262 AMERICAN SPIDERS AND THEIR SPINNINGWORK. 
Georgia. It is probably found in all parts of the United States and Canada. It loves the 
neighborhood of streams, and stretches its horizontal snare above the water. I have found 
them covering the plants around the base of a roaring waterfall. 
No. 108. Tetragnatha Banksi, new species. Plate XXIV, Fig. 6; Pl. XXVIII, 4. 
Matz: Total length, 6 mm., including the mandibles, 7.6 mm.; abdomen, 4 mm. long, 
1 mm. wide; cephalothorax, 2 mm. long, 1 mm. wide; general colors for the fore part, uni- 
form yellow, on the abdomen mottled with black. 
CrrHaLoTtHorax: A long oval, widest in front; the fosse a deep indentation upon the 
summit of the corselet; corselet grooves indistinct; cephalothorax suture sufficiently marked. 
Color yellow, tipped with brown, and sparsely covered with gray pubescence; caput ele- 
vated above the corselet and of like color; face wide, with pubescence in the ocular area. 
Srernum: Arrow shaped, longer than wide, receding from the apex, raised in the 
middle where it is flattened; color dull yellow, with scant pubescence. Labium long, wide 
at the base, subtriangular at the tip; less than half the width of the maxille, which are 
long, club shaped, of nearly equal width throughout, roundly truncate at tips, which point 
outwards. 
Eyes: Ocular quad widest behind, the length about equal to the width; MF on a 
rounded elevation and separated by about 1.8 diameter, and smaller than MR, which are 
separated by about two diameters. SF decidedly smaller than SR, and the two more 
closely approximated than the middle group; the space between SF and MF is about twice 
the distance between MF; between MR and SR a little greater than between MR. Front 
row slightly recurved, rear row aligned or nearly so; clypeus wide, equal at least to twice 
the diameter MF. 
Leas: 1, 2, 4, 3; leg-II being but slightly longer than leg-III; thin, sparsely provided 
with dark brown spines and feeble bristles; color yellow. Leg-I measures from 20.5 to 
22 mm. The mandibles are about 2 mm. long, concaye externally, slightly increased in 
width towards the apex; the fang evenly curved externally, but underneath slightly undu- 
late, and extending below the tips of the maxillee when folded; about six to eight teeth of 
nearly equal length; on the inner and upper surface a strong, long, slightly bifid spur. The 
radial joint of the palp is about 1.5 times the length of the cubital joint, and is provided 
with a slight curyed projection, which distinguishes it from the males of other indigenous 
species of Tetragnatha. 
Aspomen: The abdomen is cylindrical, about four times longer than wide, somewhat 
narrowing towards the distal spinners. An indistinct folium marks the dorsal surface, 
which is reticulated and flanked on either side by a band of brownish color. I have what 
I regard as the female of this species, but am not certain as to the identity, and therefore 
give no detailed description. In general form and color it resembles the male. 
Disrrizution: I have several specimens of this species, which I have dedicated to Mr. 
Nathan Banks, from Florida, and one from Wisconsin. This would indicate a general dis- 
tribution throughout the United States.
