First joint of antennse considerably thicker than the following joints, 2nd 

 rather shorter than Ist, and considerably stouter than 3rd, and also considerably 

 longer than it, 4th longer than 3rd, 4 — 11 all slender and elongate, but the apical 

 joints are larger than the intermediate, 11th longer than 10th. Head with the 

 eyes rather large, the space between them elevated, and longitudinally divided down 

 the middle. Thorax almost impunctate. Elyti-a with ten rows of coarse punctures, 

 the interstices between them being slightly elevated, especially behind. The ex- 

 tremity of the pjgidium slightly pi-ojecting beyond the elytra ; uuder-surface almost 

 impunctate. 



This species has becu sent me both from Auckland by Mr. Lawson 

 and from Tairua by Captain Broun ; the latter gentleman indicated 

 some of his specimens as being found on one of the tree ferns {Cijatliea 

 dealhata) . 



AENOMUS,* nov. gen. {Chrysomelidarum) . 



Goxce anteriores distantes. 



AntenncB elongatce, -fiUformes, hasi distantes. 



Caput subinsertum, oculis integris. 



Ehjtra ampla, tliorace latiora, fygidium ohtectentia. 



Scutellum conspicuum, parvum. 



The interesting insect for which I propose this generic name, is 

 somewhat allied to Stylosomus ; and would apparently, in Chapuis' 

 arrangement, indicate a fresh group, allied to the StyJosomites, and 

 placed at the beginning of the Cryptocepluilides. It differs from Sty- 

 losomus, by the widely separated coxa?, by the ample elytra which give 

 the insect a different form, and by the visible scutellum. The group 

 Stylosomites consists of the single Mediterranean genus Stylosomus, 

 and by altering its formula somewhat, the New Zealand genus might 

 be included in it. 



Aexomfs Beouni, n. sp. 



Ferrugineus, capite peetoreque ceneis, antennis apice fuscis ; dense 

 punctatus. Long. corp. 2^ — 3 mm. 



Fern, ahdomine apice fovea magna. 



Antennse rather long, slender, the four or five basal joints reddish, the others 

 infuscate. Head brassy-green, very densely punctured. Thorax very transverse, but 

 a good deal narrower tlian the elytra, reddish, more or less tinged with brassy, ex- 

 tremely densely and rather finely punctured, the interstices being excessively small ; 

 the sides and base finely margined. Scutellum small, black and impunctate. Elytra 

 very densely and rather coarsely punctured, with a small but distinct, sinning, 

 humeral callus. Legs elongate, red, the tarsi moderately stout and long.
