480 COLEOPTERA. 



Horelophus walkeri, discovered at Reefton by Commander J. J. Walker, 

 R.N., I have not seen, but the admirable description published by M. 

 d'Orchymont enables me to state that it is abundantly distinct. 



Length, 2\ mm. ; breadth, f mm. 



Moa Basin, Canterbury. Two examples, one damaged and mounted 

 on its back, are all I have seen ; both we;;e found by Mr. T. Hall on or about 

 the 20th October, 1913. 



Group Staphylinidae.

3983. Quedius urbanus sp. nov. 



Elongate, aeneo-niger, head and thorax shining, elytra rather dull with 

 infuscate pubescence, hind-body similarly clothed but slightly iridescent ; 

 mandibles rufescent ; labrum, legs, and antennae fusco-castaneous ; the 

 terminal and basal three joints of these last, and the tarsi, more or less 

 light fusco-rufous, palpi paler. 



Head subrotundate, rather broader than long, tripunctate between the 

 front of the eyes and alongside each, bipunctate at the base. Thorax 

 finely margined at the sides and base, broader than long, widely emarginate 

 in front so that its angles, though not acute, appear prominent ; base and 

 posterior angles somewhat rounded, its sides very slightly narrowed before 

 the middle ; there are two distant pairs of punctures near the apex and 

 on the middle, a basal pair near each angle, and a more distant pair before 

 the closely punctate scutellum. Elytra medially emarginate behind, so 

 that in the middle they are nearly twice as broad as long ; their sculpture 

 close, punctiform or indefinitely granular. Hind-body more than half the 

 whole length, gently attenuate posteriorly, segments 1-5 gradually increase 

 in length, sixth narrower and rounded behind, seventh still narrower, pallid, 

 terminal styles elongate ; the sculpture and vestiture like those of the 

 elytra. 



Labrum short, medially notched, with elongate, dark setae, and pale 

 membranous appendage. Clypeus very short. Eyes more than half the 

 length of the head. Anterior tarsi widely expanded and hairy. Antennae 

 rather slender, just reaching the thoracic base. 



Although the elytral sculpture is less granular, this species should be 

 placed near 1845 in Section VIII. 



Length, 13 mm. ; breadth, 2^ mm. 



Glenhope ; 18th July, 1915. One, found by Mr. T. Hall. 



3984. Quedius iridescens sp. nov. 



Elongate, slightly convex, nigrescent ; liead and thorax glossy, sub- 

 aeneo-niger ; hind-body beautifully iridescent, its ierminal two segments 

 rufescent ; the mandibles, labrum, tarsi, and basal three joints of antennae 

 more or less reddish, remaining joints of these last dull fuscous ; legs 

 darker red, the hind pairs particularly ; elytra and hind-body with slender, 

 decumbent infuscate pubescence, and, like the head and thorax, bearing 

 many elongate upright setae. 



Head and mandibles about a third longer than thorax, nearly as broad 

 as it is, hardly at all rounded ; with two, or three, punctures alongside 

 each eye and two larger ones behind each, and a pair of basal ones. Thorax 

 slightly broader than long, the base and sides finely margmed, the former 

 curvate with obsolete angles, the latter slightly narrowed towards the some-
