OF NEW ZEALAND. 619 



Arnomus. 



Sharp; Ent. Mon. Mag., October, 1876. 



Coxa anteriores distantes. Antenna elongatae filiformes, basi distan- 

 tes. Caput subinsertum, oculis integris. Elytra ampla, thorace latiora, 

 pygidium obtectentia. 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 Stylosomites, and placed 

 at the beginning of the Cryptocephalidce. It differs from Stylosomus, by 

 the widely separated coxae, 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. 



1086. A. brouni, Sharp ; Ent. Mon. Mag., October, 1876. Ferru- 

 gineus, capite pectoreque aeneis, antennis apice fuscis ; dense punctatus. 



Long. Corp., 2^-3 mm. 



Fern, abdomine apice fovea magna. 



Antenna rather long, slender, the four or five basal joints reddish, the 

 i others infuscate. Head brassy-green, very densely punctured. Thorax 

 very transverse, but a good deal narrower than the elytra, reddish, more 

 i or less tinged with brassy, extremely densely and rather finely punc- 

 tured, 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 shining humeral 

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



The species apparently varies a good deal in colour ; especially as to 

 ! ;he extent and distinctness of the brassy tinge. 



Five specimens of this very interesting species have been recently 

 isent me from Tairuaby Captain Broun, whose persevering researches are 

 | wringing to light a remarkable number of important New Zealand insects, 

 ind in whose honour I have named it. 



Alema. 



Sharp ; Ent. Mon. Mag., October, 1876. 



Caput exsertum, ore haud inflexo. Antenna filiformes, ad insertio- 

 jiem approximates. Thorax coleopteris duplo angustior, lateribus vix 

 1 narginatis. Femora posteriora incrassata. Acetabula antica occlusa. 

 Antenna eleven-jointed, inserted near one another on the middle of 



he head. Thorax scarcely broader than the head, quadrate, but con- 

 ! ;tricted behind the middle. Elytra without epipleurae. All the coxa 

 )ut slightly separated ; there is no projection of the process between the 



ront ones. The legs are rather long and slender, the tibia without spurs 

 !)r grooves ; the first joint of the tarsi twice as long as the second ; third 



nuch broader than the others, bilobed, fourth rather short, not so long
