24 E. punctatissimus. Laete viridi-seneus, supra et subtus confertissime subtiliter 

 punctatus ; thorace subtransverso, capite non angustiore, antice profunde impresso, 

 dein canaliculate, disco utrinque foveato ; elytris latitudine sesqui longioribus pone 

 basin leviter sinuatis, foveis ocellatis purpureis 4-plici serie impressis, spatiisque laevi- 

 gatis 2-plici serie notatis : pectore medio larri, tibiis femorumque basi testaceis. Long. 

 27, lat. -13. 



Sault ; common. Punctuation much finer and more dense than in E. ruscarius (Say). 

 The anterior levigated space is quadrate and extends to the suture : the sides of the 

 abdomen are so finely punctured as to appear granulate. 



25 E. sinuatus. Laete viridi-tcneus, supra et subtus confertissime subtiliter punctatus, 

 thorace latitudine fere longiore, capite parum angustiore, antice profunde transversim 

 impresso, canaliculate, disco utrinque foveato ; elytris latitudine duplo longioribus, 

 pone basin profundius sinuatis, dein vix conspicue ampliatis ; foveis spatiisque laa- 

 vigatis sicut in praecedente : pectore medio leevi, tibiis femorumque basi ferrugineis. 

 Long. -31, lat. -13. Pic; two specimens. Narrower than the preceding, the punctures 

 of the side of the abdomen are more distinct ; but still the pectora are more closely 

 punctured than in E. ruscarius. 



26 N. punctatus. Nigro-aeneus, nitidus capite 7-striato striis externis latis, thorace 

 transverse, postice angustato, angulis posticis rectis, punctato, disco utrinque laevi, 

 basi utrinque foveato : elytris ante medium 1-foveatis, stria scutellari unica notatia, 

 suturali, externisque 8 minus approximatis dense punctatis, stria 7 mox pone hu- 

 merum, alteris versus apicem levioribus, 6 ta solum Integra ; tibiis antennarumque art. 

 2ndo 310 410 que rufescentibus. Long. '2. 



Size of N. porrectus ; but the striae are more densely punctured, less obliterated, and 

 the feet and antennae black. It resembles much N. confusus Lee. (semistriatus Say, 

 teste Harris), but the 1 st stria is not curved and exarate at tip, the base of the anten- 

 nae less decidedly pale, and the scutellar stria is not double.
