2 NEW SPECIES OF DIGGER WASPS OF THE GENUS BELOMICRUS (HYMENOPTERA, SPHECIDAE) FROM THE SOUTH-EASTERN KAZAKHSTAN

Two new species of Belomicrus A. Costa, found in the valley of the Ily River are described. Both species belong to kohlii group (= Oxybelomorpha Brauns), characterized by coming together (to midface) internal edges of the eyes, existence (as a rule) of a denticle on the lower edge of mandibles, protrudence on the intermediate segment, absence of a tuber on the temples supraorbitally and rather small sizes of the body. B. tricolor Kazenas, sp.n. differs from the similar species by a narrow (see laterally) tuber of the inermediate segment, yellow aspidate and rich light-colour pattern of the abdomen; B. iliensis Kazens sp.n. - by a thin and rather large dotting of the mid-spine and scutellum, by abdominal pattern (having, as rule, one interrupted or contracted belt on the first tergum), by peculiarities of the structure and colouring of postscuteller scales and less developed denticle on the lower edge of mandibles.
