Australian and Tasmanian Malacodermidae. 79 



Rostrum absent. Antennae moderately serrate, passing middle of 

 elytra ; 2nd joint unusually distinct, 3rd about twice as long as wide 

 and longer than 4th, the others to 10th gradually decreasing in size. 

 Prothorax feebly transverse ; 3-areolate, apex regularly rounded, 

 sides very feebly constructed in middle, basal angles acute and some- 

 what obliquely produced. Scutelhim feebly depressed, parallel-sided, 

 apes semicircular. Elytra narrow, parallel-sided ; each quadricostate, 

 the 2nd and 4th (from suture) much more distinct than the others, 

 the interspaces with very irregular double (in many places appearing 

 single) rows of punctures. 



Length 7-8 mm.

The sutural stripe is enclosed between the second costae 

 for about one-half of its length, it then dilates so that at 

 the apex the entire surface is covered by it. The median 

 prothoracic areolet is large, continuous to base and apex, 

 and widest in middle, in each side of which there is a 

 short cariniform spur, which if continued to the sides 

 would cause the prothorax to appear 5-areolate. The 

 punctures are very irregular and are frequently conjoined, 

 both longitudinally and transversely, so that in some parts 

 there appear to be but six rows on each elytron (the two 

 outer rows being apparently always distinct). The smaller 

 longitudinal ridges are altogether absent in places, so that 

 the 1st and 3rd costae being less distinct than the 2nd 

 and 4th each elytron appears almost as if only bicostate. 

 The type is in the Macleay Museum.

(J. Black. 



Rostrum long (scarcely shorter than the prothorax), shining, finely 

 punctate at open, more noticeably towards base. Antennae stout, 

 just passing hind coxae ; 2nd joint invisible from above, 3rd consider- 

 ably longer than 4th, its ramus about two-fifths of its total length, 

 4th-9th each with the ramus about half of its total length. Prothorax 

 distinctly 7-areolate; apex much narrower than base, basal angles 

 acute and laterally produced. Scutellum transverse, apex semi- 

 circular. Elytra each with four distinct costae, the interstices with 

 almost regular double rows of transverse punctures. Abdomen with 

 penultimate segment incised almost to base. 



Length 12 mm.
