THE CANADIAN ENTOMOLOGIST. 311 



had found boring in various plants, and among them one from the Joe-Pye 

 or Trumpet weed {Eupatorium Purpureuvi, L.). 



When the moth emerged it was seen to be something quite different 

 from anything known to our members. Mr. Brainerd lent it to me to show 

 to Mr. Bird when I visited New York in January, 1904, but that gentle- 

 man did not care to assume the responsibility of describing it before he 

 had an opportunity of seeing the types of G. Nelita, Streck. 



On my trips to Montreal West in July, 1904, search was made for 

 borers in the Eupatoriwn, which grows in great profusion in that locality, 

 and some success achieved, though only a very small percentage of the 

 plants were found to be attacked, which is not surprising considering their 

 extreme abundance, and the attacked plants were difficult to detect, partly 

 because the plant sometimes has a habit of growing with its head bent over, 

 and apparently slightly drooping, and also because it is so very vigorous that 

 it will stand a good deal of boring before showing its effects. About half 

 a dozen, however, were secured, some of which were kindly given me by 

 Mr. Norris. The larvae were not closely examined, as they were supposed 

 to be of only one species, and I was more concerned to secure imagoes to 

 see if they would prove the same as Mr. Brainerd's specimen than to make 

 critical studies on the preparatory stages. These larvae proved rather 

 difficult to rear, as the food-plant tends to dry out even when kept in tin- 

 topped jelly jars, and I succeeded in bringing only three to imago, two of 

 which proved to be identical with the form reared by Mr. Brainerd, except 

 that they are not quite so strongly marked, are a shade lighter in colour, 

 and are smaller, while the third proved to be a small example of G. Cata- 

 phracta, which was not previously known to occur in this locality. On 

 my visit to New York in January last I again took Mr. Brainerd's speci- 

 men with me, and went out to New Brunswick to show it to Dr. J. B. 

 Smith, and to see such of his types in this group as are preserved in the 

 Rutger's College Collection, and as he admitted that he had never seen 

 anything like it, and agreed that Ne/ita, Streck. , was the same as the form 

 I named ALrata^ I had no hesitation in concluding that we have in it an 

 undescribed species, and as Mr. Brainerd did not care to describe it him- 

 self, he has permitted me to incorporate the description in this paper.
