomen gray. The head of the male is wide and not 

 much elevated, and there is hardly a trace of a hump. The holes are 

 just behind the eyes and the dark brown conical cavities extending 

 from them toward the middle of the head can be seen through the 

 skin. The absence of a hump leaves the eyes nearer together than in 

 most species. The mandibles are wide at the tip and have the tooth 

 near the inner angles longer than the others. Fig. 45. The tibia of 

 the male palpus has the front edge hard and finely toothed and a 

 large tooth on the inner corner. The tarsal hook is large and sickle- 

 shaped, with three stiflT hairs in the bend. The tarsus is long, and so 

 is the palpal organ. The tube is slender and long enough to go 

 around the end of the palpus. 



One male, White Mountains, near Mt. Washington.

 the head. Legs ligiit yellow. Abdomen yellowish gray. The hum}) 

 of the male is farther back than in most species, and has a deep groove 

 on each side. The holes in the head are just back of the lateral eyes. 

 Fig. 5. Seen from in front the head is about as high as wide, and 

 has the shape of a triangle with rounded corners. Tiie tibia of the 

 male palpus is short and has a short hook turned inward. The tube
