SCALY WINGED COPEOGNATHA. 107 
The Amphientomum Hageni, Packard, proved to be a true Kch- 
mepteryx from the figure of the fore wing and from the description. 
I had already pointed out in 1902 (/.c. p. 15) that it did not belong to 
the genus Amphientomum. <A comparison of this description with 
that of #. agilis, Aaron, showed that both descriptions characterise 
extraordinarily similar forms ; only Packard’s figure of the scales 
did not agree with Aaron’s. The former however are of such a high 
development (at the end with 5-6 acute teeth) as has not yet been 
demonstrated in any of the Copeognatha (even in the differentiated 
forms only bidentate scales occur) more especially in such a lowly 
organised genus, in which and in whose allies dentate scales never 
occur, mostly indeed only asymmetrical scales, that I consider it 
very probable that Packard, who has investigated every possible 
order of insects, accidentally admitted some Lepidopterous scales 
into the preparation which naturally did not surprise him among 
the slender scales of Echmepteryx (cf. fig. 107); moreover the 
Lepidopterous scales may have attached themselves to the Ech- 
mepteryx in the killing bottle. I have myself often received Psoci- 
dz which were quite covered with adhering Lepidopterous scales. 
In addition there is the fact that both Packard and Aaron captured 
the objects in the north-western part of the United States and that 
in both cases they were found living on tree trunks. 
I believe therefore that I am right in uniting the two species, 
especially because Aaron was unaware of Packard’s description. 
In Aaron’s drawing, the distal portion of the subcosta which closes 
the pterostigma in the fore wing, and7, in the hind wing, are want- 
ing ; doubtless Aaron overlooked both. 
As I was about to send off this manuscript, I received, through 
the kindness of Mr. Banks, some examples from the United States 
(Falls Church, Virginia, June) alleged to be Amphientomum Hageni, 
Pack. An examination of this material completely confirmed the 
view which I have explained above. The scales are exactly like 
those figured by Aaron. 
Echmepteryx mihira,* n. sp. (Figs. 22, 81, 106, 122). 
Head clear brownish yellow. Hair of forehead and vertex rather 
long, shaggy, brownish yellow. Antennz thin and long, about 
equal to length of fore wing; antennary joints short, ntmerous ; 
in one antenna there are 39 joints of flagellum (consequently 41 
antennary joints) present, but it is imperfect ; each joint with some
