Vol. XXvi] ENTOMOLOGICAL IKWS. 169 



September of 19 14, although the spedet has been rare since 

 the great flight of the spring of 191 3. 



In the fall of 191 3 and again in May and October, 1914. 

 there were abundant exaiiq>les 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 tpring they were flying about the 

 blossoms of the horsemint. near a wood of hadcberry treca. 

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

 blossomed broom weed which oorers the fields with vast ibeets 

 of bloom. In the vtnosa 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 aboot H of an indi 

 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 fuhncoiiu 

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

 191 4, I got two nudes and one female, and during the next 

 two weeks they were not rare. Always the males p oss es s ed 

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

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

 lis the process is much longer and more delicate than in 

 Estigmunt acrara and in Ctenucha vmosa. 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
