NEW SPECIES OF AI^IEKICAN SCOLYTOID 

 BEETLES, MOSTLY NEOTKOPICAL 



By M. W. Blackman ^ 



In the following pages 1 new genus and 29 new species of bark- 

 beetles are described, the genus and 3 species from the United States 

 and 26 species from Neotropical countries. Of the latter, 12 species 

 are from Central America, 4 species from the West Indies, 3 species 

 each from Colombia, Bolivia, and Argentina, and 1 species from 

 southern Brazil. 



The species here treated do not belong to a single restricted group 

 of the Scolytoidea but represent a number of genera in several more 

 or less distantly related tribes or subfamilies. The groups concerned 

 are Bothrosternini, Camptocerini, Hexacolini, Hylesinini, and 

 Phloeotribini. All drawings for the plates w^ere made by Arthur 

 D. Cushman. 



Genus CNESINUS LeConte 



The genus Cnesinus was described by LeConte, 1868, to include his 

 species C. strigicollis from Illinois. Since then about 20 species have 

 been described from Central and South America. Apparently many 

 additional species are still undescribed. In the present paper 8 new 

 species are described.
