52 THE CANADIAN ENTOMOLOGIST. 



on the surface of the earth in a slight cocoon, and the imago appears in 

 about ten days, except the last fall brood, which hybernates in the chry- 

 salis." 



I have, as stated in a former number of the Can. Ent., also received 

 specimens of it from Texas. And G. cilhclineaella only differs by the 

 white lines at and in the uliae. 



G. Hefmannella. 



In vol. 4 I have copied from the Nat. Hist. Tin. a description of this 

 species ; and in The Ento. Mo. Mag., v. it, p. 279, I have given an 

 account of a variety found in Kentucky and Missouri, and probably fur- 

 ther south, which I copy here for the benefit of American readers and for 

 the purpose of adding some additional particulars. The specimens of the 

 variety which I have bred — something over twenty — were from larvae taken 

 at various localities in Kentucky, and all that I have captured in Kentucky 

 belong to the variety likewise, and Miss Murtfeldt writes to me from St. 

 Louis that the variety only has been bred there. If the old, well-known 

 form occurs at all in this latitude, it must be very scarce. 



" .So far as I can learn, no variety of this species has yet been found in 

 Europe, though the species occurs from Lapland to Naples. Some three 

 years ago I found the larvae mining leaves of Chenopodmm on the shore 

 of Lake Michigan, lat. 43 deg. N. ; and from them I bred several speci- 

 mens differing in no essential particular from the figure in Nat. Hist. Tin., 

 v. ix., plate 8. Afterwards I often found them mining the same leaves in 

 Northern Kentucky, lat. 38 deg. (nearly), but as I had as many specimens 

 as I then wanted, and never thought of a variety, I did not attempt to 

 breed them until the summer of 1874. The larva was the same, the mine 

 was the same, and the mined leaves were of the same plant that I had 

 found in Wisconsin, but, to my surprise, all the specimens that I have 

 bred differ so decidedly from the ordinary G. Hermannclla that probably 

 any Entomologist would have considered them, if only captured, as of 

 distinct species. Yet a little ingenuity on comparison of the specimens 

 will show how the one pattern of ornamentation is readily resolvable into 

 the other. One who knows this 'micro,' or the figure of it before men- 

 tioned, will remember the silvery fascia dark-margined on both sides, the 

 small silvery spot before the fascia beneath the fold, and the larger one 

 just above the fold behind the fascia. Now, suppose the dark margins 

 of the fascia increased in quantity, especially the posterior dark margin
