ERIRHINIDAE. 563 



joints 3-7 transverse ; club suboblong-oval, quadriarticulate, terminal joint 

 very small. 



Legs stout, tibiae distinctly mucronate, the two hind pairs flexuous. 



E. celniisiae (3928) is larger, more glossy, and differs in colour. The 

 elytral punctation is rather finer, not as close, and becomes somewhat vague 

 behind ; in E. altivcigans it is distinct from base to apex, and the apices 

 are not individually rounded. Both species structurally are like 2917, 

 E. spadiceus (Ann. Mag. Nat. Hist., ser. 8, vol. 4, p. 132). 



Length (rostrum exclusive), 2f-3 mm. ; breadth, 1^ mm. 



Mount Hope, Nelson. One of each sex, taken near the summit on the 

 14th February, 1915, by Mr. T. Hall. 



4105. Erirhinus leucocomus sp. no v. 



Suboblong-oval, moderately convex and nitid ; usually of a light rufo- 

 fuscous hue, elvtra with ill-defined dark marks, these most obvious behind, 

 legs and antennae fusco-fulvous ; pubescence rather unequally distributed, 

 transversely on the thorax ; fine, suberect, and pale yellow along the middle 

 of the elytra, but white, coarser, and irregular on other parts. 



Rostrum quite as long as thorax, arched, moderately slender, subparallel, 

 punctate -striate from the base to the antennal insertion. Thorax rather 

 broader than long, base and apex truncate, its sides moderately rounded ; 

 moderately coarsely but not closely punctured. Scutellum distinct but small. 

 Elytra oblong, curvedly narrowed posteriorly, nearly thrice the length 

 of thorax, a third broader than it is at the base ; distinctly striate- 

 punctate, interstices nearly plane, minutely seriate -punctate. 



Legs with fine setae, femora with a small denticle underneath ; tibiae 

 slightly mucronate and flexuous ; claws appendiculate at base. 



Scape rather slender, a Little thickened at the extremity, inserted between 

 the middle and apex and reaching the centre of the eye ; funiculus with 

 fine white setae, basal joint longer and stouter than the next, third and 

 fourth small and subquadrate, the following ones slightly broader and 

 shorter ; club hardly at all infuscate, nearly ovate. 



Fern. — Rostrum rather more slender, quite the length of head and thorax 

 together, similarly but more finely sculptured, scape implanted at or just 

 before the middle. In one example the thorax is rather shorter, and its 

 pubescence, like that of the head, is bright yellow. Underside piceous, 

 abdomen sometimes more rufescent, more or less transversely rugose and 

 distantly punctate, with decumbent white setae which become coarser near 

 the sides ; second ventral segment longer than either third or fourth, the 

 fifth with a shallow median fovea. 



Ocular lobes absent. Eyes rather flat, oval. 



The conspicuous, almost silvery scale-like hairs, which do not form 

 spots, render this distinct from other New Zealand sjjecies. 



(J. Length (rostrum exclusive), 2 mm. ; breadth, 1 mm. 



BuUer River, near Glcnhopc. Mr. T. Hall secured five individuals on 

 the 17th January, 1915.
