324 Mr. G. R. Waterhoiise's Descriptions 



c'lytiis squamis cseiuieo-viiidibiis indiitis, arcis 7-roLunclatis 

 denudatis. 

 Long. Corp. 6 liii., lat. 3 lin. 



In size and form this species closely resembles the P. monili- 

 ferus. Head and rostnnii with distinct scattered punctures, the 

 former with a longitudinal groove above, which runs into a large 

 triangular fovea on the basal half of the rostrum. The scales on 

 these parts are arranged so as to form a line on the head, in fact, 

 there filling up the longitudinal groove ; a patch on each side 

 under the eye, and another on each side of the apical half of the 

 rostrum. Thorax subglobose ; truncated before and behind, and 

 with very minute punctures, which are rather widely scattered. 

 The uncovered and the scaly parts of the thorax are about equal in 

 proportion : the markings formed by the scales may be described 

 as a broad, transverse, mesial band above, — a central broad mark 

 connecting this with the posterior margin, and a very bx'oad band 

 covering the sides ; or, a more accurate idea might perhaps be 

 conveyed by describing the thorax as covered with scales, with 

 the exception of an anterior central patch above, — more or less 

 divided behind by a slender line of scales ; sometimes nearly 

 divided into two circles, and sometimes into two squares; — and 

 two quadrate large denuded patches behind. Elytra convex, sub- 

 ovate (generally less inclining to a globose form than in P. monili- 

 ferus), punctured in stride, the punctures for the most part distinctly 

 separated ; the surface of the elytra is covered with scales, with the 

 exception of two transverse bands, each composed of three round 

 (or nearly round) large denuded areas; the first of these bands is 

 situated near the base of the elytra, and the second rather behind 

 the middle ; the three circular areas in each are separated by 

 narrow lines of scales, but between the outermost area of each, 

 and the outer margin of the elytra, there is a considerable space : 

 besides these areas there is a seventh at the apex of the elytra, 

 which is rather small, and generally throws out a short branch on 

 each side, which runs for a short distance along the outer margin 

 of the elytron. All the scales are of a greenish blue colour, but 

 those which are nearest to the denuded spaces are much paler 

 than the rest, and form conspicuous pale lines encircling the scale- 

 less parts. The femora have each two interrupted rings of scales. 



Of this species Mr. Cuming brought home an immense number 

 of specimens. There were also in that gentleman's collection 

 many specimens of each of several varieties (or rather what I 

 believe to be varieties) which I will proceed to notice.
