618 COLEOPTERA. 



Tarsi .similar to those of I), riolascens, as are the posterior aiiiiles of the 

 thorax. 



The abnormal bulk of the last autennal joint differentiates this from 

 all the New Zealand species.

Boulderstone Creek, near Scarcliff, Canterbury ; 20th October, 1913. 

 Unique. Discovered by Mr. T. Hall. 



Group Salpingidae. 

 Salpingus Illiger. Man. N.Z. Coleopt., p. 398. 

 4188. Salpingus nigricans sp. nov. 



Oblong, slightly convex, subglabrous ; glossy acneo-niger, legs and basal 

 joints of antennae rufo-piceous, the dilated terminal three of the latter 

 darker, palpi fusco-testaceous. 



Head, including the prominent eyes, almost as broad as the thorax, 

 narrowed anteriorly, distinctly punctate, less so, but more transversely, in 

 front. Thorax cordate, not broader than long, basal margin distinct, 

 posterior angles indefinite but not rounded ; disc rather coarsely and some- 

 what rugosely i)unctured, but with an obvious smooth linear space along 

 the centre. Hcutellum broad, rounded behind. Elytra oblong, just double 

 the length of thorax, a third broader than it is ; slightly transversely 

 impressed before the middle, the suture more deeply at the base, they are 

 coarsely striate -punctate, more irregularly at the base, obsoletely behind. 

 Claws slightly thickened near the base. 



Antennae evidently shorter than the head and thorax, very finely 

 pubescent ; basal joint stout, subol)long, the next longer, 3-5 longer than 

 broad, subequal ; joints 6-8 smaller and moniliform ; ninth and tenth 

 much larger, eleventh as broad, subconical. 



[Jnderside shining black, its pubescence scanty, slender and grey. The 

 breast coarsely, the abdomen less distinctly pimctate. 



S. aterrimus (4073), also unique, is easily recognizable by its elongate 

 narrow contour, finer sculpture, and quadriarticulate club.

 Mr. T. Hall on the 5th May, 1916. 



Oroup Rhipiphoridae. 



Allocinops gen. nov. 



Antennae implanted luuir the eyes but distant from the clypeus, 

 1 1 -articulate, the basal four joints short and thick and. together, only a 

 third of the length of any of the lobes proceeding from the following ones ; 

 basal joint only slightly longer than broad, the next as long bitt just a little 

 narrower, third obtusely triangular, slightly shorter and broader than second, 

 fourth strongly transverse, as broad as the apex of the third. Head large, 

 nearly vertical in front of the antennae, subquadrate behind, with somewhat 

 deflexed, obtusely prominent hind angles. La})rum small Init quite exposed 

 between the large curved mandibles. Clypeus very short, with a definite 

 suture between it and the forehead. Eyes prominent, transverse, truncate 

 in front, without any perceptible emargination. Terminal joint of maxillary 

 palpi oblong-oval. Thorax slightly broader than long, deeply bisinuate 

 and widest at the base, gradually narrowed towards the apex which is only 

 a third as broad as the occiput, its posterior angles somewhat prolonged
