Seven species of Philippine Armigeres and Armigeres subalbatus from Japan are discussed. In the adult stage Amigeres joloensis of the Philippines and Armigeres subalbatus of Japan have in common certain markings on the mesonotum and abdominal sternites, and the mesonotal markings are variable or unstable, easily rubbed in caught wild adults and therefore of no great value in routine identification. However, the markings on the abdominal sternites remain fairly intact even in badly damaged specimens, for which reason they are very useful in rpractical diagnosis. In the pupal stage there is no character of generic or subgeneric value, and the specific differences, except in Armigeres magnus, are slight. The pupae of Armigeres joloensis and Armigeres baisasi cannot be differentiated and the pupa of Armigeres subalbatus resembels both very closely. In the larval stage A. joloensis, A. subalbatus and A. baisasi are alike. Two well marked characters may be of generic and subgeneric importance if these are found to be true for all other Armigeres of the Philippines and other countries. In all species examined including A. subalbatus, the tubercle or plate bearing mesothoracic hair 8 is fused with the plate from which the mesopleurals arise and the tubercle of metathoracic hair 7 is fused with the plate of the metapleurals. In those species belonging to the subgenus Armigeres including A. subalbatus mesothoracic hairs 5, 6 and 7 arise from a common elongated plate true also in A. breinli as drawn by Belkin 1962, but in the species in the subgenus LeicesteriaLeicesterio-myia, these mesothoracic hairs arise separately from small plates.
