Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1916 edition. Excerpt: ...structural characters: Eyes bare. Male with two rows of frontal bristles, and with reclinate fronto-orbitals. Female with one row of frontals, and both proclinate and reclinate fronto-orbitals. Third antennal joint hardly as long as second. First aristal joint not elongate. N o discal macrochaetae on intermediate abdominal segments; male with marginal row of second segment normally complete, female with same interrupted laterally; marginal rows very thickly set; anal segment covered with spines that are nearly as heavy. Female front tarsi greatly widened. Owing to the fact that a number of closely similar forms exist in the eastern and southeastern United States, it is impossible to identify this species with any of the various superficial descriptions of Drury, Desvoidy, Macquart, or Jaennicke. Williston was the first to describe the form by recognizable 73 characters. The scutellum and abdomen, especially the latter, are polished rufocastaneous; mesoscuturn blackish, subshining, thinly brassy pollinose; wings lightly infuscate, blackish at base. Okea, new genus. Genotype, Winthemia okefenokeensis H. E. Smith, 1916, Proc. Ent. Soc. Wash., XVIII, 95, Okefenokee Swamp, Georgia.. Difl'ers from Winthemia as follows: Male. Front broader; antennae longer and more slender, the second joint well elongate. Venter of preanal segment with strongly marked pilose areas; the pile long, thick, and rather coarse. Second to fourth front tarsal joints each widened into oblique transversely elongated pieces, these joints being wider than their length, set obliquely and well separated. Hind tibia: thickly ciliate, without conspicuous longer bristle in middle. There are normally no median macrochaetae on first two abdominal segments. Hypopygial forceps...show more
