190 GEO. n. HORN, M. D, 



are the sparsely punctured thorax, coarsely punctured elytra and the 

 deep bronze tinge of the surface. 



Occurs in the southern Atlantic States from Maryland to Georgia, 

 also in Ohio. 



D. iul^uln, Lee. — Rufo-testaceous, elytra brilliant green shining with 

 narrow pale limb. Head very coarsely and densely jmnctured. sparsely pubes- 

 cent, frontal suture impressed, clypeal margin narrowly reflcxod. Thorax 

 rather sparsely but coarsely punctured, sparsely pubescent. Elytra brilliant 

 metallic green, coarsely and deeply punctured, smoother at basal third, surface 

 sparsely pubescent. Body beneath rufo-testaceous, sparsely punctured and 

 pubescent. Legs paler. 



I have seen only females of this species. It can only be confounded 

 in description with ftmadn from which it differs by its larger size, 

 more coarsely punctured thorax and the color of the elytra. Varieties 

 rarely occur with the elytra testaceous. 



Occurs in Oregon and Vancouver. 



D. truncata, Lee. — Rufo-piceous. Head coarsely punctured, sparsely 

 pubescent, frontal suture deeply impressed. Clypeus truncate in front, sides 

 slightly convergent, angles acute, margin rather broadly reflexed and testa- 

 ceous. Thorax finely rugulose, sparsely pubescent. Elytra with paler limb, 

 surface bronzed, punctured and coarsely wrinkled. Body beneath sparsely 

 punctured and pubescent. Legs testaceous or piceo-testaceous. 



This species which is about the smallest, is easily known by the 

 truncate clypeus and the thoracic sculpture. 

 Occurs in Colorado, Oregon and California. 



I>. elypoata, n. sp. — Form robust, color piceous, elytra luteous without 

 metallic lustre. Head coarsely and densely punctured, frontal suture not im- 

 pressed. Clypeus prolonged over the labrum, rounded in front, slightly dilated 

 at the sides, margin moderately reflexed. Thorax coarsely and densely punc- 

 tured especially toward the sides, sub-apical line obliterated at middle, basal 

 marginal line feeble, disc moderately convex, sides very obtusely sub-angulate, 

 posteriorly oblique, hind angles obtuse, margin in front crennlate. Elytra 

 luteous without surface lustre, obsoletely tricostate, surface coarsely punctured. 

 Body beneath sparsely punctured, abdomen and sternal side pieces finely 

 alutaceous, surface sparsely pubescent. Legs piceo-testaceous. Length .42 

 inch; 10.5 mm. 



This .species has somewhat the aspect of the succeeding group, but 

 has no median thoracic line. The prolonged clypeus will serve to dis- 

 tinguish it at once from all others in our fauna. 



One specimen 9 , California. Henry Edwards. 



I>. albieollis, Burm. — Testaceous or piceo-testaceous, elytra with moder- 

 ate aeneous tinge. Head coarsely and densely punctured, moderately pubes- 

 cent, frontal suture feebly impressed, clypeus testaceous, margin moderately 

 reflexed. Thorax coarsely but sparsely punctured, a deep median groove, 

 surface sparsely hairy, sides obtusely augulate at middle, posteriorly oblique
