58 R. OSTEN SACKEN. 



ent kinds, on the other, different species of CnUhnome are occasionally 

 bred from galls of the same kind. Thus, both C hrcvicauda and C. 

 advena were obtained from the gall of DiuHfrophus nebidosux^ 0. S. 

 C. magnljica and C. fiavicoxa (perhaps also C. solitaria), were bred 

 from the gall of Rhudites radicum. 



Considerable materials for the present paper I owe to the communi- 

 cation of Mr. Norton, who had obtained a large number of Callimome 

 from galls on the rose. 



As, owing to the difficulty of this genus, doubts may arise concern- 

 ing the identification of some of my species, I have deposited the types 

 of my descriptions in the Museum of Comparative Zoology in Cam- 

 bridge, Mass.
