1. D. dubia. Brassy-brown above; elytra with many small, quadrate, ele- 

 vated black spots ; beneath dull cupreous. — 9 1. long, 3£ I. wide. Pennsyl-

Brassy-brown above : head coarsely shagreened ; mouth green ; eyes pale 

 brown : thorax somewhat dilated at the sides, with a punctiform impression be-

 irregular, elevated, polished, black spots, of which some are quadrate, interstices

 truncate, with a minute tooth at the inner angle : beneath roughly punctured : 

 pectus canaliculate: abdomen ( $) emarginate at tip: feet roughly punctured,
