1. New localities are added to the distribution map of Neope niphonica kiyosumiensis TAKAHASHI et AOYAMA in the Boso Peninsula, which was showed in the first report (TAKAHASHI and AOYAMA, 1981). 2. Adults of the spring and the summer form emerge earlier and later respectively than those of the nominate subspecies niphonica. Delay of adult emergence in the summer generation probably occurs as a result of the pupal diapause in the summer. 3. The present subspecies is distributed in cooler areas of the Boso Peninsula. The distribution is possibly limited by rather high temperature during the summer. 4. This subspecies occurs in deciduous broad leaved forests with the shrubbery of Pleioblastus, Bambusaceae, at the foot of mountain, on the hill side, at the river side, etc. 5. Pleioblastus chino, Bambusaceae, is the most common larval food plant. Eggs and larvae were found on the underside of the leave. 6. Adults suck the sap of the deciduous broad leaved trees, mainly Quercus acutissima and Q. serrata. Scarecely, they are seen drinking the water on the ground. 7. The spring form adults fly all the day. Some males behave territorially around the tip of branch or the tree trunk, while others continue to fly up and down around the tree trunk. Those males probably search for mates. The summer form adults fly actively in the evening, but they stay on the leaves of under-growth from late morning to early afternoon. The males fly similarly to those of the spring form, though the flight is slower and the up-down flight is less conspicuous. 8. Females lay eggs in batches with several to more than twenty eggs. 9. We speculate that Neope niphonica kiyosumienses might be differentiated from the nominate subspecies during the Riss-Wurm inter-glacial period in the Pleistocene.
