16 BRITISH LEPIDOPTERA. 



forewings have the apex sharper and the costa straighter. They are of a ferruginous- 

 brown, clear, and slightly transparent. The only mark is a cellular point smaller than 

 in any other species of the group ; no trace of lines on either fore- or hindwings, above 

 or below ; the hindwings a little paler than the forewings, of a tint slightly flesh- 

 coloured, but unicolorous. These are also proportionally narrower and the apex 

 noticeably prolonged. The antennae less robust than in P. trifolii (Guen^ei. 

 Localities : France : Burgoyne (Constant coll.). Germany : Carlsruhe, one 

 example in the park (Bischoff teste Reutti). Spain : Andalusia (Lorquin teste 

 Guenee). Switzerland : Zurich (Nageli). 



Chapman notes that specimens from Burgoyne in Constant's coll. 

 are pale red, unicolorous, with only a central white spot, dark-ringed. 

 Hofmann says : " Quite brown, without bands." Staudinger diagnoses 

 the form as : " Alis omnibus brunneis, non fasciatis."

 Staud., " Cat./' 3rd ed., p. 121 (1901). — From Constantine in Algeria I received 

 through Zach a form of trifolii, most specimens of which agree almost entirely with 

 codes from Sicily, but some specimens vary very much ; thus one ? is almost quite light 

 clay-yellow with a narrow brownish transverse line and a white dark-bordered central 

 spot on the forewings. Afterwards I found larvae myself at Constantine, and bred 

 quite similar specimens which are to be referred to var. codes. On the other hand I 

 bred from larvae which were plentiful in May at Lambessa, and were generally to be 

 found on Artemisia, a smaller form, many specimens of which are very near to bathseba. 

 We have distributed these as var. mauritanica which name perhaps might be retained for 

 the Lambessa form. It is true that the specimens vary very much in size, the <? s 33mm. — 

 43mm., the ? s from 45mm. — 60mm. Most specimens are light yellowish and those with 

 brown ground colour are thickly strewn with yellow scales on forewings so that they 

 look more light than dark — in bathseba such a regular thick yellow scattering over the 

 brown never occurs — but it does in many codes from Sicily, so that this var. mauri- 

 tanica is essentially only smaller lighter codes (Staudinger). 



Staudinger later refers (Cat., 3rd ed., p. 121) this aberration to 

 codes, possibly not considering it, on mature reflection, to be sufficiently 

 separate to be definitely differentiated by a distinct varietal name.

 sent a male, dark red-brown in colour, with a pale brown transverse line beyond the 

 middle crossing both fore- and hindwings, the inner margin darker, shading into 

 ground colour, the central spot white, with a dark border, the nervures of all wings 

 paler, no basal line to forewings ; thorax, abdomen and scales at base of inner margin 

 of forewings and at base of hindwings, yellow ; fringes of forewings almost of colour 

 of wings, of the hindwings paler. ? (fig. 334), pinkish-brown with pale yellowish 

 transverse line, paler nervures, white central spot with dark edge, fringes yellowish. 

 Fig. 335 is more oehreous without pink tinge, otherwise of similar form, the area 

 outside transverse line paler than area within and no basal line to forewings. Herrich- 

 Schafler diagnoses it as : " Sordide ochracea (mas obscurior) striga alarum omnium 

 pallidiore pone medium limbo parallela," and adds that Hiibner's figure is good, that 

 generally the insect is of a paler tint, and the form is probably a local variety of trifolii. 

 Localities: Algiers: Bona (Lucas), Oran (Oberthiir). Italy: Central Italy 



(Staudinger), Sicily (C1116). [GREECE (Curd) ]. SPAIN: (Agassi/.). 



Staudinger diagnoses this form as : " Major, al. crassius flavido- 

 irroratis." Lucas notes that the larva of codes bears a great resem- 

 blance to that of /'. trifolii, but from several larvae that he obtained 

 at Bona only one imago ( $ ) emerged. The larvae fed on " sea- 

 Genista" at the end of June, pupated towards the end of July, the 

 imago appearing at the beginning of October. Oberthiir records a $ , 

 taken early in November at Bona. Chapman notes that specimens
