NORTH AMEKICAX LEPIDOPTERA. 133 



tinued so near tlie a])ex as in I), rjallii ; the apices show a very dis- 

 tinct hhick streak, absent in the European species. The central 

 fascia of the inferior wintrs is more suffused with rose color. The 

 basal al)doniinal segment is less l)lack laterally than in D. chamcenerii, 

 while I notice a few minor differences which are perhaps not con- 

 stant, as are those I have cited." 



Now, of all these there is but one feature constant, viz., the color. 

 The American specimens are more intensely colored and rather 

 smaller than the European examples, but otherwise I cannot find 

 any constant differences. In genital structure they are identical. 

 The greater intensity of color is a character of nearly all American 

 representatives of European forms. In the Noctuidse, European and 

 American specimens of the same species are nearly always separable 

 in this way. I would, therefore, retain the term chamcenerii to ex- 

 jjress a geographical form or race — hardly a variety, for in that case 

 all the American forms of European species must receive names. 



None of the American specimens I have seen reach the average 

 size of rjaUii, which has also proportionally longer and stouter an- 

 tennae. 



Harris, and after him, Clemens and Morris describe the larva in 

 general terms, as: "Green, somewhat bronzed, dull red beneath; 

 with nine round cream colored spots encircled with black on each 

 side, and a dull caudal horn." 



Prof Fernald states that the species is common al)out flowers near 

 Orono, Maine. It is rare sf)uth of Massachusetts.
