68 THE ENTOMOLOGIST. 



entire or almost so (fig. 1). The spots forming the submarginal 

 series are often linear or cuneiform, but rarely round ; in some 

 specimens the submarginal spots unite with those of the marginal 

 series, forming internervular streaks (figs. 3 <? and 4 ? ). Some- 

 times the area between the base of the wing and the sub-basal 

 band is blackish (fig. 2 J"). 



i'ig. 6. Fig. 7. 



Comparing the series of E. crihrum under consideration with 

 continental representatives of the species, I find that the English 

 specimens differ from all foreign examples that I have seen in 

 the matter of the longitudinal streaks. None of the continental 

 specimens in the National Collection at South Kensington, or in 

 Mr. Leech's collection, have these streaks; there is no mention 

 of these characters in the original description, neither does 

 Esper's figure exhibit them. On the other hand, in not one of 

 the one hundred and seventy odd specimens in Mr. Eowler's 

 series are the streaks absent. There is nothing in the variation 

 of the English specimens tending in the direction of var. Candida, 

 Cyr., beyond the form represented by fig. 5, but the continental 

 named form has white lore wings, and is devoid of marking 

 except two black dots at the outer extremity of the discoidal cell. 

 Some of the sufi'used specimens from Eingwood approach var. 

 rippertii, Boisd., but cannot be correctly referred to that form. 



The streaks referred to are certainly not typical of E. 

 crihrum, it might therefore be well that the forms in which 

 they are present should have a varietal name, and I would 

 propose hivittata as being a suitable one. All the other characters 

 are so exceedingly variable that it would seem to be useless to 

 suggest names for the numerous modifications.

Note. — The antennae in figs. 1, 2, and 3 have not been correctly 

 drawn ; this was, unfortunately, only noticed when too late for 

 alteration.
