Diachus catarms and auratus. Less numerous are Monachus soponatus, Anomcea lati- 

 elavia, Agrilus torpidus ? and .A. fidgens. I am pleased to capture a fine pair of Saperda 

 mutica, as I have only hitherto taken them once. Among other beetles are Trichalophus 

 alternatus, Rhynchites cyaiiellus and Chrysomela muUijmnctata, with larva? of the same. 

 On some trees a sawfly larva, yellow, hairy, with rows of black spots, is very abundant, 

 and there are also larvae of lepidoptera, including one of a Catocala. The raspberry 

 bushes, which a few days ago were alive with bees and wasps, are now almost deserted, 

 but the wilted tips of many of the young shoots show that some enemy has been at work. 

 It is found that a foot or so below the top they have been neatly girdled by two rings 

 about half an inch apart, and that between these rings has been inserted into the 

 pith a long cylindrical egg, that of Oberea bimaculata. From a small balsam 

 poplar is obtained Saperda moesta, and an examination discloses the larvse of different 

 sizes in gall-like swellings, about an inch or two apart, along the shoots which are not 

 half an inch in diameter. Near the root, where the stem is somewhat stouter, is found 

 a much larger borer, which is apparently that of some moth. The hickory grove is now 

 reached, and the first tree yields a fine Saperda discoidea, a very rare beetle here. From 

 other trees the following beetles are obtained : Dorcaschema nigrum, Liopus alpha, 

 Lepturges querci, Leptostylus macula, Hyperplatys asperus, Anthaxia viridicomis, Agrilus 

 egenus, A. otiosus, A. bilineatus and Balaninus rectxis. Several tree-hoppers occur in 

 various stages, including Telamona unicolor and T. Jasciata. There are also some large 

 flat half-grown bugs (yellow, with blackish markings,) one of which has killed a luna 

 caterpillar about an inch long, and is sucking out its juices. The caterpillars of this 

 moth are quite common, but generally smaller than the one mentioned, and a few larvse 

 of other moths are seen. Three specimens of the pretty little butterfly, Thecla calanus, 

 are observed flitting about the trees, or settled upon the foliage. Space will not permit 

 to mention the various galls, etc., which disfigure the leaves more or less. Scattered 

 through the groves are a few oaks, some of which have the foliage noticeably disfigured 

 by large globular woody galls placed upon the mid-rib of the leaf, which is much distorted 

 and curled up. From these galls are just emerging small hymenopterous flies, with ample 

 wings, of which I do not know the name. Some of the leaves are being devoured by 

 brownish caterpillars, half an inch long, with a black head and a pair of black spines 

 projected forward from one of the thoracic segments. They feed side by side in rows of 

 Ave or six and eat the leaf from the tip downward. Upon these trees are found also the 

 beetle B. rectus, which was upon the hickory, and which is remarkable for its extremely 

 long and slender snout. Flying about through the grove are lovely butterflies, Limenitis 

 arthemis, fresh evidently from chrysalis and almost persuading one to be a lepidopterist. 

 Descending now into a meadow, through which flows a sluggish brook, I fold up the 

 beating-net and screw the sweeping-net into its handle, which hitherto has been only used " 

 to tap the branches with. The stream is bordered with clumps of alders, willows, etc., 

 between which grow luxuriantly ferns and many herbaceous plants, with sedges and 

 various grasses. Magnificent fritillaries are hovering about the blossoms of the milkweed, 

 which are just beginning to open, while numbers of Neonympha Boisduvalli flit about 

 ■with a peculiar jerky flight. Beetles do not appear to be as common as they sometimes 

 are here, but I take several specimens of Scirtes orbiculatus, three specimens of fireflies 

 and several allied beetles, with several species belonging to the other families, as Cocci- 

 nellidae, etc. Three or four kinds of sawfly larvse are found but none of the perfect insects 

 are seen. Two, or perhaps three, species of Chrysops are unpleasantly numerous, but are 

 not nearly so aggressive as I find them in a pine wood, through which I return. This 

 wood rings with the shrill music of the cicada and is enlivened by many butterflies in 

 the more open portions, where other trees and plants occur. My captures during the 

 ramble are perhaps fifty species of beetles and a few Hymenoptera. This number is less 

 than half of what I frequently obtain, but the value of collecting depends not so much 

 upon the number of species taken, as upon the observations which are made upon the 

 habits of the various species. 



Swarming of Insects. 



On the 3rd of June last I saw an immense collection of insects between the Chaudiere 

 .Falls and the Canada Pacific Railway bridge across the Ottawa. A long boom-log fixed
