Onthophagus Erichsoni. Niger, capitefere trigono, tuber culo utrin^ 

 que ante oculos posito ; thorace antice valde excavato, postice 

 convexo cornu medio lato antrorsum extenso ; elytris striato-punc- 

 tatis, pedibus, funiculoque antennarum piceis, capitulo flavescente ; 

 pedum anteriorum tibiis S-dentatis, t arsis aurantiis capillis ob- 

 sitis. Long. lin. 4^, lat. lin. 2^. 

 This insect will at some future time be considered as the type of 

 a distinct genus. 



Onthophagus picipennis, Hope. Piceus, thorace trigono, capita 



ante oculos furcato, thorace antrorsum lined elevatd conspicuo, 



punctulato ; elytris nigris nitidis, corpore infra concolori, pedibus 



rubro-piceis. Long. lin. 4J, lat. lin. 2. 



This species I have formerly received from Melville Island, and it 



is evidently the same as that taken at Port Essington. 



Onthophagus glabratus, Hope. Niger, capite integro, parilm exca- 



vato et subrugoso ; thorace Icevi sub lente subtilissime punctata, 



elytris striato-punctatis, corpore infra nigro, antennis tibiis tarsis- 



que piceis et rufo-ciliatis. Long. lin. 5, lat. lin. 2J. 



This species varies greatly in magnitude and in colouring : several 



specimens are evidently immature. 



Onthophagus discolor. Viridi-aeneus clavd antennarum fiavescenti, 

 capite integro antice excavato, postice convexo, lineis binis ele- 

 vatis transversis, und media, altera inter oculos positd ; thorace 

 viridi, nitido sub lente punctulato ; elytris atro-viridibus, striata- 

 punctatis, punctis fortiter impressis, corpore infra concolori. 

 Long. lin. 3, lat. lin. 1^. 

 The above species of Onthophagus are all from Port Essington ; 

 and I may here mention that there are in my collection tvi^enty-four 

 species from other parts of New Holland which have hitherto re- 

 mained un described. 



Tessarodon piceum, Hope. Affine Scarabseo Novae Hollandise, Fab. 

 Piceum, capite bituberculato, thorace inermi punctulato elytrisque 

 striato-punctatis et subscabrosis ; corpore infra rufo-piceo, pedi- 

 bus ciliatis. Long. lin. 2^, lat. lin. 1^. 

 This appears to be an insect closely allied to the Novce Hollandia 

 of Fabricius, from which it differs in several points. 



Copris glabricollis, Hope. Niger, capitefere trigono, parilm emar- 

 ginato vix subrugoso, thorace laevi nitido, postice lined transversa 

 punctorum satis notato, elytris striato-punctatis, punctis fortiter 

 impressis : corpore infrcL nigro capitulo antennarum flavescente, 

 funiculo autem et tibiis rufo-ciliatis. Long. lin. 5, lat. lin. 2^. 

 True Copris in New Holland are rare ; from Melville Island I pos- 

 sess three species, which I have named steriocerus, corniger and insu- 

 laris. The insect described above is an additional one. They are 

 all remarkable for having the punctures apparent on each side of 

 the elytra, and therefore are closely allied to several of the African 

 Coprida, such as C. Orion of De Jean, and also to Copris Bengal- 

 ensis of Hope. 



Msechidius rufus, Hope. Rufus, capite parilm emarginato subrc" 

 flexo, thorace fere semicirculari, lateribus extrorsum convexis, an-
