Abstract
Fraenkel and Rudall1 found that, when mature Sarcophaga larvæ were immersed in methanol, cuticular darkening occurred within a few days ; ethanol was ineffective, but propyl, butyl and amyl alcohols were somewhat active. Dennell2 found a more rapid darkening in methanol and a slight effect with ethanol, and suggested that methanol broke down some inhibitor which normally prevented darkening until the onset of pupation. This communication deals with the effects of injecting alcohols into Calliphora erythrocephala (Meigen) larvæ.
