ADEMOSYNE TUMIDA, sp. nov. 

 Plate 6, fig. 2. 



The specimen has the whole of the right elytron and the distal 

 portion of the left preserved. 



ELYTRON, 7-5 mm. long, 2-9 mm. wide, Sculpture, eight punc- 

 tate strise, very faint except towards the apex ; interstices finely 

 granular. Shape, apex blunt, base slightly curved, suture nearly 

 straight, margin gently curved from shoulder to apex, marginal 

 border equal in width to that of the interstices, but wider towards 

 the shoulder. Convexity, rather low near base, much swollen towards 

 the apex. 



TYPE : Specs. 45a (mould), 456 (cast) (Plate 6, fig. 2). (B. D. 

 Coll.) 



OBS. : This is one of the two largest species of Ademosyne. 

 It is conspicuous because of its tumid appearance, its well-developed 

 interstices, the extreme fineness of the pittings on the strise, and its 

 strongly marked marginal border. 



ADEMOSYNE CAMERONI, sp. nov. 

 Plate 4, fig. 1. 



ELYTRON, 7-2 mm. long, 3 mm. wide. Sculpture, eight well- 

 developed punctate strise, the punctures being deep and clearly 

 marked. Shape, apex pointed, base nearly straight, suture and margin 

 almost equally curved and tapering to the apex, both sutural and 

 marginal borders equally narrow. 



TYPE : Specs. 46a (mould), 466 (cast) (Plate 4, fig. 1). (B. D. 

 Coll.) 



OBS. : The species is distinguished by the punctures being quite 

 separate and distinct. 



ADEMOSYNE PUNCTATA, sp. nov. 

 Plate 5, fig. 4. 



ELYTRON, 4 mm. long, 1 mm. wide. Sculpture, eight faint 

 strise ; these and the interstices both punctate, the distance between 

 the punctures being about equal to the width of the interstices. 



TYPE : Spec. 47a (mould), 476 (cast) (Plate 5, fig. 4). (B. D. 

 Coll.) 



OBS. : This is the only species of Ademosyne having both 

 interstices and striae punctate. Towards the base the punctate 

 character becomes more conspicuous.
