INSECT FxlUNA. 



85 



more strongly impressed than tlio others ; the apex of each elytron very 

 strongly and irregularly punctured. Underside piceous ; the sterna 

 moderately closely covered with long erect pubescence. Legs dark 

 tastaneous ; the anterior tibia; obtusely tridentate, the others bicarinate. 

 Length 14 — 16 mm. 



Low-lying lands, at light ; also found in the vicinity of Sydney, Kew South 

 Wales. 



IsoDox s"OCTTS, sp. nov. 



Elongate-ovate, rather robust, castaneous, shining, very conves ; prothoras 

 broadly transverse, smooth ; elytra rather strongly striate-punctatc, the stria; 

 abbreviated posteriorly; pygidium finely and irregularly punctured at 

 the base. 



Head narrowed in front, rather strongly ruguloso in front of the median 

 carina, which is moderately distinct, behind strongly and irregularly punctured, 

 especially near the sides; the base smooth. Antenna castaneous. Prothorax 

 uroadly transverse, strongly convex, somewhat narrowed in front ; the sides 

 strongly rounded ; the posterior margin somewhat impressed on each side of 

 *^lie middle. Scutellum smooth. Elytra with the sutural stria finely punc- 

 tured and moderately strongly impressed, the punctures of the discal strias 

 exceedingly coarse and somewhat irregular, the interstices moderately broad, 

 a broad impunctate interval between the sutural and the first discal stria; the 

 apex of each elytron moderately strongly and very sparingly punctured. 

 Underside pale castaneous ; the sterna thickly clothed with long silky 

 pubescence. Legs castaneous ; tibi» and tarsi inclining to pitchy ; anterior 

 wbia5 tridentate, the others bicarinate. Length 16 — 20 mm. 



This species is evidently allied to Isodon IcevicoUis, Macl., but may be 

 separated at once by the ]jresence of the broad impunctate intervals on the 

 elytra between the sutural and the discal strife, by having the sides almost 

 tree from punctures, and the head smooth at the base. In I. laevicoUis there 

 IS an iprggyiaj. row of punctures midway between' the sutural and the first 

 "iscal stria, and the striffi themselves are continued until they reach the 

 **ide ; the punctures in this species, although more irregular and much more 

 numerous, are not nearly so deep as in I. noctis.

 island. 



Melobasis empteia, sp. nov. 



*-oppery green, shining ; prothorax bright coppery, purplish on tlie disc ; 

 'outellum fiery copper ; elytra coppery, with piurple reflexions, irregularly 

 stnate-punctate, the third and fourth interstices obviously raised. 



-tlead nearly flat in front, coarsely and very densely punctured. Prothorax 

 t the base more than one-third broader than long, considerably narrowed in 

 '^OQt, rather strongly and sparingly punctured on the disc, the punctuation 

 ■ Ix'^ sides much stronger and denser, the anterior margin slightly produced 

 n the middle, its angles produced and rounded; the sides rounded ; the pos- 

 erior margin nearly straight. Scutellum excessively finely punctured, 

 ytra about twice as long as broad, coppery, inclining to fiery near the 

 Jiture and about the middle, rather strongly and irregularly striate -punctate; 

 ^e sides straight and nearly parallel for about two-thirds of their length.
