Cynipid^. 
Reinhard has discussed the conditions of reproduction in the 
unisexual CynipidcB (Berl. ent. Zeitschr. 1865, pp. 1-13). He 
first refers to the various statements that have been made with 
regard to the occurrence of female specimens only in numerous 
species of Cynips and allied genera, and discusses the various 
hypotheses which have been proposed to explain the sexual 
relations of these forms, concluding with an exposition of the 
observations and hypothesis of Walsh (see Record, 1864, p. 468). 
He indicates, however, that from WalsVs own statements there 
is some possibility that there may be an error in his observations, 
especially as he admits a certain difference in the galls of Cynips 
spongifica and C. aciculatay which throws some doubt upon the 
accuracy of his data. Reinhard considers that there are at least 
two other possible explanations of the phenomena observed by 
Walsh, namely ; — 
1. C, spongifica may be an inquiline of C. aciculata'y or, 
3. C. spongifica and C. aciculata may be generically different 
gall-producers, giving rise to very similar galls. 
Cynips aciculata belongs to the genus Cynips, as restricted by Hartig ; 
C. spongi/lca is regarded by Reinhard as the type of a now genus, to which 
ho gives the name of Aniphibolips. In the superficial characters of the thorax 
this species seems to approach the inquiline genera Syiiergus and Onychia j 
in the venation of the wings it most resembles Ti'igonaspis. Hence it seems 
probable that C. spongifica is a true gall-fly ; and this view is strongly borne 
out by the circumstances of its development. Reinhard accordingly regards 
the second conclusion as the correct one.
