116 Transactiotis. 



Underside black, its punctation distinct, coarser on the prosternum. 

 Metasternum very short, and, like the basal ventral segment, broadly de- 

 pressed ; the suture between the latter and the 2nd segment is straight 

 and very fine ; 3rd and 4th on an abruptly lower plane than the 2nd ; the 

 5th with an elongate apical fovea. 



Though without any basal demarcation of the smooth clypeal portion 

 of the rostrum, this species in other respects agrees structurally with the 

 typical one (2143). It is distinguishable from the others by its smaller 

 size, by the frontal contraction of the thorax, and more oviform or anteriorly 

 narrowed hind-body. 



Length (rostrum inclusive), 4 mm. ; breadth, IJ mm. 



Greymouth. I am indebted to Mr. J. H. Lewis for my specimen, found 

 amongst decaying leaves.

Subopaque, with a few slender inconspicuous brassy setae ; piceo- 

 rufous, antennae and tarsi fulvescent; 



Rostrum of about the same length as the thorax but not half its breadth, 

 moderately arched, nearly plane along the middle, dull obscure reddish, 

 with dense, very minute, granular sculpture ; its apical portion shining, 

 almost smooth, and distinctly marked off. Thorax slightly longer than 

 broad, oviform, a little contracted in front ; with a shallow groove along 

 the middle, its punctation not very deep but coarse, the intervals distinct 

 and slightly uneven, the basal margin depressed. Elytra a little broader 

 than thorax at the base, and becoming rather broader near the hind thighs, 

 they are nariov/ed and vertical behind ; moderately coarsely striate- 

 punctate ; 3rd interstices subcarinate, more distinctly near the apex. 



Tibiae shghtly flexuous, finely setose, the posterior not ciliate along the 

 inner face. Scape stout, almost glabrous. Funiculus with slender setae. 



LTnderside slightly nitid, piceo-rufous, coarsely and irregularly but not 

 closely punctate, nearly quite glabrous. Basal ventral segment depressed 

 between the coxae only, the 5th very minutely, closely, and indefinitely 

 sculptured, with a transverse impression near the apex. 



When comparing this species with S. carinatus (2556) under the micro- 

 scope I found that the rostrum of the latter has longitudinal series of coarse 

 punctures. The pale squamae in the punctures of the rostrum and thorax 

 are lacking in this species, which, moreover, has the thorax more oviform, the 

 intervals between its punctures are not flat, the elytral punctures are distinctly 

 separated, the surface is more shining, and the legs are more slender. 



Length (rostrum inclusive), 2 J mm. ; breadth, | mm. 



Mount Ngauruhoe. Mr. W. J. Guinness gathered a small bagful of leaves 

 and sent it to me in March, 1910. From amongst the leaves I picked out 

 three of this minute and interesting weevil. 



Obs. — In January, 1909, when at Waimarino, I found a specimen of *S'. 

 carinatus in which, like my type from Mount Pirongia, the posterior femora are 

 obviously fringed inwardly. This character, therefore, is not a sexual one. 



3286. Rachidiscus multinodosus sp. nov. Each idiscus Broun, Man. N.Z. 



Coleopt., p. 1477. 

 Elongate, convex, much narrowed and depressed medially ; glabrous, 

 slightly nitid, piceo-rufous, the legs and antennae pale castaneous, tarsi 

 and club fuscous, rostrum rufo-piceous.
