1888.] PHYTOPHAGOUS COLEOPTERA. 341 



middle, the shoulders rounded, not grooved within ; the punctures 

 distinct, but only visible at tlie base near the suture and at the sides, 

 the middle of the disk as well as the apex nearly impunctate ; the 

 lateral margin thickened and accompanied by a row of deep punc- 

 tures. Underside and legs black, finely pubescent. 



This handsome species will be easily recognized by the pattern of 

 the elytra, the large ovate black spot occupying the middle of the 

 disk anteriorly, but not extending to either margin ; the apical third 

 portion is entirely black, this colour forming a broad transverse sub- 

 triangular band, the anterior margin of which does not quite extend 

 to the sides. 



Cryptocephalxjs chinensis, n. sp. 



Reddish fulvous ; the antennae, tibiae, and tursi black ; thorax 

 with three impressions ; elytra flavous, strongly punctate-striate, the 

 margins, a spot on the shoulder, and a narrow transverse band 

 below the middle, black. 



Length 2 lines. 



Head fulvous, with a few very fine, remotely placed punctures, 

 the clypeus and the space near the inner margin of the eyes flavous. 

 Antennae two thirds the length of the body, black, the three basal 

 joints more or less flavous below, the third joint one half shorter than 

 the fourth ; thorax nearly three times broader than long, narrowed 

 in front, the sides rounded and narrowly margined, the surface 

 entirely impunctate, with a distinct oblique depression at each side 

 and a very indistinct one at the base, reddish fulvous, very shining, 

 the posterior margin very narrowly flavous ; scutellum fulvous, 

 margined with brown, strongly raised. Elytra subcylindrical, parallel, 

 bright flavous, regularly punctate-striate on the disk, irregularly 

 punctured at the sides, narrowly margined with black, the shoulders 

 with a small black spot, and a similarly coloured narrow transverse 

 band placed below the middle and extending to either margin ; the 

 elytral epipleurae black, distinctly punctured. Below fulvous, finely 

 punctured, the outer margin of the tibiae and the tarsi black. 



Of this species, of which I cannot find any published description, 

 two specimens are before me, which only differ very slightly in the 

 elytral black band being more deeply black and extending across the 

 suture in one specimen, while in the other this band is slightly inter- 

 rupted near the suture. C. chinensis, on account of its coloration, 

 seems somewhat allied to C. crucijpennis, Suffr. 



COPTOCEPHALA BIFASCIATA, n. Sp. 



Black ; the basal joints of the antennse and the base of the tibiae 

 fulvous ; thorax transverse, fulvous, impunctate ; scutellum fulvous ; 

 elytra very finely semipuuctate-striate, fulvous ; a broad transverse 

 band at the base, and another, variable in size, slightly oblique, below 

 the middle, black. 



Length 2|-3 lines.
