304 COLEOPTERA 



This species is extremely similar to Geranus crassus, but is only halt 

 the size, and has the front of the head between the antennie consider- 

 ably more reduced. 



Taken at Forster's Creek, by Mrs. Kelly. I have seen but a single 

 individual. 



544. G. lineiCOlliS, White. Sharp ; Ann. Mas:, ^'■it- Hist., 

 May, 1877. 6^. ////rz/.f, thorace medio fusco profundius longitudinaliter 

 impresso, elytris lateribus, antennis, prosterno vittis duabus, metaster- 

 noque lateribus nigris, tarsis geniculisque plus minusve infuscatis ; 

 antennis elongatis, intus evidenter serratis, angulis internis anterioribus 

 productis, articulis secundo et tertio brevibus, conjunctim quarto multo 

 brevioribus ; prothorace sat elongato, antrorsum evidenter angustato, 

 fortiter fere dense punctato, minus nitido ; eiytris ad humeros latiusculis, 

 apicem versus fortiter angustatis, evidenter striatis, striis fortiter punc- 

 tatis. 



Long., gh-io\ mm. 



This species is readily distinguished from its allies by the very short 

 second and third joints of the antennpe. From the specimens before me 

 I judge that the sexual differences are very slight. 



Tairua and Christchurch, and probably widely distributed. Captain 

 Broun informs me that it is "not uncommon at Tairua." 



Obs. — Acroniopus grandis ( Redtenbacher, Novara Reise, Coleopt., 

 p. 96^ will prove, I think, to be this species, or a closely allied one. 



Note. — On perusing Redtenbacher's description of his Acjvniopns 

 g7'andis, I fail to notice anything that would lead me to suppose that it 

 differed from While's G. Uneicollis, he alludes to the convex, punctulated 

 interstices, but such is exactly the sculpture of G. Uneicollis, though no 

 mention is made of this in Dr. Sharp's diagnosis. 



Protelater. 



Sharp: Ann. Mag. Nat. Hist., May, 1877. 



Forehead greatly produced between the antennee, the produced 

 portion with a slightly thickened lateral edge : these edges towards their 

 anterior part divergent, so as to form a portion of an under margin to 

 the large and deep antennal spaces ; the labriim is small, but quite 

 visible between the divergent processes at the termination of the fore- 

 head. The antenme. are slender and but litde serrate ; cliinpicce of 

 thorax very short, truncate in front, separated by a short wide notch 

 from the front angles of the prosternum. TJwrax elongate and sub- 

 cylindric, its process thick and straight; mesosternal cavity xdX\).tx broadest 

 at its hind part, with thin sharp edges which are directed downwards. 

 Middle coxce. moderately or only slightly separated. Coxal lamina 

 slightly longer outside than inwardly. Tarsi with third and fourth 

 joints with membraneous lobes. 



Though the structural characters of the following species are on the 

 whole very similar to those belonging to Geranus, yet the laterally
