W. – First descriptions of queens of seven of Myrmica ant species and males of four of these species are given. The species were first described between 1865 and 1947 from workers. They form part of the distinctive Himalayan Myrmica fauna that inhabit the south-western slopes of the Himalaya.

Três espécies de Pison Jurine, 1808 (Hymnoptera: Crabronidae) coletadas em Rio Claro (SP), Brasil

Abstract: The genus Pison Jurine (in Spinola), 1808 (Hymenoptera: Crabronidae) was revised by Menke, 1988 and three subgenera were placed in synonymy with Pison: Pisonoides F. Smith, 1858; Krombeiniellum Richards,1962 and Entomopison Menke, 1968a. The genus includes 42 native species in the Neotropical Region and more of the half of these are found in Brazil. Some of them make mud nests on diverse substrates, such as: on the underface of broad leafs, on the wall of human constructions, boxes, windows, and in the edges of roofs. The coccons of some of these species are closed cells with a fine layer of mud in a small abandoned nest (made on vegetable fibres) of Mischocyttarus de Saussure, 1853 sp. (Hymenoptera.: Vespoidea, Vespidae, Polistinae, Mischocyttarini). This is the first record of nesting behavior for this species. Male of P. duckei is still undescribed. The third specie observed was P. delicatum Menke, n sp
