152 Lord Walsingham's revision of the 



with dark fuscous along the extreme costal margin, with a con- 

 spicuous dark brownish fuscous blotch on the middle of the fold, 

 dilated upwards and blending with the ground colour of the wing 

 its lower edge overlapping the fold, somewhat angulated and more 

 clearly defined ; beyond it is a less conspicuous small patch of the 

 same colour at the end of the cell, followed by a few brownish 

 ochreous scales ; apical vein not forked. Hind wings pale brownish 

 fuscous. Abdomen greyish fuscous ; the anal appendages are of an 

 ordinary form, the lateral claspers being somewhat narrowed 

 towards the base, of even width beyond, the ends rounded ; the 

 uncus is double, evenly curved, somewhat laterally compressed, 

 the points closely approximate and converging. Exp. al. 27 mm.

Chambers describes this species as follows : - 



"Very distinct from plumifronteUa, popeanella, and arcanella, 

 Clem., and from agrotipennella and mortipennella, Grote; nor 

 can I recognise it at all in Scardina or Bombycina, as described by 

 Zeller. Palpi overarching the thorax, dark brown on the outward, 

 luteous-brown on the inner surfaces. Antennae compressed, straw- 

 yellow ; thorax dark grey-brown ; fore wings brown, tinged with 

 greyish yellow ; the usual spot at the end of the disk indistinct ; 

 the other spots common to the wings of the other species I cannot 

 find in this. One of them may be represented by an indistinct 

 blackish line beneath the middle of the fold. Hind wings and 

 abdomen fuscous-grey, like the thorax, and a little darker or rather 

 less yellowish than the fore wings. Under surface of both wings 

 greyish fuscous. Smaller than any specimens that I have seen of 

 the other species, having an alar expansion of only nine lines. 

 Bosque County, Texas." 



To this I may add that the antennas are compressed, flattened, 

 having a roughened or serrated appearance caused by lines of 

 slightly raised scales around each joint. The apical vein of the 

 lure wing is not forked. The lateral claspers are narrow, elongate, 

 slightly upturned from near the base, but straightened beyond, not 

 spoon-shaped, but evenly rounded and slightly inverted at the apex. 

 The uncus is double, straight, the points scarcely at all bent over, 

 \ cry short, not closely approximate, slightly diverging.
