 Erirhinus Schoenherr. Man. N.Z. Colcopt., p. 449. 



4103. Erirhinus dilucidus sp. nov. 



Oblong, niodoratcly convex, subnitid ; nigro-fuscous, the thoracic apex, 

 suture, and extremity of elytra more or h'ss rufo-fuscoiis ; elytra with a pale, 

 almost ivory-like basal spot on each of the third interstices, an interrupted 

 cured fascia before the middle, and a more conspicuous one just below the 

 summit of the posterior declivity equally ])a]lid ; legs variegate, femora 

 at the base and the lower half of tibiae pallid, the upper part of these latter 

 dark fuscous ; antennae and tarsi rufo-testaceous, but the club and first 

 joint of funiculus are infuscate ; pubescence scanty, slender, ashy, and 

 inconspicuous. 



Rostrum moderately arched and slender, subparallel, a third longer than 

 thorax, slightly bisulcate and punctate behind the antennae. Thorax 

 truncate at base and apex, a little broader than long, contracted in front, 

 with somewhat rounded sides, rugosely but not coarsely punctate. Scutel- 

 lum small and smooth. Elytra almost thrice the length of thorax, dis- 

 tinctly broader than it is at the base, gradually narrowed and deflexed 

 behind ; evidently punctate-striate, the third and fourth striae confluent 

 just behind the first fascia. 



Sca])e implanted near the apex, attaining the front of the eye, slender, 

 a little thicker near the extremity ; funiculus with fine dark setae, basal 

 joint longer and considerably stouter than the moderately elongate second, 

 third and fourth slightly longer than the short following ones ; club 

 oblong-oval, densely pubescent, triarticulate. 



Underside pubescent ; breast fuscous, abdomen testaceous. Prosternum 

 widely incurved. Metasternum plane. Basal ventral segment rather 

 longer than second, subtruncate between the coxae, third and fourth, singly, 

 slightly shorter than second, together shorter than fifth. 



Ocular lobes absent. Eyes coarsely facetted, slightly prominent, sub- 

 rotundate, situated on the upper surface close to the thorax, distant from 

 each other about half the width of the rostrum. Legs of moderate length, 

 normal ; tarsi with finely setose soles, claws strongly dentate at the base. 



The coloration and marks render it distinct from all other allied species. 



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



Woodhen Bend, near Glcnhope. -A single individual, found by Mr. T. 

 Hall on the 20th June, 1915. 



4104. Erirhinus altivagans sp. nov. 



Elongate, moderately convex and nitid ; nigrescent, femora fusco- 

 castaneous, tibiae and tarsi paler ; elytra with a few erect minute grey 

 setae, the sides of thorax with longer subdepressed ones. 



Rostrum arched, parallel, moderately stout, as long as thorax, finely 

 subseriate-punctate. Eyes rather flat, just free, subrotundate, distant from 

 each other. Thorax rather broader than long, slightly rounded and a little 

 broader before the middle than elsewhere, more contracted in front than 

 behind, base and apex truncate, distinctly and moderately closely punc- 

 tured. Scutellum small and rather narrow. Elytra oblong, more than 

 double the length of thorax, rather wider than it is at the base, gently 

 narrowed behind ; distinctly and closely substriate -punctate, interstices 

 nearly plane, minutely seriate-punctate. 



Antennae more or less rufescent ; scape inserted between the middle 

 and apex ; basal joint of funiculus nearly twice the length of the second,
