Broun. — Eevision of the New Zealand Cossonidfc. 205 



Like S. nitida in form, the legs not as stout. The tibial hooks reach 

 apex of the basal tarsal joint, the minute 4th joint of the tarsi more dis- 

 tinctly visible. The scape more abruptly incrassate. Thorax rather shorter. 

 Club nearly as long as the funiculus. Occiput less swollen. Elytral striae 

 subcrenate-punctate. 



J . Length, Ih lines ; breadth, | line. 



Dunedin. One. 



Arecophaga, Broun. Man. N.Z. Coleopt., p. 533. 



Body subdepressed, elongate-subovate, moderately nitid, sparingly 

 clothed with slender but distinct hairs. 



Rostrum of about the same length as the thorax, arched, moderately 

 slender, cylindrical, indistinctly and gendy narrowed medially ; between 

 the apex and the middle with num.erous outstanding setse. Scrobes deep, 

 beginning between the middle and extremity, and extending underneath 

 to the eyes. Head globose, immersed nearly to the eyes, rounded in front, 

 distinctly marked off from the rostrum. Eyes depressed, large, their 

 greatest bulk below. Thorax about as broad as it is long, conical, abruptly 

 constricted in front, the apex appearing elevated, and emarginated in the 

 middle, its base slightly bisinuate. Scutellum distinct. Elytra slightly 

 sinuate at the base, which is a little wider than that of the thorax, gradu- 

 ally but considerably curvedly narrowed posteriorly. Scape elongate and 

 slender, flexuous, moderately subclavate at the extremity, inserted between 

 the apex and the middle and hardly attaining the eye. Funiculus laxly 

 articulated, elongate and slender, basal 2 joints nearly equally elongate, 

 3-7 rather small, the 7th largest. Club elongate - oval, quadriarticulate. 

 Femora medially dilated below, and notched near the extremity. Tibise 

 with rather small hooks, somewhat dilated medially on the inside. Tarsi 

 distinctly pseudo-tetramerous, slender, basal joint elongate, 3rd moderately 

 expanded, with a semicircular excavation so as to seem lobate. 



Underside flat. Anterior coxse less approximated than those of 

 Phloeofhagosoma, the suture between them fine but distinct. Mesosternal 

 suture subtruncate. Metasternum hardly longer than the basal 2 segments, 

 sulcate behind the middle ; 2nd ventral segment shorter than the 1st, its 

 frontal suture medially curvate. Punctuation distinct, and rather close, 

 except in front of the mesosternum. 



This genus presents a combination of peculiar characters. The sub- 

 depressed rather broad oviform body, slender arcuate setigerous rostrum, 

 and retracted head will suffice for immediate identification. The type 

 lives ^n Bhopalostylis {Areca) sapida. 



Arecophaga varia, Broun. 947. Man. N.Z. Coleopt., p. 534. (Plate XVI, 



fig. 6.) 



Variable, ranging from piceous to rufo-castaneous, the antennae and 

 tarsi rufescent. 



Rostrum asperate, indistinctly medially carinate, and with coarse 

 punctures and shallow grooves behind the point of antennal insertion, more 

 moderately punctured in front. Eyes large, extending to below the rostrum, 

 occupying nearly the whole side and front of the head, not prominent. 

 Thorax rather closely, moderately coarsely, on some parts confluently 

 punctured, quite finely and very closely in front, sometimes smooth on a 

 central lineal space along the middle. Elytra with closely punctured stria', 

 interstices more or less rugose, the sutural rather closely seriate punctate.
