prominent anterior angles of the thorax, the more sparingly punc- 

 tured surface of the latter, and other particulars pointed out above. 

 From >S'. petelii the present insect differs further in the possession of 

 another tooth at the inner margin of the posterior tibiae and in 

 the less transversely wrinkled surface of the elytra. The size of the 

 species is often reduced to half the general length. A great many 

 specimens were obtained of either colour, but differing in no other 

 way. 



Crioceris chinensts, n. sp. 



Black ; thorax obscure fulvous, strongly and irregularly punc- 

 tured ; elytra very deeply and closely punctate-striate, the interstices 

 costate and wrinkled near the apex ; femora stained with rufous. 



Length 3|-4 lines. 



Head black, the neck fulvous ; the space surrounding the eyes 

 covered with yellow pubescence ; eyes very deeply notched ; clypeus 

 punctured and pubescent. Antennae extending slightly beyond the 

 thorax, black, the third and fourth joints equal, short, slightly 

 longer than the second joint, the terminal joints thickened, but not 

 broader than long. Thorax subquadrate, widened at the base and to 

 a less extent at the apex, the sides moderately constricted, the sur- 

 face irregulaily impressed with larger and smaller punctures, leaving 

 a narrow central space generally smooth and impuiictate, fulvous or 

 rufous; scutellum fulvous. Ehtra without basal depression, deeply 

 and closely punctured, especially at the sides, where tiie interstices 

 are costate and transversely raised. Underside and legs black, spar- 

 ingly covered with grey pubescence ; the femora more or less rufous 

 at the base. 



C. chinensis is closely allied to C. ruguta, Baly, from Japan, from 

 which it differs in the anteriorly more widened thorax and in the 

 much finer punctuation of the latter ; in C. rugata the anterior 

 portion of the thorax is rounded and not produced, and the disk is 

 very deeply, almost rugosely punctate ; the sculpture of the elytra, 

 however, is exactly the same in both insects, but the femora are 

 entirely black in C. rugata. 



Crioceris triplagiata, n. sp. 



Black ; head deeply constricted behind ; thorax longer than broad, 

 nearly impunctate ; elytra flavous or fulvous, remotely punctate- 

 striate, a large ovate spot extending to the middle on each elytron, 

 and the apex broadly, black. 



Length 4 lines. 



Head very deeply constricted behind the eyes ; the vertex raised 

 into two large tubercles ; eyes very prominent, deeply notched. 

 Antennae half the length of the body, the four lower joints shining, 

 the rest opaque, slightly thickened towards the apex, the joints longer 

 than broad. Thorax about one half longer than broad, the sides con- 

 cave at the middle, the surface without basal sulcation, black, very 

 shining, with a ievi very fine punctures near the anterior margin ; 

 scutellum black. Elytra with a very faint depression before the
