standing and possessed remarkable talents as an artist. She is well known as the 

 authoress of the magnificent series of thirty colored diagrams of insects injurious to farm 

 crops. These are thirty inches long by twenty wide, and are most suitable for use in a 

 class room or at farmers' institute meetings. In the preface of the report the sad event 

 referred to above is touchingly and fittingly alluded to with a reference to the obituary 

 notice by Dr. Bethune which appeared in the Canadian Entomologist for November last. 



Among the various short monographs contained in this report of 160 pages many aie 

 of interest to Canadian farmers and fruit-growers either from the identical species occur- 

 ring both in England and Canada, or from a similarity in habits between allied forms in 

 the two countries. 



Codling Moth : This is one of the yearly recurring troubles of the fruit grower to 

 which most of the damage to apples may be laid. English experimenters do not even yet 

 seern to have mastered the spraying of apple trees for the prevention of injury by the 

 codling moth. The remedies are given by Miss Ormerod as follows : " Our only really 

 available remedies against this infestation appear to lie 1st in destroying infested apples ; 

 2nd in trapping the caterpillars and destroying their shelters ; and 3rd on being well on 

 the alert at the time of the blossoming of the apple, and by careful spraying preventing the 

 very beginning of the attack." In this country the recommendation for the best remedy 

 would be : " Spray with 1 lb. Paris green and 1 lb. lime in 200 gallons of water within 

 a week after all the blossoms have fallen." 



Beet Carrion Beetle : We have occasionally in the North- West Territories a 

 rather rare attack upon vegetables such as squashes, spinach, etc., by the larva? of one of 

 the carrion beetles Silpha bituberosa. In England a very similar species has been the 

 cause of serious damage to mangolds, and last season when other food failed attaoked 

 potatoes. The carrion beetles feed both on vegetable and decaying animal food. It- 

 is suggested by a correspondent to attract the beetles and larvae from the crop by putting 

 about the infested fields '* a few wild pigeons, rooks, hawks or similar vermin." (Sic.) 

 The ignorant farmer in England, as well as in other parts of the world, " generally shoots 

 in spring " every hawk he can see. In this country the remedy which would first sug- 

 gest itself would be dusting the crop with land plaster and Paris green (50 lbs. to 1). 



Leather Beetle : An interesting account is given of an attack by Derme&tes vul- 

 pinus. Large numbers of beetles were found in a building where bones had been stored 

 for six or nine months for the manufacture of manure, and not only the bones were 

 honeycombed, but also the posts and floors of the building over them, which were 

 seriously injured by the larvae, when full-grown, boring into the wood to pupate. 

 Reference is also given to another similar occurrence near Sheerness, in Kent, which 

 was upon even a larger scale than the one treated of by Miss Ormerod. This article 

 is illustrated by excellent figures of the beetle and its various stages, as well as a 

 portion of a perforated bone and a piece of honeycombed wood. 



White Cabbage Butterflies: Under the head of cabbage two species of Fieris 

 are treated, and powdery dressings are recommended as fresh lime, soot and sulphur. 

 The highly reprehensible practice of using Paris green upon cabbages is referred to, but 

 Miss Ormerod wisely says she could not take on herself the responsibility of advising the 

 treatment, more especially as the feeling against 'it might probably ruin the sale of the 

 cabbage. There is no doubt of the truth of this last statement. There is never a season 

 passes that instances do not come under the notice of the writer of people expressing fear 

 of buying cabbages lest they may have been poisoned with Paris green. In addition 

 to this the use of such a virulent poison is quite unnecessary. Pyrethrum powder mixed 

 with three or four times its weight of common flour and kept for twenty-four hours 

 in a tightly closed vessel is even more quickly fatal than Paris green, killing every 

 caterpillar the powder falls upon, or upon which the infusion of the powder may run 

 when it has been wetted by Jew or rain, and further, this powder is not poisonous to 

 the higher animals. 



Croton Bug : An occurrence of this well-known guest at hotels and other large 

 buildings heated with steam, is spoken of. The usual remedies adopted in this country
