Results of the study of specimens collected in tropical Africa and preserved in different European collections and museums are reported and extensively illustrated. The following three new species are described: Horatosphaga aethiopica sp. n., Dapanera occulta sp. n. and Cestromoecha laeglae sp. n. In addition, new diagnostic characters or distributional data for Ruspolia differens (Serville, 1...

A critical and annotated catalogue of 72 types of Chrysididae (Hymenoptera) belonging to 53 species and subspecies housed in the Swedish Museum of Natural History is given. The lectotypes of Chrysisdiversa Dahlbom, 1845, Chrysissoror Dahlbom, 1854, Chrysurasulcata Dahlbom, 1845 and Holopygaamoenula Dahlbom, 1845 are designated. The previous lectotype of Chrysisdiversa Dahlbom, 1845 is set aside...

Let f be a primitive (holomorphic or Maaß) cusp form of level q and nontrivial nebentypus. Then for Re s = 1 2 the associated L-function satisfies L(f, s) q 1 4 − 1 1889 , where the implied constant depends polynomially on s and the archimedean parameters of f (weight or Laplacian eigenvalue). Résumé. Soit f une forme modulaire cuspidale primitive (holomorphe ou de Maaß) de niveau q et de carac...
