structure of the antennae is totally, different to that ordina- 

 rily prevailing among the PaussidcBy the full number of joints 

 of the antennae still being in existence, although the second 

 one is very small and rudimentary. All the other joints are 

 quite normally developed, only showing a slight tendency of 

 being laterally compressed. 



Also in regard to the legs, this form seems to show pri- 

 mitivity, the tibise being very little dilated and the tarsi 

 simple. 



The species reminds one slightly of the Asiatic genus 

 Protopaussus Gestro, although the shape of prothorax is 

 quite different. 



Like that genus, the antennae have the full number of 

 joints, which are only slightly compressed. It falls natur- 

 ally within the group Protopaussidce Gestro, representing 

 the most primitive forms of the family PaussidcE, the relation- 

 ship of which to the Carabidce now seems to be beyond doubt. 



In JuNK & Schenkltng's Coleopt. Catalogus 1900 Gestro 

 places this form among the Cerapterini, which should be 

 rectified. 



One single specimen taken by the author under a log at 

 Evelyne, Atherton-Herberton tableland, North Queensland, 

 April 1913. 



2. Arthropterus cerapteroides n. sp. (Fig. 11). — Bril- 

 liant dark reddish-brown, with very fine punctures. Eyes 

 large and prominent, head fairly broad, slightly impressed 

 between the eyes, with scattered punctures, posterior angles 

 prominent and clothed with stiff hairs; antennae very large 

 and broad, slightly increasing in width from the second 

 to the ninth, each of these joints at least five times as 

 broad as long, their angles sharply produced, the last joint 

 not quite so broad, rounded towards the apex, all the joints 

 provided with short hairs. Prothorax distinctly broader than 

 long, the anterior angles quite rounded, the anterior margin 

 slightly emarginated, subcordiform, suddenly tapering towards 

 the base, the breadth there about equal to the length, on the 

 disc two small impressions, a median line lightly impressed 

 in the middle; finely ciliated. Legs extremely broad, reraind- 

 ing one of certain species of the genus Cerapter^s, anterior 

 tibiae distinctly excised at the apex, rufous, partly infuscated.
