420 COLEOPTERA 



anteriorly ; the maxillary palpi of the male with the penultimate joint 

 shorter than the second ; the apical large, slender at the base, greatly 

 expanded apically, with a deep semicircular external excision, and its 

 front portion truncated at the end. Antenna eleven-jointed, not so long 

 as the body, filiform, and inserted in front of the eyes ; second joint 

 small ; joints three to ten gradually decrease ; eleventh rather short, 

 sub-ovate. Prothorax scarcely convex, longer than broad, dilated 

 laterally near the front, base and apex truncate, with fine reflexed 

 margins. Scutellum small. Elytra elongate, wider behind than in front, 

 apices rounded, leaving the pygidium exposed. Four front femora sub- 

 linear, the posterior strongly inflated, and grooved below for the recep- 

 tion of the tibiae ; the two anterior pairs of tibia nearly straight, the 

 hind pair thick, greatly flexuose and inwardly produced at the apex as a 

 somewhat flattened process ; each with two short spines ; tarsi with the 

 second and third joints of the two front pairs obconical, the fourth sub- 

 quadrate and superficially excavated for the reception of the slender 

 apical joint, which is nearly as long as the first. 



In ihefema/e the hind legs are similar in form to the others, and the 

 terminal joint of the palpus, though dilated, is only about twice as wide 

 as the penultimate, and the elytra are broader. 



NOTE. These characters have been derived from examples in my 

 own collection, and will serve to indicate, in some degree, the forms of 

 the other New Zealand genera of the GEdemeridse. 



736. S. cyaneus, Fabricius; Ent. Syst., ii., 75. Body dark 

 blue, moderately shining, palpi, tarsi, and apical joints of the antennae 

 piceous. Head finely punctate, with a longitudinal depression more or 

 less distinct on the clypeus, and almost nude. Prothorax a little uneven, 

 finely and rather closely punctured, with a few short fuscous hairs. 

 Each elytron with the suture and two discoidal lines slightly elevated, 

 the whole of the surface being more or less finely and rugosely punc- 

 tured, and clothed with short fuscous pubescence. 



Length, 6 lines. 



Described from specimens which I found at Tairua, on the inflores- 

 cence of Leptospermum. 



The species is identical with White's Selenopalpus chalybeus. 



Sessinia. 



Pascoe ; Journ. Entom., ii., p. 45. 

 NOTE. I have not seen the description of this genus. 



737- S. Strigipennis, White; Voy. Er. Terr., Ins., p. 12. Pale 

 testaceous, with an indistinct dorsal line on the thorax, and the inter- 

 stices of the elytra infuscate but seldom very dark. The head and 

 thorax are finely and rather closely punctured and sparsely pubescent. 

 Scutellum large, triangular. The elytra have the sutural and two ill- 

 defined discoidal lines on each paler than the interstices, and the whole 

 of their surface is more or less finely punctate and rugose and clothed 

 with fine pallid hairs.
