116 ON NEW SPECIES OF TASMANIAN ARANE^. 



medial mark ; dorsal band somewhat compressed from iiumeral 

 tubercles, widely dentate ; fore-third of constricted part, 

 speckled, cream colour, disj^lajs an olive-brown medial stripe, 

 traversed by three streaks ; posterior tv^o-thirds yellowish- 

 olive, mottled with olive- green ; three small impressed dots 

 arranged in a recurved line occur on verge of anterior 

 slope ; five pairs of blue-black impressed spots on constricted 

 part of band ; two fore-pairs most proDOunced, form a trape- 

 zoid narrowest in front, on the cream-coloured area ; lateral 

 margins gamboge colour, speckled with the normal red dots ; 

 inferior half mottled with olive-brown, displaying a somewhat 

 acute-crenate outline ; fore-part of ventral aspect oceupied by 

 a brown, semi-circular T:>atch, bordered on outer side with 

 yellow ; posterior part fuscous. Corpus vulvce black-brown ; 

 represents a projecting, triangular, transversely rugulose, 

 aplanate scape, more than twice as broad as long, margins 

 wide, re volute, increasing in breadth at apex ; superior 

 m.argin of corpus developed into a rather wide membraneous 

 costa, curving somewhat over the rima gentitalis, centrally 

 depressed. 



Single example. 



Epeira ohscurta, sp. nov. 



Fen. ceph. th., long, 27; broad, 2 ; facial index, 15. Abd. 

 long, 5 ; broad, 4. Legs, 1, 2, 4. 3=10, 9, 8, -3, 6 mm. 



CepJialothorax lake colour ; hairs white, tolerably long and 

 sparse ; pars cephalica convex, roundly truncated, eye-promi- 

 nence tolerably strong ; facial index exceeds lateral by one- 

 third ; mamiform elevations moderately developed ; clypeus 

 perceptibly surpasses diameter of a fore-centre eye ; pars 

 thoracica somewhat depressed, well rounded ; fovea sub-oval ; 

 normal grooves rather shallow ; contour of profile represents a 

 low arch. 



Eyes tolerably small ; posterior row straight ; median pair 

 posited obliquely on large circular, elevated fuscous spots, 

 divided by an interval equal to twice an eye's breadth and a 

 half, their space and one-third from laterals ; anterior row 

 only moderately recurved ; centrals sensibly larger than hind 

 pair, a little more distant from them than they are from each 

 other, an interval visibly shorter than the space separating 

 the hind centre eyes ; laterals rather smaller than posterior 

 median pair, divided by a space scarcely equalling their radius, 

 seated obliquely on rather low eminences. 



Falces light, dull ochreous-brown ; hairs fine, whitish ; sub- 

 conical, vertical, profile curved, first half prominent, length 

 equal to interspace between anterior lateral eyes ; as stout 

 as the pars femoralis of a fore-leg.
