Sternum chocolate-brown ; broad-cordate, eminences op- 

 posite coxae. 



Abdomen elongate-oval ; sparsely clothed %vith fine hairs ; 

 dorsal figure lightish-brown, clouded with olive-brown, margins 

 black-brown ; flecks dull gi-eenish-yellow or metallic ; fore- 

 third somewhat oval, margins undulating ; posteriorly con- 

 stricted to nearly one-half its greatest breadth ; constricted 

 part displays two pairs of angular projections, fore-pair short, 

 obtuse, hind pair acute, prolonged ; lateral margins olive- 

 brown, oblique dark-brown streak on basal end ; flecks dull 

 greenish-yellow with slight metallic reflections ; border of 

 creamy-coloured flecks round margin of dorsal figure ; ventral 

 surface brownish. Corpiis vulvce mahogany-brown; semi-oval 

 projection, slightly convex, large, about as deep as broad 

 across at base. 



Examples of this species, especially the males, were not 

 uncommon amongst the damp vegetation about the water- 

 courses up the Waiorongomai Gorge, Te Aroha. Individually 

 they differed somewhat in coloration and markings. A. T. U. 



Fam. THEEIDIID^. 

 Gen. Theridium, Walck. 



Titer idium zehrinia, sp. nov. 



Female. — Ceph.-th., long, 2. Abd., long, 3-5. Legs, 1, 4, 

 2, 3 = 13-1, 13, 11-5, 5 mm. 



Cephalotliorax, facial space and median surface >ellow- 

 brown, sides and oblong figure extending from fovea to pos- 

 terior row of eyes olive -brown; glabrous; oval, lateral 

 constriction forwards slight ; pars cephalica flatly convex, 

 roundly truncated, lateral index short ; pars thoracica de- 

 pressed ; indentation transverse, normal grooves moderately 

 defined ; contour of profile represents two low curves ; chjpcns 

 convex, indentation below eyes, projects forwards, depth 

 rather exceeds one-half facial space. 



Eijes of moderate and about equal size, on dark rings ; 

 posterior row slightly recurved : centrals rather further from 

 each other than they are from laterals of same row ; anterior 

 row recurved, median pair separated from one another by an 

 interval perceptibly exceeding an eye's diameter ; less than 

 that space from side-eyes, and more than their breadth from 

 j)osterior centrals ; laterals have the pearl-grey lustre of hind 

 median eyes, posited obliquely on low tubercular eminences, 

 nearly their diameter apart. 



Le(js light yellow-brown, patellae light-brown ; annuli at 

 articulation of all joints have a similar hue ; rings more pro- 

 nounced at extremity of tibiae ; armature, sparse fine hairs.
