with deep brown-pink ; tibiae and metatarsi of second legs suf- 

 fused with red-chestnut ; femora of two first pairs have four 

 spines, 1, 1, 2 ; hind pairs, 1, 1, 3 ; tibiae of first, 2, 2, 2 beneath, 

 1 side spine inner aspect ; tibiae of second, 2, 2, 2, side spines 2 ; 

 metatarsal joints, 2, 2 ; thighs of two hind-pairs, 1, 1, 3 ; tibial 

 joints, 8 somewhat irregular spines ; metatarsi, 6, three of 

 which form a ring; hairs somewhat sparse, short, yellow, 

 adpressed ; black hairs more or less erect ; tarsal claws, first 

 pair, outer, 1 strong tooth ; inner, 15 short close teeth ; claw- 

 tuft well developed. 



Palpi lake-ochreous, stained with olive-green ; moderately 

 furnished with dusky hairs ; pars humeralis perceptibly com- 

 pressed, incrassated forwards ; in length exceeds the two 

 following joints together ; cubital joint moderately dilated, 

 one-third longer than penultimate article ; pars radialis pro- 

 duced on outer side into a tolerably long, black process, di- 

 rected forwards, inward-curved, basal half broad, fore-half 

 rapidly compressed ; lamina elongate - ovate ; fairly well 

 haired ; genital bulb ovate, moderately developed, rugulose ; 

 exhibits on outer side of anterior half a large, subtriangular 

 indentation, apex directed forwards, bounded, except across 

 base, by a turgid, reddish costa ; viewed from outer side, the 

 costal ridge is plainly prolonged round base of bulbus ; inner 

 margin of bulb bordered by a somewhat membranous, red- 

 dish costa, which reaches to apex ; projecting from the latter 

 part is a short, black process, resembling a stout, broken bristle. 



Abdomen elongate-ovate in outline, subdepressed ; hairs 

 black and yellow, thinly interspersed. Folium occupies dorsal 

 area, light olive-brown, on its fore-third appears a large red- 

 dish spot, which without any determinate limits gradually 

 fades into the ground-colour ; a series of 6 more or less 

 acute brown chevrons, decreasing in size, extends from the 

 above-mentioned spot to spinners ; lateral margins longi- 

 tudinally wrinkled ; portion of the upper series has a deep 

 olive-green colour, and forms a border to folium. Ventral 

 region yellow-brown ; shield defined by an olive-green border. 



This rather handsome Attus, which was captured near 

 Wellington, I have much pleasure in naming after Mr. T. Kirk, 

 F.L.S.

Ccphalothorax dark mahogany-colour, dorsal area mostly 

 occupied by a reddish-mahogany, lanciform figure ; sparingly
