Photo from life (x 2.3) of two Spelerpes larvae wdiich were kept in 
0.05% resorcinol for seven days, beginning just before pigmentation started. 
Their heavy form and the peculiar pigmentation readily distinguish them 
from the accompanying check. The photograph w r as taken thirty days 
after the larvae were removed from the resorcinol solution.
