third the length of the segment. Tarsi lighter brown than other seg- 

 ments of the leg and tipped with black wdthin. Hind and middle 

 tibias each bear a long gray spine near the tip without. 



Abdomen twice as broad as the head, almost as broad at the base 

 as at the middle; sixth and seventh segments tapering very slightly, 

 eighth narrowing suddenly; ninth segment only three-fourths as 

 broad as the head. Tube four-fifths as long as the head and at its 

 middle one-third as broad as long. Dorsal posterior margin of first 

 abdominal segment strongly convex, straight only on each lateral 

 fifth. Each dorsal segment two to eight bears a strong, black, blunt 

 spine on the posterior margin near the side. The lateral spines are 

 blunt and short on segments two to five, thence lengthening and 

 strengthening strongly to segment eight. Six strong, dark brown, 

 blunt spines stand in a circlet upon the posterior edge of segment 

 nine, and six long, slender, sharp-pointed spines stand in a circlet 

 on the tip of the tube. The tube also bears about eight shorter, light 

 brown spines intermixed with the longer ones. The wing retaining 

 bristles are strong and black. 



Described from one female taken upon the underside of a leaf of 

 Paulonia im.perialis.
