1, 4, 3, 2. Abdomen small and short, slanting from the anterior part to 

 the spinnerets. 

 Coloration: As our specimen is considerably rubbed we quote the color 

 description given by Cambridge. ' ' The cephalothorax of this very 

 pretty and distinct spider, is of a yellow brown color, with a large 

 pale patch on each side of the hinder extremity, and the ocular area 

 black, thinly clothed with short white hairs, and shining, in some 

 lights, with a strong, metallic, dark violet hue; a pale stripe densely 

 clothed with bright white squamose hairs runs tlu'ough the middle 

 of the hinder half of the ocular area to the beginning of the posterior 

 slope; there is also a spot of similar hairs on each side towards the 

 hinder part, and another on each side near the hinder part of the 

 ocular orea, just below the eyes of the third row. * * * 

 The legs are yellow, the femora and the two other basal joints 

 of the first pair being much stronger than the rest, and brown- 

 ish black on each side. This, however, is apparently not a con- 

 stant character; or at any rate it does not always exist at the first 

 coming of the spider to maturity, but probably is acquired later; for 

 in one of the examples before me the first pair are of the same color 

 as the rest, and the femora of only ordinary comparative strength, 

 and the legs themselves shorter and weaker. * * * The palpi are 

 pale yellow. * * * The falces * * * are of a brownish yel- 

 low color with a broad rather oblique dark yellow-brown longitudinal 

 stripe on the fore side. Tlie maxillce are yellow-brown, -paler at their 

 extremities. The labium is also yellow-brown, palest at the apex. 

 The sternum is * * of a pale yellow color. The abdomen is of a 

 palish yellow hue; on the fore half of the upper side a clearer yel- 

 low elongate-oblong central marking is indicated by a dark-brown 

 dentated marginal line, and terminates posteriorly with a short trans- 

 verse curved dark-brown stripe, behind which, again, are two longi- 

 tudinal curved dark-brown markings inclosing a circular area cov- 

 ered densely with udiite squamose hairs which extends forward also 

 to the transverse stripe above described. The sides are marked with 

 a few dark-brown spots and markings; and on each side of the fore 

 extremity of the oblong central marking is a large patch of white 

 squamose hair. In front, below the fore margin, are some coarse, 

 bristly, black, upturned hairs. The spinners are of a blackish hue, 

 tipped with pale yellowish. * * * There is evi- 



dently some variety in the abdominal markings of this sj)ecies, 

 since in the other example before noted the upper side of the abdo- 

 men is generally suffused with dark blackish brown, showing faintly 

 the longitudinal oblong central, yellowish marking on the fore 'part; 

 the posterior and two anterior large patches of white squamose hairS' 

 however, are even more conspicuous in this than in the other ex- 

 ample."
