32 DESCRIPTIONS OF NEW SPECIES. 



gris, pectore nigro ; pedibus flavis, antennis crassiusculis nigris, articu- 

 lus 4 primis ultimoque flavis. Long. '17. 



Middle States ; rare. Allied to B. cinctus, but the thorax is 

 narrower and more gradually narrowed in front, and the suture 

 is not yellow. The fifth dorsal segment of the abdomen (the first 

 of the black ones), as in that species, has the posterior margin 

 yellow. The abdomen is smooth above and sparsely but strongly 

 punctured beneath. 



106. B. rostratlis. Niger nitidus, capite latitudine plus triple lon- 

 giore, ore testaceo, thorace latitudine hand longiore, antrorsum fortiter 

 angustato, elytris seriebus punctorum solitis vix conspicuis, piceo-testa- 

 ceis, vitta obliqua a humero sensim dilatata et apicem totum occupante 

 ornatis, abdomine supra et subtus parce fortiter punctate ; antennis 

 elongatis basi obscure testaceis. Long. -33. 



Middle States ; rare. The tip of the last joint of the an- 

 tennae is piceous. The elytral stripe commences at the humerus, 

 and is gradually dilated to the tip where it extends to the suture 

 and external angle. The first dorsal segment of the abdomen is 

 smooth, the others are punctured like the ventral segments. 



107. B. longiceps. Piceus nitidus, capite nigro-piceo latitudine 

 plus duplo longiore, ore testaceo, thorace nigro latitudine haud breviore, 

 antrorsum fortiter angustato, margine basali pallide piceo; elytris serie- 

 bus solitis tripunctatis dilute piceis, limbo lateral! nigricante, abdomii^a 

 supra dilute piceo, fortiter parce punctato, pedibus testaceis, antennarum 

 articulo Imo piceo-testaceo. Long. *30. 



Lake Superior, one specimen. Related to the preceding, but 

 besides the differences in color, the head is less elongate ; as in 

 it, the first dorsal segment of the abdomen is smooth ; the others 

 are punctured like the ventral segments, which are, however, 

 darker in color. 



BRYOPORUS KRAATZ. 



1OS. B. flavipes. Nigro-piceus nitidus, antennarum basi pedibusque 

 testaceis, elytris seriebus punctatis setigeris, abdomine modice punctato, 

 helvo pubescente. Long. -17. 



Louisiana ; Dr. Schaum. The outer rows of punctures are 

 somewhat confused ; the thorax is not wider than its length ; the 

 four apical and four basal punctures are not very near the mar- 

 gins.
