Long. Corp., 3 J mm. 



Head with a large and well-marked line between the antenna. 

 Thorax impunctate, with the lateral and front margins entire. Elytra 

 with three deep entire striee, and an abbreviated one at the extremity 

 on the inner side of these, impunctate. Pygidiuvi and propygidium 

 rather coarsely punctured. Front tibice with four, middle with three, 

 hind with two, sharp teeth. 



This species is extremely closely allied to our European P. frontale 

 and P. depressuDi, and in form is about intermediate between the two. 

 It may, however, be readily distinguished from them by the denticles of 

 the tibi;©, and the want of lateral punctation on the thorax. 



This species is due to Mr. Lawson, who sent it from Auckland. 



Note. — I found three specimens amongst vegetable rubbish in tlie 

 Auckland Domain, and believe it confines itself to that locaUty.
