of linden in June. Other trees upon wliich the beetles feed are birch, bitter 

 hickory, elm, beech, oak, etc. The beetle is about one-third of an inch long, 

 cylindrical, the body of a dark colour with the wing covers testaceous and 

 more or less tinged with green. Beneath, the body is densely clothed with 

 short white hairs, and is sparsely hairy above. The legs are long and slender, 

 the hind ones being blackish. 



Order Lepidoytera. 



97. Gluphisia septentrionalis, "Walker. This is a common species at 

 Ottawa, the larvae usually occurring on the aspen, Popuhis tremuloides . A 

 single caterpillar of this notodontian, three-quarters of an inch in length, 

 was found feeding on basswood at Ottawa on the 10th August. When ma- 

 ture the larva measures one and a quarter inches in length, and in general 

 appearance is smooth, cylindrical, pale green, with a distinct yellow subdorsal 

 band, and a series of bright red dorsal blotches on all the body segments ex- 

 cepting the abdominal 1st, 2nd and 10th. The head is darker than the body 

 and has on each side a conspicuous black stripe. 



98. Heterocampa bilineata, Pack. The larvse of this species were fair- 

 ly common at Meech Lake, Que., in 1901. Most of the specimens collected 

 had been feeding about five feet from the ground, on the foliage of new 

 shoots. Mature larvse found by Mr, C. H. Young about the end of August 

 produced moths the middle of the following June. Other food plants of the 

 larvae of this species are elm and beech. Notes on the larval stages may be 

 found in Packard's "Bombycine Moths of America North of Mexico." 



39 of 1903 list. Coleophora tilicpfoUella, Clem. One case of the larva 

 of this tineid moth was found attached to a basswood leaf on the 21st June, 

 1904, the moth emerging on the 30th June. The imago was identified by 

 Mr. W. D. Kearfott, who has sent a description of the moth for publication 

 in the Canadfan Entomologist* This is the first record that we know of, of 

 the species having been found in Ontario. 



99. EUida caniplaga, Walk. In Holland's Moth Book linden is men- 

 tioned as the food of the caterpillar of this notodontian. The moths have 

 been taken infrequently at Ottawa, the dates of their capture being 13, 

 16, IT May, 5, 8 June, and 6 July. We have never collected the larva. 



'Order Diptera. 



68 of 1903 list. The Basswood Wart Gall, Cecidomyia verrucicola, 

 O. S. This gall was very common on basswood leaves the past summer 

 at Ottawa. It occurs irregularly in 'numbers on the same leaf, in numer- 

 ous cases more than a hundred galls being found on the same leaf. 



Order A carina. 



69 of 1903 list. The 'Linden Gall-mite, Phyt^optus ahnormis, Gar- 

 man. On the 27 July some leaves of basswood were received from Mr. 

 Z. A. Lash, Four Way Lodge, Lake Rosseau, Ont., which showed the work 

 of this mite.
