 note = {The structure of the occipital region in the Pierid butterflies mainly from Japan was observed. As the result, Leptidea was separable from the other species by the form of occipital prominence. The others were divided into 2 groups and 4 subgroups. Catopsilia resembled very closely Pierinae while Aporia and Anthocharis are very similar to Coliadenae in the occipital structure., Article, Journal of the Faculty of Textile Science and Technology, Shinshu University.
