(Pase 147) 



This species is very closely allied to castanoptera , but also bears 

 some likeness with aguatilis . From castanoptera it is especially sepa- 

 rated by the bronze reflection of head and pronotum, the shorter distal 

 joint of the antennae, and the more robust punctation of elytra; from 

 aquatilis namely by longer elytra, narrower pronotum, and the less broad, 

 anteriorly more narrowinj form of the body. 



Black, finely haired; forebody with modified gloss, head and prono- 

 tum with ore- or bronze shine; elytra darkly yellowish-brown, most often 

 with feeble bronze-like reflection; abdomen glistening black; antennae 

 black or pitch-black, their first joint reddish-yellow, the following two 

 orownish; legs reddish yellow. 



Head, pronotum and elytra more distinctly shagrened in surface than 

 in castanoptera , and less glistening; the head narrower . than pronotum, 

 very finely and indistinctly punctated; the antennae rather slender, feeb- 

 ly thickened distally, their third joint most often a little longer than 

 the second, the fourth narrower and shorter than the fifth, both longer 

 than broad, the following outer joints (6-10) as long as broad or the next- 

 last ones feebly transverse, the distal joint not longer than the two pre- 

 ceding joints together. Pronotum distinctly narrower than elytra, hardly 

 li times as broad as long, slightly narrowing posteriorly with nnterlorly 

 rounded, posteriorly more straight sides, very finely, tut not very dense- 

 ly granulate-punctated, with a transverse fovea and a most often distinct 

 impression posteriorly before scutv^llum; elytra \f/^ times as long as pro- 

 notum, with rather robust ana dense, scabrous or granulate punctation, dis-
