54 ENTOMOLOGICAL NEWS. [March 



began to appear May 23, and continued to do so in consider- 

 able numbers for several days. 



On June 24 my assistant visited the vineyard from which 

 the leaves had been taken, and found a large number of galls 

 on the new growth of cane, and within these galls were larvse 

 of considerable size. The same vineyard was again visited 

 by myself on August 11, when all stages of development ex- 

 cept the egg were found within the galls, the larvae now being 

 all of them nearly or quite full grown, while some of the 

 adults were observed in the act of making their way out from 

 the galls. I visited this vineyard again on September 15, and 

 could then find only a single pupa (a), after long and patient 

 searching, this being in a gall in the latter growth of cane, all 

 other galls, except for parasites, being entirely empty. A 

 later examination, made early in November, revealed not a 

 single adult in the galls, but a solitary one (a, b) was discov- 

 ered among the fallen leaves, where it was probably in hiber- 

 nation. In this series of observations it seems to me that we 

 have conclusive proof that in Northern Ohio at least the species 

 is single brooded, the adult wintering over among fallen leaves 

 and other similar rubbish, coming forth in Spring in time to 

 begin oviposition in the earliest growth of cane. The greater 

 abundance of galls in the earlier growth of cane points to the 

 fact that the adults are abroad in numbers, and ready to begin 

 oviposition, as soon as there is sufficient growth of young cane 

 to afford them the necessary nidus, and while the period of 

 oviposition for the species in any one locality may be, and 

 probably is, considerably protracted, though, as previously 

 shown, the season of development is over by the first of 

 October. 



From within the galls I have taken pupae from which a par- 

 asite, Catolaccus tylodermce (h), known to also attack the larvae 

 of Tylodermce foneolatum, was also reared,aud also pupae {g) of a 

 small fly, Myiophasia cenea (/). Of three of these latter pupae, 

 two gave me adult flies, while the third developed a secondary, 

 hymenopterous parasite (i), Calyptus tihiator. 



As the locality where these observations were made is fully 

 three degrees of latitude north of St. Louis, Mo., it is quite 

 possible that there may be a considei-able difference in the 

 habits of this species, and t^is seems all the more likely from
