208 NEW SPECIES OF AUSTRALIAN COLEOPTERA, VIII., 



OXYTELUS TUBERCULATUS, n.sp. 



£. Moderately wide, not very highly polished. Piceous-brown, 

 head deep black, the antennary tubercles and mandibles red. 

 elytra and margins of abdomen paler than prothorax, legs pale 

 testaceous, the tibia? and tarsi slightly paler than femora. 



He r id large and wide; punctures small and sparse, but a 

 moderately large one on each side near the base; with a feeble 

 but distinct median line. Clypeus strongly and rather suddenly 

 depressed, semicircular posteriorly and almost impunctate. Pro- 

 thorax very widely transverse, exactly the width of head, sides 

 rounded and diminishing rather strongly to base; punctures 

 small and rather sparse, disc with three shallow and distinct but 

 rather vaguely defined impressions, each side on apical half with 

 a curved and very distinct impression. Elytra strongly trans- 

 verse, not much longer than prothorax and at base no wider, 

 sides inflated posteriorly; moderately closely covered with small 

 punctures, the interspaces (except for a subtriangular space about 

 the scutellum and part of the shoulders where the derm is shining) 

 densely covered with microscopic punctures. Apical segment of 

 abdomen lightly longitudinally impressed. Length 3, to apex of 

 elytra If; variation in length 2|-3i mm. 



Q. Differs in having a very much smaller head (scarcely more 

 than half the size of that of the male), with larger and denser 

 punctures, the clypeus much less depressed and distinctly 

 (although not strongly) punctate. 



Hah. — Clarence and Hawkesbury Rivei's, N.S.W. 



In general appearance moderately close to 0. dis^ennis, and 

 the punctures of the elytra somewhat similar (except that the 

 larger ones are very much larger) but differs in being consider- 

 ably narrower, elytra not entirely black (as in 0. vulneratus, they 

 are paler in the vicinity of the base and suture than elsewhere), 

 the antennary tubercles margined with red and the punctures of 

 both head and prothorax different; from 0. vulneratus it differs 

 in being very much narrower (both sexes); from 0. varius it 

 differs in having microscopic punctures densely distributed 

 amongst the ordinary ones.
