CUERENT NOTES.— No. 2.

 (Continued from p. 264.) 



To W. F. FiSKE (2) we are indebted for an extensive study of 

 the hymenopterous parasites of CUsiocampa americana. Primary 

 parasites, hyperparasites of the primary ones, secondary para- 

 sites, and hyperparasites of the secondary ones, are all discussed 

 at length. " In the beginning of the series of collections and 

 breedings it was supposed that the parasites would be found to 

 exert considerable influence on the prevailing numbers of their 

 host ; that is to say, in the case of CUsiocampa americana, for 

 instance, that the parasites would be found to be one of the more 

 important of the factors which governed the abundance of this 

 species from year to year. But investigation failed to confirm 

 this theory. ... In 1896 it was exceedingly common, . . . and 

 it was consequently assumed that its parasites would also have 

 increased to such an extent as to be a considerable factor in 

 bringing about a more normal condition in 1897. But, strangely 

 enough, this reasoning was found to be diametrically opposite to 

 the facts of the case. In 1896 a great many caterpillars were 

 destroyed by Limneria fugitiva, and numbers of the characteristic 

 cocoons of this species were collected and bred. . . These proved 

 to be in their turn almost entirely the prey of Pimpla inquisitor, 

 and the breeding-cages in which the cocoons were confined be-
