In regard to this synonymy I would say that I have examined 
specimens referred to these names by the authors in the works 
cited. 
Scudder described this species from 4 J* and 4 ? specimens 
from Texas, stating tliat he had smaller specimens from Vermont 
and Massachusetts, and separated from it as another species 
{balteatum) a form described from 1 $ from New Jersey and 9 
9 from Maine, Vermont, Maryland, and Texas, in which the tips 
of the wings were less infuscated. He noted also a difference in 
the heiglitof the crest of the pronotum. 
From an examination of the specimens before me and from 
observations taken in the field in the past two seasons I ain forced 
to consider that these two foi-ms, — as represented in New Eng- 
land, at least, — are but one species, and that balteattim is 
unworthy even of varietal rank, a position to which Saussure 
assigns it. My reasons for so thinking are these: (1) There 
are no structural differences in the two forms, but the pronotal 
crest is higher in the ^ than in the 9 and varies somewhat in 
different individuals of the same form; (2) The two forms inter- 
grade in wing infuscation ; (8) Both forms are taken in the same 
spot at the same season of tlie year; (4) The greater proportion 
of the males have the wings as described for bolli and the greater 
j)roportion of the females as described for balteatum; (5) Two 
other New England species have the wing-tips of the males much 
more constantly and heavily infuscated than those of the females. 
These statements are based on nearly one hundred and fifty 
specimens personally collected in various parts of New England, 
a lot of 13 (J, 9 9 from one spot in Norway, Me., one of the 
localities from which balteatum was described being of interest in 
this connection, and also similar lots of 12 c? » 7 9 fi'om Fryeburg, 
Me., and of 19 J* , 17 9 from a locality in Connecticut. In 
addition to these 1 have examined a considerable number of
