6. The whole of the tenth volume of the “Encyclopédie Méthodique”’ 
was, till recently, supposed to date from 1825. Sherborn and Woodward, 
however, have shown!) that pp. 345--832 were not published till 1828, 
citing the Bibl. franc. for Dec. 13. 1828, p. 886. 
A Through the kindness of Dr. L. O. Howard, I have recently examined 
a copy of this volume in the Department of Agriculture, Washington. It is 
bound in two parts (possibly in the original cloth covers 2), the first con- 
taining pp. 1—344, the second pp. 345—832. The latter also has at the 
beginning a four-page notice (pp. 1—4), entitled “Publication | de la centiéme 
livraison | de l’encyclopedie. | A Paris, chez Mme Ve Agasse, Imprimeur- 
Libraire, | Rue des Poitevins, No. 6. | Le mereredi 10 décembre 1828 | ”’. 
It continues that this livraison contains vol. XII. pt. 2 of Médecine; vol. 
Il. pt. 2 (and last) of the Dictionnaire d’Architecture; vol. X. pt. 2 (and 
last) of the Histoire Naturelle (Insectes). Also the Explanation of the Plates 
of the Insecta, this part complete. The publication-date of part 2. of vol. X. 
may be then definitely settled as Dec. 10. 1828. 
7. Through the kindness of Mr. Prout, I have secured copies of the 
general, and hemipterous, parts of Gistel’s neglected works, and will in- 
corporate the results in the Catalogue. Fortunately, there is very little of 
a hemipterological nature in them. 
8. I have been obliged to cite Berg’s “Hemiptera Argentina” and the 
“Additamenta”’ from (in most cases), the separately paged works. ‘The ori- 
ginal source is the “Anales Soc. Cient. Argent’, and it is possible that 
some of the species dated 1879 are really 1878. It would be of value if 
some one having access to the originals, would publish pagination and dates 
of all the species, as I imagine that most hemipterists are obliged to use 
the separately paged works *). 
I have in preparation a complete ‘Bibliotheca hemipterologica”’, which 
[ hope to publish in a few years; in the mean time, these and the other 
bibliographical references at the heads of the Catalogue - divisions should 
be useful to entomologists commencing the study of this order.
