800 INSECTS OF LOUISIANA. 



New species of North American Insects, found by Joseph Barabi ::o, cbiefiy 

 in Louisiana. 



New Harmony, Indiana, January, 1832. 



COLEOPTERA. 

 BUPRESTIS Linn. 



B. THUREURA. — Scutel transversely elongated. 



Inhabits Louisiana. 



Body brassy greenish, with dilated, unequal, impressed punc- 

 tures : vertex with an acute, longitudinal, impressed line : antennae 

 green : thorax with the punctures more confluent each side, and 

 a longitudinal, glabrous line : scutel ti'ansversely elongated, sub- 

 bilobate : elytra with punctured striae ; interstitial lines irregu- 

 larly punctured and with unequal and irregular glabrous spaces : 

 edge not obviously serrate ; tip with a narrow subemarginate 

 truncation : beneath cupreous, anal segment emarginate. 



Length less than four-fifths of an inch. 



The breadth of the scutel is considerably more than double its 

 length. It resembles lurida F. (which is corrosa Dej.) but the 

 extraordinary latitude of the scutel distinguishes it ; that species 

 has also bidentate elytra, and a tridentate anal segment.
