 joint longest and acuminate. Thorax broader than long, rounded 

 in front, widened behind, the anterior angles obtuse, the posterior 

 acute, 5-areolate, the discal areolat narrow and extending to the 

 apex. Elytra of the usual quad ricos bate sculpture, and considerably

38. Xylobanus ater. 



This species might be more properly placed in another genus. 

 The colour is entirely opaque black. The head is small, and shows 

 distinctly in front of the thorax, the eyes are very prominent, 

 the antennae are strongly serrated, the third joint scarcely longer 

 than the fourth. The thorax is transverse, the apex almost 

 truncate, the sides widening towards the base, the posterior 

 angles very acute, the discal areolet raised and well marked, 

 the other areolets indistinct, but their positions marked with 

 depressions, and the colour is of a somewhat nitid black. The elytra 

 are strongly quadricostate, with the transverse lines also distinct. 

 The legs rather slight. 



Length, 3 lines. 



Hah. — Barron River.

 the discal areolet joined to the anterior margin by a carina, the
