OF NEW ZEALAND. 1401 



articulation is elongate and much curved ; the second is about half 

 as long, very slender at the base, its form subtriangular ; the penul- 

 timate is nearly twice as long as the second, almost oviform, 

 gradually attenuated towards the extremity, so that the rather thick 

 needle-shaped terminal joint is not distinctly marked off. Tlie 

 labial ixtlpi have similarly-formed terminal joints, but the apical 

 one is more aciculate.

Capleston, Westland. This is an abundantly distinct species, 

 which, with pleasure, I name after its discoverer^ Mr. A. T. Cavell, 

 who sent me a siDccimen. 



Group-HYDROPHILIDiE. 



Saphydrus (Gen., p. 1014). 



2443. S. monticola, "-s. OUong-oval, broad, moderately 

 convex, glabrous, a little shining; fuscous, sides of thorax broadly 

 sordid-testaceous, elytral margins and apical region of the same pale 

 colour, legs red, antennae yellowish, club fuscous and opaque, palpi 

 fusco-testaceous. 



Head closely and distinctly punctate, with a line line extending 

 from each antenna to the vertex; eyea convex. Antennce short, 

 third joint elongate and slender ; sixth very short, strongly trans- 

 verse, as dull as the club. Thorax much broader than it is long, 

 its sides margined and feebly curved, scarcely at all narrowed in 

 front, anterior and posterior angles rounded, the base and apex 

 slightly bisinuate; its sculpture a little coarser than that of the 

 head. Scutcllum elongate, triangular, depressed. Elytra striate, 

 the strife become shallow behin::?, their whole surface punctured 

 as closely as and rather more coarsely than the thorax. 



Underside pale-brown, finely punctate and pubescent, as are also 

 the femora. 



The short, peculiarly-shaped thorax, and the obvious punctuation, 

 differentiate this species. 



Length, 2^; breadth, If lines. 



Mount Pirongia. One example, found amongst leaf-mould 

 gathered by Mr. A. T. Urquhart. 



Obs. — From tlie same source, but shaken off' trees, I have two 

 specimens of S. oblongus (No. 150). They differ from the type in 

 being nearly black, with red margins. Their posterior femora are 

 not glabrous, being, however, only indistinctly punctured and pubes- 

 cent. This precludes the separation of Dr. Sharp's four species into 

 two distinct genera. 



Rygmodus (Gen., p. 79). 



2444. R. alienus, ^i-s. Oblong-oval, moderately convex, shin- 

 ing ; head and thorax nearly black, elytra greenish-blue, sides of 

 thorax broadly rufescent, legs nigro-piceous ; palpi and antennae
