margins, the lower edge of the posterior band einarginate at the 

 apex. 



Length 2|-3| lines. 



Head greenish black at the vertex, with some punctures near 

 the eyes, the space surrounding the latter and the lower portion 

 of the face flavous ; labrum black ; antennae short, reaching only 

 to the base of the elytra, black, the apical joint obscure fulvous, the 

 basal joints stained with testaceous at the apex, the fourth joint 

 very slightly longer than the third ; thorax nearly three times as 

 broad as long, the sides straight at the base, rounded in front, the 

 anterior angles produced outward into a tooth, the surface with a 

 few minute punctures, the sides broadly flattened ; scutellum 

 black ; elytra convex, nearly parallel, the lateral margins narrowly 

 and a transverse straight narrow band at the middle as well as the 

 apex flavous, the rest of the surface occupied by two broad 

 transverse metallic blue bands, the lower edge of the posterior 

 band emarginate near the apical angle, the punctuation very fine, 

 more strongly marked in the flavous portion ; underside and legs 

 black.

Closely allied in coloration to several other species, notably to 

 CE. honesta, Illig., CE. eburata, Germ., (E. bifasciata, Baly, and 

 (E. steinheili, Jac, but differing from (E. honesta in the shape of the 

 posterior blue elytral band, which does not extend to the lateral 

 margins as is the case in the last-named species, and in the black 

 colour of the legs : CE. eburata is described as having a black hind 

 margin to the thorax and black elytral bands ; CE. bifasciata has a 

 fulvous underside and legs as well as similarly coloured head ; 

 CE. steinheili is much larger and differs likewise in the colour of the 

 head, antennae, and underside ; while CE. blanda, Har., has only the 

 base and the apex of the elytra blue. In the present species the 

 blue elytral bauds are divided by a perfectly straight fulvous band 

 at the middle, which is half the length of the dark band at the base; 

 the emargination of the posterior band near the apex will further 

 help to distinguish CE. quadrvplagiata, in one specimen the flavous 

 central band does not quite reach the suture.

Flavous, the base of the head and the antennae (the basal joints 

 excepted) black; thorax flavous, impunctate ; elytra finely punc- 

 tured, a transverse band at the base, another below the middle, 

 and the extreme apex metallic blue. 



Length 2 lines. 



Head with a few deep punctures on the vertex, bluish black, 

 the lower part of the face flavous ; antennae black, the lower three 

 joints obscure fulvous, third and fourth joints equal ; thorax twice 

 and a half broader than long, the sides moderately rounded, very 

 obsoletely angulate at the middle, the anterior angles dentiform, 

 the surface impunctate, flavous, very obsoletely sulcate near the 

 base; scutellum black; elytra closely and finely punctured, flavous,
