84 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Coleopiera. 



The following notes appear in my description of D. tarsalis : Male — Anterior 

 tarsi with fine setae at the sides, the basal 4 joints somewhat expanded, 3rd trans- 

 versely cordiform ; the basal 2 largest, 2nd strongly transverse but not exactly 

 cordate ; these two articulations broadly dilated inwardly, and provided underneath, 

 at the inner side, with patches of grey spongelike pubescence. 



These notes on my two species not only define the actual structure of the male 

 anterior tarsi, but incontestably prove that Dr. Sharp's genus is abundantly distinct, 

 and, moreover, differentiated by structural characters that cannot well be mistaken. 

 He, no doubt, had seen female specimens only. 



Diglymma castigatum, sp. nov. 



Stthcylindrical, medially narrowed, slightly convex, a little nitid ; black, legs 

 rufo-piceous, palpi and antennae more rufescent. 



Head narrower than thorax, with well-marked frontal impressions, which, as 

 well as the back part, are more or less finely punctured. Eyes only moderately 

 prominent. Thorax apparently elongate, yet slightly broader than long, rather 

 wider near the middle than elsewhere, its sides gently rounded, more narrowed 

 towards the obsolete posterior angles ; the lateral margins fine but distinct, near 

 the base they are a little sinuate and curved inwards^ so that there they do not limit 

 the true sides, which are thus slightly uncovered ; apex truncate, base slightly 

 incurved ; basal fossae small and nearly sulciform, situated at the sides but at some 

 little distance from the base, the dorsal groove deep but not attaining the base or 

 apex, sometimes a few fine punctures may be seen in front of the base. Elytra 

 elongate, a little broader than the thorax ; in one specimen but little, in another 

 very gradually yet a good deal, narrowed posteriorly ; one example has 8 series 

 of fine but distinct punctures on each elytron, connected by extremely slender linear 

 impressions which can hardly be termed striae, the other has more feebly impressed 

 sculpture ; in both, at the base, there is a transverse series of rather coarse deep 

 punctures, there are also 3 or 4 moderate punctures near each side. Antennae with 

 very scanty pubescence, joints 4 to 10 moniliform, 11th ovate and acuminate. Tibiae 

 not incrassate or prominent at the extremity, the intermediate coarsely setose ex- 

 ternally. 



This is the smallest and most slender species. 

 ? . Length, 3|-4J lines ; breadth, IJ-lf lines. 



The Snares ; two females. 



This is another of Mr. G. V. Hudson's discoveries. 



Synteratus, gen. nov. 



Body compact, elongate-oval, slightly convex, glabrous, apterous. 



Head rather narrower than front of thorax. Eyes longitudinally oval, just 

 free from the thorax, not at all convex, distinctly faceted. Lahrum transverse, 

 entire. Palpi setose, moderately elongate ; 2nd joint of the maxillary stout, elongate, 

 arched externally ; 3rd elongate, slender at the base, gradually yet considerably 

 dilated towards the extremity ; the terminal thick at the base, tapering towards the 

 acuminate apex, it equals the preceding one in length ; terminal joint of the labial 

 similar to that of the maxillary. Mentum bisetose, with a simple central tooth 

 which is truncate in front. Antennae filiform, the basal 2 joints and half of the
