sparingly clothed with pale-brown and somewhat fulvescent depressed 

 squamae, and numerous outstanding elongate infuscate setae. 



Rostrum slightly and gradually narrowed medially, fully a third shorter 

 than thorax, very little arched, smooth but not perceptibly carinate along 

 the middle, finely punctate in front. Thorax slightly longer than broad, 

 widest and moderately rounded behind the middle, more, yet gradually, 

 narrowed anteriorly than behind, the base bisinuate ; it is coarsely and 

 closely punctured, broadly impressed along the middle, with a very slender 

 carina along the centre of the impression. Elytra cordate, of about the same 

 width as the thorax at the base, m ich broader and rounded at the m'ddle, 

 a good deal contracted and nearly vertical behind ; they are very coarsely 

 and irregalarly striate-punctate, some of the punctures coalesce and form 

 deep abbreviated grooves, the sutural striae are more distinct behind ; 3rd 

 interstices elevated from the base to the middle, less so behind, with, on 

 each, a nodosity just below the top of the posterior declivity. 



Scape inserted immediately behind the middle and attaining the front 

 of the eye, gradually thickened ; 2nd joint of funiculus nearly as long as 

 but much more slender than the basal, joints 3-6 subquadrate, 7th rather 

 larger than 6th ; club ovate, densely pubescent, triarticulate, basal joint 

 largest. Legs stout and elongate. Tarsi rather slender, penultimate joint 

 a little dilated, with short lobes. 



Instead of being regularly striate-j^unctate alongside the suture of the 

 elytra as in 2967, 0. latisidcatus, the sculpture on some spots seems like deep 

 interrupted grooves, the punctures themselves are coarser, the thoracic 

 impression is less sulciform, and the scales are more scanty. 



The longitudinal thoracic impression, with its fine central carina, is 

 characteristic of the genus. 



Length (rostrum exclusive), 2| mm. ; breadth, quite 1 mm. 



Erua, near Waimarino. I found one in January, 1910, and obtained 

 another in a bagful of decaying leaves sent to me by Mr. W. J. Guinness 

 in April. 



Xenacalles gen. no v. 



Body squamose, subfusiform. Head immersed up to the eyes. Thorax 

 conical, its base truncate, with ocular lobes. Scutellum distinct. Elytra 

 rather broader than thorax at the base, elongate-cordate, somewhat laterally 

 compressed behind. 



Rostrum about as long as thorax, subparallel, nioderately arched. 

 Scrobes lateral, deep, extending from the middle to the eyes. Scape in- 

 serted at or near the middle, according to sex ; it attains the eye. Funi- 

 culus 7-articulate, longer than the scape, 2nd joint about as long as the 

 1st, 3rd and 4th rather longer than broad, joints 5-7 moniliform, increas- 

 ing in width. Club well marked, ovate, triarticulate, basal joint largest. 

 Eyes large, subdepressed, subrotundate. Femora elongate, simple. Tibiae 

 uncinate. Tarsi rather slender ; their penultimate joint moderately ex- 

 panded and bilobed, their soles hairy, not at all sponge-like. 



Pectoral canal profound, extending to the middle of the intermediate 

 cOxae in X. triangidatus, and to the front of the metasternum in X. squarni- 

 ventris, bounded behind by the raised margins of the mesosternum, quite 

 cavernous there. Anterior coxae placed at the base of the prosternum. 

 Metasternum not longer than the 2nd ventral segment; the 1st angulate 

 in front, a third longer than 2nd, its hind suture straight ; 3rd and 4th to- 

 gether evidently longer than 2nd ; the 5th not quite as long as the basal.
