Aphilotrix fecundatrix. 47 



difficult to recognize, as its brown point scarcely shows 

 beyond the scales of the bud, but when mature it projects 

 more distinctly, and its base is gradually loosened from 

 the tissues of the bud-axis. Before it was known that 

 Aphilotrix collaris and Andricus curvator were alternating 

 generations, it was supposed that the Qgg laid by 

 Andricus curvator in June rested in the bud until the 

 next year, and that then, when the period of growth 

 returned, Andricus curvator galls were formed once 

 more on the leaves. This was all the more easy to 

 believe, because the bud in which the egg was laid in 

 June, rests until the next year as a winter bud, and 

 does not naturally develop in the same year. We see, 

 however, in this, as in other cases, that a dormant bud 

 may be induced to shoot by the larva. 



[The curved leaf gall is found in June, and sometimes on Lammas 

 shoots, on Quercus pedimculata, Q. sessiliflora and Q. pubcscais. 



Inquilines. Syncrgiis albipes, S. apicalis, S. facialis, S. radiatus 

 and 5. thaumacera in June of the same year; and Periclisttts Brandti. 



Parasites. Torynms auraiits, T. abdontinalis, Pteromalns cordairii, 

 P. tibialis, P. meconatus, P. Saxesenii, P. dissecius, P. Erichsoni, 

 P.jucundus, in June and July of the first year; Eurytoma gracilis, in 

 August ; Entcdon scianeiirus, E. cecidomycarmis, Eidophtis lacvissinius, 

 E. metallicus, Siphonura viridiaenea, Mcsopolobiis fasciiventris, Teh' 

 nonius phalaenarum, Decatoma biguttata, D. Nccsi, Eurytoma rosae, 

 Syntoniaspis dubitis, Pleitrotropis metallicus, Elachestits petrolatits, and 

 Eupehnus avinnlatus. The larva chambers of the Synergi are usually 

 near the surface and do not interfere with the gall-maker.]
