well-distributed form, and only differs from the type in being paler. 

 There is, as in all the varieties of tritici, a great deal of minor variation, 

 and subgnthica, Haw. is one of these named forms, differing only from 

 this variety, in having the spaces between the orbicular and reniform 

 and beyond the orbicular, very dark, and in being without the row of 

 cuneiform spots generally present in var. costa-fusca. 



8. var. subgothica, Haw. The diagnosis of Haworth is as follows: 

 " Alis griseo-fuscis, costa late at dimidiatim, stigmatibusque pallidis." 

 " Pra3cedentibus (sagittiferus) affinis absque punctis posticis sagittatis. 

 Stigma anticum subtriangulare, posticum reniforme : ante et inter hsec 

 arcus niger qui reversus apparit in alis expansis. Stigma teliforme 

 prsegrande a basi fere ad medium, sed lineolis duabus divaricatim 

 transversis interruptum. Posticas pallidas fimbria fusca." " Habitat 

 in Anglia valde infrequens " (' Lepidoptera Britannica,' p. 224). The 

 variety is figured in Humphrey and Westwood's ' British Moths,' PI. 

 xxiv., fig. 1, and in the same work we read : " Anterior wings grey- 

 brown, with a broad pale stripe running within the costa nearly half 

 along the wing. The anterior stigma is nearly triangular, and the 

 posterior one is reniform ; the space before, between and behind which, 

 is black, or dark brown. The teliform stigma is very large and ex- 

 tends to the base of the wing, but is interrupted by two pale oblique 

 divaricating stripes ; the centre of the spaces between the veins behind 

 and before the outer stigma, is marked by dusky patches, and the api- 

 cal margin of the wing is very irregularly brown ; the costa itself 

 is marked with numerous blackish dots. The posterior margin of the 

 wing is also marked with a long dusky streak. The hind wings are 

 pale, with a slight central lunule and a dusky border. The abdomen 

 is pale, but rather fulvous towards the tip." A great deal of error 

 has arisen in connection with the synonymy of this sub-variety of 

 Haworth. In America, it has been used as the name of a closely allied 

 species, which is called subgothica, Haw. Unfortunately, Mr. A. G. 

 Butler uses the same synonymy in the ' Trans. Ent. Soc. of London ' 

 '(1889,), p. 377, and in the 'Entomologist's Kecord and Journal of 

 Variation ', vol. i., p. 10, I called his attention to this with other errors. 

 The subgothica of Haworth refers to some British species, for he speaks 

 of it as " Habitat in Anglia valde infrequens " (' Lep. Brit.', p. 224), 

 but the insect known as subgothica, Haw. in America is not British, 

 therefore the American species will have to be called subgothica, Grote 

 (or by some other nomenclator's name), certainly it is not subgothica, 

 Haw. 



F. Ground colour dark greyish-fuscous. 



a. var. sordida, Haw. Haworth's diagnosis of this variety is as 

 follows : " Alis fuscescentibus strigis quatuor submoniliformibus 

 pallidis." "Antennas pectinate. Prascedenti (var. obeliscata) affinis at alas 

 minus rufas, strigis quatuor conspicuis pallidis nigro vel fusco utraque 

 et subundulatim marginatis, et inde moniliformibus ; duabus ante, 

 tertia pone, stigmata. Quarta striga juxta marginem posticum, undata 

 ex punctis confluentibus subflavis. Macula triangularis fusca ante,
