Moth. — Two $ . Light mouse-brown; palpi above blackish; sides of the tuft on the vertex of 

 the head grayish; prothorax with a faint dark line. Middle of the fore wings grayish, dusted 

 coarsely with browu. Differs from I>. anyuina in having a zigzag or scalloped cross line on the 

 basal third of the wing within which the wing is tawny brown, not white, as in anguina; also a 

 double scalloped line ending just within the inner angle. Costa toward the apex interrupted by 

 gray spots, which are more distinct on the underside. A submarginal row of very oblique darlv 

 linear spots between the venules, succeeded l)y lighter, longer streaks of light tawny white. 

 Fringe gray, with dark spots. Pectinations of the antenuie a little longer than in D. anguina. 

 Tarsi tipped with lighter scales. Hind wings inousebrowii. 



Expanse of wings, i , o(i mm.; length of body, i , 1(J mm. 



This species differs decidedly from I>. angtiiiia in having a zigzag cross line on the basal third 

 of the fore wing within which the wing is tawny brown, not white: also a double scalloi)ed line 

 ending just within the inner angle. Besides, there are no black lines, and the body is mouse- 

 brown in hue. 



Dr. Dyar has kindly lent me a colored sketch of Walker's type of H. thgatiroides in the 

 Oxford Museum, received from Colonel Swinhoe. There seems to be little doubt but that it is my 

 D. interna.
