546 General Notes. 
shells by the color and shape of its abdomen. The two specimens 
which I collected deceived me at first, but a few threads of silk led 
me to make the examination. The spider seemed so confident of 
its protection that it would not move when I jarred the plant, strik- 
ing it several hard blows. I pulled the spider forcibly from the 
leaf, and it did not exhibit any signs of movement until transferred 
to the cyanide bottle. The cocoons which I have found here are 
also protected by mimicry. They are essentially like those of Cyr- 
tarachne bisaccata Emert.! They are dark brown, about 12 mm. in 
diameter, and are provided on two opposite sides with stems made 
of the same colored silk, about 5 mm. in diameter. The whole 
structure, which is hung in the branches of some weed, strongly 
resembles an insect gall made on the stem of some plant. As the 
species seems to be new, I append a description. 
Cyrtarachne multilineata, n. sp. Middle eyes on a slight eleva- 
tion, forming a trapezium, the posterior a little larger and farther 
apart than the anterior. Side eyes at a distance, very close to each 
other,also on a slight elevation. Cephalothorax brownish, rising grad- 
ually from the low head to the abdomen, which partly covers it, 
not narrowed behind the eyes, convex on the sides, covered with 
minute pointed tubercles, the two dorsal elongated prominences 
ending each in two blunt points. Abdomen triangular, sides 
slightly convex, angles rounded, ventral surface deeply concave. 
Anterior one-third of abdomen hair brown mottled with the ground 
color—ecru drab—a pair of large spots of the ground color near 
the posterior edge of the brown. On the posterior part of the 
abdomen are several transverse bars of hair brown, becoming suc- 
cessively narrower and shorter toward the apex. Four of the mus- 
cular impressions very deep. Sides and posterior part of the abdo- 
men densely marked with hair, brown depressed lines, starting from 
near the centre of the ventral surface, and passing up over the dor- 
sal surface of the edge, four of those on the posterior part passing 
up nearly to the posterior pair of deep muscular impressions. On 
the ventral surface there is a rectangular spot extending from the 
spinnerets to the anterior edge, the anterior half of this brown, 
the posterior white; the depressed lines arise from the sides of this 
spot. Legs light colored. Described from two females. 
of the larger 13 mm., abdomen 15 mm. broad, 10 mm. long; 
length of the smaller 11 mm., abdomen 13 mm. broad, 9 mm. long.

NOTE ON THE TUBE-INHABITING SPIDER, Lycosa fatifera Heats 
—There seems to be a general impression that the tube-building 
Lycoside do not use their holes for such a permanent ise ol 
place as do the species of trap-door spiders. Good authorities
