Ateratocerus, gen.nov. 



Palpi maxillares ut Cyclomeloe ; antennae robustae, articulis 



3-11 sat fortiter compressis ; oculi ovales transversi minus 



fortiter granulati ; acetabula antica postice late aperta ; 



metasternum elongatum ; ungniculi appendiculati ; corpus 



elongato-oblongum ; segmento ventrali apicali postice fortiter 



multispinoso. 



It is rather difficult to say where this genus should be placed 



in Lacordaire's arrangement, but perhaps it would be most at 



home among the " Australicites." It differs from Calomela in its 



elongate more fragile facies, and in its claws not bifid but appen- 



diculate. The stout unicolorous metallic antennae, colouring, and 



style of markings of the species before me are suggestive of 



Phyllocharis, but the anterior coxae widely open behind separate 



it at once from that genus. 



Ateratocerus intricatus, sp.nov. 



Elongato-oblongus ; nitidus : Isete rufus ; antennis nigro- 

 violaceis, femoribus tibiisqne plus minus piceo-violaceo- 

 micantibus, elytris intricate piceo maculatis fasciatisque ; 

 capite Isevigato iutei- oculos pi'ofunde impresso, vertice sub- 

 tiliter longitudinaliter canaliculato ; prothorace quam 

 longiori plus duplo latiori, vix perspicue punctulato, antici 

 angustato, lateribus leviter convexis, angulis sat acutis, base 

 leviter convexa, margine antico fortiter concavo ; elytris pone 

 basin latera versus l^ate transversim impressis, seriatim 

 punctulatis, puncturis nisi antice suturam versus et in 

 impressione transversa vix perspicuis.

 The basal joint of the antennae is short and piriform, joint 2 

 much smaller still, 3 as long as 1 and scarcely compressed, 4 

 scarcely different from 3, 5-8 decidedly and increasingly com- 

 pressed, 9-11 each almost identical with 8 except that 11 bears at 

 its apex a small narrower piece which has all the appearance of a 



I2th joint. The piceous markings on the elvtra are quite similar
