CRYPTORHYNCHIDAE. 657 



ties, moderately coarsely and closely punctured. Scutellum small, greyish. 

 Elytra of the same width as thorax at the base, nearly twice its length, a 

 little broader near the hind thighs, much narrowed and nearly vertical 

 behind ; sutural striae indistinct, the others well marked, their punctation, 

 though apparently coorse, is indefinite ; the second interstices are broadly 

 costate from the base to the summit of the posterior declivity, the third 

 from the base towards the middle, these bear some pale erect scales. 



Legs similar to those of A. hopensis ; underside also nearly the same, 

 the second segment a trifle longer. 



Scape short, inserted behind the middle, gradually incrassate, just 

 reaching the front of the eye ; basal joint of funiculus slightly longer than 

 the next, third distinctly shorter, the following three still more so, .seventh 

 more transverse ; club oviform, with small apical articulations. 



Another near ally of A. australis, but the shape of the thorax, the 

 elytral sculpture, and general coloration are essentially different. The 

 pale well-developed elytral costae are distinctive. 



Length (rostrum exclusive), 3 mm. ; breadth, 1^ mm. 



Karekare, west coast of Auckland : 23rd February, 191G. My specimen 

 was caught by Mr. A. E. Brookes. 



4242. Acalles binodes sp. nov. 



Convex, compact, subovate, dull ; nigrescent, tarsi and antennae dark 

 fusco-rufous ; closely covered with overlapping, scarcely at all variegated 

 fuscous scales, and short erect setae, which are greyish on the legs. 



Rostrum a fourth shorter than thorax, arched, broad, feebly expanded 

 anteriorly, its punctation coarse and close except at the apex. Thorax a 

 third broader than lo7ig, its anterior half almost abruptly contracted, with 

 some coarse setae but not distinctly crested in front, the basal half carinate 

 along the middle, apparently coarsely and closely punctured, its ])ase a little 

 depressed and subtruncate. Scutellum absent. Elytra double the length 

 of thorax, of the same width as it is at the base and closely applied thereto, 

 their sides slightly rounded, broadest behind the middle, subvertical and 

 much narrowed posteriorly; they are very coarsely and irregularly punctate 

 and uneven, and bear on top of the declivity a pair of large, nearly hori- 

 zontal, widely distant crested nodosities. 



Legs elongate, femora grooved underneath near the extremity, tibiae 

 uncinate, tarsi rather narrow. 



Scape inserted behind the middle, short and stout, just reaching the 

 front of the eye ; basal two joints of the funicle equally elongate, the others 

 moderately short and gradually thickened ; club ovate, triarticulate. 



Underside blackish, coarsely and closely punctate, covered with tawny- 

 grey squamae, some of which form a pair of obtuse crests on the basal 

 ventral segment. Coxae about equidistant from front to rear. The elevated 

 borders of rostral canal extend to the middle of intermediate coxae. Basal 

 segment rounded in front, sinuate behind, cbviously larger than second, 

 2-4 on a lower level, together as long as fiftb. Mentum apparently narrow ; 

 palpi fully exposed. 



The nearly concolorous, dusky, overlapping squamae, conspicuous 

 posterior nodosities, and rather broad subasperate rostrum, make it necessary 

 to locate it in a section of the genus by itself. 



Tjcngth (rostrum exclusive), 3i mm. ; breadth, 2J mm.
