252 LETTERS TO MR. LOUNSBURY [CHAP. xxi. 



But I have not robust health, so that I can sympathise. 

 With renewed thanks for the welcome contents of yours 

 lately received. 



March 12, 1894. 



I am greatly obliged to you for your kind present of your 

 " Beitrage zur Kenntniss der Phyllocoptiden," with its first- 

 rate descriptions and magnificent figures. It is a very great 

 advantage to me to be in possession of your noble work on 

 these creatures, and I feel myself very much indebted for 

 all the great help you have given me. 



About the Phytoptus ribis. I delayed replying because I 

 thought that if any thoroughly complete description of this 

 Phytoptus had been published by Professor Westwood it 

 would be sure to be known of by Mr. W. Hatchett Jackson, 

 of Keble College, Oxford, who was Professor Westwood's 

 chief assistant. But he tells me that " under the generic 

 name of Acarellus I can find nothing but a brief paragraph 

 without figure in the accounts of the meetings of the Entom. 

 Soc." Mr. Jackson adds, " I remember the occasion very 

 well, and making slides for him from specimens in our own 

 garden. I shall search for those slides in the Hope 

 Museum." W. H. J. 



After some search here I found the enclosed, and as I 

 think you would desire to see the fullest account which I 

 believe Professor Westwood published, I have detached the 

 page. If he were still with us I know how he would have 

 delighted in your splendid unravelling of what was then a 

 mystery. At your best convenience, when you have quite 

 certainly no further use for the page, perhaps you would 

 kindly let me have it back. 



In my own early observations of the habits of the Currant 

 Phytoptus I noted it as P. ribis, Westwood, on the authority, 

 or rather after the example, of Mr. Andrew Murray (see 

 " Aptera," p. 355), for we had not in those days any more 

 trustworthy and accepted guidance, but as to comparing 

 these with such a work as yours, no one with the least atom 

 of knowledge would think for a minute of such a thing. 

 Yours very truly, 



ELEANOR A. ORMEROD. 



To C. P. Lounsbury, Esq., Government Entomologist, 

 Cape Town.

 DEAR MR. LOUNSBURY, It gave me great pleasure to
