HESPERIA MALV^E. 225 



be kept separate. A form very closely allied to melotis, Dup., 

 is quite common in all the warmer parts of southern France — 

 Hyeres, Draguignan, Cannes, Digne, etc., whilst the hypoleucos of Syria 

 is a very different-looking insect in its extreme forms. Running 

 through the specimens in our own collection we notice : (1) A long 

 series from Saeterstoen, in Norway, June-July, 1898 — the $ s small, 

 grey-haired, with abundant, but rather small, white spots, tending to join 

 transversely ; two 2 s only, somewhat darker, but spotted almost like 

 the $ s, not quite so much white, however. These examples 

 belong no doubt to the typical Linnean form, with abundant spotting 

 exteriorly, without, however, these outer marginal spots developing into 

 ab. zagrabiensis, Grund. . The undersides fuscous-olive, with well- 

 developed white spots ; both sexes the same. (2) A long series 

 from Digne, April, 1897 — rather larger than, but otherwise more like, 

 the Saeterstoen specimens than those from Draguignan, Hyeres, 

 etc. They are well spotted ; the 2 s are darker, and with rather 

 smaller spots. The undersides of the forewings greyish, of the hind- 

 wings, olive-fuscous or brown-grey, a considerable difference existing 

 between the extreme grey and extreme brown forms; the white markings 

 rather mottled. These are very close to the Linnean type in general 

 appearance and spotting. Afew 2 s from Digne are large, black, with well- 

 developed markings, not quite so black in the ground colour, or with such 

 contrasting black spots, as in the real melotis, Dup. ; we call this ab. (et var.) 

 australis. (3) Three 2 s from Draguignan (May, 1905) — dark, well- 

 marked 2 s of ab. australis form. (4) From Hyeres, one 2 , March, 

 1903, one $ and three 2 s, April, 1905 — rather large, the $ less in wing- 

 expanse than the 2 s; dark, with well-developed spots; much larger and 

 darker than those from Saeterstoen ; remarkably good examples of the 

 southern form, ab. australis ; underside hindwings, $ rich red-brown ; 2 s 

 olivaceous-brown ; the white markings distinct, somewhat silvery. (5) A 

 long series from Cannes, March and April, 1897, 1899, 1900, 1903 — <? s 

 smaller than 2 s ; of the same form as the last, the J s well-marked, 

 but the 2 s with clear white markings very strongly developed on the 

 forewings, also well-developed on the hindwings, particularly the upper 

 part of the central band. Underside of hindwings grey, olivaceous- 

 grey, and deep olive-brown, well-marked with white. (6) Aix-les- 

 Bains, May, 1897 — a well-marked 2 -, not unlike some of the Digne 

 examples. (7) Locarno, April, 1899, 1903, and May, 1902 — both 

 sexes especially black ; the white markings of the forewings, particu- 

 larly contrasting and reminding one somewhat of those of carthami ; the 

 hindwings dark with very white spots, in some only a few spots, in others 

 a well-developed transverse band ; the undersides olivaceous- brown y 

 in some quite brown, well-marked with white. Undoubtedly the var. 

 melotis, Dup. (8) Vernet-les-Bains, July 26th- August 11th, 1905 — 

 Two eastern Pyrenean examples from Oberthur of good size, the <? 

 slightly larger than the 2 , and powdered slightly with grey at base ; 

 both specimens of dark ground colour, white spotting clear ; both sexes 

 with outer marginal row on forewings obsolete, on hindwings also, in 2 

 rather less so than in $ ; in both sexes only the white discoidal spot of 

 hindwings conspicuously marked. The underside of the hindwings of $ 

 brown, of 2 deep brown (inclining to chocolate) ; white spots not parti- 

 cularly clear in tint = yar. pyrenaica, n. var. (9) Canales de la Sierra, two* 

 $ s, one 2 • Intensely black like the var. melotis, spots equally white, but,
