side and incurved on the distal side (PI. VIII. fig. 2). The movable 

 process (f) is very slightly rounded on both sides, and obliquely 

 truncate at the apex, as shown in the figure. There are four long 

 bristles on this process besides a number of small ones, three long 

 bristles being placed on the apical third, while the fourth is placed 

 half-way between the most ventral one of these and the long bristle 

 of the clasper. The bristles near the apex of the finger are not quite 

 constant in length. The ninth sternite of each side consists, as in 

 the allied species, of a proximal and a distal portion separated from 

 each other by a large sinus. At the proximal corner of this sinus, up 

 to which point the right and left halves of the segment are fused, 

 there are two long bristles, one on each side. A short distance beyond 

 this angle there is a short conical process which projects downwards, 

 and bears a thin bristle at the apex. The distal portion of the ninth 

 sternite is broad with an obtuse apex, the ventral and dorsal edges 

 being slightly rounded with the apex feebly curved upwards (PI. VIII. 

 fig. 3). There are on this portion of the segment three bristles 

 along the ventral edge and five near the dorsal edge. 



? . The eighth tergite has one or two bristles above the stigma, 

 three below it, and four or five ventrally on the lateral surface, there 

 being nine to eleven along the apical edge, of which three or four are 

 longer than the other apical bristles. The stylet is very slender, 

 being four times as long as it is broad at its base. 



We have a series of both sexes of this interesting species 

 taken from Plecotus auritas and ScotopJiilus pipistrellus at Hen- 

 ley-on-Thames, Tring, Wells (Somerset), Harrow, Welwjai, and 

 Tonbridge. 



PAPILIO CAMILLA, Linn^us (1764). 

 By T. H. Briggs, M.A., F.E.S. 



Although it is now thirty-six years since Mr. Kirby, in ' The 

 Zoologist ' for 1872, p. 2952, stated that the Camilla of Linnaeus 

 was the butterfly found in this country, and not the continental 

 species now so named, his statements seem never to have been 

 recognized or adopted since that time, except by Mr. South in 

 his ' The Butterflies of the British Isles,' published in 1906. 



The first mention of " Camilla " was by Linnaeus in his Mus. 

 Ludov. Ulr. No. 122, p. 304 (1764), of which the following is the 

 whole description there given. I must preface this by observing 

 that all the descriptions in this work have a short " definition " 

 at the commencement, and then a detailed description at a much 

 greater length than those in any of the different editions of his 

 ' Systema Naturae' or his ' Fauna Suecica,' and that just pre- 

 viously to this description of " Camilla " is that of prorsa, of 

 which I only need give the short definition at the commencement, 

 as the long one which follows is not material to this paper : —
