The writer publishes his experiments on 23 species of Cynipidce, giving 
full descriptions and particulars of their life-history and alternation of 
generations. Most of these exhibit differences in the sexual and asexual 
broods (which appear at different seasons), hitherto considered generic. 
Several forms are described as new, and will, for convenience of reference, 
be here also treated as new species. The 23 species noticed are as follows, 
the alternate brood being added in the second column. 
I. Neuroterus group.

2. N. Iccviusculus, Schenk, = S. albipes, Schenck. 
3. N. numismatis, 01., = S. vesicatrix, Schindl. 
4. N. fumipennis, Hart., = S. tricolor, Hart. 
II. Aphilothrix group.
