Melanagromyza trapezoidea sp. n., M. asymmetrica sp. n., M. cuprea sp. n. and M. pratensis sp. n. are described, and a key to Melanagromyza species known to occur in Ukraine is provided.

A new genus of family Agromyzidae (Diptera), Epidermomyia is being described to receive one of the three groups of Tropicomyia sensu stricto described by spencer (1973) when he erected the Genus Tropicomyia . Comparaitive study of the larval and adult characters of the new genus and the genera Tropicomyia Spencer and Melenagromyza Hendel is also given. Keys for the identification of the six genera of sub-family Agromyzinae viz., Agromyza, Japanagromyza, Epidermomyia, Melanagromyza, Tropicomyia, and Ophiomyia along with listing of species so far described from India are included in this paper.

The 29 species of the subfamily Agromyzinae in Thailand are revised, among these 13 species are described as new to science: Melanagromyza ancyla sp. nov., M. catalexis sp. nov., M. cirrappendicula sp. nov., M. lunulata sp. nov., M. macilenta sp. nov., M. multistriata sp. nov., M. pandiculata sp. nov., M. sexseriata sp. nov., M. spinuliloba sp. nov., M. turgida sp. nov., Ophiomyia flagellata sp. nov., O. quadrifida sp. nov., O. striata sp. nov.; and nine species (three species of Agromyza, two of Melanagromyza and four of Ophiomyia) are recorded as new to Thailand. One new synonym is established: Melanagromyza cordiophoeta Spencer, 1961, as a junior synonym of M. dolichostigma Meijere, 1922. Keys to the Thailand species of the genera Agromyza, Melanagromyza and Ophiomyia are given.

During the summer of 1926, while collecting in Orillia, numerous small flies were observed on old fence posts in the hot sun. It was presumed that they represented some common species of Agromyzinae and only six specimens were captured after much difficulty, four of these proving to belong to a beautiful undescribed species of Mallochiella. In Melander's key to the Milichiinae (Jour. N. Y. Ent. Soc., XXXI, 1913) the members of this genus trace to Hypaspistomyia Hendel, an Asiatic genus, but the oral margin is not retracted. The carinate lunule is variable both in size and color in M. halteralis Coq. but always separates the antennae.
