106 Mr. W. S. Dallas's Sketch 



Scutellum deep purple, with the base (irregularly), a transverse 

 band across the disc, before the middle, a narrow central line 

 uniting these, and a small spot on each side of the latter, shining 

 violet. The margins of the elytra brownish purple. Abdomen 

 with a strong furrow at the base, bright red, with a violet reflec- 

 tion, smooth, shining, very finely and moderately punctured ; a 

 black spot round each of the stigmata, and a faint band of the 

 same colour across the terminal segment. Anal plate red. Breast 

 purple, variegated with violet and greenish tints, shining, thickly 

 and finely punctured, the antero-lateral margins and lateral angles 

 red. Thighs brassy purple; tibiae shining violet; tarsi black. 

 Head beneath violet and green, shining, strongly punctured ; 

 orange at the base. Antennae (mutilated) shining violet. Ros- 

 trum brassy black, basal joint pale pinkish violet. 



The spots in this beautiful species appear to be arranged as in 

 P. Drurcei, except that the two subapical ones are wanting. The 

 others can easily be traced in the violet tints of the base, and the 

 broad band across the middle of the scutellum.

 The spots on the scutellum are placed, — three basal, of which 

 the central one is large, triangular, and produced on each side at 

 the base, in such a manner that it appears as though in the nor- 

 mal state there would be an additional spot on each side, as in 

 P. Drurcei ; two behind these, a row of four across the disc, 

 rather behind the middle, and two subapical. It is rather singu- 

 lar, that all the three specimens with which I am acquainted have 

 (as noticed by Mr. White, 1. c. sup.) a strong impression across 

 the disc of the scutellum, in front of the transverse row of spots, 

 in two instances, certainly, increased since the death of the insect, 

 but in the third apparently in the same condition as during its life. 

 This character, if it be one, exists in no other species. 



I have never seen any specimens with the spots confluent, but 

 if such should occur, they would be easily distinguishable from P.
