1905.] OF PHYTOPHAGOUS COLEOPTERA. 447 



a broad transverse band at the base and another below the middle, 

 connected at the suture, metallic green. 



Length 9 millim. 



Head fulvovis, with a few punctures near the eyes, the chqjeus 

 with a strongly raised, central carina, eyes large ; antennae long 

 and slender, third joint shorter than the fourth ; thorax more 

 than twice as broad as long, the sides strongly rounded, bi'oadly 

 flattened ; the disc very convex, very minutely punctured when 

 seen under a strong lens, fulvous ; scutellum broad, fulvous ; 

 elytra convex, scarcely widened at the middle, with a shallow 

 transverse depression below the base, extremely finely pvuictured, 

 the punctures of different sizes, with two very broad, transverse, 

 metallic green bands, the first at the base not extending to the 

 margins but nearly to the middle, the second band immediately 

 below the latter, of nearly the same width and not extending to 

 the apex ; these bands are therefore separated by a narrow trans- 

 verse and straight band of the ground-colour which does not quite 

 extend to the suture and rounded at its inner termination ; 

 under side and legs fulvous. 



Hah. Amazons. 



Of more parallel shape than 0. cenea, and distinguished from 

 that and other similarly marked species by the bright metallic-green 

 bands of the elytra, separated at the middle by a straight narrow 

 fulvovis band which does not extend quite to the suture ; in 

 0. bipartita, which has similarly coloured metallic baiids, these are 

 divided before and beloiv the middle. 



Oedionychis cardikalis, sp. n. (Clark, MS.). 



Piceous, head and thorax flavous, the latter narrowed in front ; 

 elytra microscopically punctured, flavous, a broad transvei-se band 

 at the base and another of more rounded shape below the middle, 

 violaceous blue. 



Length 10 millim. 



The principal differences which separate this species from 

 many similarly coloured forms are to be found in the large 

 general size, anterioiiy narrowed thorax, and the shape of the 

 eljrfcral bands ; the eyes are well separated, and the head is 

 sparingly and finely punctured ; the frontal elevations and the 

 carina are proportionately broad ; the antenna? have very slender 

 and elongate joints, the lower three are fulvous, the rest black 

 (in the British Museum specimen, named by Clark, the antennse 

 are entirely fulvous). The thorax is less transverse than in many 

 other species, distinctly narrowed anteriorly, with strongly rounded 

 sides, the anterior angles are blunt above, but have a short pro- 

 jection below the margin in front of the eyes ; the lateral sulci 

 are rather broad and shallow ; the scutellum is flavous ; the 

 punctuation of the elytra can only be seen with a very strong lens ; 

 of the blue elytral bands, the first extends nearly to the middle 

 and has its posterior margin straight or neai'ly so, in the second 

 band the anterior and posterior margins are rounded, so that the
