126. ArGDTOR NITIDIPENNI3. n. Sp. 



Length 3 lines. 

 Black, nitid. Head with the frontal impressions long. Thorax 

 of the same form as in A. foveipennis, but with the basal impres- 

 sions broader, shallowei', and somewhat rugose and punctured. 

 Elytra brilliant and striated with the abbreviated basal stria long 

 and joining the first stria, and with three punctures on the third
