6 THE CANADIAN ENTOMOLOGIST. 



Several galls (2-10) are often found together in a cluster on the same 

 rootstalk. 



Miss Clarke slates that the galls are rather abundant, but not easily 

 observed on account of their location, the more so as the Asfers normally 

 grow in the grass-sod, where it is not easy to dig. 



Miss Clarke sent me a few of these galls in August ; I asked her to 

 get more, and, with her usual enthusiasm. Miss Clarke made a special trip 

 to Boston from her summer residence and secured about 150 additional 

 galls, which, during the first two weeks in September, produced a large 

 perfect series. 



Gnoritnoschema gallcEasieriella Kellicott. 



In Vol. XLI, p. 75, 1909, of The Canadian Entomologist, the late 

 Dr. Wm. Brodie, of Toronto, maintains that this name is a misnomer (he 

 has it wrongly as asterella Kellicott), and that Kellicott was mistaken in his 

 identification of the food-plant. Dr. Brodie even asserts that he can 

 recognize Kellicoti's woodcut of the gall as Solidago iatifolia, not as 

 Aster coryinbosus. 



In this I cannot agree with Dr. Brodie ; Kellicoti's figure may at 

 least as well represent Aster as Solidago, and there is no reason to doubt 

 that Kellicott did breed his species from Aster, as it has been bred 

 repeatedly since from that plant. I have before me specimens from Miss 

 Clarke, which were unquestionably bred from the white wood-aster, Aster 

 divaricatus Liss. ( corymbosus Ait.), near Boston. 



On the other hand, I have many perfect specimens bred by Dr. 

 Brodie and by Mr. A. Cosens, of Toronto, which, according to both these 

 gentlemen, were bred from Solidago Iatifolia and S caesia, and the species 

 would thus seem to infest both Aster and Solidago. 



ON THE GENUS MASTOR, GODMAN AND SALVIN. 



BY KARL R. COOLIDGE, PASADENA, CALIFORNIA. 



Godman and Salvin, in the Biologica Centrali-Americana, Rhopalo- 

 cera. Vol. 2, p. 567, 1893, erected the genus Mastor for the reception of 

 three species, Painphila ( Hesperia) bellus Edward;;, and two new species, 

 M, perigenes and M. afiubis, the latter being named as the generic type. 

 Mastor is characterized as having the primaries fairly short, truncated 

 somewhat apically, in this respect approaching Poanes and PoaJiopsis, from 

 which it differs in a longer crook to the antenncie, the club slenderer, and 

 the primaries less rounded at the tip. The third joint of the palpi is short
