comes scarcely recognizable, is the emarginate apex of the 

 prothorax. The subbilobed form of the tarsi is the most per- 

 manent of all, and is absent from none of the new genera here 

 recorded. The mentum and lower lip seem subject to con- 

 siderable modifications ; but, after the examination of those of 

 several species, I think it would be unsafe to depend on them 

 alone for generic characters. The subjoined tabular arrange- 

 ment will give an idea of the diagnoses of the genera : — 



Tarsi tomentose beneath. 

 Eyes narrow, transverse. 



Anterior tarsi with the three intermediate joints transverse. Adelium. 

 Anterior tarsi with the three intermediate joints narrow 



and obconic in the female Apasis. 



Eyes nearly round Brycopia. 



Tarsi pilose beneath. 



Prothorax emarginate at the apex Dystalica. 



Prothorax not emarginate at the apex. 



Eyes round Dinoria. 



Eyes transverse, narrow Ideinoma. 



Adelium plidgerwm. 



A. nigrum, parum nitidum ; prothorace late transverso, marginibus 

 foliaeeis, disco longitudinaliter plicato ; elytris fusco-cupreis, bre- 

 viter obovatis, interrupte striatis. 



Hob. Queensland. 



Black, slightly nitid; head irregularly punctured; two 

 transverse wrinkled impressions above the clypeus ; prothorax 

 short, the sides strongly rounded, the foliaceous margins very 

 distinct, the disk marked with fine longitudinal, irregular, 

 raised lines ; scutellum broadly triangular ; elytra of a clear 

 brownish copper-colour, shortly obovate, sharply striate, 

 the stria? interrupted, the alternate intervals between them 

 slightly raised, epipleurae with scattered punctures ; body be- 

 neath and legs dark pitchy, impunctate ; presternum and cor- 

 responding portion of propectus elevated ; antenna? black, the 

 outer joints obconical, the last ovate. Length 8 lines. 



A very distinct species, having the outline of A. auratum, 

 but at once distinguished from all other Adelia by the sculp- 

 ture of the prothorax. 



Adelium air avium. 



A. viridi-ameum, subnitidum ; prothorace transverso, marginibus 

 haud foliaeeis, disco creberrime punctato ; elytris interrupte 

 costatis. 



Hob. Darling Downs. 



Greenish bronze, rather nitid ; head and prothorax closely 

 punctured, the punctures varying in size and shape, and fre-
