are two further short hairs on a line with tubercle III; this tubercle is situated 

 on the second lateral line and bears one long hair pointing forward and one 

 short hair directed backward; anterior to III on the first tliree abdominal seg- 

 ments are two short hairs. Below the spiracle and slightly posterior to same 

 is a small tubercle with tliree short white hairs (? Illb) and below this on 

 the flange IV + V appears as a large crescentic tubercle with about eight long 

 white hairs. Three short hairs, well below the flange, apparently represent 

 tubercle VI. The thoracic segments show the usual modifications as well as 

 considerable secondary hair on the posterior dorsal portion of each segment."

 Head yellow or ochreous, brown in front and usually above. In some 

 cases the upper part of the head is so nearly evenly colored that the pale patch 

 between the antennae is not defined. Antennae sometimes dotted with brown 

 above. Palpi slender, moderate, oblique ; tips of second and third joints touched 

 with fuscous outside. Legs yellowish, first two pairs striped and shaded with 

 gray-brown on one side. Thora.x yellow. Abdomen yellow with brown dorsal 

 and ventral lines. 



Primaries usually definitely yellow or yellowish, occasionally somewhat 

 ochreous. There is at least a trace of a brown spot contiguous to the base of 

 the cleft, and in a majority of specimens this spot is well marked. The tips 

 of the veins in both lobes are sometimes lightly touched with brown, and there 

 is often a heavy brown shade nmning from the base next to the inner margin 

 into the first lobe. When this shade is absent there is frequently a trace of 

 its outer end in the first lobe. Fringes and secondaries more grayish. Ex- 

 panse 15-21 mm.
