CAMILLO RONDANI AND HIS RELATIONS WITH LOEW 
151 
From a letter to me (Guben, March 5,1869), I translate the fol¬ 
lowing passage, which proves that Loew’s correspondence with 
Parma, at that time, was not very active : “ Guben, March 5, 1869. 
Rondani, with whom I exchange separata from time to time, 
continues his work busily in his w^ell-known manner. Lately, 
he launched his ‘Review of Italian Ortalidae,' and is now occupied 
with the Trypetidae , for which, according to Haliday’s communi¬ 
cation, he seems to have rich material. Polyergus Haliday de¬ 
lights me from time to time by his detailed and often instructive 
letters,” etc. 
When, in 1873, Loew’s monographic paper on Ortalidae appeared, 
(“Monographs,” etc., \ r ol. Ill), I ventured to ask him why, after 
reviewing in this volume the work of all the earlier authors, even 
Rob.-Desvoidy’s, concerning this family, he had not included Ron¬ 
dani among them. Rondani’s papers on Ortalidae had appeared 
in the Bull. Soc. Ent. Ital. two or three years earlier, between 1869 
and 1871. Loew’s answer to me is contained in the following 
passage, which I do not quite understand, and, therefore, do not 
attempt to translate : — 
“ Dass Rondani’s Arbeit iiber die Ortalidae in rneiner Arbeit nicbt beriick- 
sicbtigt ist, bat seinen Grund lediglich darin, dass meine Arbeit lange vor deren 
Erscheinen vollendet war, und auch bei der letzten Redaction derselben sich diese 
noch nicbt in meiuem Besitze befand. Icb babe micb bereits in der 1868 er- 
schienenen Revision der europaiscben Ortalidae auf meine jetzt erst im Druck er- 
scbienene Arbeit und deren systematische Resultate, die da zum Tbeil mitgeteilt 
sind, bezogen, und Rondani beziegt sicb in seiner Arbeit wieder auf die Mittei- 
lungen. So ist es wobl am besten, meine Arbeit bebiilt den Charakter ibres frii- 
beren Abschlusses bei, wie icb ihr denselben gelassen babe.” 
Loew knew that the publication of the first part of Rondani’s 
Ortalidae had taken place in March, 1869. The last part of it ap¬ 
peared in 1871. Loew might have easily obtained this last part if 
lie had been seriously interested in its contents. Why Loew delib¬ 
erately ignored Rondani’s work on Ortalidae , I leave for future 
specialists of this family to unravel. 
In a letter of November 17 (finished November 22), 1872, ad¬ 
dressed to me while I was in Rome, Loew wrote : “ I envy you your 
residence in Italy. If it were possible for me to have about two 
months of freedom from work, I would have used them for an
