The specimens were examined at the Institute of Veterinary Research in Anyang, Korea R. and were identified as Rhipicephilus sanguineus (Latreille 1806). The morphological characteristics observed by means of the scanning electron microscope were presented with some SEM microphotographs. As R. sanguineus was firstly discovered to occur in Korea R, a total of 20 species of ticks belonging to 8 genera such as Argas, Amblyomma, Boophilus, Dermacentor, Haemaphysalis, Hyalomma, Ixodes and Rhipicephalus has now been recorded

A migratory bird, the white stork Ciconia boyciana was captured from a pond in the Chejudo, Korea R. on the 18th of Dec. 82. The morphological characteristics were described as seen in the binocular stereoscopic microscope and further fine structures were observed by means of the scanning electron microscope (model; ISI-DS-130). The bird was examined for ectoparasites at the Cheju Provincial Veterinary Research Lab. Two kinds of specimens were collected from the head and body feathers. The specimens were sent to the Inst. of Veterinary Research in Anyang, Korea R. for classification and identification

Scanning electron microscope (model; SEM ISI-DS-130) was used to observe the fine surface structures of the predominant cattle tick Haemaphysalis longicornis Neumann 1901 (Acarina; Ixodidae) in Korea R. and some SEM microphotographs were presented in this pictorial monograph. A total of 18 photographs was selected from the numerous SEM photographs of the female and male specimens of H. longicornis for the observations of the fine surface structure and the comparison between the female and male structures
