96 THE CANADIAN ENTOMOLOGIST. 



ENTOMOLOGICAL BOOKS. 

 The following is a copy of the circular recently issued by the 

 Customs Department in order to clear up some uncertainty regarding the 

 interpretation of the circular issued in July of last year. It is now made 

 clear that all books on entomology may be imported free of duty : 



Customs Department, Canada. 



Ottawa, 13th February, 1899. 

 To Collector of Customs : 



The following memorandum was issued on the 28th July, 1898, to 

 customs ports concerned in the importation of entomological books, viz.: 

 "I beg to advise you that the Minister of Customs has determined 

 that books on entomology, such, for example, as ' Insects Injurious to 

 Vegetation,' by Dr. T. W. Harris; 'Guide to the Study of Insects,' by 

 Dr. A. S. Packard; 'Insects Injurious to Fruits,' by Dr. Wm. Saunders; 

 ' Manual for the Study of Insects,' by Prof J. H. Comstock ; ' Economic 

 Entomology,' by Prof. J. B. Smith ; and ' Entomology for Beginners,' 

 by Dr. A. S. Packard, are entitled to free admission under the provisions 

 of item 464 of the Tariff Act." 



You are instructed that free importation of books of the above class 

 is not confined to the special works herein described by name, but that 

 entomological works may be classed as industrial books entitled to free 

 entry under tariff item No. 464. 



(Signed) John McDougald, 



Commissioner of Customs. 



THE ODOUR OF COCCID/E. 

 Apropos of Professor Webster's note, on page 4 of the current 

 volume of the Canadian Entomologist, concerning the odour of 

 Aspidiotus perniciosus, and Mr. Cockerell's note on page 36 on the 

 odour of Toumeyella, please allow me to remind these gentlemen and 

 your other readers that I recorded a similar instance in the case of 

 Gossyparia ulmi in Insect Life, Volume II., page 39 (August, 18S9), on 

 the authority of Mr. J. G. Jack. The wording is as follows : "At this 

 time they secrete a great deal of honey-dew which attracts ants and other 

 insects, and gives off, curiously enough, a pungent odour, which Mr. Jack 

 states is noticeable where large numbers of the coccids are at work, but 

 which we have not noticed at Washington, probably on account of the 

 comparative scarcity of the lice."
