LEPIDOPTEEA. 
Boisd. (nec Herr. Schaff., whose type is aiigias, whereas Westwood’s type is 
jielasgus), Synemon^ Tascina^ g. n., and Ilecatesia. He excludes Othria, 
g. n. [= Ortkia, Herr. Schatf.], Damias, Burgena, Ilespagarista, and 
Rothia^ g. n., as Agaristidce ; and JEgiale Megathymus as Hesperiidce. 
The paper commences with a lengthy discussion on the obstacles to a 
correct classification of the Lejgidoptera^ with special reference to that of 
the Caslniidw, and observations on their neuration. Westwood rejects 
Boisduval’s sections, regarding only Castnia pelasg us, Cram. , as worthy of 
generic separation, and for this (p. 193) he incorrectly retains Herrich- 
Schaffer’s name of Orthia, which he thus separates from its type.
