838 REMARKS ON AUSTRALIAN PTINID^E, 



This genus connects Diplocotes, Westw. (Thes. Ent. Oxon, pi. 3, 

 fig. 6) with Ftinus, but is sufficiently distinguished by its elongate 

 and deeply impressed prothorax (which is nan-owed and strongly 

 constricted behind) and by its filiform eleven jointed antennae. 



DiPHOBIA FAMILIARIS, Sp. n. 



Elongate-ovate, strongly convex, pitchy lilack, somewhat 

 shining. Head rather finely and closely punctured, with an 

 indistinct median line ; the anterior margin bisinuate. Antennai 

 clothed with short grey pubescence ; first four joints finely rugose. 

 Prothorax considerably longer than broad, slightly narrowed 

 behind, sparingly clothed with short bristly grey hairs, distinctly 

 striolate, the curved impression more strongly impressed in the 

 middle than near the margins ; the sides rounded in front, rather 

 strongly constricted at the apical two-thirds. Elytra globose, 

 impunctate, with indistinct traces of stride, four moderately strong 

 basal impressions ; the suture feebly raised. Underside coloured 

 as above ; sterna moderately strongly and closely punctured ; 

 abdominal segments less strongly and sparingly punctured. Legs 

 pitchy. Length 2-i-3 unn. 



South Australia. Under bark ; apparently an alnxndant 

 species. 



Immature specimens have tlie elytra and legs of a reddish 

 testaceous colour. 



Enasiba, gen. nov. 



Body elongate, convex. Head transverse, constricted just in 



front of the eyes. Eyes small, lateral. Antenn:e eleven jointed (?), 



(1) the basal joint longer than broad, the second about half as long 



as the first, ol)Iiquely truncated Viehind, the third nai-rower in 



front than behind, fourth to sixth joints similar to the third in 



shape, but considerably larger, seventh and eighth moniliform 



smaller than the preceding, ninth globose and enlarged, tenth 



smaller, slightly longer than broad. Prothorax elongate, anterior 



(1) The unique spechnen upon which this genus is founded appears to 

 have lost the terminal joint of each of its autenn;e.
