Segment one cylindrical; two barrel shaped; three to five pedun- 

 culate elongated ovoid; five joined by a moderately broad surface 

 to base of six, which tapers somewhat from its middle to its apical 

 end; seven tapering slightly, blunt at apex. Segments one, two, 

 three, and four pale yellow, five light yellow with a tinge of brown 

 which is more pronounced at apex; six and seven light brown. 



Prothorax about one and one-half times as long as the head ; one- 

 fourth wader than long. Angles not distinct, broadly rounded. 

 Each hind angle bears two slender, light yellowish spines of medium 

 length, and between these pairs along the hind edge of the pronotum 

 stands a row of three smaller spines on each side. Meso thorax one- 

 third wider than prothorax. Wings at the middle about one-twelfth 

 as broad as long; wrings light gray, spines almost colorless, with a 

 very slight tinge of yellow; costal fringe of fore wings composed of 

 rather long bristles intermixed with a row of shorter, slender spines. 

 Costa bears about 22 spines; fore vein bears 9 to 10 spines arranged 

 as follows: A basal group of three or four spines, a gi-oup of three 

 terminating at about two-fifths the length of the wing (these two 

 gi'oups are so close together that they might be considered as a single 

 gi-oup), beyond the second group are three spmes, the first stands 

 beyond the center of the wing, the second at about two-thirds the 

 distance between the first and the third, the latter being near the tip 

 of the vein. Hind vein bears 9 to 11 spines. Spines upon wings 

 quite long and slender. Origin of hind vein indistinct, near the 

 second group of three spines upon the fore vein. Hairs composing 

 hind fringe upon both wings long, slender, w^avy, and light colored. 

 Legs concolorous with body, rather slender; second s^ment of tarsus 

 much longer than the first; spines upon inner side of hind tibia weak, 

 except the almost colorless pair at its inner extremity. 



Abdomen slightly wider than meso thorax, nearly three times as 

 long as wide; posterior edge of ninth abdominal segment bears a 

 circlet of twelve spines, all long and slender except the second spine 

 on each side of the dorso-median line, which is short and indistinct; 

 the dorsum of this segment bears two other spines of medium length, 

 each standing near the middle of the segment cephalad of the third 

 spine in the apical circlet. Tenth segment bears six long slender 

 spines and a number of smaller ones. Tenth segment broad at base, 

 cone shaped and rounded at the tip. Spines upon sides of abdomen 

 short and slender.
