which is truncate ; punctures much as on head. Elytra much wider than pro- 

 thorax and about twice as long, sides gently rounded ; punctures slightly larger, 

 denser, and more angular than on prothorax. Abdomen long, four segments and 

 base of another with characteristic sculpture of the genus ; anal styles very long 

 and thin. Front femora stout, obtusely dentate; front tibiae rather short, 

 strongly dilated to apex, four basal joints of front tarsi large and lopsided; 

 other legs rather long and thin. Length, 5-6 mm.

Two specimens are paler than the others, with the abdomen not much darker 

 than the prothorax, on the others the abdomen (except the tips of the segments) 

 is almost black. The darker specimens have the four basal joints of the front 

 tarsi larger and more conspicuously lopsided than on the others and are probably 

 males ; I have been unable to find any other characters that appear to be sexual. 

 The dark parts of the elytra vary in intensity, but in general may be considered 

 as forming a dark U on each elytron (from each shoulder a pale vitta extends 

 about to the middle on two specimens, almost to the apex on the others ; the 

 tips are also narrowly pale). In the middle of the prothorax there is a slightly 

 elevated subtubercular space that appears to be the remnant of a median carina. 

 Of the four specimens before me two were identified with doubt, by Blackburn, 

 as P. vitiensis, Fvl., but they do not agree with the description, as on one of 

 them the head and prothorax are uniformly dark castaneous, and on the other 

 uniformly pale castaneous (the specimens before Fauvel had the prothorax 

 trivirgate), and there are other differences from the description.

A specimen, from Mount Tambourine, agrees with the description of this 

 species, except that it is smaller (5.5 mm.) ; but as several species vary con- 

 siderably in length, apart from post-mortem contractions, the difference in size 

 is probably of no importance.

9 . Black ; antennae, palpi, and legs flavous, mandibles, labrum, and coxae 

 with a slight tinge of red. Clothed with straggling, ashen setae. 



Head small and (between labrum and base) transverse; with numerous 

 large punctures, sparser in middle than elsewhere. Eyes large, about one-fourth 

 longer than basal joint of antennae. Mandibles long and acute, with a rather 

 small acute tooth about middle. Antennae thin, first joint almost as long as 

 second and third combined, third slightly longer than second and slightly shorter 

 than fourth. Prothorax slightly longer than greatest width, which is near apex, 

 strongly rounded in front, behind the greatest width strongly obliquely nar- 

 rowed to base; with irregular rows of very large punctures. Elytra small, 

 sides strongly rounded ; with rather numerous, large, deep punctures. Abdomen 

 more than half the total length, most of the segments on the upper-surface 

 with large oblong punctures, close together at base, then with round ones not so 

 close together, and smaller ones about tips ; on under-surf ace the punctures are 

 somewhat similar but more numerous ; anal styles long and acute. Legs rather 

 long and thin, hind tibiae subtriangularly dilated and notched near outer apex. 

 Length, 10 mm.
