20 Mr. H. W. Bates on the Longicorn 



Pedes modice elongati ; femora vix incrassata. Prosternum inter 

 coxas exsertas angustum ; acetabula intermedia extus aperta. 



Founded on Cerambyx strigipennis, Westwood, which 

 White referred with doubt to Phlyctamodes, but which differs 

 in all essential points from that genus. The much shorter 

 maxillary palpi, long square muzzle, and elongated scape are 

 the most obvious structural peculiarities.

Three examples received from Mr. Fereday, of Christchurch, 

 belong undoubtedly to the same species as the type specimen 

 of Saperda tristis still preserved in the Banksian collection at 

 the British Museum. They agree also well with Redtenbacher's 

 description cited above.

Port Nicholson. I have not been able to examine the type 

 of this and the preceding species. 



Astetholea, nov. gen. 



Corpus lineare, depressum, fere glabrum. Caput breve, rotundatum, 

 exsertum, inter antennas latum, planum, post oculos gradatim 

 angnstatum, genis brevibus haud angulatis. Antennai breviter 

 pubescentes, scapo gradatim clavato, articulo tertio quam scapo 

 vel articulo quarto breviore. Oculi magni, reniformes, grosse
