elytra moderately strongly and sparingly punctured for the basal 

 two-thirds, scarcely punctate posteriorly. 



Head impunctate. Antennae in both sexes more than twice as 

 long as the body, rather closely pubescent, gradually attenuated 

 towards the extremity ; the first joint very robust, and thickened 

 towards the apex, where it is somewhat produced outwardly and 

 obliquely cut ofi" above ; 2nd joint more than one and a-half 

 times as long as the first ; apical joint about as long as the two 

 preceding joints together. Pro thorax transverse, with two im- 

 pressed lines near the anterior margin, and two near the posterior 

 margin, the former interrupted in the middle, the punctuation 

 confined to the disc on either side of the middle. Scutellum 

 rounded behind, impunctate. Elytra considerably narrowed pos- 

 teriorly, rounded at the apex, sparingly and moderately strongly 

 punctured near the base, the punctuation gradually decreasing in 

 strength posteriorly, effaced beyond the basal two-thirds. Under- 

 side densely clothed with umber-brown pubescence like the upper 

 surface, except the head, prosternum, and the inner side of the 

 anterior femora, which are pitchy and scantily furnished with fine 

 grey pubescence. Legs with the femora rather closely pubescent, 

 the pubescence inclining to grey above ; tibiae with dense outstand- 

 ing pile towards the apex. Length, ^ 29 mm. ; 2 32 mm. 



Cloncurry, Queensland. 



A very fine and distinct species quite unlike any of those known 

 to me, but evidently belonging to the Monohammus fistulator 

 group. The sexes only appear to differ in the length of the 

 antennae, those of the male being somewhat longer than those of 

 the other sex. 



Monohammus artius, sp.n. 



Elongate-ovate, densely covered with ashy-grey pubescence ; 

 head with a few scattered punctures in front between the antennae, 

 and a few on each side of the median line behind the eyes ; pro- 

 thorax with the lateral spines strongly produced, rather blunt ; 

 elytra sparinglj' punctured throughout.
