POPILLIA. 65 



c? . The legs are stout and the tarsi very short and thick. The 

 front tibia is very broad, with very short but sharp testh, and the 

 middle tibia is short and rather inflated The inner Front claw is 

 broad, blunt and minutely cleft at the extremity, the outer middle 

 claw is long but not cleft. 



5 . The front and middle legs are slender, and the hind ones 

 stout, with short thick tarsi. 



Length, 11-13 mm. ; breadth, 6-7 mm.

Several of the supposed varieties of PopilUa marginicollis belong 

 to different species, but a melanic form (var. atrata, Kr.) occurs 

 in which the prothorax is of a deep purple colour and the elytra 

 entirely black or with a narrow pale basal margin. The name 

 P. purpuricollis has also been applied by Kraatz to specimens with 

 a purple thorax, but these cannot be recognised as representing 

 a definite variety.

Reddish testaceous, with the head (except the clypeus), the 

 middle of the pronotum, the scutellum and parts of the lower 

 surlace dark green, entirely suffused with a metallic green lustre 

 except upon the elytra, which have usually more or less distinct 

 longitudinal dark lines. 



It is elongate in shape and not very convex. The clypeus is 

 very minutely rugulose, and the rest of the head distinctly punc- 

 tured. The pronotum is very finely and sparingly punctured, with 

 the middle of the basal part quite smooth. The scutellum bears a 

 few very minute punctures and its apex is rounded. The elytra 

 have each five very deep equidistant dorsal striae bearing confluent 

 punctures at the bottom, and the intervals are smooth and very 

 convex. The pygidium is coarsely transversely striolated and 

 bears two large white hairy patches at the base and a line of 

 irregular hairs on each side almost meeting at the apex. The 

 ventral segments are divided by transverse carinae at the sides and 

 doubly fringed. The mesosternum is moderately produced. 



Length, 9-12*5 mm.; breadth, 5-7 mm.

The specimen in the Genoa Museum to which the varietal name 

 brunnicollis was given by Kraatz is an immature individual. I 

 have stated in Ann. Mag. Nat. Hist, (8) xii, 1913, p. 38, the 

 reasons why this varietal name cannot be employed for the 

 species.
