which overlap somewhat, some of those of the earHer cycle living until 

 after the appearance of those of the later one, and in some instances mating 

 with them. 



Upon this hypothesis the larvae which hibernated direct from the 

 egg would all start feeding at about the same time and so would account 

 for a simultaneous appearance of many fresh specimens about the 

 beginning of August, while those which emerge over a considerable time 

 in the early summer would be from those larvae which had passed one or 

 two moults the previous year. 



Mr. Edwards's later view, that there are probably two broods in 

 Virginia, the one descended from the other, I hold to be untenable in 

 view of the long egg period, even in the heat of early August. Nor am I 

 inclined to accept as probable the suggestion of Mr. Scudder, based upon 

 the experience of Vaudouer in the case of the European EupJwosyne^ of 

 a lethargic period in the case of that portion of the brood which does not 

 reach the imago state till August. 



I hope to pursue my experiments farther, and to that end appeal for 

 the assistance of other lepidopterists, and will gladly pay, either in money 

 or exchange, for living specimens of the female of this species sent me 

 not later than the first week in July. These can be sent by mail in 

 suitable boxes addressed to me at 384 St. Paul St., Montreal. 



TRYCHOSIS TUNICULA-RUBRA, N. S. 



REV. THOMAS VV. FVLES, SOUTH QUEBEC. 



While studying the habits of Gelechia gallcz-diplopappi^ I have 

 repeatedly met with a parasite, in the galls of the moth, that I have not 

 found elsewhere. 



I have submitted imagos of the species to several of our most 

 eminent hymenopterists, and all agree that the species is new to science 

 and undescribed. To Mr. Ashmead I am indebted for the information 

 that it will properly come into Foster's genus Trychosis. 



The full-grown larva of the species is a fusiform, legless grub, three- 

 tenths of an inch long, and having thirteen segments, counting the head. 

 The anal segment is somewhat elongated. The creature is of a white 

 waxen appearance, with a tinge of pink ; and it has a few short hairs on 

 its face and along the back and sides. The spiracles are well defined. 

 On the ventral surface of the grub are a number of extensile and retractile 

 pads or pseudopodia, by the aid of which it fastens itself to its victim, or
