NOTES ON THE BUTTERFLIES OF SURREY AND SUSSEX. 293 



or paler in colour ; the females, however, showed a very wide range of 

 variation from almost entirely blue in varying shades, to deep broAvn 

 without a trace of blue coloration even at the base of the wings. 

 Perhaps the most noteworthy variation was the comparative abundance 

 of the ab. basijuiicta (Tutt), i.e., with the penultimate spot of the 

 submedian series of secondaries united to the penultimate basal spot ^ 

 of this form I have taken six good examples, five females and one male, and 

 at least 20% of the entire female emergence showed a tendency to this 

 form by the two spots in question being slightly drawn to one 

 another. One would in a general way consider this a rather scarce 

 form, as during the time I have assiduously worked this species, I 

 have only found two examples, and in every case this has been 

 combined with ab. inelanotoxa, which is practically the same variation 

 as basijuncta, but on the forewings. Only one example of ab. 

 icarinus was observed, and no example of ab. melanoto.ra simple, 

 although this latter form is usually fairly abundant in the female. 

 The following are descriptions of a few of the more interesting 

 aberrations taken : — 



(1) Female of the bright blue form, with a stripe of male colour 

 running along the costa of left primary from base to outer margin, the 

 costa also is white in places as in the males. 



(2) Female entirely without blue, and with full series of orange 

 liinules, six on primaries and six on secondaries, giving the insect the 

 appearance of A. astrarche. 



(3) Female, of the fuscous form, with blue at base of wings 

 extending to disc, and entirely without orange lunules. A strong 

 glass fails to show any orange scales. 



(4) Two examples of ab. rufiua (Obth.), i.e., with orange rays from 

 the disc to outer margin of primaries, both examples are of a fuscous 

 colour. 



(5) Female underside with orange lunules very much enlarged. 

 To sum up, there has been throughout the emergence perhaps a 



tendency to increase of size of spots, and bold markings on the 

 underside of both sexes. On the uppersides, the males show rather 

 a brilliant tint, although the females range from the brightest blue to 

 brown, the latter form predominates by about 50 of the latter to one of 

 the former. Generally the orange lunules are perhaps more pronounced 

 than usual. I omitted to say that a rather curious fact, was the 

 rapidity with which the emergence ended. By October 2nd it was 

 almost impossible to find a single example in respectable condition, 

 and the species was already becoming scarce. In conclusion one 

 could not find any tendency to dwarfing or malformation. It will 

 perhaps not be out of place to mention that whilst working for 

 P. icarus, I took a female L'oUas edti.sa, in a lucerne field at 

 Caterham on September 26th, and a male at Eeigate on the following 

 day, both apparently freshly emerged. The former I kept for ova, 

 and although kept alive nearly three weeks, I failed to obtain a single 

 ovum. 



(Jelastrina anjiolnii. — This species was first observed on April 24th, 

 and second emergence on July 15th. The larvie from these have been 

 most abundant ; in two or three instances I have found wild larvre 

 eaten by one another. The larva is treated in exactly the same way 

 as an ivy bud — a round hole is eaten into which the larva pushes its
