Broun. — New Genera and Species of Coleoptera. 137 



Length (rostrum exclusive), If mm. ; breadth, | mm. 

 Erua. One only, found amongst dead leaves on the ground ; Janu- 

 ary, 1910. 



3318. Acalles contractus sp. no v. 



Convex, rather long and narrow, somewhat contracted at the junction 

 of the thorax and hind-body, without crests or tubercles, subopaque ; 

 fusco-rufous, antennae fulvescent, club fuscous ; sparsely covered with 

 flavescent squamae, some of which on the hinder part of the elytra are 

 coarser and erect, those on the legs are equally coarse but paler or greyish. 



Rostrum rufescent, sliining, nearly smooth, shghtly arched, just per- 

 ceptibly narrowed towards the base. Thorax a little longer than broad, 

 widest behind the middle, narrowed, but not abruptly, towards the apex, 

 somewhat contracted at the subtruncate base ; it is moderately coarsely 

 and closely punctured. Elytra oviform, not twice the length of the thorax, 

 very slightly wider than it is at the base, widest near the middle, the de« 

 chvity not vertical ; with distinct, seemingly impunctate, sutural striae, 

 the lateral sculpture ill defined. 



Legs long and thick ; 3rd tarsal joint expanded and bilobed. Scape 

 inserted just behind the middle, barely reaching the eye, gradually thick- 

 ened ; 2nd joint of funiculus slender, shorter than 1st, joints 3-7 subequal, 

 small ; club oviform, densely pubescent, not distinctly annulate. Eyes 

 not prominent, subrotundate. Scutellum absent. There are no ocular lobes. 



Its nearest congeners are 1275 and 1745, from both of which it can be 

 separated at once by the yellow squamosity. Ultimately all three probably 

 will be detached from Acalles. 



Length (rostrum exclusive), 1| mm. ; breadth, | mm. 



Erua. One found amongst vegetable matter on the ground in Janu- 

 ary, 1910. 



3319. Tychanus costatus sp. nov. Tychanus Pascoe, Man. N.Z. Coleopt., 



p. 498. 



Convex, broad, nigrescent, densely covered with tawny scales, on the 

 bind-body they are rather finer and more rufescent than those on the 

 thorax ; on each elytron, near the hind thigh, a very irregularly formed 

 patch of white squamae extends from the side half-way to the suture ; 

 antennae and tarsi piceo-rufous. 



Rostrum a fifth shorter than thorax, not arcuate, broader at the base 

 than elsewhere, opaque ; its frontal half glabrous and finely yet distinctly 

 punctate, the basal more coarsely sculptured, and finely squamose ; there 

 is an interanteunal groove. Thorax about a third broader than it is long, 

 not as broad as the elytra at the base ; its apical portion, about a third 

 of the whole length, contracted to the width of the head, which it partly 

 covers ; the basal part rather broader in front than behind, and with a 

 pair of obtuse median elevations near the front ; its punctation is invisible. 

 Scutellum quite nude and distinct. Elytra broader than thorax, the 

 shoulders obtusely prominent, behind each of these there is a rather large 

 lateral prominence ; the posterior declivity is not quite vertical, and at 

 the apex is obtusely prominent at each side ; along each, at a short distance 

 from the suture, an obtuse ridge extends from the base, near which it is 

 most elevated, and terminates at the declivity, the sutural area has some 

 coarse punctiform impressions and minute granules ; nearer the side a
