92 LORD HOWE ISLAND. 



TJnderside sparingly clothed, with ashy scales in the middle, the sterna and 

 abdominal segments with ochraceous scales at the sides. Legs finely pubes- 

 cent. Length 10 — 11 mm. 



Appears to be distinct from any of the described species of this peculiarly 

 Australian genus. 



ISACAIfTHA INCULTA, Sp. UOV. 



Elongate, greatly narrowed in front, piceous, somewhat shining, covered 

 Avith fine slaty gray pubescence ; the pro thorax and elytra finely granulate, 

 the former only slightly constricted in front. 



Head rather finely granulose, a line of dusky white pubescence on the 

 inner mai-gin of the eyes, which are large and prominent ; rostrum long, 

 cylindrical, nearly straight, rugulose-punctate for two-thirds of its length 

 with the apical third ferruginous, shining, and almost impunctate. Antennse 

 black, with the base ferruginous ; the second joint very short; the third slightly 

 longer than the first. Prothorax distinctly and not very closely granulate ; 

 the sides rounded, narrowed, and very slightly constricted in front. Scutellum 

 transverse, clothed with ochraceous pubescence. Elytra distinctly and 

 irregularly granulate, the suture slightly elevated. Underside piceous, 

 clothed with fine slaty gray pubescence ; the sterna rather thickly, and the 

 abdominal segments sparingly, covered with ochraceous pubescence. Legs 

 finely pubescent. Length, 9 — ]3 mm. 



This species has the form of Isacaniha congesta, Pasc, except that the 

 prothorax is much less constricted in front ; the pubescence is slaty gray 

 above, and the elytra are less strongly granulate than those of the other 

 species. 



Embaphiodes ptxidatI'S, Pasc. 



Emlaphiodes pyxidattts, Pascoe, Ann. Mag. Nat. Hist., (4) XIII, p. 419, 

 (1874) ; loc. cit. XVI, pi. 1, fig. 6 (1875). 

 This singular form appears to be very rare. I have only seen a single 

 specimen. 



Imalitiius, sp. ? 

 An old and discoloured specimen of a species evidently belonging to this 

 genus, and apparently distinct from /. patella, Pasc, is in the collection of 

 the Australian Museum. 



*EUTHTEEHINTIS MEDITABUNDUS, Fair. 



'Eutliyrrliinus meditahundus, Fabricius, Syst. Ent., p. 139. 

 Widely distributed and variable ; occurs in Norfolk Island. 



Aethkeus cicateicosus, Pasc. 



Aetlireiis cicatricosus, Pascoe, Ann. Mag. Nat. Hist., (4) XVI, p. 65, pi. 1, 

 fig. 8 (1875). 

 I have seen a single specimen agreeing in every respect with the descrip- 

 tion of this sjDecies. 



Htbomoephus mela-NOsomus, Saund. Sf Jelc. 



SyhomorpTius melanosomus, Saunders & Jekel, Ann. Soc. Ent. France, (3) 

 III, p. 804, pi. 15, fig. 8 (1855). 

 A remarkable endemic form. A large number of fragments and dead 

 remains of this species were found by Mr. Masters under logs and in rotten 

 wood during his visit to the island in June, 1SG9. As far as I am aware, this 

 is the last occasion on which the insect has been found, none of the 

 collectors who have recently visited the island having obtained it.
