they had been made by the inch and then cut into ten, fifteen or more pieces. They 
live under the bark of various trees, and //ylastes pinifex and others were taken at 
King’s Mountain. On the occasion of our trip to meet the Montreal Natural 
History Society at Calumet, the season was more favourable to an abundance of 
insect life, and many species were observed, including some of our largest 
butterflies. Unfortunately, the only member who collected butterflies on this 
excursion (Mr. Greata) has since left the city, so that I do not know exactly 
what ones were taken. Among them, however, was Danais archippus, which is 
a very large butterfly with tawny orange wings, margined and veined with black, 
and bordered with a double row of white spots. The caterpillar, when full 
grown, is about two inches long, and is banded with alternate transverse stripes 
of yellow, black and white. It has also a pair of thread-like black horns at each 
énd, and may be found feeding in June and July upon the common milk-weed. 
Another large and handsome butterfly seen was Papilio turnus, the yellow swal- 
low-tail, the caterpillar of which feeds upon apple, wild cherry, ete., and is of a 
light green color, with rows of blue spots along the back, and a curious eye-spot. 
yellow with a black centre, om each side of the third segment. Lhe caterpillars 
of this and cf Papilio asterias—the black swallow-tail—when touched, thrust out 
through a slit just behind the head, a curious forked scent-organ, which emits a 
<disagreable smell, apparently with the object of driving away insect foes. Colias 
philodice, the bright yellow butterfly, was abundant. Its larva feeds upon clover, 
which valuable plant, by the way, is known to be relished by over fifty species of 
insects, <A fine species of tiger-beetle, Cicindela longalabris, which I have never 
observed elsewhere, was taken, apparently searching for ants, in the open spot in 
which we all Junched. ‘liger-beetles have received their name from their 
swiftness and fierceness in seizing the insects upon which they live. The larve 
live in sandy or light soils, in perpendicular holes, at the top of which they lie in 
wait for passing insects. Three species of these beetles are common, viz. : 
Vulgaris, the common, J//irticollis, the hairy-necked, and Sex-guttata, the six- 
spotted. The two first are to be found upon roads, or sandy places; they fly 
swiftly a short distance when alarmed, and also run quickly about. Cicindelu 
ser-gutlata is more frequently found sunning itself on fences and stones. It is 
of a lustrous green, with six, or frequently eight yellow spots on the wing-covers. 
Another fine tiger-beetle, C. purpurea, is found in fields among the grass, and is 
more difficult to capture. A beetle taken at Calumet in some numbers was 
Saperda vestita, the clothed or coated saperda, so named from its covering of short. 
yellowish hair. Its length is about three-fourths of an inch,and the larva,figured with 
the beetle, in centre of upper row, does much damage sometimes to lindens. An 
allied species, Saperda tridentata, the “ three-toothed Saperda,” was also taken ; its 
larva is an elm-tree borer. A third species Saperda candida, a brownish beetle with 
two longitudinal white stripes, is also found around here, and is knownas the apple- 
tree borer, on account of its damages to that tree. Two more long-horned timber 
beetles were taken on young basswood trees, viz.: Clytus ruricola, a black beetle 
with yellow markings, and Clytus erythrocephalus, a delicate and rare beetle, of a 
hrownish colour, with three yellow bands. The five beetles just named awe among 
the fifty species of Cerambycide which IJ have painted, and are as nearly as possible 
correct in size, markings and coloring. All these fifty were taken in this immediate 
vicinity, and, in addition, I have some twenty others. Owing to the extent and 
diversity of the surrounding woods, Ottawa is very favourably situated for the 
collection and study of wood-eating insects, of which there are many belonging 
to different orders. Two species of Buprestians were also taken at Calumet, viz, : 
Dicerca divaricata and Grachys terminuns. The iarva of the first bores in beech 
and cherry, etc.: that of the secend mines in the leaves of the basswood ; that 
is, it lives between the upper and lower surfaces of the leaf, and devours the soft 
tissues. The white blotches so frequently seen in different kinds of leaves are 
thus formed by mining larvae. The Buprestians are remarkable for tke solidity,
