530 STUDIES IN AUSTRALIAN ENTOMOLOGY, NO. XIV., 



shagreened, hardly broader than long (1-2 x 1-3 mm.), constricted 

 and cylindrical anteriorly and posteriorly; disc strongly and 

 roundly tumid. Prosternal episterna roughly shagreened like the 

 pronotum, dividing line between these parts (lateral border) 

 indistinct. Elytra much wider than head (4x2*2 mm.); derm 

 closely punctate, the puncturation becoming stronger from apex 

 to base, much more coarse on light-coloured basal parts. Length 

 7, breadth 2*2 mm. 



Hab.—Q. : Cairns District (Dodd). Sent to me by Mr. F. P. 

 Dodd from Kuranda on the Cairns Railway. 



This species is isolated by its small size, narrow head, globular 

 thorax, densely punctate elytra, without undulate sculpture, and 

 without any lightly coloured fascia across middle of disc. 



CARABIDiE. 



Tribe PLATYSMATINI. 



Group Morionides. 



Lacordaire (1854) regarded the ]Morionides as a distinct tribe, 

 as also did Horn (1881); but Chaudoir, when he monographed 

 the Morionides in 1880, looked upon them as forming part of the 

 great carabidous tribe Platysmatini."^' 



Genus M o r i o. 



Following Chaudoir the Australian species of Mario may be 

 divided into two groups as under : — 



i. Prothorax with sides bisetose. Mentum with lobes sinuate on anterior 

 part of external side 1. M.longirptiuus,V\xiz. 



ii. Prothorax with sides plurisetose. Mentum with external side of lobes 

 not sinuate 2. 21. australU, QB,?,iQh\.

*"Les insectes dont nous allons nous occuper font .... partie du 

 grand groupe Feroniens." Bull. Mose. 1880, p. 317. This supports the 

 opinion expressed by me (These Proceedings (2) ix. p. 409) when I did not 

 know Chaudoir's views on the taxonomical value and position of the 

 Morionides.
