72 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



Head considerably longer than wide, w^idest across eyes (which 

 are at about the basal third); with a deep median line from near 

 base (where it is enlarged and almost pyriform) to clypeus, on 

 each side of which it somewhat indistinctly diverges. Antennae 

 long and thin, extending to apex of elytra; 1st joint as long as 

 the six following combined; 2nd slightly longer than the 3rd; 

 3rd slightly longer than the 4th, but shorter than the 5th: 7th- 

 9th subglobular; 10th transverse; llthobovate. Palpi long and 

 apparently (only) two-jointed, the terminal joint being unusually 

 small, and scarcely distinguishable from the true second joint, 

 Prothorax considerably longer than wide, at widest almost equa/ 

 to head across eyes, greatest width at about apical third, thence 

 obliquely and strongly decreasing in width to apex, which is 

 rounded ; sides less rapidly (and with a slight inward curve) 

 decreasing to base; very densely and finely punctate throughout; 

 each side moderately close to middle, with a fine shining carina 

 (vanishing at about the middle) curved round and joined at 

 apex and base, and from the middle of base continued for a slight 

 ■distance along the median line. Elytra distinctly longer and 

 wider than prothorax, each side of base with a triangular 

 ■emargination, apex conjointly widely emarginate, very densely 

 and finely (more coarsely than the prothorax) punctate through- 

 out. Abdomen subparallel to be3'ond the middle, the four basal 

 segments densely and rather coarsely punctate, the 5th with 

 smaller but moderately dense punctures; in ^ under surface of 

 5th very feebly emarginate at apex, the 6th deeply and triangu- 

 larly excised. Meso- and metasternum densely and rather strongly 

 punctate. Legs rather long and thin. Length 5J, to apex of 

 elytra 3; variation in length 5-6 mm. 



Hab. — Clarence River, N.S.W. 



A highly remarkable species, with head and antenna3 strongly 

 resembling those parts of many ants ; the antennae are also 

 carried much as they are by ants. It may eventually be con- 

 sidered necessary to place it in a new genus on account of the 

 position of the eyes, and the peculiar palpi, prothorax and elytra.
