appear to be those of a female, (which he has in fact informed me is the case,) differing only from the 
description above given of the male in such characters as are common to the rest of the females in thi 
group of skippers, namely, the want of the discoidal black patch on the fore wings, (in the place of

are only very slightly indicated in the male. The large head, the peculiar pointed inner edging of the marginal 
cules of the fore wings, and the longitudinal, slender, fulvous streak near the anal angle of the hind 
wings seem to indicate the sexual identity of Bucephalus with the male described above * ; moreover, 
Mr. Stephens “could not avoid surmising that the origin of Bucephalus is questionable, and that the 
specimens were probably imported in one of their earlier states among the timber or other stores, which 
Mr. Raddon acquainted him came direct from the North American Continent, to Barnstaple, the section of the 
genus to which this insect belongs being without any other exception exclusively found in America.” We have 
likewise the authority of Mr. Doubleday, whose acquaintance with North American Lepidoptera is superior to 
that of any other living entomologist, for considering the two insects to be thus identical. It should, however, be 
added, that Curtis and Stephens (Append. vol. 4, p. 383) mention that Mr. Newman had also taken a male of 
Bucephalus near Godalming. This specimen has been figured by Mr. Wood in his Index Entomologicus+

This, which is the largest of our British Skippers, sometimes measures nearly an inch and a half in the 
expanse of the wings. The upper wings are tawny brown above, with black veins, the costa, a spot on the 
middle, and an oblique bar beyond the middle, consisting of spots of varied size, emarginate behind, and extending 
nearly to the tip, the two small upper ones being near the margin, whilst three other small spots connected 
together towards the front margin form with the preceding a very irregular, curved fulvous bar. The male 
has the base of the wings brighter orange than in the female, and an oblique central black patch of hairs. The 
hind wings are dark tawny above, (darker in the female,) with an oblong discoidal, and irregular submarginal 
row of paler spots. On the under side the wings are paler tawny, with a greenish tinge, the anterior at the base 
and the anal angle in the posterior brighter fulvous, the former with the base internally black. The pale spots on 
the upper side are here represented of a buff colour, but smaller in size. The antenni are annulated, the club 
dark behind, pale in front; the latter has the tip very sharp, and bent into an acute and sudden angle. 
This common species appears at the end of May, and again at the end of July. It frequents the borders of 
woods, lanes, &c., and occurs in most parts of the country. 

® he distinction between this male and our figures 1 and 2 must not be overlooked, nor the confusion which exists amongst these Skippers, 
owing to the number of closely allied species. It is on this account that I have abstained from speaking more decidedly of the species in 
question.
