States were invariably larger and darker than those from southern 

 localities ; as there appeared to be two races or possibly species involved 

 it was necessary if possible to ascertain to which form Geyer's name 

 was applicable. The species was figured in the Zutraege, IV, Figs. 

 775-6 but unfortunately in the text the only locality given is "North 

 America" ; from the figure it is impossible to ascertain the minute 

 details, but we would note that the size of the figure is distinctly smaller 

 than that of the New York and Maine specimens ; it might also be 

 noted that a large proportion of Hubner's North American material 

 came from Georgia (presumably from Abbot's collecting) so that 

 there would be nothing out of the way in selecting this state as the 

 home of the species. 



Acutaria H. S. was figured in the Samml. Eur. Schmett., VI, 74, 

 Fig. 447, as a European species and as we have no access at present 

 to this work we have been forced to rely on Guenee's description and 

 figure, drawn up from two Georgia specimens (Sp. Gen., X, 233, PI. 

 17, Fig. 6) ; this figure is also poor but the size is small as was to be 

 expected from the locality given for the specimens. Hampson in his 

 Cat. Lep. Phal. B. M., XIII, p. 114, figures the large northern form 

 as bistrialis, having no southern material before him except Floridan 

 material which he has referred to spadaria Gn., his diagnosis of this 

 latter species corresponding with our own identification from a series 

 from Everglade, Fla. ; we imagine therefore that we are safe in fol- 

 lowing Hampson's citation of diz'isa Wlk. and promptella Wlk. to 

 spadaria Gn. especially as the size given by Walker for his types 

 distinctly points to their being large forms. 



As far then as our present knowledge goes we must apply the 

 name bistrialis Geyer with synonym acutaria H. S. to the small southern 

 form which in the S 's averages a wing expanse of 30 mm. and in 

 the 9 's about 34 mm. We have the form from as far north as 

 Southern Pines, N. C. (figured by us as bistrialis, Contr. I, (5) PI. 

 VIII, Fig. 19) and from various Florida localities (Ft. Myers, Dade 

 City, Glenwood) ; we imagine the Everglade specimens listed in Gross- 

 beck's List of Florida Insects (Bull. Am. Mus., 37, p. 66) under 

 bistriaria should be referred to spadaria; all our specimens collected 

 at the same time were this latter species. 



For the larger northern form we propose the racial name grandi- 

 PENNis (PI. XVII, Figs. 1, 2), our type series consisting of 7 S's
