_Le Dessus._--Les antennes sont noires. La tête le corcelet et l'abdomen bruns. Les aîles (dont les bords sont unis ou point dentélés) sont d'une couleur brune foncée, avec une nuance couleur d'argille se levant proche des bords antérieurs des aîles supérieures, qui court le long près des bouts et finit aux bords extérieurs. _Le Dessous._--Les yeux sont noires, les antennules jaunes. Toutes les aîles sont de la même couleur brune que en dessus, avec la nuance d'argille proche des bouts chacune des aîles supérieures a cinq taches blanchâtres, placées sur une ligne près des bords extérieurs. Les inférieures ont chacune quelquefois cinq et quelquefois sept taches de la même couleur rangées circulairment et se rencontrant près de l'extrémité du corps. Il l'ai reçue de la Chine. Je ne le trouve point décrit. The name of Papilio Eumeus was consequently proposed for this insect in the Appendix to the second volume. Amongst the manuscripts with which I have been favoured by the relatives of Mr. Drury, or have obtained elsewhere, are comprised a variety of notes relative to the publication of this work, and of observations from which the following are selected. He notices that "his _descriptions_ are only intended to assist the reader in ascertaining the different species; and that they are not intended to be so complete as to give a perfect idea of the animal without the help of the figure." He alludes to the difficulty not only "of ascertaining true colours or calling them by their proper names," but also of "colouring the prints so, as to exactly represent the natural specimens,"--that he has mentioned and given English names to no more parts of insects than had suited his purpose for describing them,--that "there are some parts mentioned in the descriptions which cannot be seen in the plates, such as the Gorget (Sternum), &c. which may serve not only to assist in classing them, but to ascertain their species." "The descriptions of the Hymenoptera are not intended to be so complete as to give a perfect idea of the insect, but are only given to assist the reader in observing the figures." "All the descriptions are taken from the insects themselves; whatever defects, therefore, are to be observed in comparing them with the coloured figures must be imputed to the artist, as it would not be proper to describe them according to the prints, but to {vii}nature."--It is in consequence of this last remark that I have been careful to omit nothing of the original edition in this edition of the least importance, but have given the description as much as possible in the words of the author himself. I have also added a general Systematic Index to the entire work, and an Alphabetic Index, in which the names employed in the first edition are distinguished by an asterisk.
