The i)re.sent paper is intended to give the result of the com- 

 parison of Plates 79 to 107 inclusive, (except figures 1-6 on 

 Plate 82), Adth the collection of the British Museum, and the 

 catalogues of tlie same published from 185-41866. These plates 

 contain the groups usually classed by Entomologists between 

 Sphinx and Xoctua, and are contained in parts 1-7, 31, 32. and 

 35, of the Museum catalogues. The plates according to the foot- 

 notes were edited between the years 1868-1873, while the cover 

 to the Atlas sets forth that they were published collectively in 

 November, 1874. It is not intended to follow the synonymy 

 further than to indicate the identity of the species figured with 

 the specimens existing in the British Museum, leaving for a 

 future catalogue of these families, which I have in prei)aration, 

 the question whether Mr. Walker's determinations have in all 

 places been correct ; as well as the <|uestion of generic distriliu- 

 tion in which the Museum catalogue is notoriously defective. 



Where there can be no doubt of the priority of names, that 

 which should have precedence is indicated in more prominent 

 type than the synonym. 



A prompt notice of this pulilication becomes necessary from 

 the fact that a not inconsiderable number of species have been 

 previously described by the late F. Walker, Esq., from types in 

 the British Museum cabinets. As these were all published 

 before 1866, their names must stand except in cases of erroneous 

 determination. It is greatly to be regretted that there is no 

 letter-press accompanying the Atlas. Indeed, so far as the ])lates 

 alluded to are concerned, there are not even localities attached 

 to the species figured, or any mention of the place of deposit of 

 the types. The latter is an important omission ■vt^hen we remember
