CHALiENOSOMA.

small, third but slightly longer; the following segments are 

 nearly equal. Prothorax transverse and short, anterior margin 

 straight, sides somewhat rounded ; surface rather convex, with a 

 mixture of very minute and coarser punctures, while under a high 

 power the surface, besides bearing these punctures, is finely 

 granulate. Scutellum triangulnr, with surface granulate. Elytra 

 broader at the base than the prorhorax, with a depression behind 

 the base, very finely punctate except within the depression, where 

 the punctures are stronger, while besides bearing punctures the 

 surface is extremely finely granulate. Underside: first segment 

 of hind tarsi rather longer than the following segments together. 



Length, 5 mm.

132. Chalaenosoma metallicum *, Jacoby. 



Chalcenosoma metallicum, Jac, Trans. Ent. Soc. Lond. 1898, p. 157. 



Body rather widened behind. Colour metallic green ; antennas, 

 tibiae and tarsi more or less black ; labrum and mandibles black ; 

 basal segments of antennas more or less obscure fulvous; elytra 

 with a transverse band across the basal convex area, another at the 

 middle, and a third narrower band near the apex, purplish ; these 

 bands are variable, sometimes reduced to spots ; the basal purplish 

 band is narrow, not extending to either the suture or the lateral 

 margin, the median band is just behind the post-basal depression, 

 extending to the lateral margin but not to the suture, the pre- 

 apical band is much abbreviated, extending neither to the suture 

 nor to the lateral margin ; scutellum purplish. 



Head convex, impunctate, frontal tubercles narrowly transverse, 

 bounded by a deep channel behind, clypeus triangular, thickened. 

 Antennas extending to the middle of the elytra, the relative lengths 

 of the segments as stated under the genus. Prothorax transverse, 

 about one and a half millimetres broad and one millimetre long, 

 convex, sides somewhat rounded, surface scarcely perceptibly 

 punctate. Scutellum triangular. Elytra broader at base than 

 prothorax and with a deep depression behind the base, strongly 

 punctate within the depression ; the rest of the surface less 

 strongly but closely punctate ; humerus convex ; elytral margins 

 narrowly explanate. 



Length, 3|-5 mm.

* Jacoby wrote the specific name of this, the type-species of the genus, with 

 a neuter termination, thus making it agree with the second component of the 

 generic name. But in describing the five other species ten years later, he 

 gave the specific names of all of them feminine endings.
