46 HISTORY OF TIIE GENUS. 



1850. Boheman (K. Vet. Haudl. 1849) describes a Scymnus 

 from Gothland under the name bisignatus, which was 

 revived by Thomson in his Skandinavian Coleoptera. 



Leconte (Lake Sup. pp. 238 — 9) describes Oxynychus (n.g.) 



mcerens, Scymnus caudalis, lacustris, ornatus, and notes 

 26 species. 



At this point Mulsant's monograph of the exotic species 



appeared. 



1852. Leconte (Proc. Acad. Phil. vi. 129) describes numerous 

 species from N. America ; Htppodamia Mulsanti, am- 

 bigua, punctulata, Coccinella lacustris, Mysia Rathvoni, 

 Coccidula lepida, Exochomus Guexi, Hyperasjns militaris, 

 vittigera, arcuata, annexa, ^-vittata, consimilis, jucunda, 

 tamiata, pratensis, Oeneis puncticollis, pusilla, Scymnus 

 amabilis, guttulatus, femoralis, nebulosus, pollens, debilis, 

 ductus, suturalis, fraternus, licemorrhous, puncticollis, 

 socer, abbreviatus, nanus, punctum. 



He also makes some very valuable observations on the 

 limits of genera. 



1853. Mulsant (Op. Ent. ii.) describes thi-ee species from France. 

 Scymnus alpestris, anomus, Coelopterus (n. g.) salinus. 



Motschulsky (Et. Ent. ii.) describes Chilocorus rufitarsis 



from N. China. 



Mulsant (Op. Ent. m.) gives a long catalogue of additions 



and rectifications to his monograph. The new species 

 are for the most part from Deyrolle's collection, and are 

 rather hastily referred to their respective genera.
