Figure 1. 



Photo from life (x 2.3) of two Spelerpes larvae which were kept in 

 0.05% resorcinol for seven daj^s. beginning just before pigmentation started. 

 Their heavy form and the peculiar pigmentation readily distinguish them 

 from the sccompanying check. The photograph was taken thirty days 

 after the larvae were removed from the resorcinol solution.
