The first object of the Author’s ambition has been to win the approval, by his Works 
of contemporary entomologists. He has, therefore, peculiar pleasure in quoting the 
following unsolicited opinions : — 
“ M. Hewitson, aussi habile dessinateur que savant lepidopterologue, porte un nom 
qui restera dans la science. Grand amateur et possesseur d’une des plus riches collections 
da monde en papillons diurnes, il a debute dans la carriere entomologique comme collabo- 
rates d’Edward Doubleday (Diurnal Lepidoptera, 2 volumes in folio). II en a lui-meme 
execute toutes les figures. Ce talent si apprecie de M. Hewitson ne devait pas s’arreter la. 
En 1856 il a entrepris, sous le titre de ‘ Exotic Butterflies,’ la publication in quarto d’un 
splendide ouvrage dont trois volumes sont completement termines et le quatrieme en bonne 
voie. Ce magnifique travail, qui forme un supplement indispensable aux illustrations de 
Cramer, de Drury, de Hubner et a toutes les iconographies modernes, ne sera jamais surpasse 
sous le rapport de l’exactitude rigoureuse du dessin et de la veritd de coloris.” — Boisduval, 
Lepidopteres de la Californie. 
“ Der dritte Band von W. Hewitson’s * Exotic Butterflies ’ bringt abermals einen 
grossen Beichthum an neuen und ausgezeichneten Arten, deren zahl sich auf 1 99 belauft, in 
abbildungen, welche bis jetzt an Eleganz und Naturtreue unubertroffen dastehen, zur 
Kenntniss. Die Tafeln gewahren in Anordnung und Colorit einen gleich angenehmen 
Eindruck ; sie sind weder uberfullt noch unharmonisch und lassen in beider Beziehung 
einen kiinstlerischen Geschmack erkennen.” — Gerstaecker, Bericht. 
“ Mr. Hewitson’s beautiful illustrations of Butterflies have regularly appeared 
throughout the last two years, and fully maintain their high reputation for delicacy of 
execution and superb colouring. Long may he live to continue them ! till they form a 
monument of his patient skill and enthusiastic love of nature, unequalled by the work of 
a single individual in any age or country.” — A. B. Wallace, President of the Ento- 
mological Society of London, 1871.
