but from that point of view is very manifest, especially in the 

 middle. The species is very distinct from any other known to 

 me. From those species which it most resembles superficially its 

 strongly bicarinate head in combination with non-metallio 

 surface separate it widely. 



N. Queensland (sent by the late Mr. Cowley), 



O. fitzroyensis, sp. nov. Mas. Sat latus ; supra glaber ; subtus 

 sparsissime fulvo-hirtus; minus nitidus, subtiliter coriaceus ; 

 piceus vel niger, leviter vel vix senescens, tarsis palpis 

 antennisque ferrugineis, harum clava testacea ; clypeo sat 

 fortiter punctulato, antice rotundato ; sutura clypeali leviter 

 carinata, capite pone clypeum sparsius subtilius punctulato 

 et inter oculos bicornuto ; oculis sat angustis, leviter con- 

 vexis, vix manifesto granulatis ; prothorace quam longiori 

 ut 17 ad 11 latiori, supra crebrius subtilissime punctulato, 

 antice a medio oblique concavo-retuso, supra partem retusam 

 in medio vix gibbo, utrinque latus versus foveolato, lateribus 

 ante medium haud (pone medium subfortiter) sinuatis ; 

 angulis anbicis subacutis posticis rotundato-obtusis ; basi 

 angustissime subplanata ; elytris crenulato-striatis, crenulis 

 vix punctiformibus quam striae vix latioribus, interstitiis 

 crebrius subobsolete punctulatis : pygidio sparsim obsolete 

 (metasterno sparsim subtiliter, latera versus sparsim grosse) 

 punctulato ; pedibus anticis minus elongatis ; tarsorum 

 posticorum articulo apicali subtus breviter acuminato- 

 producto, unguiculis sat magnis, fortiter curvatis. 



Femina (?) quam mas magis opaca, clypeo antice leviter sub- 

 sinuato ; capite pone clypeum magis crebre punctulato, 

 inermi ; pronoto antice vix perspicue retuso, in medio etiam 

 minus gibbo, vix perspicue punctulato ; elytris minus fortiter 

 striatis, interstitiis planis. Long., 3^L; lat., 2i 1, 



The male described above and the insect described doubtfully 

 as its female are in the S. Australian Museum among the relics 

 of the ill-fated Calv^ert exploring expedition in N. VV . Australia. 

 The two were taken at the junction of the Fitzroy and Margaret 

 Rivers, apparently in company. I have no serious doubt of their 

 being one species, but ifc is to be noted that I know no other 

 Australian Onthophagus in which the front of the pronotum is 

 strongly retuse in the male and all but absolutely nou-retuse in 

 the female. The species is near O Kingi, Har., which, inter 

 alia, is considerably larger, is devoid of coarse puncturation on 

 the metasternum, and has much wider eyes. O. queenslandicus is 

 another ally, but inter alia, its head is quite strongly bicarinate.
