Group Am iiomkmdae. 



Anchomenus Bonelli. Man. N.Z. Coleopt., p. 20. 



4159. Anchomenus arnaudensis sp. no v. 



Subdepressed. nitid, black. legs rufo-piceous, palpi and tarsi light red, 

 the labruni. mandibles, and basal three joints of antennae pitchy-red, 

 remaining joints dull fusco-rufous. 



Head, including the large prominent eyes, almost as broad as thorax, 

 with well-marked 1'rontal impressions ; labrum distinctly emarginate. Thorax 

 only a trifle broader than long, base and apex subtruncate, a little wider 

 before the middle than elsewhere, slightly curvedly narrowed anteriorly, 

 gradually narrowed towards the subacutely rectangular posterior angles ; 

 the discal furrow extends from near the base to beyond the oblique sulci- 

 form frontal impressions ; basal fossae large, extending from the somewhat 

 reflexed lateral margins more than half-way towards the middle of the base, 

 each with a slightly curved impression which tapers towards the front. 

 Elytra oblong-oval, thrice the length and in line with the hind thighs, 

 double the width of thorax, gently narrowed towards the base, obliquely 

 narrowed posteriorly, with obtuse apices ; their striae are impunctate, 

 quite distinct, and irregularly confluent behind, the scutellar ones are 

 short ; interstices nearly plane, the third usually quadripunctate. 



Tarsi finely grooved above. The antennae barely attain the middle 

 femora, their seventh joint reaches the thoracic base. The shoulders are 

 narrow. With the exception of A. otagoensis (54) it has no near ally ; the 

 elytra! striae of 54 are narrower and more sharply impressed, the antennae 

 are longer, and these, like the legs and palpi, are of an obscurely tawny hue. 



<$. Length. 11 mm. ; breadth, 4 mm. 



Mount St. Arnaud, Nelson; elevation, 5,000ft. A single male, found 

 by Mr. T. Hall ; 15th June, 1916. 



4160. Anchomenus hallianus sp. now 



Oblong, slightly convex ; shining black, mandibles, antennae, legs, 

 and palpi rufo-piceous, these last with fulvescent tips. 



Plead narrower than front of thorax, exclusive of the large prominent 

 eyes, with well-marked frontal impressions, finely punctate and wrinkled 

 between the eyes ; labium almost straight and sex-punctate in front. 

 Thorax a third broadei than long, base truncate, apex moderately emargin- 

 ate, the sides well rounded, widest at or just before the middle, but some- 

 what incurved towards the distinct rectangular posterior angles, lateral 

 margins well developed and moderately reflexed ; disc with faint transverse 

 striae, the central groove ends in the curvate frontal impression and does 

 nut reach the base, which has large foveae. Scutellum triangular. Elytra 

 rather broader than thorax at the base, almost thrice its length, tapering 

 evidently but gradually near the apices; they are deeply striate, with 

 elongate scutellar striae ; interstices convex, the third, fifth, and seventh 

 rather broader than the others; marginal channels broad, with about five 

 moderate punctures Dear the base and as many coarser ones behind. 



Antennae distinctly pubescent from the fourth joint onwards, extending 

 to just beyond the middle thighs. 



Terminal joints of palpi a little shorter than usual and truncate at apex. 

 Thorax with a single Betigerous puncture on each side before the middle 

 and another at the hind angle. Basal three joints of anterior tarsi 

 moderately expanded, narrowed towards the base, the first longest, with
