genus I liave often found on willow bushes by the railway near Carmel, twelve miles 

 north of Port Hope, and also at several points in the Algonquin Park. It is light 

 yellow-brown with a black margin round each wing-cover and a black stripe down 

 the middle of the same; thighs and abdomen orange-coloured; it is Disonycha 

 caroUniana and a most actjve leaper. There is one more genus of these leapers 

 that 1 have found, said to be uncommon in Ontario; it is a very pretty beetle of 

 fair size, with a close superficial resemblance (in size, shape and colour) to 

 iJ lirysomela lunata; reddish brown all over, this color, on the elytra, being broken 

 into irregular stripes by narrow wavy lines of yellow. I have found it abundant 

 on the north shore of the Upper Eideau, feeding aiways on the Fragrant or Canada 

 Sumach. Blatchley describes it as " common on the sumach/' but I have never 

 found it on the poison-ivy or the stag-horn, only on the Canada sumach, which is 

 a small slirub about the size of a gooseberry bush, having leaves almost identical 

 with those of the poison-ivy, i.e., divided into three leaflets and slightly toothed on 

 one or both margins ; the bark and wood are fragrant, but with a certain pungency, 

 not altogether pleasant. I shall never forget the time and the place that I first 

 found this beetle, BlepJiarida rhois; for I got that day several treasures — this new 

 beetle, a new fern (the ebony spleenwort) the rock selaginella, a new tree (the red 

 cedar) and a new shrub (the Canada Sumach). 



We are now on our way home. First we strike south-west for a couple of 

 miles, through fields and woods : just before we reach the Sowden farm, we pass 

 through some stumps of basswood, round whose base a sheaf of leafy twigs has 

 sprouted. On these leaves I have found' a •smallish wedge-shaped beetle, reddish- 

 brown in color, with some small, darker marks on it; its surface is peculiarly 

 striated lengthwise by alternate furrows and ridges. It is called Odoniota rubra, a 

 leaf miner, feeding between the upper and the under surfaces of leaves and often 

 in the larval stage ^■e■ry abundant on bass wood; it is the only representative of the 

 eleventh tribe known to me. 



At the Sowden farm we turn west on the old York coach road from Toronto 

 to Kingston and pass presently through Dale or Bletcher's Corners. Arrived at 

 the railway track we go south along it to the iron bridge over the Ganaraska at 

 the head of Corbett's pond. Just before we cross you will notice on the steep 

 embankment to our right hand a great growth of wild convolvulus or Morning 

 Glory. It was here that I first found the Coptocycla aurichdlcea, a little tortoise 

 beetle of most marvellous brilliance : it looks, when seen alive on its food-plant, 

 like a dew-drop sparkling in the sunshine and equally iridescent, but this dazzling 

 lustre fades after death to a red gold. It was on the south shore of the lower 

 Rideau that I first met this last tribe of the Chrvsomelidae, the Tortoise-beetles. 

 Feeding together on wild convolvulus, meadow-rue and one or two other plants by 

 the margin of the lake, I found two sorts of beetle, one large and the other small. 

 There were larvae as well as beetles of both kinds on the same plant and often on 

 the same leaf. They proved to be Coptocycla guttata, a less brilliant beetle than 

 anrichalcea, and Chelymorpha argus. I took some larvae and pupse as well as 

 imagoes home with me and watched them mature. These insects have devised a 

 most extraordinary means of protecting themselves. From the end of the larva's 

 abdomen protrudes what naturalists are pleased to call a forked process; on this 

 miniature rack the creature's moults are spread and converted into a sort of 

 tarpaulin by liquid excretions; this is then retroverted and dangles over the 

 creature's back like an umbrella. I wonder if any of you ever came across an old 

 book called the "Voyage and Travpls of Sir John Mandeville"; this mediaeval
