THK ENTOMOLOfilST S HKOORD. 



A. rori'lon, female. Wings on left smaller with some blue scales 

 on upperside and nearly obsolete on underside. Wings on right larger, 

 quite brown above, and with larger spots on underside. Leeds, 

 Royston, 1915. 



Pob/ow Hiatus iranis, Rett., ah. bifoniiift, Tutt. The upper surface of 

 the right side a beautiful blue iranis colour, bearing a row of marginal 

 black spots, inwardly edged with red on both fore- and hindwings. 

 The left side of ordinary female colour with orange marginal band well 

 developed. The ground colour of the right underside a lighter brownish 

 grey than is usual in a female, that of the left side a more typical 

 brownish grey. Captured at Hochsfcedt, near Hanau, 1904. It was 

 described originally as a gynandromorph. Tutt considers it to be a 

 female, but gives no reason for this. No description states that the 

 wings are equal in size, or that the blue is distributed as in a blue 

 female, and most important of all no mention is made of the absence 

 of androconia. {Soc. Eat., Zurich, 1905, xx., p. lo2 ; Ent, Zcitscln; 

 Guben, 1906, xx., p. 157; Tutt, Jhit. Butt., vol. i., p. 148.) 



Flebeius argus, L. {agon, Schifi".), ab. daple.i', Cockerell. The wings 

 on the right side brown, those on the left strongly shaded with blue. 

 Both sides equal in size. According to Tutt this was not a gynandro- 

 morph, but a female showing a different form of female colouring on 

 each side. Again no mention is made of androconia' or of the distri- 

 bution of the blue scales. It was taken in the New Forest, where 

 intersexes are found. (Bond, Ent. Month. Mag., 1872-1873, ix., p. 200 ; 

 Entniiiologist, 1889, xxii., p. 6 ; Tutt, Brit. Lepidopt., vol. x., p. 188.) 



Flebeiiis argus. This year I took a specimen which can be referred 

 to ab. duple.r. On the right side the wings are brown except for a very 

 few blue scales at the extreme base. On the left side the forewing has 

 a splash of blue at the base, and scattered blue scales running out to 

 the marginal area, the hindwing is heavily marked with blue, which 

 extends to the outer lunules. The blue scales are serrated like those 

 of a female, and no androconia are present. The wings are equal in 

 size, and the underside and abdomen are female. [Trans. Ent. Soc. 

 Loud., 1922, pit. vii., fig. 2.) 



Agrtades coridon, Poda, female. The right side is lightly sprinkled 

 with blue scales at the base, extending out beyond the disc on the fore- 

 wing and hindwing. The right hindwing has tiny blue wedges inter- 

 nal to the lunules. The left side is heavily sprinkled with blue, ex- 

 tending out beyond the discal area in the forewing. The left hindwing 

 is so blue that it approaches ab. scmisgngrapha, and has large blue 

 wedges internal to the first lunules, but posterior to nervure 3 it is all 

 blue. No androconia or coarse hair-scales are present. The wings are 

 equal in size, the underside, ab. parisieiisis, Gerh., on both sides, and 

 the abdomen, are female. L. W. Newman, Royston, 1920. I am told 

 that two other similar specimens were taken in the same locality in 

 1921. 



Agriades coridon. Three examples were captured at Royston in 

 1920, females with the wings on one side brown, and on the other 

 resembling ab. sgugrapha. Refers., but of a deeper blue. I think these 

 are really extreme forms of ab. inaequalis, Tutt, and are probably a 

 form of intersex, although they do not possess androconia. It is un- 

 likely that they are somatic mosaics, half tj^pe, half ab. sijngraiiha, 

 because only one completely blue female has been recorded from Roys-
