Body tawny : head and chest beset with some long black bris- 

 tles, of which there is a row on each side of the crown, there is also 

 a cross-fringe of short black bristles behind the eyes ; epistoma very 

 slightly prominent ; sides of the face without bristles : eyes red ; 

 fore part flat, its facets much larger than those elsewhere : sucker 

 pitchy, clothed with tawny hairs ; palpi tawny, beset with black 

 bristles: feelers tawny, as long as the face; third joint conical, 

 rounded at the tip, nearly thrice the length of the second ; bristle 

 black, downy, slender, tawny at the base, much more than twice the 

 length of the third joint: chest and abdomen clothed with short 

 bright tawny hairs : abdomen oval and shorter than the chest, with 

 the exception of the tube ; the latter is nearly cylindrical, about as 

 long as the preceding part, and tapers slightly to the tip, which is 

 black : legs tawny, clothed with short tawny hairs ; claws black ; 

 fore thighs armed beneath with black bristles : wings colourless, 

 adorned with tawny marks, which form a fork from the base of the 

 wing ; the upper branch is a regular stripe along the fore border for 

 one half of the length, and includes a ferruginous brand near 

 its tip ; the lower branch is much curved and joins the tip of the 

 upper, and thence proceeds to the fore border, which it accom- 

 panies to the tip of the wing, leaving a triangular colourless space 

 between ; parallel to it, and a short distance beneath is another an- 

 gular band ; these tawny marks are clouded with brown, and there 

 are two dark brown dots near the base of the second longitudinal 

 vein ; wing-ribs and veins tawny ; longitudinal veins slightly wav- 

 ing, the third curved upward at the tip ; lower cross-vein separated 

 by a little less than its length from the middle cross-vein, and hav- 

 ing two very indistinct curves, the upper outward, the lower inward ; 

 middle cross-vein straight, slightly oblique. Length of the body 

 5i lines ; of the wings 10 lines.
