LYMEXYLONID^E. 



HTLECOEirS PEBTACa'S, sp. IIOV. 



Elongate, clothed with short griseous pubescence, head and prothorax 

 piceous, the latter longer than broad, finely and densely rugulose-pimctate ; 

 elytra ferruginous, very finely and closely punctured, each with two 

 feebly elevated costa;. 



Head rather large, finely rugulose between the eyes, which are very large, 

 prominent, and contiguous in front. Antennae reddish testaceous, clothed 

 with fuscous pubescence, the terminal joint elongate, acuminate at the 

 estremity. Prothorax decidedly longer than broad, narrowed behind, densely 

 and irregularly punctured, finely and closely pubescent, the pubescence more 

 distinct near the sides ; the anterior margin arcuate, the angles rounded ; 

 sides with a slight prominence in the middle. Scutellum longer than broad, 

 finely rugulose-punctate. Elytra almost parallel-sided, finely and very- 

 closely punctured, rounded behind ; each elytron with two feeble linear 

 elevations on the disc, and a third very indistinct but similar elevation near 

 the side. Underside reddish testaceous, clothed with fine pubescence, 

 and very finely and densely punctured. Legs reddish testaceous. Length 

 15-21 mm. 



A single specimen dug out of a fallen log ; also found at Kiama, m the 

 Illawarra district of Xew South "Wales. 



Apparently a very distinct species differing from the few known Eastern 

 forms in having the prothorax, which is without a central furrow, decidedly 

 longer than broad. Its nearest ally is probably Ilylecoetus javanicus, Chev.,t 

 a species which ranges from Sumatra to North-west Sow Guinea. 



TENEBEIONID.'E. 



♦HOPATETJM CALTULTJM, sp. nov. 



Elongate ovate, moderately convex, dull opaque black, very sparingly 

 clothedNvith extremely fine fulvous pubescence ; prothorax extremely finely 

 rugulose ; elytra very obscurely punctate-striate, the intervals very minutely 

 rugulose. 



Head broadly transverse, very finely rugose punctate ; the sides produced 

 in front of the eyes. Antenna ferruginous. Prothorax strongly emarginate 

 in front ; the sides strongly rounded ; the posterior margin bisinuate. 

 Scutellum transverse, rounded behind, finely punctured at the base. Elytra 

 sub-parallel for two-thirds of their length, then rounded to the apex, 

 obscurely punctate-striate ; the interstices broad, nearly flat, and minutely 

 '^ugulose. Underside somewhat shining, moderately closely and irregularly 

 punctured. Legs piceous, tibia and tarsi inclining to ferruginous. Length 

 6-7 mm. 



Allied to Ilopatrum Mastersi, Macl., and the Norfolk Island H. insulanum, 

 Oil-, J but differs in its smoother appearance and more obscurely striate 

 elytra. To the naked eye its surface appears to be almost smooth, butAvhen 

 examined under a pow-erful lens it is seen to be minutely rugulose or 

 roughened. 



Platxdema si'iCATA, sp. nov. 



Ovate, pitchy blaclv, shining, moderately convex, prothorax extremely 

 finely and rather closely punctured ; elytra finely punctate-striate, the striaB 

 uot extending to the apex, the interstices broad and slightly raised.
