4 BRITISH BUTTERFLIES. 



£. — ? . Left forewing with a somewhat large splash of z colour, running 

 from base parallel to inner margin in two lower interneural spaces, another dash 

 from base to discoidal, then continued more finely nearly to outer margin. Dover, 

 August 1903. Pickett coll. 



o. — s . Brown, but with the left forewing above broadly scaled with bright 

 blue along the costal margin. This specimen further tends to hermaphroditism in 

 having the black points confluent near the lower border of the underside of the 

 forewings. Vernet-les-Bains, July 1895 (Oberthur, Etudes, xx., p. 21). 



ir-p. — Two other ? s show the same peculiarity, but on the right side (1) 

 along the median nervure, (2) near the costal edge. Both from Battershell-Gill 

 coll., the first labelled "Folkestone, 1881 " (Oberthur, Etudes, xx., p. 21). 



s. — 5 . Brown except that the left forewing has a broad band of $ colour 

 extending along the inner margin from base to outer margin (widest at latter). 

 Deal district (Kingsdown), August 1887. Tuttcoll. 



r. — ? . Brown, except that the costal margin of the left forewing is broadly 

 splashed above the discoidal with streaks of g colour, extending almost from base 

 to apex. Sandown, Isle of Wight, August 1881. Tutt coll. 



v. — ? . Left hindwing with a distinct dash of J blue colour from the hind- 

 margin to the centre of the wing. Croydon, July 4th, 1887. Clark coll. 



Teratological examples. — We find in this species some connection 

 between pathological and teratological examples and the wing-mark- 

 ings, especially on the underside. Limiting the pathological aberrations 

 to those that merely show superficial failure of wing-scaling and 

 pigment, and the teratological to those that show modification in 

 morphological structure — wingshape, antenna?, legs, etc. — one often 

 finds that a very slight amount of crippling is accompanied by loss of 

 spotting on the underside, or by change in the normal spotting ; not 

 that pathological or teratological examples may not be normally 

 spotted, but the abnormally spotted — especiall}' in the direction of 

 obsolescence — almost always show some sign of injury, sometimes 

 very slight and difficult to discover, and at others quite obvious. This 

 is so in our own collection, and we have obtained from Pickett details 

 of a very large number of obsoletely-marked examples, to the collecting 

 of which he has paid special attention. To illustrate the connection 

 he has tabulated the specimens as follows : —

The following are the teratological examples that have come under our 

 notice : — 



a. — J . Of normal size, the left forewing with the outer margin drawn in at 

 a sharp angle between the two lower (?) median nervules ; the Cringes developed 

 normally in the depression. The other wings normal. Crissolo, August, 1901. 

 Tuttcoll. 



/3. — e, . Of large size, almost identical with the last, but the point at which 

 the margin is drawn in, nearer the 3rd than the 4th (?) median nervules; a small 

 corresponding kink in the left hindwing, interfering with the double marginal spot 

 near anal angle. Above Preda, August 18th, 1907. Tutt coll. 



y. — S . The left forewing very strongly drawn in (to an angular point), at the 

 extremity of nervure iv. Thoiry, August 12th, 1908. Blachier coll. 



5. — tJ • With slight angular notch In the middle of the outer margin of left 

 forewing. Ste. Maxime, April, 190(5. Chapman coll. 



e. — rf . The corner of the left forewing shortened or cut off sharply at apex, 

 and the outer margin directly below the apex with a concave curve, ending about 

 halfway down the outer margin, and then sloping almost normally to the anal 

 angle. This wing is wider on the outer margin than the right forewing. South 

 Foreland, August, 1887. Tuttcoll.
