remained mixed in the *' insufflator " till the past summer without apparently losing any 

 of its virtue. Its effect was in nowise diminished. I gave some of the mixture to a 

 friend here whose sheep were infested with ticks, requesting him to try it and report to 

 me. He did so, saying that the ticks seemed to enjoy it and he rolled them about in it 

 without hiconvenience or injury so far as he could see. 



I have both kinds Pyrethrum roseum and P. cinerariifoliuin growing from seed 

 sent me by Prof. Riley. 



There are marked distinctions between the plants from the very first. The seed 

 leaves of P. roseum are spatulate, those of P. cinerariifolium are oval. The former 

 throws out a single leaf from between them j the latter throws out two together. The 

 foliage of the former has a tendency to lie flat on the ground, and looks comparatively 

 feeble that of the latter is ranker and stands much more upright. The plants now 

 (January 1st) look healthy and strong. P. roseum lived out of doors in Ohio through 

 last winter, without the slightest care or protection, in a box above ground. Some of the 

 plants began to grow in February, but a heavy rain^ followed immediately by a hard 

 frost, unfortunately killed their roots late in the spring. Had they been in the ground 

 this accident would hardly have happened. So far as I can see P. cinerariifolium is the 

 more hardy of the two. I will report later on my success, if I have any during the 

 coming season of 1883. 



INSECTS COLLECTED IN 1882. 

 By W. Hague Harrington, Ottawa, Ont. 



SOth March, 188S. 



Although the snow still heavily shrouds the earth, and the air is frosty, the stern, 

 cold sway of winter must soon be ended, and naturalists will again go forth into the 

 fields and forests. Before entering, however, on the coming campaign, I would like to 

 record for my fellow collectors a few facts culled from my copious notes of the past 

 year. The spring of 1882 was very backward, so that insects were unusually scarce dur- 

 ing April and May. On the other hand, the autumn was prolonged and fine, and many 

 species could be collected up to the end of October. On April 25th, I carefully 

 searched the pines for Buprestidse (which at the same date in 1881 were abundant), but 

 could not find a single specimen. On May 11th, a second investigation resulted in the 

 finding of only two specimens of Chalcophora liberta, Germ. On June 6th, this species 

 was abundant, and several specimens of C. virginiensis, Dr., and Chrysohothris Harrisii, 

 Hentz, were also taken. 0. virginiensis, Dr., G. liberta, Germ., and G. fortis, IjGc., were 

 taken again on several days between September 24th and October 16th. On April SOth, 

 Tiger Beetles were making their appearance, and some specimens of G. vulgaris, Say, 

 were taken just emerging from their winter quarters in the sand, under stones and 

 chips. G. sex-guttata, Fab., as is well known, frequents paths and clearings in woods. 

 On wet or dull days it may often be found sheltered under the loose bark of fallen 

 trees, or in the deserted burrows of borers, down which it retreats when disturbed. 

 While stripping the bark from a large prostrate maple on May 22nd, to obtain larvae, 

 I captured three of these beautiful beetles, which had thus been driven to 

 shelter by a shower. The tree yielded numerous specimens of Ewpsalis minuta, Drury, 

 and some pupae of Saperda tridentata, Oliv., from which images emerged on June 15th. 

 On June 16th, while beating the branches of a butternut, I found upon my net a Cur- 

 culio (blackish with an oblique white dash on each elytron), which was new to me, but 

 could find no more upon the tree. As I was leaving the field in which it stood to 

 enter an adjoining wood, I saw upon the gatepost a similar weevil, and a glance around 

 showed me a large butternut growing but a short distance away and having a large dead 

 limb resting on the fence. I at once concluded that the weevils had come from this, 

 and. on examining the decaying limb, hundreds of the beetles were found upon it. On
