With his usual kindness Mr. C. A. Frost sent me the subjoined Heteroptera collected by him in Nova Scotia in July 1927 and 1929, at Portaupique and Westchester. The latest data available on bugs from this part are contained in Blatchley's Heteroptera of Eastern North America; the most extensive list thus far pubished is Parshley's 1923 paper, Records of Nova Scotian Heteroptera, which appeared in Proceedings of the Acadian Entomological Society for 1922, pp. 102, 108. The present records have been checked against these; the order of the species, for convenience, is that of Blatchley's Heteroptera.
