S. dilaticollis, the gTanules becoming obsolescent on the sides, 

 towards the coxie. Elytra (10x6 mm.) moderately produced 

 to apex, each elytron with a strong, sharp mucro at apex; base 

 gently emargmate, humeral angle with a strong, rounded tubercle; 

 punctures shallow, towards sides confluent laterally, and arranged 

 in a series of transverse grooves, suture raised, costiform at base, 

 elsewhere with a row of small granules ; second interstice with two 

 or three moderately large, isolated tubercles ; third with five similar 

 ones from base to above declivity; fourth with no tubercles; fifth 

 and sixth, and lateral interstices with tubercles small, and joined 

 across by the intrastrial ridges to form a series of parallel, trans- 

 verse rugae separated by deep sulci ; this transverse arrangement 

 also faintly traceable across the declivity. Undersurface of type 

 obscured by gum. Dimensions: 9, 16x6 mm. 



Hah. — New South Wales (?). Type in Macleay Museum. 



The only specimen I have ever seen of this interesting and dis- 

 tinct species, is the type. Probably the mucronation is a sexual 

 character; but, apart from this, the transverse rugae render the 

 species easy of identification.

9. Elongate-ovate. Black; with scanty, minute, brown squames 

 in depressions. 



Head strongly convex, front feebly bi-impressed. Rostrum wide, 

 dorsal surface much narrower than total width; external ridges 

 prominent, thick, slightly convergent basally, and running on to 

 head for a short distance; median carina evident, but slightly less 

 prominent, not extending on to head. Eyes small, rotundate. 

 Prothorax (4 x 4*75 mm.) widest in ^front of middle, not greatly 

 ampliate, rather strongly transversely convex; subapical impres- 

 sion rather indefinite; moderately closely set with rather large, 

 non-contiguous, rounded tubercles, obsolete on the sides. Elytra 

 (9 "5 X 6 mm.) not greatly widened posteriorly; base moderately 

 emarginate, humeri noduliforni, out-turned; punctures shallow, 

 not definite toAvards the sides, tending to be confluent laterally, this
