mediate pair distinctly, tlie posterior ^vidcly distant. Meta- 

 stermun short. Abdomen elongate^ l)asal two segments 

 broadly impressed^ the first longest, third and fourth mode- 

 rately short, with deep straight sutures. 



The rostrum is about half the length of the thorax, and is 

 almost pterygiate at the apex, so that the scrobes are quite 

 open above and somewhat similar to those of an Ot'io- 

 rhynchus. As the insect is blind and without the scutellum 

 and the tibial hooks, its position in the section having a 

 seven-jointed funiculus is apparently unique. 



Hedmus ruhidus, sp. n. 



Body moderately convex, a little nitid, ferruginous ; an- 

 tennae and tarsi testaceous ; its clothing consists of a few 

 erect slender grey hairs. 



Rostrum with some slender pallid squamte near the base. 

 Thorax almost nude, not twice as long as it is broad, slightly 

 wider before the middle than elsewhere, its sides gently 

 rounded, its surface moderately coarsely but not closely 

 punctured. Elytra rather wider than thorax at the base, 

 twice its length, their sides nearly parallel, apices simple, 

 rounded ; distinctly and moderately coarsely striate-punctate, 

 interstices rather narrow, plane, each with a series of minute 

 punctures ; they bear numerous erect, short, grey setae. 

 Legs finely setose; femora long and somewhat clavate; 

 tibiae stout, a little flexuous, the intermediate and posterior 

 unarmed at the extremity. Metasternum and basal ventral 

 segments distinctly but not closely punctate. 



Length (rostr. inch) 1, breadth \ line. 



]da Valley, Otago. 



One example found by Mr. J. H. Lewis. 



Group Scolytidae. 

 Mesoscolytus, gen. nov. 



Body narrow, cylindrical. Head deeply immersed in the 

 excavate pronoium. Antenna implanted close to the eyes, 

 basal joint curvate, elongate, twice the length of all the 

 others combined ; second stout, triangular; remaining joints 

 gradually expanded, extremely short, and so closely articu- 

 lated as to be almost indistingviishable. Club large, flat- 

 tened, and compact, broadly oval, not visibly articulated 

 above. Eyes depressed, distinctly facetted, strongly trans- 

 verse, widely distant. Thorax large, without lateral margins. 

 Scutetluin small. Lp(/s slender, femora laterally compressed ;
