Broux. — Revision of the New Zealand CossonidiX". 179 



thorax. Legs stout and elongate ; femora swollen and obtusely angulate 

 below ; tibise moderately and gradually expanded, their hooks rather small 

 but quite distinct, with a slender spiniform process at the inner extremity. 

 Tarsi moderately narrow, terminal joint as long as the basal 3 combined, 

 3rd moderately expanded and subbilobed, claws small. 



The form most nearly resembles that of Baorhopalus, the thorax par- 

 ticularly. The rostrum is thick vertically, and the scape unusually in- 

 crassate towards the extremity. There is no approximate genus amongst 

 the Pentarthrides. 



Glyphoramphus rarus, Broun. 1735. Man. N.Z. Coleopt., p. 971. 



Nitid, piceo-rufous tinged with castaneous, antenna^ pale ferruginous. 



Head and rostrum densely and very minutely sculptured ; the punctures 

 on the head are rather fine, but not close, and gradually become finer and 

 fewer towards the front of the rostrum. Thorax distinctly longitudinally 

 impressed, moderately finely and not closely punctate, the apex raised and 

 nearly smooth. Elytra slightly broadly impressed before and behind the 

 middle, regularly and moderately finely striate-punctate, striate behind : 

 interstices finely seriate punctate and rugose, the 3rd and the suture elevated 

 and sharply bent at the extremity. 



3 . Length, IJ lines ; breadth, f line. 



Mount Egmont. Unique. 



Belka, gen. nov. 



Body fusiform, moderately convex, evidently clothed with decumbent 

 elongate yellow pubescence. 



Rostrum rather shorter than thorax, subparallel, slightly narrowed near 

 the base, cylindric, half the width of the head, and bearing many fine but 

 elongate setae along its sides ; these are most easily seen from underneath. 

 Scrobes prolonged to the inner and lower part of the eyes, their upper margins 

 sharply defined there. Scape inserted behind the middle, attaining the 

 centre of the eye, elongate, only moderately slender. Funiculus rather 

 stouter than the scape, 2nd joint longer than 3rd, joints 3-5 become shorter. 

 Club ovate. Head rather short, occiput strongly globose underneath, 

 slightly narrowed but not perceptibly marked off in front. Eyes slightly 

 prominent, moderately small, almost transversely oval. Thorax longer 

 than broad, widest behind the middle, well rounded there, a good deal 

 narrowed and constricted in front. Scutellum small. Elytra broader than 

 thorax at the base, subparallel, narrowed behind, base slightly biarcuate, 

 apices not distinctly rounded separately. Legs stout, femora subclavate ; 

 tibipe uncinate ; penultimate tarsal joint slightly dilated, concave above, 

 entire below, terminal rather thick, with small claws. 



It would be absurd to leave the type of this genus with Pentarthrum. 

 The rostrum is like that of the female Pentarthnim^ (903) in length, but is 

 slightly stouter, and quite perceptibly narrowed near the base. The eyes 

 are distinctly smaller and more transversal. The scutellum is smaller. 

 The scape cannot reach the back of the eye. The metasternum is. shorter, 

 ^^ ith a very short groove behind. The basal 2 ventral segments are unim- 

 pressed, but their suture is well marked and sinuate. The rostrum under- 

 neath has 2 sharply impressed grooves. The more robust body and legs, 

 different antennal insertion, and entirely dift'erent vestiture, &c.. distinguish 

 it from Attarus, near which it should be placed.
