Black ; head red, with a large black spot in front on the disc • 

 prothorax shining, the posterior angles slightly rounded ; elytra 

 black, not tinged with blue. 



Lithgow, New South Wales ; Melbourne, Victorian Alps ; 

 Lottah, Gould's Country, Port Frederick, Hobart, Tasmania. 



The latter form has usually been regarded as distinct 

 from Creophilus erythocephalus, but after an examination of a 

 large number of specimens from all parts of the country I have 

 come to the conclusion that it can only be regarded as a variety. 

 The most noticeable differences, namely the colour of the elytra 

 and the slightly -rounded hinder angles of the prothorax, are 

 characters of little importance, and in this instance of no geo- 

 graphical significance, as both the typical form and the variety are 

 sometimes found in the same locality. A series of specimens 

 which I have received from Lithgow, in the Blue Mountains, 

 contains both black and blue forms as well as several exhibitino' 

 intermediate stages ; of these one with black elytra (var. lanio) 

 has the hinder thoracic angles as strongly rounded as the typical 

 form, a fact, I think, in itself sufficient evidence of the specific 

 identity of the two forms. 



The New Zealand form C oculatus, has been recorded as Aus- 

 tralian by M. Fauvel, but as the locality is vaguely stated to be 

 Eastern Australia and no special reference is made to it, I think 

 more evidence is necessary before admitting the species into 

 our lists. 



35. CoLONiA, gen. nov. 



Mentum broadly transverse, the anterior margin straight. 

 Ligula very small. Maxillary palpi moderately long, the basal 

 joint very short, the 4th joint acuminate, about as long as the 2nd, 

 distinctly longer than the 3rd. Labial palpi like the maxillary in 

 form, the last joint much longer than the 2nd. Maxillae with the 

 lobes distinct, the internal one shorter than the other and ciliated 

 internally ; external lobe narrowed at the base, ciliated above.
