Mountains (Dr. Palmer); Guatemaua, Capetillo, Duefias, Purula, Quiche Mountains

Prof. Uhler? remarks, and apparently with excellent reason, “sufficient acquaintance 
with the nature of this form may establish it to be the form of L. turcicus dependent 
upon the tablelands of South-western North America.” It varies in sometimes having 
the membrane spotted with white. J. turcicus, Fabr., is a species at present restricted 
to North America, contingent on L. costalis, L. reclivatus, and L. kalmii not being 
shown to be but southern varieties of it. 
2. Lygeus reclivatus.

That this is but a form of L. turcicus appears to me extremely probable; and I follow 
Stél and Uhler in considering it distinct with much doubt and hesitation. | 
Prof. Uhler, in Hayden’s ‘Survey of Montana,’ writes:—‘‘The form described as 
L. reclivatus, Say, differs from the Fabrician only in having two white dots on the 
membrane. As specimens with this peculiarity occasionally hatch out of a cluster of 
egos of the L. turcicus laid on the pink Asclepias in Maryland, I do not hesitate to 
place it as a synonym of that species.” ‘This appears conclusive; but it was written in 
1872, and the same author?® subsequently treats the two forms as distinct species, 
remarking, however *, “This form is placed apart provisionally from ZL. turcicus, Fabr., 
merely because the full history of the species has not yet been elaborated.”
