fine, impressed dots. Along the fore margin, a row of thick, 

 rather transparent horn-Hke setae is arranged (probably 

 sense cones; fig. 3a). Prostevnal processus (fig. Sh) rounded 

 at apex, with sharply bordered lateral margins, and w'ith a 

 prominent median carina which overreaches backwards the 

 rounded apical margin ; between this carina and the lateral 

 borders on either side a long broad sulcus. 



Scutelhim (fig. 3c) large, triangular, strongly pointed at 

 apex, with a lobe-like processus near either basal angle. 

 Foveolate punctures along basal cross sulcus not visible, 

 perhaps obtected by the hind margin of pronotum. Tegmina 

 twice as long as wide, widest before the middle, then gradually 

 tapering distad, narrowly rounded at apex. General colour 

 greyish-brown throughout, apical part darkened again. Sur- 

 face in the humeral region with two callosities which are more 

 transparent than the siu'roundings ; dark punctures are closely 

 arranged along all margins, much less numerous on the middle 

 area ; between them throughout the whole surface very fine, 

 impressed dots. Legs rather long and stout, of the usual shape, 

 ferrugineous. 



Measurements: — Head 0.23 mm. long, 0.27 mm. wide; 

 antennae 0.30 mm. long; pronotum 0.26 mm. long. 0.41 nun. 

 wide ; tegmen 0.52 mm. long. 0.26 mm. wide. 



One specimen from Mt. Poi, 4000 feet, which I have named 

 after its discoverer. Dr. E. Mjoberir. 



This new species comes in the key of Matthews (p. 77) neaf 

 Pt. punctatum, in that of Flach (p. 493-499) to the subgenus 

 Gillmeisteriiim. From all these European species it is dis- 

 tinguishable at once by the thick, short antennae which do 

 not reach the hind margin of pronotum in Pt. miohergi, whilst 

 overreaching it in the other species. Thus in fig. Qih—d the 

 antennae of Pt. mjdhLrcji are (at the same enlargement) ab- 

 solutely shorter than in Pt. pimctatum and Pt. reitteri, whilst 

 the former species is larger than both the others. From the 

 Ceylonese Pt. marrocephfdum Neitner differing by the shape 

 and sculpture of pronotum ; whilst in the Japanese Pt. magnum 

 Ericson (1909) the prosternal processus has no median length 

 sulcus. As to the sculpture, Pt. laicsoni from New Zealand, 

 seems to be more closely allied with my new species than any 

 other, but it has (after the description by Matthews) long, 

 slender, paler antennae and its body is broader, more ovate 

 and convex even than in Pt. punctatum , whilst Pt. mjohergi is 

 scarcely as broad and ovate as this European species.
