ANTHROCERA ACHILLE.E, ESPER, IN SCOTLAND. 223 



general gfoiips : (a) Piirpuraliformes, (/>) Transalpiniformes, and 

 (c) Carnioliciformes. Without going into the scientific value 

 of the system adopted, it may be remarked that A. achillecs, 

 outside colour and size forms, has been rather less liberally 

 treated by modern authors in the matter of varieties and forms 

 than most of the commoner species of the group. One trembles 

 to think what Fruhstorfer — that progenitor of legion " sub- 

 species " — would do with the Anthrocerids were he let loose 

 among them. 



Dziurzjaiski supplements the several forms admitted to 

 varietal rank or described as aberrations by Staudinger, with the 

 following, using the word "forma " throughout : 



(\) fulva, Spuler.— Reddish-yellow ; yellow spots sprinkled 

 wiih red scales. 



(ii) hraniua, Dz. (figured). — The typical red coffee-brown.* 



(iii) hlackieri, Dz. — Chiefly a ? ab., spot 3 wanting, the other 

 spots very small. 



(iv) cingnlata, Dz — Abdomen red-ringed. 



(v) confluens, Dz. — Spots 1 and 3, and 2 and 4 confluent ; 5 

 isolated. 



(vi) dziarzynskii, Hske. (figured). — A combination of the two 

 preceding. 



The illustrations of (ii) and (vi) on Plates I and II are 

 excellent. 



Dr. Reverdin has also most kindly drawn my attention to 

 the list of the several Swiss forms enumerated by Herr Yorbrodt,t 

 with a coloured plate of Antbrocerid alierrations conceived on 

 the same lines as by Courvoisier on the Lycfenids — one series of 

 names for the several species of the genus, the same names 

 being applied to corresponding aberrations of each species. The 

 following aberrations have been met with in Switzerland according 

 to Herr Vorbrodt : 



(i) costali-elongata {= the cuneata form of Tutt) ; (ii) anali- 

 eloiifiata ; (iii) apicali-elongata ; (iv) hasi-conjiiiens ; (v) costali- 

 confiuens ; (vi) anali-confinens ; (vii) parallela {^ conflmns, Dz. 

 = dziurzynskii, Hske.); (viii) apicali-macidata; and (ix) quadri- 

 inaculata (— hlaclderi, Dz.). In the supplement to the same work, 

 in addition to these aberrations, we have (x) sexmaculata, and 

 another, (xi) parallela, differing, however, from the (vii) pai^allela 

 mentioned in the fascicule. 



In this supplement also appears, as a variety, alpestris, 

 Burgeff, the usual form of the Swiss Alps t 



To the colour aberrations or forms may be added : 



(j) Ab. carnea, de Saussure ('Bull, Soc. Lepid. Geneve,' 1914, 



* Escorted by M. C. Obevthiif from Cauterets, Htes. -Pyrenees (and ' Eut. 

 Eecord.' vol. xii, March, 1900, p. 80), as a form of tristis.

 vol. ii, 1913.
