ver larger and differ in the colour of the femora; in others the 

 elytra are entirely blue with the exception of the fulvous lateral 

 margin which is narrowed anteriorly by the blue portion , cor- 

 responding in that respect with the typical forms, in which the 

 blue spot is placed close to the lateral margin at the same place; 

 as I cannot find any other structural differences, I have no doubt 

 that the specimens are varieties of M.^ Baly's species. 



6. I*liylloclaixfis impz-essieollis, n. sp. 



Fulvous; head, antennae and part of the underside violaceous 

 blue; thorax swollen, the disk divided by deep depressions; elytra 

 strongly punctate-striate , fulvous, a spot at the base , a smaller 

 one at the sides and a transverse one near the apex violaceous. 



Length 2 lines. 



Head impunctate, with a deep central fovea and a. longitudinal 

 depression above the inner margin of the eyes ; antennae exten- 

 ding beyond the base of the thorax, black, the first G or 7 

 joints metallic blue; thorax with the anterior portion strongly 

 swollen but divided at the middle by a deep longitudinal de- 

 pression and another more oblique one at each side, near the 

 posterior angles, all these depressions are deeply punctured; 

 scutellum violaceous ; elytra fulvous, strongly and regularly punc- 

 tate-striate , the punctuation rather more feebly impressed near 

 the apex; a large subtriangular violaceous spot surrounds the 

 scutellum, another smaller and squareshaped spot is placed an- 

 teriorly close to the lateral margin and a more transversely 

 shaped one, below the middle; underside fulvous, part of the 

 breast, margins of the abdominal segments and the legs metallic 

 violaceous blue. 



Hah. Australia, Cape York, Somerset (L. M. D'Albertis). 



This species, although closely allied in its pattern and colou- 

 ration to P. Jansoni is quite distinct from the latter on account 

 of the strongly swollen disk of the thorax and the umch deeper 

 and more regularly punctate elytra.
