15S THE ( \N.VDl.\N ENTOMOLOGIST. 



Sept. 25, 1893, collected on wooded hill in St. James's cemetery, four 

 galls from upper third of S. ceasia stems, immediately below flowering 

 panicle, some galls leaf bearing. 



The largest of the four was ox 27 mm., and this one had a prepared 

 and plugged exit, from which there emerged next day a badly-deformed 

 little moth, suspiciously like G. asterella, the only producer from this gall 

 I have seen. Parasites the following spring. 



Sept. 1 8, 1896, collected on wooded hill, north of Toronto, from 

 stems of S. ceasia growing where galls of G. asterella were common, on 

 stems of S. lati/olia. These galls had not prepared exits ; were parasit- 

 ized, parasites emerging the following spring. These galls are very rare 

 about Toronto ; in structure they resemble galls of G. asterella, but are 

 less in size and not so inflated in form, and as I have always found them 

 where galls of G. asterella were common, and as the solitary deformed 

 specimen I had somewhat resembled G. asterella, there is a suspicion that 

 the 6". ceasia gall is produced by G. asterella. I regret I have not been 

 able to determine this. It is for some other worker to do. However, in 

 my notes I have entered as a provisional name Pcedisca ceasiella. These 

 four, Gnorimoschema galltesolidaginis, Riley ; G. asterella, Kell.j Eucosma 

 Scudderiana, Clem.; Stagmotophora ceanothiella, Cosens; with two doubt- 

 ful, one on S. ceasia, the other on A. corymbosus, are the lepidopterous gall 

 producers I have found in the vicinity of Toronto. But there are at least 

 five species of inquiline moths, more or less common, three from Diplosis 

 galls and two from Cynipid galls. 



Stagmotophora ceanothiella, Cosens. — The Ceanothus gall. 



In the autumn of 1880 I enjoyed holidays in the township of Carden, 

 Victoria County, where I found the shrub, Ceanothus Americana (New 

 Jersey Tea) common. I also found the galls common ; they appeared to 

 be from a deformed terminal bud, having some resemblance to a gall 

 terminal on twigs of Rosa blanda. I collected a number of the galls, kept 

 them outside during the winter, and on May 20, 1881, the gall producers 

 began to emerge, exquisitely beautiful little plume moths, probably the 

 first time human eyes ever looked upon these lovely little gems. 



In September, 1887, a collection of galls was made from the tips of 

 stems and branches of Ceanothus, some distance east of Toronto ; the 

 producers emerged the following spring, May 25, 1888, and two species of 

 parasites a few days later. 



Sept., 1890, the galls were on rank growth of Ceanothus in the town- 

 ship of Whitchurch ; found also at Grimsby and Essex. From this
