 September Ath, 1900. [It would be most interesting if Mr. Lambillion 

 could be induced to collect exact data as to the first appearances, last 

 appearances, breaks in the continuity of appearance, and abundance (or 

 the reverse) of these species, in many localities in different parts o£ 

 Belgium, for a few years. — Ed.] 



During August C'olias edusa has been very abundant in Guernsey, 

 Alderney and Sark, and several specimens of the var. helice have been 

 captured. A few specimens of C. hyale have also been taken, but they 

 have been far less common than C. edusa. — W. A. Luff, Mount 

 Pleasant, Burnt Lane, Guernsey. September 5th, 1900. 



It is certainly a Colias year locally, if not generally. My first 

 sight of a specimen for eight years was at Deal, on August 3rd, when 

 during the only gleam of sunshine I had on a three days' visit I 

 netted two fine C. hyale on the Kingsdown cliffs. The following day 

 I went to Littlehampton, but wet weather continuing until the 12th I 

 did no day collecting. On that day, however, I set out on my bicycle 

 for a Colias hunt, and came across them close to Poling Woods, in a 

 stubble field, with a thick undergrowth. That morning I netted eleven 

 C. hyale and six C. edusa, a proportion between the species which held 

 good in this particular field during the next week. None were seen 

 elsewhere on that day, but during the following week both species 

 occurred sparingly throughout the neighbourhood, and in about equal 

 quantities, but Avhilst in my original stubble field they daily increased 

 in numbers, C. hyale continued to outnumber C. edusa by about two to 

 one. Many male C. edusa were getting worn by the 20th, when I returned 

 home, but nearly every C. hyale was equal to bred. The latter species 

 was not nearly so strong on the wing as C. edusa, and, consequently, 

 much easier to catch, and it also ceased flight for the day much earlier. I 

 rarely saw itmoving after 3.30p.m. or3. 45p.m., when itcould be walked 

 up in some numbers, but C. edusa flew freely for another hour, getting 

 wilder in its flight as the day progressed. Only eleven female C. edusa 

 occurred in all (including one var. helice), six of them on the last day, 

 but C. hyale females were common, including a dozen or more fine, 

 white specimens, and as many intermediate forms. A number of 

 specimens found at rest in the late afternoon in the stubble field were 

 invariably settled down on the stubble, and not on the clover, in which 

 position they were almost perfectly concealed unless searched for very 

 closely, the colour of the undersides exactly harmonising with the 

 straw. On my journey up to town, although fine enough, I could not 

 detect a single specimen on the London side of Arundel, and hearing 

 from a friend this morning that he cannot find either species at 

 Mundesley, on the Norfolk coast, I should judge that the distribution 

 is not nearly so general as in 1892. I have seen no sign of a specimen 

 yet near London. — Eussell E. James, 18, Onslow Gardens, Highgate. 



September 5th, 1900. 



A male Colias hycde was observed on Reigate Heath, August 8th, 1900, 

 the only one seen, although I have not hunted for them. Two males 

 of C. edusa Avere seen between Dorking and Guildford, August 11th, 



1900, and a female on Mickleham Down, August 18th, 1900. This 



$ laid ova, larvas from which are now feeding. On August 19th 

 I found an egg at Reigate, then in the scarlet stage, which hatched 



August 23rd, 1900 ; two imagines, sex unknown, were seen on the
