250 COI-KOl'TKRA. 



I'uiuuk'tl apices; tlicy are tsubstriate-imuctate, the sutuial striae only 

 are modera,tely distinct ; interstices witli tine serial punctures, the 3rd 

 bent outwardly at the extremity. 



Legs moderately stout; tibiae strongly uncinate; penultimate tarsal 

 joints hollowed above and sublobate. 



Scape implanted before the middle, nearly straight, very gradually 

 and slightly thickened; 2nd joint of the funiculus smaller than the 1st 

 but rather longer than the next, 5tli subquadiate; club densely pubescent, 

 oblong-uval, of about the same length as the last thi-ee joints of the 

 funiculus combined. 



With the exception of the more convex, fusifoiin body, this species 

 agrees structurally with Bhiuanisus. The first part of the description 

 will lead to its recognition. 



(J. Length (rostrum inclusive), neaidy 2| mm. ; breadth, fully 5 mm. 



Curiosity Gully, near Methven. Oue found by Mr. T. Hall on the 

 9th August, 1912, amongst leaf-mould. 



3654. Sericotrogus plexus sp. nov. Sericotrogus Wollaston, Man. N.Z. 

 Cole(>])t., p. 521. 



Elongate, narrow, slightly convex, subopaque; fusco-piceous, legs 

 dark fusco-rufous, antennae and tarsi light chestnut-red; sparingly 

 clothed with yellow, rather long and slender, subdecumbent hairs and 

 a few ashy inconspicuous ones. 



Rostrum nearly a third shorter than the thorax, slightly arched, 

 moderately stout, gently narrowed behind the antennal insertion, nearly 

 smooth along the middle, finely punctate near the sides, more distinctly 

 and closely towards its base. Eyes hardly at all prominent. Thorax 

 suboviform, a third longer than broad, a little rounded and wider just 

 behind the middle than elsewhere, gradually narrowed anteriorly, 

 slightly constricted near the apex, not at all depressed; distinctly but 

 not very closely punctate, with very minutely sculptured intervals. 

 Scutellum small but distinct. Elytra wdthout depressions, subparallel, 

 rather wider than the thorax at the base, more than twice its length, 

 narroAved near the obscurely rufescent, singly slightly rounded apices; 

 they are moderately closely striate-punctate, the sutural striae most dis- 

 tinct and becoming deeper behind; interstices wiith almost duplicate 

 series of minute punctures and appearing rugose, the 3rd do not reach 

 the extremity, but are bent and prolonged forwards at the sides. 



Legs stout and moderately elongate; penultimate joints of anterior 

 tarsi moderately expanded and evidently bilobcd, those of the other pairs 

 less distinctly. 



Scape inserted just before the middle, somewhat curved, moderately 

 incrassate towards the extremity; 2nd joint of the funiculus nearly as 

 long as the basal, joints 3-5 obconical, 3rd vei-y slightly longer than 

 broad ; club finely pubescent, elongate-oval, about as long as joints 2-5 

 of the funiculus taken together. 



Differentiated principally from Agasfeguus by the manifestly bilobed 

 antei'ior tarsi and the unimpressed thorax and elytra; and from 

 Sertrotrogits l)y the long, indistinctly (|nadriai-ticnlatc club, more 

 elongate antennae and curvate scape, longer rostrum, and less prominent 

 eyes. 



Length (rostrum inclusive), 3i mm. ; l)readth, ^ mm. 



Bell Rock, near Methven. One found by Mr. T. Hall, on the 15tb 

 September, 1912, amongst decaying leaves on the ground.
