716 NOTES ON AUSTRALIAN COLEOPTERA, 



a good species, closely resembling in colour and markings some 

 varieties of lutosa. My collection contains several specimens 

 intermediate in markings between those referred to above and 

 typical lutosa, and some in which the dark markings are still 

 more reduced till they consist of a mere infuscation of the front 

 of the suture and a faint shading near the lateral margin. The 

 species is common in South Australia. 



SCARITIDES. 

 Platythorax (Carenum) transversicollis, Chaud. 



Sat nitidus ; laevis ; niger, elytris violaceo-marginatis ; capite 

 lato, brevi, supra oculos unipunctato ; sulcis f rontalibus profundis 

 sat parallelis, antice fortiter divergentibus, postice quatenus oculi 

 productis ; prothorace quam longiori fere duplo latiori, antice quam 

 postice vix latiori, leviter canaliculate, angulis anticis productis, 

 posticis bene determinatis nihilominus rotundatis, basi bisinuata 

 in medio nullo modo concava ; elytris prothoraci latitudine 

 aequalibus, sat late reflexo-marginatis, antice truncatis, suturam 

 versus conjunctim late leviter concavis, tibiis anticis externe 

 tridentatis. [Long. 9, lat. 3i lines. 



The prothorax is scarcely less (as 8 to 4J) than twice as wide 

 as its length down the middle. The basal lobe (which is wide and 

 well-defined, though not much produced hindward) has its hind 

 outline evenly convex all across — not at all concave or emarginate 

 in the middle. The elytra are separately convex transversely — 

 so that if their upper outline be viewed, looking from the head 

 across the prothorax, it appears to be widely and feebly but 

 evidently concave in the middle. [It is quite possible that this 

 may be caused merely by slight immaturity.] The row of punc- 

 tures on the declivous front margin of the elytra contains 3 on 

 each side placed close together on the external half of the base, 

 and a row of punctures runs just within the lateral margin, but 

 the discoidal punctures of the elytra are entirely wanting. On the 

 anterior tibiae the teeth resemble those of Calliscapterus cam- 

 2)estris, Macl. The inferior ridge reaches the tarsus.
