"P. trivittatus. Blackish-brown with numerous scale-like hairs. 



Inhabits North-west Territory. 



Body blackish -brown, with numerous robust hairs almost resembling 

 scales, which are longer in three yellowish metallic thoracic vittae of 

 which the lateral ones are broader and terminate in a spot on the hum- 

 erus; the vittae and spot are pale brownish cinereous; antennae rufous; 

 elytra with large costal spots, interstitial lines obsoletely alternating 

 with blackish and pale brown-cinereous; suture behind the middle also 

 pale brown-cinereous; thighs beneath near the tip emarginate; anterior 

 tibiae a little incurved at tip.

 1.5-3.5 mm. 



Black or dark brownish red, elongate oval, usually densely pubescent 

 with scales and hairs. Legs black or reddish-black. 



Head densely closely pubescent with long slender hairs the pube- 

 scence extending some distance down the beak, especially dense on the 

 front which between the eyes is narrower than the width of a single eye; 

 beak with a smooth flat carina or keel, possessing above the antennal 

 groove a long shallow narrow impression, sides and tip of beak more or 

 less sparsely finely punctured, with a few long slender hairs. Some of 

 the hairs on the head above and behind the eyes are broader. Eyes 

 elongate oval, without a fovea behind; antennal groove deep, strongly 

 sloping towards the base of the eyes; antenna rufous or reddish testa- 

 ceous, scape reaching the margin of the eye, at least as long as the first 

 six joints of the funicle, first funicular joint stout, one-half lunger than 

 the second which is distinctly lunger than the third, club elongate-oval, 

 darker and finely densely pubescent, more or less pointed at tip. 



Prothorax narrowest anteriorly, strongly widely rounded near the 

 middle, but nowhere as wide as the elytra at their base; the dorsum with 

 a narrow light median longitudinal line bordered on each side by a much 

 wider dark line or band, and beyond these on the edge the scales are 

 again light, the lower part of the sides and part of the venter with dark 

 scales; the side band of light scales extends back onto the elytra near the 

 humeri and in one specimen partially covers it, in the others examined
