After the emergence of males and new females, observed nest of Bombus (Pratobombus) ignitus Smith was excavated on September 6 and 13, 1959. In this paper are given some informations on the nest and its inhabitants. The nest contents are shown in Tables 1, 2, and 3. The nest was typical subterranean type. The wax envelope was not recognized on the entire surface of the comb. The cell group was arranged alternately. The color of bee wax was dark brown which is similar to it of Bombus ardens Smith. Many commensals and parasites were found in the nest. Especially, many larvae of Tinea simplicella Herrich-Schaffer, destroyer of the nest, were going on well in the nest. But a braconid parasite, Apanteles sp. (A), was confirmed by an experiment as a natural enemy of Tinea simplicella.
