216 BRITISH BUTTERFLIES. 



very properly be regarded as representing nose-spines. There are also 

 some slight median wrinkles ; also a rough point (obsolete hair ?) 

 in the centre of the eye. The labrum is a very small triangular 

 piece, about l-8mm. long, the mandibles meet in the middle line for a 

 similar distance. The 1st legs, are broad, but short, reach 2-3mm. 

 down maxillae, followed by the 2nd for about 0-8mm. The antennae run 

 to the end of the wings, side by side, for about 2-2mm., after meeting over 

 the proboscis. On both sides of one specimen (others not examined) 

 the tibio-tarsal articulation is marked both in the 1st and 2nd legs by 

 an unusual structure, viz., a group of circles, that are possibly entitled 

 to be called lenticles. On one side, the 1st leg has seven of them, 

 and the 2nd five; on the other the 1st has five and the 2nd 

 three. Another specimen is slightly different in numbers. A faint 

 trace of these exists in Paimicia pJdaeas (not in Chrysophanus dispar), but 

 it is distinctly present in all the Theclids I have examined. That it is 

 absent elsewhere is a statement for which I cannot claim ready accept- 

 ance, as they are very large and well marked in the pupa of Callophrys 

 rubi, yet up till now have escaped my notice. In C. rubi the 

 network of sculpture, which is elsewhere on the legs rather vague 

 and irregular, is distinct and very like that on the body where most 

 marked, as above the spiracle of the 3rd abdominal segment; notably it 

 has the stellate points from which the ribs radiate, and, amongst these, 

 but dissociated from them, are one or more large lenticles. In one 

 specimen the forelegs have nine points and one lenticle on one side, 

 six points and one lenticle on the other ; the 2nd legs have 

 respectively five and seven points, but each has three large lenticles. 

 In another specimen the number of points and lenticles are different. 

 [I have been accustomed to regard the appendages as free from the 

 special coverings, hairs, etc., of the body surface ; a hair or two on a 

 wing margin being exceptions I have regarded as teratological. Here, 

 however, is, at the tibio-tarsal articulation, a genuine bit of body 

 sculpture and armature. Does it occur largely throughout Lycaenids ? 

 and elsewhere ? It seems to be absent in Hamearis lueina.] The 

 prothorax (returning to S. pruni) is variously wrinkled, with 

 stellate points at the intersections, in a few places anteriorly nnd 

 posteriorly, whilst, at the dorsum, lenticles are numerous, as are also 

 minute hairs (about O'OSmm. long), pale, tapering, and spiculated. 

 The mesothorax is wrinkled ; there are a good many stellate points, 

 showing the wrinkling to be essentially the same as the netting on 

 other Theclid pupaa ; lenticles are much less numerous than on the 

 prothorax ; there are also very many, but fewer, hairs of just the 

 same character; they are here more obviously curved. The same 

 description would apply to the metathorax, but items of sculpture are 

 fewer and less marked. The short, sharp, pointed wing portion is dark 

 and wrinkled, but (being wing) without hairs, points, or lenticles. 

 The 1st abdominal is much the same. The following abdominal 

 segments have abundant lenticles round the spiracles. The wrinkling 

 tends to the netted form with stellate points, most distinctly a little 

 way below and behind the spiracles. Lenticles are sparse dorsally, 

 e.g., on one side of the 5th abdominal are eleven lenticles above the 

 spiracular group, which has something like 70 of them. Hairs are toler- 

 ably regularly distributed, of almost the same character and length as 

 elsewhere; on one side of the 5th abdominal above the spiracle there are
