4:22 COLEOPTERA. 



Rostruin aliuiist as loii^ as thorax, its frontal half a little dilated, its 

 distinct basal carina fringed with setae. Thorax a fifth longer than broad., 

 a little wider before the middle than elsewhere, somewhat abruptlv con- 

 tracted in front, slightly and very gradually narrowed behind, its base 

 sharply truncate ; disc rather closely, coarsely, and deeply punctured, more 

 finely in front, with a rather deep basal impression. Elytra just double the 

 length of thorax, rather wider near the posterior fenun'a than in front, 

 somewhat abruptly narrowed and subvertical behind ; the base is quite 

 truncate and a little broader than that of the thorax, and there the sides 

 for a sliort distance, when examined from above, appear straight and 

 abruptly narrower than the part liehind it ; the basal depression is smooth 

 and deep, it occupies half the width, and is bordered by the rather sharply 

 elevated 3rd interstices, which, however, are simple further back ; the 5th 

 are a little uneven behind the middle and terminate as oblong but not 

 conspicuous nodosities ; the inner pair of serial punctures, on each elytron, 

 are oblong, the others are less regular, the declivity is substriate. 



Scape with coarse pale setae ; 2nd joint of funiculus as long as tlu- 

 basal, the others rather broader than long ; club ovate. 



Legs elongate, bearing rather slender erect setae, slightly arched 

 externally, indistinctly mucronate, the anterior rather more elongate, and 

 distinctly narrowed outwardly at the extremity ; the penultimate tarsal 

 joint, like that of L. setirodris, though excavate above, is not lobate. being 

 truncate at the apex. 



The description of the basal portions of the thorax and elytra is suffi- 

 ciently characteristic. The thorax is rather longer and narrower than . 

 usual, and its sculpture differs from that of L. setirostris. 



Length (rostrum inclusive), 5 J- mm. ; breadth. If mm. 



Mount Dick, Lake Wakatipu. A solitary individual tliscovered by 

 Mr. T. Hall, amongst dead leaves, on the 17th Mai'ch, 1914.. 



3897. Lithocia rectisetosa sp. nov. 



Subopa(pie, nearly plane, fusco-testaceous ; bearing numerous single, 

 straight, erect, nigrescent setae, and a pair of distant pale crests on the 

 summit of the posterior decli\'ity. 



Rostrum arched, rather shorter than thorax, its frontal half dilated, 

 the basal indistinctly carinate and covered with .short, pale, curled setae. 

 Thorax of equal length and breadth, widest before the middle, somewhat 

 abruptly narrowed in front, more gradually behind, very slightly uneven, 

 distinctly but irregularly pmictate. Elytra hardly double the length of 

 thorax, a good deal narrowed but not quite vertical behind, each with a 

 basal notch inside the shoulder for the accommodation of the thoracic 

 angle, so that the shoulders appear to clasp the base of the thorax ; they 

 are, except at the sides, quite regularly and distinctly seriate-punctate 

 but becoming substriate behind ; scutellar region depressed, 3rd interstices 

 evidently elevated at the base. 



Legs with a few pale, slender, outstanding setae, tibia only slightly 

 flexuous, distinctly mucronate at the extremity, the hind pairs especially. 



Scape moderately stout, very gradually incrassate ; club short, sul)- 

 rotundate, indistinctly articulate. 



There can be no difiiculty in identifying this remarkable little species. 



Length (rostrum inclusive), 3f mm. ; breadth, H mm.

 decaying leaves, on the 9th October, 1913.
