A NOTE ON DUTCH CHKYSOPHANUS DISPAB, Haw. 

 By N. D. Eiley, F.E.S. 



I HAVE recently had an opportunity of examining 3 cJ aud 4 2 

 specimens of the so-called Dutch CJtri/sopJianus dispar, Haw., at 

 one time thought to be identical with our extinct English race, 

 and have found them most interesting. Although they cannot 

 1)6 called true dispar, they make the nearest approach to dispar 

 I have seen in any Continental race. 



In size and general coloration there is, to my mind, nothing 

 to distinguish them from dispar. There are, however, the 

 following small constant differences : 



(1) In both sexes the marginal red band on hind wing under- 

 side is consistently narrower than in dispar; it is also con- 

 sistently broader than in other continental races I have 

 examined. 



(2) The black spots on the underside, especially of hind wing, 

 are consistently smaller than in disjMr, and on the whole larger 

 than is the rule on the Continent. 



(3) In the <? the black marks in all and at cell-end on the 

 upper side of fore wing are consistently smaller than in dispar ; 

 also on the whole larger than is the average of Continental 

 specimens. 



(4) The hind margins of fore wings below in both sexes are 

 invariably greyer than in dispar, in which they are usually 

 brownish. 



(5) The tendency in the ? for the black spots in the band on. 

 the upperside of the fore wing to be produced towards the base 

 of the wing in long rays is apparently very pronounced in Dutch 

 specimens — much more so than in dispar or in any Continental 

 race I know of. 



(6) The ground-colour of fore wings below in both sexes is 

 slightly paler than in dispar, but not so pale as in ordinary 

 Continental forms. 



From the above it will be seen that the Dutch race is clearly 

 intermediate between dispar and rutilus, and to my mind is 

 equally distinct from both these forms. It is only natural to- 

 expect to find in the Dutch specimens the race most nearly allied 

 to our extinct race and most pleasing to find that this is actually 

 the case.
