^4 VARIETIES otf 



altering its name, however, to maritimus. Graslin's original descrip- 

 tion is as follows : " Anticis oleaginis pallidis, aut oleaginis 

 flaveritibus, aut fulvis subcinereis ; duabus fasciis fusco-rubigineis : 

 priori inferne intus product a. Posticis albidis subviridis, aut fulvo- 

 pallidis, nigro variegatis sicut in dipsacea. Acumine palporum nudo 

 nigro " (' Ann. Ent. Soc. France,' 1855, p. 68). To this he adds : 

 " At first sight H. maritima offers great resemblances to dipsacea, but 

 it forms, however, a very distinct species, as may be seen from the 

 description and from its earlier stages. It is very variable in shape 

 and in ground colour ; generally, it is near dipsacea in size, but I have 

 seen specimens larger and some very much smaller " (I.e.). He then de- 

 scribes the form which he considers the type of the species (maritima) 

 as of a " clear olive or greyish-green with two parallel bands of red- 

 brown, sometimes drawing on ferruginous or blackish ; the first of these 

 bands which is larger and darker, distinguishes maritima and dipsacea 

 at first sight. In the latter, the band is wavy interiorly and it 

 finishes by falling almost perpendicularly on the inner margin. In 

 H. maritima it is less wavy and turns in a striking manner away 

 from the body on approaching the inner margin." The second form 

 he describes as " a very remarkable variety which is the most numerous 

 after the type " (just described) having the fore wings of a ferruginous 

 colour, slightly greyish, showing a slight rosy iridescence, with the 

 two bands red-brown. Sometimes these are confluent at their lower 

 parts, where they absorb almost half the wing." Another form is 

 then described with " the ground colour of the fore wings of a pale 

 yellowish-grey tinted with reddish, with the bands, especially the 

 first, brownish-ferruginous in colour and the inferior wings a little 

 paler than the variety figured." " Lastly," he adds, " some examples 

 are intermediate between these varieties, approaching, more or less, 

 one or the other " (I.e. pp. 69-71). These forms appear to comprise 

 all those with a more or less yellowish ground colour. Of Graslin's 

 figures, I noted : " Fig. 1 is yellowish, with a slight green tint, and 

 a dark red-brown central shade (or band) ; the subterminal area 

 red at the costa and inner margin, but greyish in the centre ; the 

 complete basal line is represented by three dots, the orbicular by four 

 dots. A remarkably good figure, but most certainly a form of dipsacea. 

 Fig. 2, like the figures of so many of the older authors, is useless owing 

 to the colour having changed since the figure was drawn and painted " 

 ('Ant. Soc. Ent. France," 1855, PL 7, figs. v. (1-7). I have some 

 British examples identical with fig. 1. 



P. var. luteitinctis, Grote. Grote writes of this : " It appears to 

 represent in North America, the var. maritima, Grasl. of dipsacenx, but 

 differs from that by its larger size, the pale ochreous ground colour of 

 the forewings, which are even brighter yellow than in maritima, and 

 broad black markings on the hind wings. Dipsaceus, in America, has 

 two varieties, interjacens and luteitinctus, neither exactly covered by any 

 European varieties known to me ; the latter is interesting as showing 

 the tendency of the species to vary on both Continents in the colour 

 of the secondaries. Western States (Illinois) " (in. litt. 26. 4. '92). 



y. var. interjacens, Grote. Grote's original description of this is 

 as follows : " This form seems to be intermediate between armiyer 

 and dipsacciis (the American species, which is identical with the latter
