ARANEAE— HOGG. 



167 



longitudinal area. On both surfaces is fine down-lying yellow hair and upstanding- 

 brown- and yellow bristles. The eyes of the median quadrilateral are equal in size, the 

 rear pair their diameter apart, the front pair one and a half diameters apart and the 

 same distance from the rear ones. The abdomen is globular, without shoulder-humps, 

 slightly longer than broad. The epigyne has a moderately long upstanding stylus 

 bent over at the distal end, transversely corrugated and narrowine: from the base, 

 where it springs from a circular plaque in which are embedded long brown convex 

 chitinous lobes at the sides and base.

The male is coloured like the female. 



There are one male and a number of females, of which only three females are 

 fully grown. 



This species is near the very variable Araneus anasterus, Walck. (Ins. Apt. II, 

 p. 33. McCook, Amer. Spiders, III, p. 172, PL VIII, figs. 1, 2), common in Central 

 America and North and South of the same, which in its epigyne it somewhat resembles. 

 In this, however, the scape distinctly curls over at the apex, and the chitinous lobes on 

 the base are more prominent and separate. The cephalothorax and legs are longer by 

 one half, and the cephalic part of the cephalothorax bears a dark horseshoe mark, the 

 sides of which reach to the cejjhalic fovea, not apparent in the other species. 



These points serve to distinguish it from the above-named species of many 

 synonyms. M. Simon has made for it a new genus, Eustala {loc. clt. p. 295), seemingly 

 on somewhat slight grounds.
