752 PERMIAN AND TRIASSIC INSECTS FROM N.S.AV., 



from base. The suture is well-marked: the whole elytron, in- 

 cluding the suture, is very finely but distinctly granulate all 

 over. Convexity slight. 



Type, Specimen No. 14 in Coll. Mitchell 



Family TENEBRIONID^. 

 Genus Adklidium, n.g. 



Broad, highly convex elytra of small size, evidently belonging 

 to a beetle with a broad, heart-shaped body. Suture narrow. 

 Sculpture consists of about nine slightly raised, longitudinal 

 striae, separated by wider interstices; the former regularly punc- 

 tate, each puncture being a tiny, shallow, circular depression. 



Genotype, Adelidium cordatum, n.sp. 



The name is given to suggest the close resemblance between 

 this elytron and those of the recent genus Adelium, well repre- 

 sented in Australia at the present day. 



Adelidium cordatum n.sp. (Text-fig. 14). 

 A beautifully preserved elytron, 4 mm. long, by 2*2 mm. wide 

 at its greatest width, near the base. Shave 

 well rounded towards the base, strongly 

 pointed at apex. SculptiLre : the longi- 

 tudinal striae very regularly punctate, the 

 distance between the punctures being 

 Text-fig. 14.* slightly less than the width of the inter- 



stices. 



Type, Specimen No. 17 in Coll. Mitchell. 

 It is possible that this species is closely related to some of the 

 species of Ademosyne described from Ipswich, but none of these 

 approach it in breadth or convexity.
