416 Capt. T. Broun on new 



Ohs. As this is one of a group of species or varieties that 

 are very troublesome to identify, I have drawn up brief diag- 

 noses to lessen the difficulty. The species bear the numbers 

 908, 1297, 1299, 1301, 2194, and 2198. _ 



From P. zealandicum they are differentiated by the margins 

 of the elytra being thickened or explanate near the extremity; 

 by the longer, basally contracted rostrum of the males ; by 

 the back part of the eyes being more prominent than the 

 front ; and by the rather longer and narrower thorax. They 

 are all coarsely sculptured, and, except No. 1301, dark red. 



No. 908. — S- Scape short, quite one third shorter than 

 that of No. 903. Rostrum one third longer, closely and 

 rugosely punctured, coarsely near the eyes. Antennal inser- 

 tion a little behind tlie middle. Thorax coarsely, closely, and 

 confluently or rugosely punctured. Interstices of elytra with 

 fine serial punctures. Pubescence fine and scanty. 



No. 1297. — cJ • Rostrum nearly twice as long as that of 

 No. 903, broad, flat above, densely and rugosely punctured, 

 only a little contracted behind ; between the antennal insertion 

 and the apex there is a very distinct transverse depression. 

 Club rather short and broad. Thorax coarsely, closely, and 

 rugosely punctured. Scajye short. 



No. 1299. — S • Rostrum more slender than that of No. 908, 

 more finely sculptured ; rather shorter and distinctly broader 

 than in the female of No. 908, and with the antennal inser- 

 tion nearer the middle. Thorax not closely punctured along 

 the middle. The smooth occiput is not so well limited from 

 the sculptured portion. Scape short. 



No. 1301. — ? . Rostrum rather longer than in this sex of 

 No. 908, more finely sculptui-ed. Thorax less narrowed and 

 constricted in front, the constriction obsolete above {i. e. not 

 causing a well-marked depression there). Elytra more deeply 

 striate, the punctures closer, interstices more rugose, the 

 margins less explanate behind. Scape somewhat longer. 

 Colour darker, nearly black. 



No. 2194.— ^ . Smaller than No. 908. Elytra paler, their 

 ])unctures more separated, interstices less convex. Rostrum 

 rather shorter. Scape short. 



No. 2198. — This is distinguished from all the species of 

 this group or series by the absence of pubescence and inter- 

 stitial punctures. 



No, 1300. — Does not belong to the P. rufum series, as the 

 rostrum is not narrowed behind the middle (it is like that of 

 No. 903) and the elytral margins are not dilated near the 

 extremity.
