110 NEUROPTERA. 
A.N.S.: 6 g), Top Range 11,000 feet [1 3], and San Gerénimo (Cockerell, P. P. C. 
det.), Zuni (Henshaw : 2 3 ), Merino valley (Palmer: 43) (M. C. Z.), all in New Mexico. 
Like the preceding, this species will doubtless be found in elevated localities in 
Mexico. 
As in E. cyathigerum, there is individual variation in the shape of the pale postocular 
spots, their posterior edge being either entire, crenate, or denticulate, and of the 
black spot on segment 2. 
A number of females from the same localities as the males of E. cyathigerum 
and E. calverti are before me, but I am unable to identify them more exactly ; 
Mr. Williamson has had the same difficulty ?.]

The majority of the Mexican individuals and all of those from Arizona have the venation pale brown, both in, 
teneral and pruinose conditions. Yet a few Mexican males, from the same localities, have the venation 
dark, irrespective of whether they are pruinose or not.

De Selys remarks? :—“ Les exemplaires ¢ de Putla (Mexique du Pacifique) sont 
remarquables par leur taille extrémement petite et le ptérostigma plus noir; ceux des 
Etats-Unis un peu plus grands, ont le ptérostigma noiratre, mieux cerclé de blanchatre.
