360 MISCELLANEA ENTOMOLOGICA, 



Calloodes Mastersii. 

 Long. 8 lin. 



Argenteo-viridis nitidissimus, capite dense punctulato, clypeo 

 rotundato in mare angulato, thorace leviter punctulato, 

 elytris leviter punctulato-striatis, pedibus pallide rufis, cor- 

 pora subtus parce albido-piloso, mesosterno minime producfco 

 obtuso, pygidio acuducto apice subbarbato. 



Hab. Port Denison. 



The remaining genus Repsimus will by this arrangement 

 comprise only three species — ceneus Fab. found all over New 

 South Wales and Queensland, manicatus Swartz. of equally wide 

 range, and purpureipes mihi. from Grayndah, Queensland. 



The genus Bolboceras Kirby is well represented in Australia. 

 The species described, however, fall far short of the numbers to 

 be found in collections. Mr. Bainbridge, and subsequently 

 Professor Westwood, described some years ago a number of them, 

 but almost exclusively from Western Australia. The species of 

 South Australia seem to have been quite overlooked ; and the 

 same may be said of those of the North, with the exception of a 

 few in Mr. Hope's collection from Port Essington, and of three 

 described by me of late years, from Port Denison and Gayndah. 



I shall commence my descriptions of the new species with 

 those which have two or more prominent horns on the head in 

 the male.

I have only the male of this species. The head is furnished in 



front with a transverse elevation, terminating in three strong
