2? 8 Biufisii lepidOpTera. 



(6) Grey with well-developed lineolae and transverse markings 

 (=:ab. grisea-distincta, n. ab.). (7) With the darker brown shading 

 spread uniformly over all the wings, producing a dark brown 

 unicolorous melanochroic form (=ab. unicolor, n. ab.). The single 

 American example in the Brit. Mus. collection, labelled " United 

 States," is a very typical example of the grey form, with 

 three distinct lineolse and indistinct shades, being very close 

 indeed to Strecker's type figure of saniptri (Lep. Rhop. and Het., 

 pi. xiii., fig. 18), although one of the usual lineolae is very poorly 

 developed in the latter. Butler's var. caligineus, on the other 

 hand, is an exceedingly distinct and well-specialised race of 

 rather small size, of deep grey coloration, often with a slight 

 coppery tinge, tending to uniformity ot appearance, and with 

 the transverse shades developed rather as two faint elbowed 

 lines, one before and one just beyond the middle of the 

 wing ; the central white discoidal spot, apparently rare in European 

 examples, is almost always more or less developed. With regard to 

 albinistic tendencies, Schultz writes (III. Woch. filr Ent., ii., p. 706) 

 that he has a $ with the apex of both forewings albinistic, also a 

 $ with the hindwings partially affected in a similar manner. There 

 is remarkable variation in the coloration of the thorax and abdomen, 

 largely following, however, the tint of the forewings ; in some, 

 especially the eastern examples (var. caligineus), these are practically 

 unicolorous, in others, the thorax is strongly marked longitudinally 

 with dark, and the abdomen takes on a banded form of brown-grey and 

 white almost as marked as bands, as are those of Sphinx ligustri. The 

 only forms that have been described appear to be as follows : 



a. ab. fasciata, Lampa, " Ent. Tids.," vi., p. 26 (1885); Kirby, "Cat.," 

 p. 693 (1892).— Med tvanne morka, tandade tvarstreck i stallet for de tre svarta 

 flackarae pa framvingarne. Se Thedenius, Ent. Tids., 1880, p. 197. — Sverige, 

 Ostergotland [Kindberg] (Lampa) ; Farlof, near Kristianstad (Anderson). 



Lampa gives the name fasciata to that form in which there are 

 two, dark, dentate, transverse lines in place of the three black spots 

 on the forewings. 



/3. ab. asiaticus, Butl., " Proc. Zool. Soc. Lond.," 1875, P- 2o ° ( 1 S75) ; 

 Kirby, "Cat.," p. 693 (1892).— Nearly allied to IT. pinastri, larger, darker, 

 outer margin of primaries straighter, the spot in cell perpendicular, the mediaD 

 streaks longer, the central nebulous fascia less defined ; body dark grey ; pterygodes 

 almost entirely chocolate-brown ; abdomen with lateral black spots smaller, less 

 defined ; wings below paler ; the transverse discal brown streak scarcely visible 

 in primaries, and further from outer margin ; ventral blackish spots larger. 

 Expanse 3m. jlin. " Probably from Scinde " ! [Warwick] (Butler). 



This specimen, now in the Brit. Mus. coll., has the facies of the 

 European and American examples and is very dissimilar from the 

 Japanese form, the only Asiatic one known to us. In fact, it is of 

 exactly the same type as the United States example in the Brit. Mus. 

 coll., i.e., grey, with the three lineoke well-marked and the transverse 

 shades practically obsolete. Hampson states (Ind. Moths, i., p. 123) 

 that, in his opinion, the specimen was not taken in India, and that the 

 "Scinde" label on Butler's type is almost certainly an error.

 (1876); Kirby, "Cat.," p. 693 (1892).— ^. Expands 3ms. Uppersurface in
