is a fine ■<-slia])e(l black mariiing on tlie furcation of the nervure. In some speci- 

 mens tliere is also a faint blackish line at the end of the median nervure of the 



lower wings. Abdomen yellow, the base and apex infuscated. 



Expanse of wings, 4 mm. 



Larva. — Pale greenish-white, slightly convex, elongate-oval, almost smooth, but 

 the segmentation of tlie abdomen evident, also there a median row of coneolorous 

 round spots ; there are also two series of six distant, subdorsal, stout, prominent 

 hairs of various lengths, at different spaces from each other, and two hairs at the 

 anal apex ; all these being unicolorous with the dermis are not easy to see, except in 

 profile, but can be well distinguished by varying the focal distance in the microscope. 

 This agrees with Signoret's diagnosis. The margin very narrow. The eye-spots 

 brown, large, conspicuous. Length, 1 mm. 



Pupa (not described by Signoret). — When mature, deep golden-yellow, very 

 glossy, true oval, convex, the dorsal area with fine transverse ridges, irregular on the 

 thoracic region ; the ordinary anal triangular formation small, short, entire ; the 

 margin wide, flat, with regulai", raised, transverse striae ; the usual circumferential 

 white waxen fringe wide. The dorsal hairs of the larva have mostly disappeared, 

 but a few of them are persistent in some specimens. Length, 1 mm. 



Koch (Aphiden, 327, 4, fig. 396) describes a species which he calls 

 A. Jonicerce, but Prauenfeld says that, as it has wings entirely white, 

 wdthout any marking, it is not the lonicercd of Walker. Signoret, 

 however, cites Koch's species as synonymous with Walker's, observing 

 that it represents a specimen newly developed from the pupa ; but 

 there being many species with wings entirely white, I think this 

 assumption is very doubtful. 



Walker's description is as follows : — 

 " On Lonicera periclymenum. Yellow. Head and thorax grey. The fore- 

 wings white, with a dark spot on each. Pupa white, pale yellow beneath and on 

 the disc above. England." 



This is very meagre and insufficient. As to the colour of the 

 pupa I infer that it refers to a newly changed example, or even to a 

 larva adult. On the whole my description is not discrepant, allowing 

 for the dense mealy covering of the imago. 

 Signoret says of the imago : — 

 "Yellow (jaune). I have always seen on the oldest examples only one spot on 

 the (white) elytra at the end of the median nervure in the same manner as the spots 

 on the abdomen, a large spot on the prothorax and on the metathorax, the base of 

 the abdomen broadly blackish." 



This is not exactly the same as in my description, but the 

 difference may, I think, be attributed either to another way of stating 

 the case, or to a variation in individual specimens at various ages, such 

 as is known to exist in other species.
