Buprestifhe from Madagascar. 181 



and there is a little coppery tint at the apex ; on the 

 back there are a few dark purple spots, and a little way 

 from the ajiex there is one on the margin ; the apex is 

 slightly truncate, and the outer tooth is seen with much 

 difficulty. The sculpture is as follows : there is a 

 prominent costa next the suture, which becomes oblite- 

 rated some distance from the apex ; next to this is a less 

 elevated costa, which extends to the apex, but is frequently 

 interrupted by round rugulose impressions ; then there 

 is a prominent costa which is obscure at the base, but 

 which extends nearly to the apex ; beyond these there 

 are portions of two or three costae, which are much 

 interrupted by impressions ; the surface beyond this is 

 more flattened and is strongly punctured ; close to the 

 apex on the margin there is a small frosted golden 

 impression filled with short pale pubescence, and there is 

 a rather larger one a little above it still on the margin. 

 The under side of the insect is seneous, tinted with 

 coppery, with brassy punctuation ; the prosternal process 

 is not thickly punctured, it is grooved on each side; the 

 abdomen is strongly marked with elongate punctures; 

 the apical segment is blue, punctured with golden green, 

 and with a narrow frosted margin of green. The re- 

 flexed portion of the elytra is shining blue, slightly 

 concave, punctured posteriorly. Legs green. 



Length 11 lines. 



Hah. — Madagascar. 



This species is difficult to locate, but I think it is best 

 placed near P. zivetta.

1. The typical form of this species, according to a 

 specimen compared with the type by Mr. Edward 

 Saunders. Bather olive-aeneous, with three brassy hues 

 on the thorax, with a considerable amount of brassy 

 frosted space on the elytra, especially below the shoulders 

 and on the margin, and always with the sutural mterstice 

 brassy. One specimen in the Museum cohection has 

 almost the whole of the elytra taken up with the brassy 

 colour. 



This form occurs at Antananarivo. 



2. Specimens from Fianarantsoa. More brown-a;noous 

 in general colour, and are rather smoother. 



3. Specimens from Fianarantsoa. Uniform coppery
