on fore-slope without any determinate limits, fades away into 

 ground colour; anterior border of humps and posterior 

 border of fore-patches blackish, somewhat sinuating, curve 

 round the creamy-brown humeral tubercles ; resolved behind 

 into conspicuous, indigo-coloured, lunulate marks curving 

 upwards round apex of the semi-oval area ; latter and 

 impressed spots on posterior region reddish. Vulva repre- 

 sents a narrow, transverse, brownish depression, projecting — 

 over the rima genitalis, a moderately deep, cup-shaped,, 

 yellowish process. 



Single example. A.M. 



Celaenia tumidosa, sp. nov. 



Femina. — Ceph. th., long, 6 ; wide, 6 - 8. Abd. long, 10'2 ;. 

 wide, 15; deep, 10. Legs, 1—2, 4, 3 = 23, 14, 12, mm. 



CepJialotlwrax light mahogany-brown, passing into pale> 

 yellow-brown on margins, olive tinge ; somewhat suffused 

 and speckled with olive-brown ; numerous papillas projecting 

 short, black hairs, chiefly in rows ; cephalic part somewhat 

 aplanate, sides abrupt; produced forwards and moderately 

 upwards into a strong sub-conical projection; mamiform 

 eminences well-developed ; clypeus retreating, height visibly 

 surpasses interval between a fore-median eye and the lateral 

 next to it; thoracic region — viewed laterally, conoid, margin 

 of hind-slope displays six rather deep indentations, bisected 

 fovea intersects central pair ; radial striae well-defined, short ; 

 caput grooves represent deep angular indentations at junction 

 with thorax, shallow forwards ; contour of profile rises from 

 thoracic junction at an angle of 30deg., inclined at about the 

 same angle to base of the obtuse-conical mamiform promi- 

 nences, bends slightly upwards to hind row of eyes. 



TSyes rather small ; fore-centrals about one-third larger 

 and fore-laterals one-third smaller than hind-median pair ;. 

 posterior lateral eyes visibly smaller than anterior pair; 

 posterior row recurved, line through centrals intersects side- 

 eyes ; anterior row recurved, curvature stronger than 

 posterior ; fore-centrals seated on prominence, enclose conical 

 apex ; hind-pair rather more distant from each other than are 

 the fore-pair, interval between latter pair visibly surpasses 

 the space separating them from posterior centrals, which are 

 posited on small discoid tubercles ; fore and hind-centre eyes 

 divided from laterals by an interval perceptibly exceeding 

 space between fore-centrals ; side eyes seated obliquely on 

 tolerably strong elevations ; three-fourths diameter of a 

 posterior eye apart. 



Legs green-tinged straw-colour, markings coffee-brown ;, 

 second half of femoral joints dark ; first half of anterior pair 

 splashed ; patellar uniform brown, more or less broken and
