NOTES AND OBSERVATIONS. 35 



being greenish-yellow with very strongly- developed fuscous 

 shadings on the veins. The females on the upperside strongly 

 resemble the example figured in Barrett, plate iii, fig. lc. 

 Two of them have an ochreous ground-colour, in this respect 

 also resembling ab. bryoniae. There is no doubt but that at 

 Inchnadamph the species is single-brooded. At Lochinver on 

 July 17th last I netted a single very fresh example, the only 

 one noticed, a female. This specimen resembles very closely 

 the second-brood south of England form ; it has only slightly 

 dusky shaded bases to the superiors, the usual dark markings 

 are well developed and bright, and the veins on the underside 

 are similar to the southern summer form. There is not any 

 doubt in my mind but that this is an example of a second brood ; 

 it closely resembles Barrett's figure on plate iii, fig. la.

NOTES AND OBSEBVATIONS. 



Colias edusa migeation in Cannes District. — We have had a 

 remarkable visitation of C. edusa to the waste just around our villa, 

 and in to the town (Le Cannet). Almost wherever Inula and cala- 

 rnint were blooming it swarmed, and passed downwards towards the 

 coast from September 10th to October 20th, when with the cessation 

 of the flowering of Inula viscosa they ceased too, having, I feel certain, 

 re-migrated to Algiers or Egypt via Corsica (?). At any rate I am 

 sure they re-migrated, their destination being, of course, a hazard. 

 That these insects had migrated in the first place to Le Cannet I 

 insist upon from the following facts. Firstly, they had all undoubtedly 

 travelled, and showed signs of wear. Secondly, the insects them- 

 selves were larger than the normal local late summer brood (? first 

 autumnal), and appeared to agree with the large form described as being- 

 found in Sicily >{cp. Dr. Verity's remarks, ' Entom.,' vol. liv, p. 187). 

 Thirdlv, thev were almost all females, or at least 80 per cent.— abs. 

 helice and pallida about 30 to 40 per cent., Helicina, a few, a beauti- 

 ful bright (fore wings) cadmium female, with green-yellow hmd wings 

 being to me a new form, border as in ab. acloratrix, Stauder ; others 

 of varying depths. One pallida with damaged right fore wing is the 

 largest edusa I have ever seen. I took about 80 helice, helicina, 

 pallida, and about 60 other orange forms, typical, etc. This series 

 convinces me that it is impossible to say where one form leaves oft 

 and another begins ; that is to say, all the aberrations and varieties 

 merge one into the other in the case of helice, helicina and paUida, 

 for they show all shades. During the latter part of the passing, tor 

 such it was, as the whole ground was worked every day by Mr. lucker 

 and me, and a new batch identified and picked out which for the 

 greater part, were not there the previous day, and together with the .tact 

 that as we worked inland they became scarcer, although the plant did 

 not, seems to indicate that thev worked down to the coast, and as 1 

 think, crossed the sea. The almost entire disappearance with the 

 passing of the flower was also most striking, although at the tune ot
