272 THE ENTOMOLOGIST' S RECORD. 



mens of this species which are of some interest, in comparison with the 

 P. tear IIS above referred to. Seven of them show either an advance 

 towards ab. salmacis on the upperside, or obsolescence of spotting on 

 the underside. The seven specimens referred to are as follows: — 



One $ has the discoidals clearly ringed with white. 



Two $ 5 have traces of white against the discoidals. 



One (J is similar as regards the discoidal, and in addition has 

 some marginal lunules almost obsolete on the forewing. 



Two 3- 3 lack a few underside spots. 



One 2 has the spots on the hindwings largely obsolescent, and the 

 two lower of the submedian series of the forewings also. The 

 discoidals of the forewings, on the other hand, are greatly 

 enlarged. 



The general characteristics of these specimens may, I thinic, be 

 attributed to the same cause as the variation in P. icams already 

 referred to. 



Ai/riailefi coridon. — During August I collected a large number of 

 this species in its well-known locality in North Herts, and obtained 

 some fine forms. The various modifications of the 5 , including the 

 ab. seniisijni/rapha, Tutt, were in fair numbers. A considerable number 

 of more or less obsolete undersides in both sexes were taken, and one 

 or t\vo nicely-striated. One fine female aberration is entirely of a light 

 " khaki " colour with discoidals white-ringed on forewings and white 

 on hindwings. The most striking feature of the variation was the 

 abundance of the ab. inaequaliH, Tutt, to which so much attention has 

 been directed of late. 



Of the form referred to by Mr. C. P. Pickett {¥lnt. Rec, xxvi., p. 59) 

 and Dr. Cockayne [ibid., p. 221), in which the wings are smaller on 

 one. side than the other, I secured two specimens. In one the right 

 forewing is 1mm. shorter than the left, measured along costa or inner 

 margin, and sprinkled all over, particularly near the inner margin, 

 with blue scales. The hindwings are of equal size and show no blue 

 scaling. In the other both right wings show isolated blue scales, and 

 are |^mm. shorter than the left. In addition the following were secured, 

 all of which, except possibly the last, may be referred to ab. inaeqiialis, 

 Tutt. 



Three specimens with a solitary blue spot above the 5th marginal 

 lunule of hind wing (two left side only, one right side only). 



Eight specimens with more or less pronounced "blue sprinkled " 

 areas on the inner margin of forewings; two left side, six right side. 

 In four of the latter there are also blue-scaled areas in the hindwings, 

 and in one of these the blue reaches the margin, the orange colour 

 bemg absent from the marginal lunule at this point. These specimens 

 are distinct from those next to be referred to in that the blue scales do 

 not form a continuous streak, but are more or less scattered, though 

 arranged in lines following the direction of the nervures. 



Three specimens with " streaks " of blue in right forewing. In 

 each case this streak is between the 1st and 2nd nervures from the 

 inner margin. In one it is only a short hair line near the tornus. In 

 the other two a long streak occupies nearly the whole length of the 

 wing. In one of these the streak is of considerable width. 



One specimen with a similar, irregular " streak " in the left hind- 

 wing, near inner margin, running to hindrnargin. The marginal
