42 THE CANADIAN ENTOMOLOGIST. 



the matter in August last, and, under instructions from the Hon. Charles 

 Drury, the Minister of Agriculture, prompt and vigorous steps were taken 

 by Dr. P. H. Bryce, Secretary of the Provincial Board of Health, to 

 ensure the extermination of so dangerous a visitor, which has been 

 described as " the scourge of the Mediterranean ports." Dr. Bryce's 

 investigations and the methods he adopted have been published in 

 Bulletin I. of the Provincial Board of Health. This pamphlet, which is 

 written in a clear, intelligible manner, and is illustrated with figures* of the 

 insect in its various stages, will certainly be of great use to millers in 

 showing them how to recognize and wage war against the insect should 

 they meet with it upon their premises. Other valuable sources of infor- 

 mation on this subject are Miss E. A. Ormerod's article in her Twelfth 

 Report (pp. 66-72), and Prof. Riley's article in "Insect Life" (Vol. H., 

 pp. 166-171). The object of the present note is to draw the attentionof 

 our readers to the subject, so that the gravity of the case may be recog- 

 nized and prompt advice sent either to our Society or to the Ontario 

 Government in case of further outbreak occurring in other parts of the 

 Province. The perfect moth is a slender species about half an inch in 

 length, with the wings folded close to the body when at rest. The upper 

 wings are of a leaden grey colour, more or less sprinkled with black scales 

 and crossed by three waved dark lines, two near together at the tip and 

 the other a little nearer the shoulder than the middle of the wing. Just 

 beyond the middle and in the centre of the wing is a black dot (some- 

 times two). The under wings are greyish-white, edged by a dark line, and 

 all the wings are conspicuously fringed. The eggs, which are about /„ of 

 an inch in length, are oblong, bluntly rounded at the ends, or some- 

 times rather kidney-shaped. Under the microscope they are pretty 

 objects, being covered with rather large but indistinct star-shaped pro- 

 minences, the rays (or wrinkles) of which are waved. As a rule the eggs 

 are laid singly, but sometimes in strings of from three to fourteen, con- 

 nected at their ends. In nature they are probably laid on the outside of 

 sacks, or are possibly pushed in between the meshes by means of the long 

 ovipositors of the females. One female confined in a glass bottle closed 

 with a plug of cotton batting had forced her eggs into the cotton plug to 

 a depth of over ^ of an inch. When first laid the eggs are greenish-
