42 BBITISH BUTTERFLIES. 



These two forms are not uncommon. Gillmer describes a 2 speci- 

 men of the costajuncta form taken at Nikolsburg in Moravia, July 29th, 

 1904, and we have seen several others in different collections. South 

 mentions (Rut., xx., p. 7) two examples, $ and $ , of basijuheta taken 

 at Folkestone, and figures the $ (op. cit., pi. i., fig. 10).

 ing each other, but not quite uniting into a single band. 



This is a most common form of spotting, the lower basal spots and 

 lower submedian spots of the forewing being extended towards each 

 other, yet not forming a complete arch as in ab. parisiensis, Gerh. It 

 occurs in almost all our British localities, and possibly in most 

 Continental ones. We have it from Bourg d'Oisans, Gresy-sur-Aix. 

 Clelles, Bourg St. Maurice, etc. It is recorded from Giesener Berg, 

 near Hanover (Peets), the Mundelheim Dyke in the Rhine Provinces 

 (Rothke), etc. Bartel notes under the name conflukns (Ent. Zeits. 

 Gub., xviii., p. 115) a $ taken at St. Moritz, July 24th, 1904, which 

 is of the semiarcuate form on the right forewing, but normally spotted 

 on the left.

 (1906). — Both of these aberrations (mariscolore and parisiensis) are already known 

 to be fairly distributed, though possibly the stable, yet minor, aberration 1ms been 

 less noticed, i.e., the one in which the small spots at the base of bhe underside of 

 the forewings coalesce with another of the spots, forming a long ?pot beneath the 

 discoidal. As this aberration is chiefly sent to us from the Parisian entomologists 

 who take it near Fontaineblean, we have named it parisiensis to distinguish it from 

 mariscolore (Gerhard). 



There is always a certain amount of excuse to he offered for the 

 misidentification of not too well hand-coloured ? s of this species ami A. 

 t/ietis, and Blight (sometimes great) differences often occur in various 

 copies of the same hand-coloured work. At any rate, there can he no 

 doubt (judged by bhe copies of Esper in our Nat. Hist. Museum, etc.) 

 that the figure of tiphys, Esp. Die Schmett., i., pi. Ii. (could. i.),fig. 4 . is 

 a,? aberration of ./. thetis, vr'xth underside of the arcuata type as already 

 noted (ant, a, vol. \., pp. 848 and 852-858), referred by Ochsenheimer 

 to coridon (Pic Sr/uiictt., i.. pt. 2, p. 29), the error copied by Kefer- 

 stein (Stett. Ent. Ztg:, 1851, p. 80S), by Staudinger in his Catalog, 

 1st ed., and repeated in the 2nd and 8 rd ed. of the latter work, and then
