In this memoir (which does not by any means exhaust my mate- 

 rial ) I describe in the subfamily Cynipkke three new genera: So- 

 lenosopherla, Eumayria and Bassettia ; and in tlie subfamily Figitince 

 several new genera. I liave separated the old genus Eiwoila Westw., 

 from the Fig'dinw as a subfamily {Eucoilinoe) with several well-defined 

 genera, and also describe new species in numerous Euroi:)ean genera 

 not before recognized in the North American fauna. 



The genus Solenozopheria is erected to contain a cynipid making a 

 reniform, pithy gall on huckleberry (Vaccinium') which cannot be 

 placed in any of the known genera. Indeed, this is the first instance 

 on record where a cynipidous gall has been found on a plant in the 

 Heath Family (^Ericacece), for in America, cynipidous galls have been 

 found only on the Oak Family (CupulifercB), genus Quercm; Rose 

 Family {Bosacece), genera Potentilla, JRubus and Rosa; Composite 

 Family ( C'o^nposike), genus Lygodesmia ; Mint Family (Labiatce), 

 genus Nepeta ; and Night-shade Family (Solanacea'^ genus Solanum. 



In Europe, cynipidous galls have been found in all the above 

 families but one, Solanacece ; and in all the genera but one, Lygo- 

 desmia ; besides in the following additional families and genera: 

 Maple Family (Aceracece), genus Acer; Poppy Family (Pjpaveracece), 

 genus Papaver ; and Grass Family (Grra.Himece), genus Triticum ; on 

 additional genera in Mint Family {Lahiatxz), genera Glechoma and 

 Salvia; in Rose Family (Rosacece), genus Sorb us ; in Composite 

 Family ( Compjosike), genera Hleracium, Scorzonera and Ceataurea. 

 Fi'om South America, a cynipid causing a gall on Aeacia farnesiana, 

 Dr. Mayr erected his genus Eschatocerus ; and from Africa, in the 

 Cashew Family (Anacardiacece), genus Rhus, his genus Rhoophilus. 



The above constitutes a complete list of the known food plants of 

 the Cynipidce; and the discovery of a cynipidous gall on a new 

 family of plants, belonging to a new genus, is doubly interesting.
