Abstract
The larval st ages of the ri ffle beetl e Hydora annectens Spangler and Brown are described and illustrated for the first time. The y are compared to Hydora larvae f r om New Zealand . A key to the lar vae of the Ne w World genera is giv en. The distribution of known species o f Larainae is synopsized and a checklist of gener a an d species is given.References
