 parallel sides and excavate from the middle, punctate-striate, 

 the punctures being large, round, and shallow ; the inter- 

 stices before the declivity are smooth, with small uniseriate 

 piliferous punctures down the centre; at the commencement 

 of the declivity each interstice has a sharp tooth, with one or 

 two longish hairs close to it ; interstices 3 and 4 also have a
