1802. Fauna Boica, 1, 2, 157. 
Hyes naked, fringed at the margins with rather short hairy lashes, 
_ quite variably distinct and sometimes feeble. Tongue long and strong. 
_ Head large, not prominent, somewhat retracted. Front smooth, ves- 
titure even, woolly. Palpi moderate, scarcely exceeding the front in 
_ the males, usually reaching the middle of front in the females. Anten- 
ne simple in both sexes, except in serraticornis, in which the joints 
are laterally produced and bristled in the male. Thorax stout, quad- 
rate, collar greatly developed, in perfect specimens forming a sharp 
keel and projecting hood-like over the head. Vestiture consisting of 
‘long, flattened hair. Patagie distinct. A variable, never prominent, 
posterior tuft. Legs moderate, stout, well clothed with hair and seales, 
not spinose. Abdomen long, conic, much exceeding secondaries, with 
a series of dorsal tufts very prominent and distinct in convexipennis, 
moderate only in all our other species. These tufts are easily dis- 
lodged, and specimens otherwise perfect may be deficient here. Pri- 
“Inaries comparatively small, narrow, with acute apices, lanceolate or 
nearly so. Secondaries proportionate to primaries, small as compared 
_ with the body; a slight excavation in the outer margin opposite the cell. 
The species are comparatively few in number, and I am inclined to . 
believe that most of them are known. The high western plateaus and 
the Pacific coast may yet yield a few additional species, but not many, 
Ithink. They are closely allied and yet not difficult to separate when 
_¢are is taken, because there is little variation, and small characters 
_ prove constant in large series. 
The narrow, lanceolate primaries, hood-like collar, and long abdomen, 
combined with the lashed eyes and unarmed legs, make the genus an 
easily distinguished one. 
The species, except convexipennis, are very similar in color, all of some 
shade of ashen gray, sometimes with a brown suffusion. In all, the
