7092 Insects, 



at the beginning of May, in the blossoms of the yellow dog-tooth 

 violet or adder's tongue {Erythronium Americanum) and on the cat- 

 kins of willows. I have presented specimens of them to the British 

 Museum. 



Cmlioxys. An unnamed species is common at Montreal and St. 

 Hilaire in August. It appears to me to come near C. vectis, Curtis. 



Stelis '- ? A species bred from wild rose twigs bored by 



Osmia. 



Family Dasygaste^. 



Osmia similUma, Smith. Taken on the River Rouge, in the town- 

 ship of Arundel, county of Argenteuil. It much resembles O. Latreillii, 

 Spin. 



O. ? A small species is common at Montreal in July, and 



I obtained it from bored wild-rose twigs, which I collected round 

 Montreal in the winter of 1856 — 7. 



Meyachile acuta, Smith. Very numerous at Montreal, and I took 

 it on the river Rouge, in the township of Arundel. In July nearly 

 every leaf of the rose-bushes in gardens has a circular piece or two 

 cut out from it, but I never saw this bee actually operating on one, 

 though I have captured a female when in the act of cutting a piece 

 out of the leaf of a seedHng maple. I once found some old nests of a 

 species of Megachile ? composed of the petals of buttercups {Ranun- 

 culus) in the crevices of stones in a loose wall. As M. acuta is very 

 like M. Willoughbiella, it is not improbably the species referred to 

 under the latter name by Mr. Gosse, in his ' Canadian Naturalist.' 



M. melanopJicea, Smith. Occurs abundantly about Montreal at the 

 same time as the last species. 



Ceratina dupla. Say. Abundant in July on blossoms of Solidago 

 about Montreal. In February, 1857, I collected numerous shoots of 

 a bramble which had been bored by these bees, and I found six or 

 seven specimens inside them, lying head downwards in a torpid state, 

 having apparently entered them to hybernate, and so late as the 19th 

 of May following I found numerous specimens in bramble-shoots, but 

 they were then active when disturbed. In some, below the perfect 

 insects, were brownish larvae and cocoons. Many of the shoots, several 

 feet in length, were bored down to the very root. In one I found a 

 bright green larva, like that of a sawfly, which appeared to have been 

 feeding on the pith, and I also met with the nests of a minute Crabro ? 

 {Rhopalum, Kirby) filled with Aphides.
