80 REPORT OF No. 19 



that a serious tragedy had taken place. The remaining specimen spun a co- 

 coon in a fold of a leaf on Sept. 23. When mature the caterpillar is five- 

 eights of an inch long, body pale green, the black noticeably washed with 

 yellow. Head rounded, green, marked with numerous small reddish-brown 

 dots and large blotch-like spots, the small dots being particularly on upper 

 portion of head. On each side of the body there is a dark brown stripe, 

 broken in places, and touching these two stripes crossing the back is a series 

 of conspicuous wide bands of the same colour. These and the side stripes 

 have a very ladder-like appearance. The spiracles are black and very small, 

 as are also the tubercles. From each of the latter there is a single pale hair. 

 The feet are concolorous with the ventral surface of the body. 



61 of 1903 List. Apatela morula, Grt. On several occasions recently 

 the larva of this noctuid has been beaten from the foliage of basswood at 

 Ottawa. The writer found the caterpillar on July 30 last, and Mr. C. H. 

 Young collected mature specimens on Sept. 2 and 5. Other food plants are 

 elm and apple. When full grown the larva is about two inches in length 

 and is of a light olive grey colour. The head is black, and down the centre 

 of the dorsum there is a wide, uneven, dark gray band, yellowish centrally. 

 On body segments 4, 7 and 11 there is a conspicuous dorsal enlargement, 

 which is bordered on the sides with black. Along the sides of the body are 

 a series of V-shaped blackish marks, with the round black spiracle at the 

 base. The hairs from the tubercles on the body are thin, whitish and rather 

 inconspicuous. In March, 1901, Mr. Young found the cocoon of this moth 

 under the bark of an elm tree, about four feet from the ground, and since 

 that date in confinement, he tells me that two larvae entered soft dead wood 

 to the depth of fully an inch and there pupated. 



OCCURRING ON THE BARK. 

 Order Homoptera. 



121. Eulecanium cerasifex, Fitch. On July 18, I collected some scales 

 on basswood and elm. These were on the lower branches of some old trees 

 growing near the' Arboretum of the Central Experimental Farm. Through 

 the courtesy of Dr. Howard, they were identified as the above species by 

 Mr. Sanders. The scales were fairly abundant on both kinds of trees. In 

 Mrs. Fernald's Catalogue of the Coccidse of tne World, the following food 

 plants are given: — cherry, plum, peach, apple, pear, maple, oak, ash. 



BORING INTO THE WOOD. 

 Order Coleoptera. 



122. The Cherry Flat-headed Borer, Dicerca divaricatu, Say. Speci- 

 mens of this insect were found in basswood on July 9 last by Mr. Frank' 

 Morris, of Port Hope, Ont., on the shore of Eideau Lake, near the Narrows 

 Locks, Ontario. This insect, which is well known as being destructive to 

 cherry and peach trees, is common in Ontario, and always injuriously abun- 

 dant on maple and beech, as also sometime? on pine, birch, hickory and other 

 trees. The mature insect is a brownish, or blackish bronzy beetle, of rather 

 stout build, from three-quarters to almost an inch long. 



84 of 1903 List. Parandra brunnea, Fabr. From the same wood as the 

 specimens of Dicerca divaricata, Say, were taken. Mr. Morris also collected 

 30 specimens of P. brunnea, Fabr. This insect, while it is sometimes found in 

 numbers as occurred at Rideau Lake in July last, is an uncommon species. 

 It is widespread in distribution. The grubs live in the wood of stumps and 

 old trunks of various deciduous and coniferous trees, the beetles being found 

 under the loose bark.
