comes scarcely recognizable, is the emarginate apex of the 

 prothorax. The subbilol)ed fomi of the tarsi is tlie 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 de])end on them 

 alone for generic characters. The subjoined tabular an-ange- 

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



Tarsi tomentose beneath. 

 Eyes narrow, transverse. 



Anterior tarsi with the three intermediate joints transverse. Adelimn. 

 Anterior tarsi with the three iiiterniediate joints narrow 



and obconic in the female Apasis. 



Ej-^es nearly round Bnjcopiu. 



Tarsi pilose beneath. 



Prothorax emarginate at the apex Di/stalicu. 



Prothorax not emarginate at the apex. 



Eyes roimd Dinoria, 



Eyes transverse, naiTOW Licinoma. 



Adelium plicigerum. 



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

 foKaocis, disco longitudinaliter plicate ; elytris fusco-cupreis, bre- 

 viter obovatis, interrupte striatis. 



Hah. 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, 

 tlie striaj interrupted, the alternate intervals between them 

 slightly raised, epipleurte with scattered punctures ; body be- 

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

 responding portion of propectus elevated ; antennae black, the 

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



A very distinct species, liaving the outline of A. auratuniy 

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

 ture of the prothorax. 



Adelium cerarium. 



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

 liaud ibliaceis, disco crebcrrimc punctate ; elytris interrupte 

 costatis. 



Hah. Darling Downs. 



Greenish bronze, rather nitid ; head and prothorax closely 

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