AnthribidiP of New ZeahauL 427 



Sent from Auckland and Tairua by Captain Broun and 

 Mr. Lawson. 



Ohs. I. This species varies much in size and in the develop- 

 ment of the antennse, and also a good deal in colour. The 

 specimens which I consider to be females are small, and the 

 antenna3 are shorter and more slender than in the other sex ; 

 the rostrum also varies much in length. 



Obs. II. This species in general structure much resembles 

 Tropideres niveirostris, the antennfe of the two species being 

 verj similar. The rostrum, however, is much more produced 

 in A. Brouni] and its form, as well as that of the head, is dif- 

 ferent; the eyes are more, entirely lateral in A. Brouni, 

 and the antennal cavities are different in form. Trojnderes 

 septcola, however, in all these respects appears to approach 

 Anthribus Brouni more closely ; so that the generic qualirica- 

 tions (if I may use this term) of A. Brouni must be considered 

 doubtful. 



Anthribus bidlatus, n. sp. 



A. eapite breviter rostrato, ociilis prominiilis, oblongus, variegato- 

 tomentosus. antennis pedibusqiie testaceis ; eljtris pone medium 

 quadrifasciculatis ; pygidio quadrato. Long. eorp. 2| m. m. 



Antennae formed much as in A. Brouni, but with the joints 

 of the club more laxly articulated, and with the eighth joint 

 scarcely differing from the seventh. Rostrum similar in form 

 to that of A. Bi'oum, but yet much shorter, so that the posterior 

 margin of the antennal cavities is near to, though quite di- 

 stinctly separated from, the eye ; it bears two patches of dense 

 white pubescence, which are conjoined behind though diver- 

 gent in front. Thoracic carina distinctly sinuate on each side, 

 and without any angle, and very gradually bent forwards. 

 Elytra rather densely clothed, the shoulders and apex paler 

 than the other parts, just above their declivity with a dense 

 pencil of dark hairs, and with another but less distinct pencil 

 just behind the middle ; pygidium yellowish, quadrate ; ventral 

 plate of apical segment of hind body prominent and peculiarly 

 flattened in the middle ; basal joint of hind tarsus scarcely 

 longer than second and third together. 



Tairua : a single individual sent by Captain Broun. I 

 believe it to be a male ; and it is very probable that the 

 peculiar form of the apex of the abdomen is peculiar to that 

 sex. 



Obs. Though much resembling the Anthribus Brouni, the 

 A. bullatus is readily distinguished therefrom by the short 

 broad rostrum and by the waved thoracic carina.
