September of 1914, although the species has been rare since 

 the great flight of the spring of 1913. 



In the fall of 1913 and again in May and October, 1914, 

 there were abundant examples of the pretty moth Ctenucha 

 venosa, with very black wings, with reddish stripes lengthwise 

 of the fore wings and the edges of the shoulder-lappets also 

 tinged with red. In the spring they were flying about the 

 blossoms of the horsemint, near a wood of hackberry trees. 

 In October they were resting on and flying about the yellow- 

 blossomed broom weed which covers the fields with vast sheets 

 of bloom. In the venosa I also found this strange process in 

 the males. It seems a little stouter in proportion to the size 

 of the insect. In May many of the examples were defective, 

 poorly developed. Normally they are about ^ of an inch 

 long, with the sides a little more crenulated, the crenulations 

 extending around the tube, and dotted with the usual deli- 

 cate hairs. In one case there was a circular fringe of hair at 

 the base, another midway and the usual brush at the end. 

 Sometimes there was a band of golden yellow about the base 

 and one or two more along the tube. The brush at the end 

 was also circular. 



In the fall of 1913 I secured one male of Scepsis fuhncollis 

 which had precisely the same structure, and on October 23, 

 1914, I got two males and one female, and during the next 

 two weeks they were not rare. Always the males possessed 

 this process, never the females, which makes me feel that 

 the first Winchendon example was also a male. In fulvicol- 

 lis the process is much longer and more delicate than in 

 Estigmene acraea and in Ctenncha venosa. It measured in 

 one case i 1-16 inches. The sides of the tubes are hardly 

 crenulated, and the terminal brush very small. In one case 

 there was a thickening at the base, of a slightly different hue, 

 and in this case also a circular brush of hair near the end. 

 On one occasion I cut off the anal segment and extracted the 

 process. Attached to the basal cross-bar was a thread-like 

 tubular structure two inches long, which I thought might be 

 an intestine and probably not a real factor in the case. 



On November 22, 1914, a boy friend brought in a fine
