Chontales, Mr. Belt; also Brazil? (coll. H. W. Bates). 



Resembles Trestonia capreola; but elytra shorter and 

 broader, antennae iinicolorous brown, &:c. The dark, 

 velvety crescent-shaped spot of the elytra is in the same 

 position, far from the apex, and forms a smooth curve on 

 its anterior margin, with two indentations in its posterior 

 margin. The apical part is rather more tawny or ruddy 

 in colour than the rest of the body and the cinereous spot 

 is very oblique. The shoulders are subfalcate as in Tr. 

 capreola. It agrees with none of the numerous species 

 described by M. Buquet. 



HopUstocerus gemmatus, n. sp. Ovatus, \drldi-ffineus, 

 cinereo-tomentosus, elytris (postice rotundato-dilatatis) 

 passim maculis elevatis nitidis viridi-ieneis conspersis, 

 spatiis depressis dense tomentosis ; antennis nigris, scapo 

 nitido, elongato-pyriformi, articulis 3 — 4 basi griseis, 2 — 

 4 intus apice valde spinosis. Long. 4^ lin. $ . 



One example. 



Differs in shape from other species of the genus, ap- 

 proaching Cyclopeplus ; but only moderately convex. 

 Antennas as in the typical species, second, third and fourth 

 joints strongly spined, and eleventh slender, claw-shaped ; 

 the scape, however, is more slender at the base than in 

 H. gloriosus. Beneath, the body and coxre are dark, 

 glossy, brassy-green, with the sides coarsely clothed with 

 laid ash-coloured hairs ; the legs are black and similarly 

 pubescent. The upper surflice is coarsely tomentose ; 

 the head scantily so, with green ground colour ; the thorax 

 very short and transverse, unarmed, and with five naked, 

 glossy, slightly raised spots on the disk. The elytra are 

 gradually dilated from the base ; their surface more densely 

 tomentose, but only in the depressions; the raised parts 

 consisting of a multitude of raised tubercles very irregular 

 in size and sha]3e and marked Avith large punctures; all 

 glossv, dark metallic-green.
