THE REPORT OF THE 



No. I» 



fastens the portion of the leaf as it rolls it with threads of silk. Jt is bright green, about an 

 inch in length, with a black head and shieltl of the same colour on the back close to the head. 

 The body is spindle-shaped and bears brownish warts. Like other pyralid larva;, it is very 

 active in its movements when disturbed. The moths fiy at Ottawa late in June, and again in 

 August. 



18. Xylina Bethnnei, G. & R. The caterpillars of this noctuid moth were quite plenti- 

 ful near Ottawa, on the 5th June, 1903, attacking the foliage of basswood. They were at that 

 time nearly full grown, ab»ut an inch and a half long, of a pale irreenish olour, with a yellow- 

 ish dorsal sttipe, and had white tubercles. Specimens collected pupated shortly after that 

 date, the moths emerging from the 17th to 26th September. 



19. tnnomos alniaria, Linn. Dr. Packard states that this common larva was found on 

 the linden by Dr. Harris in August and September. Other writers also re^er to the larv;B, as 

 feeding on basswood. 



iO. Catocala cerogama, Gn. On the 31st May, 1901, Dr. Fletcher and the writer found 

 eleven full grown larvfe of this Catocala on a large basswood tree near the Experimental Farm. 

 These caterpillars were over two inches in length, and four of them were greenish, while the 

 remainder were grayish. They all spun their cocoons in about a week's time, and gave us the 

 perfect moths about the middle of July. 



21. An'omeris {Hyperchiria) lo. Fab. Nearly full grown hivvve of this well known 

 species were beaten from basswood by the writer on the 15th August last at Meech lake, near 

 Ottawa. Mr. Winn tells me that these caterpillars were very abundant on St. Helen's Island, 

 near Montreal, during August, 1901. This insect is well known in the mature form, and is 



common "at light" in many parts of eastern Canada. 

 The larvpe, however, are seldom abundant enough to 

 be considered very injurious. They have the habir, 

 particularly when in their earlier stages, of feeding 

 in serried ranks, and on this account attra't atren- 

 tion when noticed. The mature caterpillar (Fig. 14) 

 is a beautiful creature, pa'e gi^een, with tubercles 

 bearing stiff spines of the same colour. Along 

 each side of the body on the abdominal segments 

 is a bright reddish band broadly edged with white be- 

 low. The spines from the tubercles are very sharp and 

 possess strong urticating properties, so are capable of 

 giving a painful sting if the caterpillar is handled at 

 all carelessly. 



22. The Brown-tail moth, Enproctis chriisoiilireay 

 L. This is a European insect which was accidently 

 introduced into the State of Massachusetts some years 

 previous to 1897 — the season its depredations were 

 first brought to public notice. It is thought that the insect was brought to that locality, on 

 imported roses, from Holland or France. Since 1897 the Brown-tail moth has done an 

 enormous amount of injury, its favourite food plant being the pear, but among the many other 

 trees and shrubs which it has attacked, considerable dam.age has been done to the foliage of 

 basswood trees, both Tilia Americana, and T Enropcm. There is only one record of the insect 

 having been taken in Canada, viz. a single specimen of the moth at St. John, N. B. last year 

 by Mr. W. Mcintosh. A valuable account of the introduction into Massachusetts and also of
