Rostrum short, a little narrower than head, very little widened 

 on sides below antennse ; external ridges almost parallel ; central 

 ridge short, narrow, prominent, not extending to forehead. Head 

 convex, not flattened on sides ; front a little flattened and very 

 lightly declivous to middle of rostrum. Prothoras a little 

 broader than long (7 x 7-5 mm.), very dilatate on sides, widest 

 before middle, transversely and longitudinally convex ; middle of 

 disc rather flat ; anterior margin sinuate, the middle projecting 

 slightly over the head ; base truncate ; an obsolete transverse 

 impression across the anterior part ; longitudinal impressions of 

 sides obsolete ; median line very fine ; granules closely-set, 

 separate, small, round, unequal, unisetigerous, obsolete on sides 

 near coxre. Elytra long, narrow, not wider than prothorax 

 (14-5 X 7-5 mm.), very lightly rounded on sides, widest abou 

 middle, tapering to apex, transversely convex ; disc very lightly 

 longitudinally convex ; posterior declivity gently declivous ;' base 

 lightly and roundly emarginate ; a strong blunt tubercle at 

 shoulders ; apex rounded, without sinuosity or projections near 

 suture ; six rows of tubercles on each elytron : first short, 

 oblique, only present near soutellum : second and fourth not 

 extending to base or to posterior declivity : second consisting of 

 five widely-placed granuliform tubercles : fourth of three similar 

 ones : third and fifth (humeral rfiw) consisting of closely-placed 

 tubercles (twenty to twenty-five in a row) extending fi'om base 

 to near apex and becoming wider apart and more conical on 

 posterior declivity; tubercles of sixth stronger than tliose of 

 other rows, and not extending to base or apex ; a row of T,'ery 

 fine granules bearing short decumbent setaa between each row of 

 tubercles ; ventral segments as in S. occidentalis, SI. (male). Legs 

 long ; femora subgranulate, cylindrical ; anterior very dilatate in 

 middle, very arcuate on upper side, lower sides with a long, 

 narrow, straight, cicatrix-like ridge on anterior two-thirds ; 

 tibiie slender, four posterior ones with a few short spines on inner

Length, 22-5 ; breadth, 7-5 mm. 



Habitat. — Eraser Range. 



A single specimen. It is very closely allied to <S'. occidentalis, 

 S>1. For the same reasons as given under that species I have not 

 thought it possible for it to be ,S'. laiicoUis, Macl. 



Moloehtus tibialis, n. y). 

 Male. — Oblong-elliptical, disc of prothorax and elytra de- 

 pressed ; liead and rostrum narrow ; prothorax subquadrate, 

 closely granulate ; elytra subtiiate, the interstices irregular! 

 Llack, opaque, without scales.
