Denver, June 10th on cottonwood (John Tobias). 
In regard to the above record Cockerell (in litt.) says:—“The Wet Mountain Valley 
salicis recorded by me, was not true salicis but ortliolobis var.” 
Regarding the species ortliolobis and salicis Cockerell (in litt.) further.says:—“If you 
look at Comstock s descriptions you will find that he alludes to a difference in the 
position of the median lobes of ortliolobis and salicis. 
Ortliolobis has these lobes close together (see figure), 
whereas salicis has them divergent (see figure). Now we 
have a specimen of ortliolobis from California, from Mr. B. 
W. Griffith, which shows the lobes close together as 
Comstock describes. But your Denver species show them 
wide apart, as in salicis. Yet your Denver scales are like 
the Nebraska ortliolobis (see my article in Can. Ent.) to all 
outward appearance, and are not like salicis. But at this 
point we prepared some English salicis, from Mr. Newstead, 
and they have the lobes close together as in ortliolobis. 
All this seems rather to confirm what I have suspected for some time, that the so-called 
salicis of this country \s not salicis at all, but a distinct species. If so, the synonymy of 
the species discussed will probably stand thus: 
(1.) C. salicis (L). Europe. 
(i.) C. ortliolobis Comst. U. S. 
(3.) C. salicis-nigrae (Walsh.) U. S. or ‘equals ’salicis Comst., not L. 
It is by no means clear, however, that your Denver scale is specifically distinct from 
the Nebraska one, which we are calling otholobis (vide. Can. Ent.) and as it is certainly 
not true European salicis, I should advise you to call it C. ortliolobis var. for the present.”
