430 BRITISH LEPIDOTERA. 



existing between the larvae of the " early " and " late " forms of A. 

 Irifolii, the latter of which seems to have been the form Speyer 

 obtained (although he speaks of certain imagines he bred as belonging 

 to the small-winged form), so that he evidently knew and obtained 

 both forms. Three very fine examples sent to us by Oberthiir, 

 and captured by Lahaye, at Geryville, Algeria, May 10th-20th, 1886, 

 are of the bronzy-green form in both sexes, the fore-wings rather 

 narrow and the hind-wings with a very broad hind margin. They 

 are much more like some of the ab. orobi, that Christy obtains at 

 Emsworth, that Battley has sent us from Broxbourne, and Parry 

 from Wye, than any other trifolii we have seen. Oberthiir notes 

 syracmia as very common at Lambessa, and adds that it does not 

 vary. He states that this is the only Anthrocerid that, in his knowledge, 

 is found both in Algeria and Europe. All other Algerian species, he says, 

 appear to be confined to Africa, and are not to be found on the opposite 

 coast of the Mediterranean. 



. var. seriziati, Oberthiir, " Etudes d'Ent.," i., p. 33 (1876) ; iii., p. 41, pi. v., 

 fig. 7 (1878) ; xiii., p. 21, pi. viii., figs. 71-73 (1890).-Eesembles much certain 

 varieties of A. trifolii, spoken of by Rambur (Cat. Sys. And., p. 177, pi. i., figs. 5-8), 

 but probably a distinct species. In any case, it is a most striking race, and should 

 be designated by a name. Compared with A. trifolii it is a little larger; it has 

 similar spots on the upper wings, which vary in size, but do not tend to be con- 

 'fluent. The lower wings are more rounded than in A. trifolii. Sometimes they 

 are red, broadly bordered with blue, more often the red is invaded by the blue, 

 but always leaves two red spots, one round in outline, towards the outer angle, the 

 other elongated, rather indefinite, and having its origin at the base of the wing. 

 The special character of A. seriziati is its tendency to have the inferior wings 

 invaded with blue. It is very common at Collo (Oberthiir). 



This insect has certain close connections with A. stocdiadis (caucasia, 

 Bdv.) ; it should not, however, be confused with the latter, (1) because 

 the green areas are blue in seriziati, (2) all the vinous-red portions of 

 the wings in stoechadis are of a scarlet-vermilion tint in the Algerian 

 species. These differences are constant, and as a result the two insects 

 have a different aspect. It has many very striking characters which 

 distinguish it at once from trifolii-syracusia, trifolii-palustris and 

 trifolii from southern France. It appears to inhabit the littoral 

 region of Algeria from Bona to Collo ; the var. syracusia, on the con- 

 trary, is found among the low mountains of the interior, at Lambessa, 

 Geryville, etc. The two insects have not yet been found together 

 (Oberthiir). Judging from a couple of specimens M. Oberthiir has kindly 

 sent to us, we can only say that the insect is a most striking form, 

 and that, in spite of its brightly-coloured blue fore-wings and the 

 very broad marginal border of the hind-wings, it has a most marked 

 trifolii-palustris aspect. 



o. var. gracilis, Fuchs, " Stett. Ent. Zeit.," xli., p. 118 (1880). Smaller and 

 slighter than A. trifolii. The fore- wings, from base to tip, 13 mm.; dark blue- 

 green, with five crimson spots, the third spot small and always separated from the 

 fourth. Hind-wings red ; the border narrower, the black colour rather produced in 

 the centre and at the apex. Abdomen black. The antennte long, extending 

 farther than the fifth spot, with a thin knob ending in a small tapering point. 



Fuchs notes that his specimens (3 $ s) were captured in July in a dry 

 sunny meadow near Bornich, and were at first taken for ab. orobi, but he 

 considered that although they might belong to a local form of A. trifolii, 

 their characters necessitated comparison with A. mcliloti trndA-lonicentc ; 

 thus yracilis is a little larger than the former, it has similar markings, and 

 narrow border to the hind-wings, but diifers in the shape of the wings,
