hairs, bent over. There is a pair of parallel short honey-yellow lines in the 

 middle of each wing-cover, with a third one a little in front, making in all six 

 streaks. The legs and feet are black. It is a little over eight-tenths of an inch 

 in length." (Packard). 



Bores in elm trees. Mr. George Hunt has observed this species inserting its 

 eggs in the crevices of the bark. Occurs in Ontario and Quebec, but apparently 

 is not abundant. 



5. The Red-headed Clytus, Neodytus erythrocephalus Fab, Order Coleop- 

 tera, Family Cerambycidae. — This pretty little beetle bores in the elm and also in 

 hickory, etc. " It is about one-third of an inch long, and hardly one-tenth of an 

 inch wide, the thorax being very cylindrical and as w^ide as the wing-covers. 

 The colour is a rusty red, the head being of a lighter red, whence the name 

 erythrocephalus, from two Greek words signifying " red-head." The antennae are 

 about one-half as long as the body ; the elytra have four narrow yellow bands 

 across them, and the legs are long and slender, especially the hinder pair, which 

 are almost twice as long as the body. This beetle is exceedingrly quick in its 

 movements, and is difficult to capture as it runs swiftly, and take to flight in- 

 stantly, if disturbed." (Harrington). This species has been taken on hickory by 

 Mr. W. H. Harrington and has been bred from that tree by Drs. Leconte and Horn. 

 It has been found under the bark of an old sugar maple by Mr. G. Hunt, and 

 bred from oak by Dr. Riley. It has been lound boring in dead elms in Michigan 

 by Hubbard, and I have myself found it at Montreal on a fallen red oak. so that 

 it appears to infest various kinds of forest trees. 



At least two species of bark-beetles are known to infest the elm. The 

 Scolytidoe, to which family they belong, are all of very small size. The female 

 drives a long gallery between the bark and the wood, depositing an egg at inter- 

 vals as she progresses ; each larva when hatched drives a tunnel at almost a right 

 angle to the main gallery, and when its transformations are completed, cuts a hole 

 through the bark, through w^hich it escapes. A tree infested by these insects, 

 looks as if it had been riddled with shot, and the surface of the wood is scored in 

 all directions with their burrows, loosening the bark and destroying the tree. 



6. The Elm Bark-borer, Phlceotribus liminaris, Harris, Order Coleoptera, 

 Family Scolytidae. — According to Dr. Harris this little beetle " is of a dark-brown 

 colour ; the thorax is punctured, and the wing-covers are marked w^ith deeply 

 punctured furrows, and beset with short hairs. It does not average one-tenth of 

 an inch in length." 



7. The Black Elm Bark-borer, Hylesinus opaculus, Leconte, Order Coleop- 

 tera, Family Scolytidae. — This is a stoutly built pitchy-black beetle found under 

 the dry bark of elm and ash trees. Both these species are given in the Society's 

 list of Canadian beetles. 



8. According to Packard, The Sxowy Tree Cricket, (Ecanthus niveus, Ser- 

 ville, deposits its eggs in the corky bark of the elm in the Southern States. The 



perfect insect, Fig. 43, is a slightly formed pale green cricket, 

 with ivory white wings ; the 

 female. Fig. 44, with a long ovi- 

 positor. Very common in Ontario 

 and Quebec, as far east as Mon- 

 treal. . I'ig- 44.

 9. The Antiopa Butterfly, Vanessa antiopa, Linne, 

 Order Lepidoptera, Family Nymphalidae. — Every one who has 

 Fig 43. walked through the woods in early spring, must have noticed a 

 large dark-colored butterfly, that dashing up when approached, after circling
