In consequence of the very distinct outer impressions each 

 apical corner of the prothorax appears to be supplied with a 

 tubercle — elongate-ovate in £, subcircular in £; in 0. vulneratus 

 .and 0. varias these tubercles are entirely absent; in 0. disci- 

 pennis they are present but much less pronounced. 



OXYTELUS DISPAR, n.sp. 



g. Wide, highly polished. Deep black, elytra feebly or not at 

 all diluted with piceous, front of antennary tubercles, the man- 

 dibles and palpi red, legs obscure testaceous. 



Head large and wide; with very distinct although not large or 

 dense punctures. Clypeus rather suddenly depressed and with a 

 few small but distinct punctures. Prothorax strongly transverse, 

 slightly narrower than head, base considerably narrower than 

 apex and gently continuously rounded; densely and rather 

 strongly punctate, the three median longitudinal impressions 

 shallow and very irregular, although sufficiently distinct; lateral 

 impressions wide and very vague, the anterior sides almost 

 perfectly flat. Elytra moderately transverse, about once and 

 one-third the width of prothorax and not much wider, sides 

 gently inflated posteriorly; densely and rather coarsely punctate 

 throughout, the punctures sharply defined except towards the 

 apex and sides, where they become more or less confluent. Apical 

 segment of abdomen lightly impressed on each side of apex. 

 Length 4|-, to apex of elytra 2^; variation in length 3-4^ mm. 



£. Differs in having a very much smaller head with much denser 

 and coarser punctures; the clypeus larger, less depressed and the 

 punctures not much smaller than elsewhere; prothorax slightly 

 wider than the head, sides not much wider at apex than at base, 

 And punctures denser and slightly stronger. 



Hab. — Hobart, Tasm. 



Close to 0. vidneratus, but colour different and punctures very 

 much coarser; punctures (especially of elytra) different from those 

 •of 0. melas.
