228 AMERICAN SPIDERS AND THEIR SPINNINGWORK. 
Eyrs: The ocular quad (Fig. 9c) is slightly wider in front, and is longer than wides 
MF are separated by 1.7 diameter, and are larger than MR, which are separated by less than 
a diameter; the space between MF and SF about equals the space between MF; SF*are 
slightly smaller than SR, and the two eyes are scarcely contingent; SR placed well to the 
side of SF, making with the front row of eyes a continuous curve. The space between MR 
and SR is at least three times greater than between MR; front eye row recurved; rear row 
slightly procurved; MF are placed close to the margin of the clypeus, and project oyer it. 
Leas: 1, 4, 8, 2; the color in some specimens is dark green, with strong blackish 
brown markings at tips of joints, which embrace half or more of the length of the femora ; 
in others these annular bands are less decided, leaving the legs, like the cephalothorax and 
abdomen, prominently green; they are rather sparingly armed with long brown spines and 
with stout short bristles on the two terminal joints. The mandibles are conical, on the 
same plane with the face, by which they are overhung. ‘ 
Aspomen: A long oval, widest in front; color green, with a lighter band passing from 
the base to the apex, in some individuals marked on the edges of the dorsum by scalloped 
bands of light brownish hue. A median line of brown passes along the entire dorsum, with 
curved radiating lines on either side. The dorsum is rounded at the base, curved down- 
ward in the middle, and terminates in two decided points, separated by a deep triangular 
bifurcation or notch, giving the apex the form of a fish’s tail. Four conical tubercles are 
placed on the base of the dorsum, two at the shoulders and two farther back more widely 
separated than the former. The yenter is a brownish patch, with median spots of green, 
and a green marginal band between spinnerets and epigynum. The spinnerets are placed 
nearly. midway of the abdomen, caused by the greatly projecting caudal part; they are 
surrounded by a broad white band, which extends along the venter as far as the epigynum, 
which is a subtriangular flap, without prolonged scapus. (Fig. 9b.) 
Mate: The only male which I have is immature, apparently lacking one moult of 
maturity. It is about 4.5 mm. in length, and resembles the female. (Tig. 10.) 
Distrievrion: I found this species on Merritt's Island, Indian River, Florida, nested in 
great numbers on the porch of a rustic hotel. Its general habits, snare, and method of pre- 
serving its cocoons resemble that of Cyclosa conica and C. caudata. 
No. 80. Cyclosa Thorelli, new species. Plate XIX, Fig. 11. 
Fremate: Not quite mature. Total length, 11 mm.; abdomen, 8 mm. long, 2 wide; 
cephalothorax, 38.5 mm. long, 1.7 mm. wide. 
Crpnatornorax: A long oval, truncated and scalloped at the base, high and peaked ; 
the fosse a deep slit along the summit of the corselet, which decidedly slopes both back- 
ward and forward; the head much depressed; almost as wide at the face as at the cephalic 
suture, which is indistinct. Color dark yellowish brown, with yellowish irregular streakings 
upon summit of corselet and base of caput. Both corselet and caput sparsely furnished 
with short, white, bristlelike hairs, which continue around the face. The sternum (Fig. 11b) 
shield shaped, with scalloped edges pointed at the apex; decidedly longer than wide; the 
sternal cones well marked; rounded in the middle; color yellowish brown. The labium is 
triangular; not more than one-third the height of the maxille, which are rounded, of a 
distinct Epeiroid type, but slightly longer than wide. ; 
Leas: 1, 4, 2, 3; stout; not heavily armored, although in the specimen under descrip- 
tion the spines and bristles have been lost in the alcohol. Color yellowish, without annuli; 
but with traces of longitudinal stripes on some of the joints. The mandibles are conical ; 
quite divergent at the tips, and sloping backward a little toward the sternum. 
Eyes: Ocular quad (Fig. 10c) longer than wide, and the front slightly longer than the 
rear; MF are black, and separated by at least 2.5 times their diameter; and are smaller 
than MR, which are amber color, and separated by about 1.5 their diameter. The quad is 
placed upon a smooth rounded prominence. The side eyes are distinctly separated, but 
approximated ; SF larger than SR; the latter placed well to the side; the two upon a slight 
tubercle. SR are widely separated from MR by at least twice the area of the latter; MI
