Genus MACRANCYLUS LeConte

Macrancylus LeConte, Am. Phil. Soc., Proc. 14: 338, 1876.

Haloxenus Perkins, Fauna Haw. 2: 148, 1900. Synonymy by Champion, Ent. Mo. Mag. II, 20: 123, 1909.

This genus was described as American by LeConte, but I have shown in my "Synopsis of the Genera of Hawaiian Cossoninae " [B. P. Bishop Mus., 0cc. Papers 15(25): 285, 1940] that the genus belongs to the Pacific fauna and that the genotype of Haloxenus is a synonym of the genotype of Macrancylus . In other words, the genotype of Macrancylus is a Pacific insect that has been imported into America. The genus has remained monotypic until now, but the discovery of a new species on Guam indicates that there are more species to be found in the Pacific. [Since this was written, I have described a third species from Samoa (B. P. Bishop Mus., 0cc. Papers 16(7): 172-173, 1941)].
