Of these twenty-two species, eight of which are introduced, 

 at least eleven are not likely to occur in Wisconsin, so that 

 the number of plants upon which the insect will probably be 

 found is very limited if, as is most probable, the plant really is 

 one of the Malvaceae.— C. V. Riley. 



Arrangement of N. A. Cynipid^e by Dr. Mayr. — I pub- 

 lished in the March Naturalist 1 a list of American Cynipidae 

 as generically arranged by Dr. G. L. Mayr, of Vienna. The list 

 contains less than half of our species, I think, and it does not in- 

 clude all that I sent to him. Several species differ from estab- 

 lished genera so far that they will probably form the types of 

 new genera. 



I was surprised to find that he recognizes but one American 

 species as belonging to the genus Cynips, for this genus contains 

 eighteen European species. His new genera, Acraspis, Loxaulus, 

 Holcaspis and Belenocnema arc, so far as known, exclusively 

 American. The last named genus is founded on a Floridian 

 species sent him by Mrs. Mary Treat. He describes it, and gives 

 it the name of the' discoverer, B. Treata. Loxaulus contains only 

 my C. q. mammilla, described in the Canadian Entomologist last 

 summer. Of the twenty-nine genera recognized by Dr. Mayr, I 

 have mentioned only those containing American species found in 

 his collection. Probably other genera will be found represented 

 here when our fauna shall have been thoroughly worked out. 

 The three Californian and the four Arizonian species which I 

 sent him, fall into European genera, while the seven species in- 

 cluded in the four new American genera, are all from the region 

 east of the base of the Rocky mountains.
