CHLORIDOLUM. 199 



glabrous and subnitid. Head punctulate densely above and very 

 sparsely or not at all in front. Antennae about twice as long as 

 the body in the tf , one-fourth longer than the body in the $ ; 

 first joint strongly but rather sparsely punctured, subsulcate along 

 its front face, and produced in a sharp angle or tooth at the apex, 

 Prothorax with a strong sharp tubercle at the middle of each side, 

 and an obtuse transverselv elongated tubercle near the front 

 margin ; the upperside transversely striated except over the 

 middle of the disc; the disc slightly raised, and tuberculate on 

 each side, just in front of the basal constriction. Scutellum 

 smooth near the base and impressed with a median groove ; more 

 or less rugulose posteriorly. Body beneath green; the hind 

 breast sparsely pubescent ; the abdomen glabrous, very glossy 

 and with a slightly brassy tint. Hind femora of the tf extending

Metallic green, with the legs and antennae very dark blue, the 

 latter covered except near the base with a faint black pubescence ; 

 prothorax with two patches on the disc, and the elytra each with 

 a broad sub-sutural band, covered with short black tomentum. 

 Head punctured closely ou top, rather sparsely in front, impressed 

 with a median line that extends from the clypeus to the vertex. 

 Antennae of cT longer than twice the body ; first joint closely 

 punctate ; third barely longer than the fourth and not quite as 

 long as the fifth. Prothorax transversely plicate and glossy, 

 except on the disc between the anterior and posterior transverse 

 groove ; this central area has a dull granulated appearance, but 

 bears sometimes a smooth glossy line or band along the middle. 

 Scutellum smooth and shining. Elytra with a short sutural band 

 behind the scutellum, and a band, somewhat brassy in colour, that 

 begins at the shoulder and runs backwards along the middle of 

 each elytron, distinctly and rather closely punctate, and glossy; the 

 rest of the surface very finely granulated and dull. Body beneath, 

 except the prothorax, faintly covered with a greyish pubescence 

 which gives silvery reflections in certain lights. Femora closely 

 punctulate, the hind pair very closely and more finely than the 

 others ; tarsi brownish black.
