Notes on New England Acrididae. —III. Oedipodinae. —IV

Taxonomic notes on Pternoscirtapulchripes Uvarov, 1925 (Orthoptera: Acrididae: Oedipodinae) with proposal of new synonyms in the genera Flatovertex and Mioscirtus.

Based on the examination of types and additional materials, the morphology of Pternoscirtapulchripes Uvarov, 1925 and Flatovertex species were reviewed. As a result of our study, the genus Flatovertex Zheng, 1981 was synonymized with the genus Pternoscirta Saussure, 1884, the species Flatovertex cyaneitibialis Zhang & Han, 2010 was synonymized with Pternoscirta caliginosa (Haan, 1842), Flatover...

Notes on Galois Theory III

Clearly F ≤ EH ≤ E. On the other hand, given an intermediate field K between F and E, i.e. a subfield of E containing F , so that F ≤ K ≤ E, we can define Gal(E/K) and Gal(E/K) is clearly a subgroup of Gal(E/F ), since if σ(a) = a for all a ∈ K, then σ(a) = a for all a ∈ F . Thus we have two constructions: one associates an intermediate field to a subgroup of Gal(E/F ), and the other associates...

Molecular Evidence for an Old World Origin of Galapagos and Caribbean Band-Winged Grasshoppers (Acrididae: Oedipodinae: Sphingonotus)

Patterns of colonization and diversification on islands provide valuable insights into evolutionary processes. Due to their unique geographic position and well known history, the Galapagos Islands are an important model system for evolutionary studies. Here we investigate the evolutionary history of a winged grasshopper genus to infer its origin and pattern of colonization in the Galapagos arch...

Notes on Some Remedies. VII. Sulphonamides. III

6. Urinary tract infections.?In acute cystitis and pyelitis and in chronic infection due to coli bacilli sulphanilamide is adequate but sulphacetamide has been particularly recommended because of its high solubility in urine. Its sodium salt (albucid soluble) may be injected intravenously in 30 per cent solution. Sulphathiazole or sulphadiazine may be given in resistant cases. The average daily...
