Broun. — Revision of the New Zealand Cossonidte. 169 



Female. — Rostrum of similar form, ratlier narrower and more finely 

 sculptured. Underside shining, black, the terminal 3 segments rufescent ; 

 pubescence brassy, fine but distinct ; evidently, but not coarsely or closely, 

 punctate ; the sutures between the front and intermediate coxse straight, 

 that between the basal 2 segments sinuate. Rostrum distinctly tricarinate. 

 Metasternum and basal 2 segments of nearly equal length, the former medi- 

 ally grooved behind, abdomen simple. 



The rostrum is as stout as that of Sericotrogus, but longer, narrowed 

 posteriorly, and with the antennal insertion nearer the extremity. The 

 head is shorter, and, like the eyes, more resembles Pentarthrum. Thorax 

 broader, and constricted in front. The elytra are gradually attenuated 

 posteriorly, instead of being narrowed towards the base, as in Sericotrogus, 

 and the tarsal lobes are more elongate and divergent. 



Eutassa comatum, Broun. 1748. Man. N.Z. Coleopt., p. 968. 



Rostrum and thorax dark red and moderately shining, elytra somewhat 

 fulvescent and glossy, legs and antennae infuscate red, the club and tarsi 

 slightly paler ; the vestiture yellow, slender but conspicuous, legs finely 

 pubescent, thoracic disc nearly bare. 



Rostrum and head distinctly and closely but not coarsely punctured, 

 the former more finely in front. Thorax widest just behind the middle, 

 well rounded ; disc obsoletely impressed behind, its punctuation not close, 

 rather fine, closer and finer in front, apex nearly smooth. Elytra with some- 

 what indefinite sculpture, subpunctate-striate near the suture, the punctures 

 elsewhere seriate, interstices with serial punctures and rugulose, the 3rd 

 slightly elevated behind, the apices singly rounded ; on each, between the 

 shoulder and the middle, there is a broad shallow impression. 



J . Length, If lines ; breadth, quite f line. 



Howick. One pair only. 



E. fuscicollis, sp. nov- 



Subdepressed ; except the middle of the thorax, clothed with distinct 

 yellow hairs ; thorax fuscous, elytra and rostrum slightly infuscate pitchy- 

 red, antenn* and tarsi rufescent. 



Rostrum subopaque, distinctly, rugosely, and very closely punctured ; 

 the punctuation continued to the slight swelling behind the eyes, pubescent 

 there ; occiput curvedly narrowed anteriorly, very minutely and densely 

 sculptured, and with a few fine punctures. Thorax longer than broad, 

 its sides well rounded, a good deal narrowed and contracted in front ; disc 

 unimpressed, its punctuation moderately fine, very scanty between the 

 middle and each side, close and rugose at the sides, closer and finer near the 

 smooth apical margin. Elytra elongate, subparallel to beyond the middle, 

 narrowed posteriorly, the base slightly curved towards the scutellum, apices 

 individually rounded, each slightly longitudinally impressed before the 

 middle ; they are striate-punctate ; the suture and interstices have fine 

 serial punctures and appear rugose, the 2nd from the suture thickened, 

 somewhat elevated, and sharply bent outwards at the extremity. 



Underside with distinct and moderately close punctures and yellow 

 pubescence, basal ventral segment broadly depressed, metasternum sulcate 

 behind, rostrum tricarinate. 



More robust than E. comatum ; rostriim rather longer, broader, more 

 densely sculptured, and subasperate ; the thoracic punctuation different ; 

 antennae stouter and implanted nearer the middle.
