58. A.lbiru.s antennatns , n. sp. 



Below metallic greenish or bluish, above obscure aeneous, 

 antennae with the apical joints dilated, the head and thorax 

 cupreous, very closely punctured, elytra strongly and closely 

 punctured with longitudinal narrow smooth lines, the sides 

 slightly transversely rugose. 



Var. Above entirely dark aeneous. 



Length 3-5 lines. 



Head strongly and rather closely punctured, the vertex more 

 sparingly punctate, the middle of the front with a more or less 

 distinct small tubercle, the anterior margin of the clypeus emar- 

 ginate, black as well as the labrum and the mandibles, antennae 

 black, the second and third joints more or less fulvous, the 

 last five joints broadly dilated ; thorax twice as broad as long 

 the sides strongly rounded at the margin , the anterior angles 

 pointed, the surface strongly, closely and rather evenly punc- 

 tured, the punctures more crowded at the sides but all of equal 

 size, a very obsolete oblique depression is placed at each side ; 

 scutellum broader than long , smooth ; elytra convex, subcylin- 

 drical , very closely and much more strongly punctured than 

 the thorax, the punctures arranged in very closely approached 

 semiregular rows , interrupted in the female by longitudinal 

 narrow smooth spaces , the interstices at the sides moderately 

 transversely rugose ; underside and legs bluish or greenish, not 

 very shining and clothed with short whitish pubescence.

A . antennatus seems to differ from any of its congeners in the 

 greatly dilated apical joints of the antennae, in the punctuation 

 of the thorax which does not consist of smaller and larger punc- 

 tures but is regular and close, and in the less rugose elytral 

 interstices at the sides; the colour of the labrum is also con- 

 stantly black as well as the lower edge of the clypeus.
