me that the spiders referred to ia the above synonyms are all of 

 the same species. 



The adult male measures from 1-1 2th to 1-1 Oth of an inch in 

 length. 



The cephalo-thorax is yellow, sometimes slightly suffused with 

 blackish towards the margins ; the ocular region is prominent 

 but not elevated, and the profile below the eyes (i.e., of the 

 clypeus) is very hollow, owing to the prominence of the ocular 

 region and of the lower margin of the clypeus ; the legs are 

 long, slender, and yellow ; the spines distinct, but not very con- 

 spicuous ; the falces rather long, divorgent, but not very strong ; 

 the palpi are similar in colour to the legs ; the radial and cubital 

 joints are short, the latter has a not very long, nor strong, black 

 bristle at the fore-extremity of the upper side, and the former 

 is the larger, considerably dilated above at its f ore-extromity, and 

 furnished on the upper side with numerous black bristles and hairs. 

 The digital joint is of moderate size, with a lobe on its outer 

 side, and a small, somewhat conical, prominence at its base on 

 the inner side. The palpal organs are prominent and complex ; 

 but though characteristic in their structure they do not present 

 any very conspicuously distinctive processes. The abdomen is 

 oviform, and considerably convex above ; its colour is dull 

 yellowish, tinged with brown, and sparingly spotted with small 

 white spots ; along the middle of the upper side is a series of 

 blackish, transverse, angular lines or bars, the first one or two 

 being incomplete at the apex, and some of them at times having 

 the extremities dilated into an irregular blotch ; the sides are 

 blackish, with two oval, orolongate, yellowish- white markings in a 

 horizontal line ; the posterior of these markings, on each side, unite 

 over the abdomen above the spinners; the under side is strongly suf- 

 fused with brownish-black. This description of the abdomen is most 

 uniformly applicable to the female, as the male has the abdominal 

 markings usually more or less obsolete ; in other respects the 

 sexes are remarkably similar ; the abdomen of the female, how- 

 ever, being much more convex abovo, and the genital pi^icess 

 characteristic,
