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. CNESINUS CUBENSIS, new species Plate 15, FiGxmES 1, 2 Dark reddish brown ; 3.0 mm. long, 2.5 times as long as wide ; allied to strigicollis LeConte but larger, elytra with setae stronger, and de-clivity strongly retuse, 1 Dr. Blackman died on October 12, 1943, while this paper was in press. — Editor. 546425—43 1 371
