DESCRIPTION OF GENERA AND SPECIES. 225 
diameter; the distance between MF and SF is a little greater than the area of MF; lateral 
eyes contingent, on a small tubercle, and are about as large as MR. Front eye row 
decidedly recurved, rear row slightly recuryed or aligned, and longer; the clypeus projects 
over the mandibles, and is scarcely the width of the diameter of MF. 
Lunas: 1, 2=4, 3, as follows: 4.6, 4.1, 4.1, 28 mm.; color light yellow, with narrow, dark, 
apical annuli, somewhat wider on femora; palps colored and marked as legs, and mandibles 
retreating ; somewhat shorter than the patella, and not quite as thick as femur-I. % 
Aspomen: A long ovate, narrowed at the apex into a taillike termination, directed 
more or less upward, and extending beyond the spinnerets; it is longer than broad, highly 
arched on the dorsum, which has two shoulder humps. (Fig. 5d.) The field is brown or 
yellow; the sides are marked with a few blackish stripes; the dorsal” pattern somewhat 
resembles that of C. conica, being an irregular blackish arrow shaped patch, connected by a 
narrow band to an irregular rectangular apical patch of like color; the caudal part is yel- 
lowish, with blackish borders. The venter has a broad black band which surrounds the spin- 
nerets, bearing white spots at the base; the epigynum (Fig. 5e) has a well marked scapus 
of nearly equal width throughout, but obtusely triangular at the tip; the portule are open 
and rounded, the atriolum arched, and has several small white spots of color on each side. 
Matm: Fig. 6, 6a, 6b. Total length, 3 mm.; cephalothorax1.5 mm. long, middle width 
1.1 mm., front width 0.5 mm.; abdomen, 1.5 mm. long, 1.2 mm. broad; cephalothorax a 
little longer than femur-I, not quite one-third longer than broad, in front not quite half as 
broad as in the middle; dorsally highly arched. The face at the eye space projects con- 
siderably over the clypeus, which is rather high; eyes grouped as in the female; mouth 
parts and sternum dark brown, the latter sometimes with traces of yellow spots. The legs 
have distinct spines on all joints; tibia-II has no special thickening or clasping spines; the 
coxee are without tubercles; the distal joints are of darker color; the order of length is 
1, 2, 4, 3, as follows: 3.9, 3.3, 3.2, 2.1 mm. The abdomen is but little longer than broad, is 
dewetly highly arched, rounded at both ends, and apparently destitute of the caudal pro- 
jection which marks the female; spinnerets distal; color brownish yellow or gray, with a 
broad scalloped longitudinal band, and two white spots on the basal half; the yenter black, 
with two round white spots on each side close to the spinnerets. The palpal digit is 
marked as at Fig. 6b. 
Disrrisurion; I have collected this interesting spider from, Canada and the Northern 
New England States, southward along the Atlantic Coast as far as Florida, as well as in 
Ohio and some of the Western States. Professor Peckham sends it from Wisconsin. Dr. 
Marx reports it in Louisiana and Alabama; Dr. Blaisdell sends it from California. It is 
probably distributed throughout the greater portion of the United States. Its habits are 
fully given in Vols. I., IT.

+Emerton probably refers in his description to this species, at least his drawing shows no shoulder 
humps; but he erroneously confounds it with C. turbinata.
