Heinrich's 5-volume magnum opus on Ethiopian ichneumonines is commonly cited as 1967-1968 (Henrich (1977) or 1967 (Gauld (1984) and Gupta (1987)). Townes and Townes (1973) cite the volumes as covering the span 1967-1969. Henry Townes' copy of volume V in the American Entomological Institute library has the dates he received his copies written adjacent to the printed dates of issue on page 1258. They are as follows (the printed dates of issue are in brackets):
volume I - December 20, 1967 [April 3, 1967]
volume II - December 20, 1967 [June 28, 1967]
volume III - June 18, 1968 [December 21, 1967]
volume IV - February 18, 1969 [June 20, 1968]
volume V - August 8, 1969 [November 10, 1968]
Henry Townes wrote the following passage below the dates; it is reproduced here in full: "In August, 1969, I asked Hilda Heinrich why the above dates are so much earlier than the dates on which I received copies. Her reply indicates that the above dates are the ones on which the books were printed in Germany. After this, a copy was sent air mail to Gerd Heinrich & the rest came by ship, through customs, and to Farmington State College. She believes that I am among the first subscribers to receive copies. This means that the publication dates are 7-10 days prior to the dates that I received my copies. H. Townes. Aug. 1969."
Given this information, the dates of publication should be regarded as those listed by Townes (and used in Townes & Townes, 1973). Systematists and users of catalogues should take these into account avoiding such mixups as Gupta (1987) in which Paraphyscoteles Henrich is cited as being described in 1968 but with the bibliography giving an unrelated publication for that year.
