AND THEIR TRANSFORMATIONS. j .); 



appear to be those of a female, (wliicli ho lias in fact iiifonnoil me is the case,) differiii'^ oulv from tlic 

 description above given of the male in such characters as are common to the rest of the females in this 

 group of skii)i)ers, namel}-, the want of the discoidal black patch on the foro wings, (in the place of 

 which is an oblong dusky spot,) and the more decided and more extended marklnirs on the win^s, which 

 are only very sliglitly indicated in the male. The large head, the peculiar pointed inmr cilgin"- of the marfinal 

 spots of the foro 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 Buceplialus 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 Kurt/i American Conlincnt, to Barnstaple, the section of the 

 genus to which this insect belongs being without any otlier exceptidn exclusively found in America." Wc have 

 likewise the authority of Jlr. Doubleday, whose acquaintance with North American Lei)idoptcra is superior to 

 that of anj' other living entomologist, for considering the two insects to be thus identical. It should, however, be 

 added, that Curtis and Stephens (xVppend. vol. 4, p. .S83) mention that Mr. Newman had also taken a male of 

 Bucephalus near Godalming. This specimen has been figured by Mr. TV'ood in his Index Entomologicusf .

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, cmarginate behind, and extending 

 nearly to the tip, the two small upper ones being near the margin, whilst three otiicr 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 obhquc central black i)atch of hairs. The 

 hind wings are dark tawny above, (darker in the female,) with an oblong discoi.lal, and irregular submarginal 

 row of pakr 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 bufl" colour, but smaller in si/e. The antomte are annulated, the club 

 dark behind, pale in front ; the latter has the tip very sharp, and h.nt into an acute and sudden angle. 



This common species appears at the cud of May, and again at the end of July. It freqf.ents the borders of 

 woods, lanes, &c., and occurs in most parts of the country.
