In pattern of the elytra closely- allied to Gr. concinna (Chevr.), differing, however, 

 from this species in tlie colonr of tin' antennae and in the style of marking of the 

 prothorax. From Gr. frtrittata sp. nov., again, it may be distingnished by the 

 colonr of the antennae, by the form of tlie ])rothoracic brown bands, and by the 

 pattern of the elytra.

Long. 11 mm., elytr. 7^, lat. 4. 



Head pale ochreons, clothed with rather sparse wliite hairs on tlie front and 

 cheeks ; a small spot behind each eye of a black colour. Antennae black, a 

 third longer than the body ; scape tawny on the underside, and punctnlated above, 

 with the apex somewhat rugose and granular. Anterior constriction of the jiro- 

 thorax very feeble, and the anterior transverse groove entirely disapjiearing on 

 the n])perside ; sides with a white patch at the base, which is continued to the 

 base of the elytra at the inside of the shoulder. Scntellnm ochreons and semi- 

 circular. Elytra with an oblique ochraceous baud running from the scutellum to 

 the outer margin, bordering the basal white marking, and laterally shading off into 

 white, chiefly towards the base, underneath the shoulders ; the remainder of the 

 elytra black, except a small spot standing almost in the middle upon the suture 

 and a postmedian transverse band, which are both of an ochreous colour ; this baud 

 a very little curved on each elytron, and not quite reaching the external margins. 

 Apex of the elytra with a grey pubescence. Meso- and metasternum white, with 

 a faint tint of olive biiff. Abdomen black ; the apex slightly pitchy, and clothed 

 with a somewhat greyish pubescence. Anterior and intermediate legs tawny 

 ochreous ; posterior legs black, their tarsi brownish, with a buff-coloured third 

 joint.
