of original specimens, or in furnishing me with information

Genus Apocyrtus, Erichson. 



Apocyrtus Schcenherri. 



Ap. niger ; capite nota inter oculos et utrinque infra oculos ; thorace not^ 

 transversa antica, maculisque duabus lateralibus et superioribus, necnon 

 elytris macuHs viginti-duabus, splendide cupreis, vel aureo-cupreis ; rostro 

 rugoso-punctato ad basin transversim impresso, capite et rostro canaliculo 

 longitudinali impressis ; thorace crebre punctato ; elytris globoso-ovatis

This is the largest species of the genus I am acquainted with ; its 

 elytra are less globose, and the thorax is larger in proportion to the 

 elytra than in Ap. infiatus : the beautiful metallic spots with which it 

 is adorned vary somewhat in hue, being in some specimens of a red- 

 dish golden tint, and in others of a copper colour. The rostrum is 

 thickly punctured, and the punctures are more or less confluent ; a 

 transverse indented line separates the rostrum from the head, and a 

 longitudinal impression runs from this line towards the fore-part of 

 the rostrum, becoming gradually broader in front and terminating in 

 a line with the insertion of the antennae. The headsis rather spa- 

 ringly punctured ; between the eyes is a small metalhc spot (in some 

 specimens wanting), and beneath the eye is an oblique mark formed 

 of brilhant scales. The thorax is very nearly equal in length and 

 breadth, subglobose, and truncated before and behind ; on the ante- 

 rior margin is a transverse mark, about midway between the ante- 

 terior and posterior margins ; and towards the side of the thorax is 

 a round spot, and just above the insertion of the femur is a broad 

 oblong mark formed of brilliant scales ; the surface of the thorax is 

 rather coarsely punctured, and the punctures are many of them con- 

 fluent. The elytra are more than one-third broader than the thorax 

 — sometimes nearly twice as broad — about one-third broader than 

 long, ovate and very convex ; they are punctured, and the punctures
