and are set with fine close punctures much like the seriate punc- 

 tures of Chalcopterus ciipripennis but a little more crowded and 

 more deeply impressed ; the interstices of the striie are distinctly 

 convex esijecially near the apex. The anterior coxae are more 

 widely separated and the eyes much more contiguous than in most 

 Amarygmi. In general appearance this insect is much more like 

 a Chalco'pterus than an Amarygmus.

'Ihis species is allied to A. torridus, Pasc, A. tardus, Blackb., 



ifec, in respect of its sculpture but is a much narrower insect than 



either of those two; it ditTers from A. tardus also in the seriate 



foveas of the elytra not being coloured differently from the general 



surface. The fovese of the series are somewhat uniform in size, 



but those in the middle part of the series near the lateral margins 



are a little larger than the rest. In a series (say the 4th from
