1881.] MR. A. G. BUTLER ON BUTTERFLIES FROM JAPAN. 855 



the submargiiial spots are more dome-shaped, of a bright orange 

 instead of red colour ; and there is a distinct submarginal^white line. 

 Expanse of wings 1 inch 5 lines. 



Shiribetsu, Hokkaido, August. Coll. M. Fenton. 



Leptosia morsei, Fenton. 



Allied to L. amurensis. Wings rounder, not produced at the apex ; 

 the black apical patch lighter : average expanse of L. amurensis, S 

 I inch 1 U lines, $ 2 inches | line ; of L. morsei, S 1 inch 1 1 lines, 

 $ 2 inches. 



Iburi, Hokkaido, end of July. Colls. Fentoii and B.M. 



_ The example sent to us by Mr. Fenton certainly bears out the dis- 

 tinctions laid down in his above description ; and I have little doubt 

 that this is a genuine species. 



Papilio dehaani, var. (?) tutanus, Fenton. 



d . Primaries sharper above than typical P. dehaani; the scattered 

 atoms are slightly brighter and greener ' and are aggregated in a 

 transverse discal bar : below, the broad whitish discal dash of the 

 primaries of P. dehaani much narrower and less distinct, and obso- 

 lete in some specimens ; the scattered ochreous scales of the secon- 

 daries are somewhat paler and are aggregated (densely in some 

 examples) in a curved transverse discal bar ; the violet scales over- 

 arching the red submarginal lunules more numerous. There is the 

 same difference between the sexes ; both sexes vary in a like degree 

 iiiter se. Generally larger. Expanse of wings, c? 4 inches 8 lines to 

 5 inches G lines ; $ 5 inches 6 lines to 5 inches 9 lines. 



Toshima and Iburi, Hokkaido. Colls. Fenton and B.M. 



The summer brood makes its first appearance about the 26th of 

 July, and is on the wing till the middle of September. 



F. tutanus and P. dehaani', near Hakodate, in the south of Hok- 

 kaido, are found feeding together on the same excrement, though I 

 never saw the males of the latter in conflict with those of P. tutanus, 

 or chasing the females, or vice versa. Further north I did not see a 

 single specimen of P. dehaani, and P. tutanus became more abundant. 



The following Lycsenid was unwittingly omitted from my descrip- 

 tions of new species from Nikko. 



Amblypodia turbata, sp, u. 



S . Form and size of A. diardi ; but the secondaries comparatively 

 rather larger, the wings above dark blue instead of violet, and with a 

 rather broad black external border : under surface more like A. 

 apidanus in pattern and coloration, but the costal thirds of all the 

 wings washed with lilac, across which the olive-brown bands rim ; 



1 The colour was noted before the specimens were transferred to the cabinet. 

 The fumes of carbolic acid, present in the drawers, turn them very green. 



- The species sent liome by Mr. Fenton under this name is P. maackii ; and 

 therefore, excej^ting in this description (which characterizes what I believe to be 

 a distinct species much nearer to the true P. dehaani), I have corrected Mr, 

 Feuton's name. — A. G. B.
