punctured : the parts above the antennae and behind the eyes 

 are thinly covered with long white hair. Mandibles black, 

 the base thickly covered with white pubescence. Palpi black. 

 Thorax blue, with purple and brassy tints; above it is closely, 

 but not very strongly, punctured ; the sides of the scutellum are 

 closely, irregularly, longitudinally striated ; the postscutellum 

 towards the apex is irregularly transversely striated. Median 

 segment coarsely, irregularly, transversely striated ; there is 

 a broad shallow furrow clown the middle. The hollowed part 

 of the propleura? bears a few striae ; the mesopleurae coarsely 

 rugose, the punctures running into oblique striae towards the 

 apex ; the metapleurae above closely, strongly, obliquely 

 striated, the base below is minutely punctured, the apex 

 coarsely closely reticulated. The four anterior legs are blue ; 

 the tibiae and tarsi darker coloured ; the hinder femora red, 

 narrowly purple at the base and apex. Wings uniformly 

 fuscous hyaline, highly iridescent and with a violaceous tint ; 

 the stigma and nervures are fuscous. Abdomen bright 

 metallic blue, very smooth, and shining. 



Allied to P. blanda and P. prophetica, from both of which 

 it may be known by the strongly and closely punctured head 

 and thorax, by the punctured and longitudinally striated 

 scutellum, and by the wings being not clear hyaline. The 

 head and thorax may have dark purple and brassy tints. 

 With the male the anterior femora and tibiae may be testa- 

 ceous in front.

 the pronotum, the sides of the scutellum, the postscutellum, 

 the base of the petiole, the apical two thirds of the third 

 segment, and the apices of the following three segments 

 narrowly, rufous ; the legs black, the apices of the four froot 

 femora and the four anterior tibiae in front yellow ; the wings 

 smoky, darker in front, the nervures and stigma black. 6 .

Scape of antennae for the greater part yellow ; the base of 

 the flagellum broadly, the apex narrowly beneath, brownish. 

 Head closely and distinctly punctured ; the face and clypeus 

 thickly covered with silvery pubescence. Clypeus broadly 

 roundly projecting, the lower inner orbits, a large mark, 

 trausverse at the base, becoming obliquely narrowed below 

 and ending in the middle in a rounded point, and the antennal 

 keel are yellow. Thorax black ; a broad band on the pro-
