OF NEW ZEALAND. 853 



Irenimus (p. 443)- 



1517. I. pilosellus, n.s. Sub-ovate, moderately convex, 

 piceous ; covered with small, flat, greyish-brown scales and pallid 

 setae ; antennae and tarsi obscure-red. 



Rostrum shorter than thorax, moderately stout, dilated apically, 

 not obviously carinated, punctate and squamose; the sides and apex 

 fringed with pale hairs ; scrobes apical, visible from above, indefi- 

 nitely prolonged obliquely. Antenna reaching backwards to base of 

 thorax ; the scape to its apex gradually thickened, bearing grey~ 

 hairs. Funiculus y-articulate, the two basal joints nearly equal, 

 the others decrease in length, obconical ; club oblong-oval, 3-jointed. 

 Eyes free, rather depressed, obliquely oval, moderately facetted. 

 Prothorax about as long as broad, without distinct ocular lobes, 

 having only a wide, slight incurvature behind the eyes ; base feebly 

 rounded, the sides broadly ; punctate and squamose, exhibiting 

 slight inequalities of surface, and a broad oblique impression towards 

 each front angle. Scutellum minute. Elytra elongate-cordate, a 

 little wider than thorax, and incurved, at the base, shoulders oblique, 

 narrowed and deflexed behind ; disc but little convex, almost striate- 

 punctate, the third and fifth interstices moderately elevated at the 

 top of the hind-slope ; apex griseous and greatly narrowed. Femora 

 clavate ; tibia flexuose, the anterior mucronate, posterior expanded 

 and hollowed at apex ; tarsi stout. Underside rather densely clothed 

 with fine elongate greyish hairs ; two basal segments of abdomen 

 large, broadly impressed on the middle ; apex of prosternum deeply 

 incurved. 



I have not seen any authentic exponent of this genus ; but this 

 species, though apparently rather narrow, seems to agree structurally 

 with the diagnosis, so far as I can judge. The elytra, though much 

 narrower than in an Australian Perperus near the middle, are 

 certainly broader at the base. Nos. 1231 and 1232 belong to 

 Irenimus. 



Length (rost. incl.), 3 lines; breadth, ij-. 



Dunedin : Mr. T. Chalmer. One example. 



1518. I. bicostatus, n.s. Piceous, covered with greyish-brown 

 scales and short grey setae, legs and antennas obscure-red, bearing 

 greyish hairs. 



Rostrum shorter than thorax, punctate and scaly. Prothorax 

 longer than broad, sub-truncate at base, obtusely rounded laterally, 

 widest before the middle, obliquely impressed in front, longitudinally 

 at the base, presenting a somewhat rough or uneven appearance, yet 

 neither tuberculate nor rugose. Scutellum small. Elytra elongate- 

 cordate, sub-acuminate behind, broader than thorax, and slightly 

 incurved at base ; dorsum slightly convex, sub-striate-punctate, third 

 and fifth interstices elevated from the base to the posterior declivity, 

 where they assume the form of nodose elevations. Underside covered 

 with longish pallid hairs. 



Like I. pilosellus, larger, and with costiform elytral interstices. 

 Both are similar in structure.
