Renter notes (Acta Soc. F. F. F., ix., p. 20) that previous to 1893, A. 

 meliloti had been confused with A. trifolii, both species having stood in 

 northern collections under the latter name. Aurivillius states that the 

 subcostal nervure of the hind- wing in A. meliloti is " a short central 

 piece, united with the first median nervure," but this character appears 

 to be very variable. Specimens sent by Reuter to Aurivillius were 

 returned by the latter with the remark that German and south European 

 A. trifolii were much larger than Finnish examples, and more like A. 

 lonicerae, and that A. meliloti was difficult to separate from the small 

 A. trifolii. Reuter, after further investigation, came to the conclusion 

 that both species occurred in Finland, A. meliloti being, however, 

 much more local than A. trifolii. The occurrence of the true A. meliloti 

 in Finland was first discovered by Ehnberg. It has been taken at 

 Fagervik, July llth, 1890, Kuhmois, July 21st, 1882. 



f. var. confusa, Staud., " Stett. Ent. Zeit.," xlii., p. 398 (1881). Haberhauer 

 sent me in two years abont 200 specimens of this species, doubtless all from the 

 Ala Tau. A small number of the specimens were typical A. meliloti, with 5 isolated 

 red spots, but, in the greater part, the spots are confluent, often only the two 

 outer and upper (3 and 5), often only the two lower (2 and 4), and specimens are 

 by no means rare in which the spots are as confluent as those of A. purpnndi* 

 (pilosdlae) or A. brizae. Since the specimens with confluent spots formed by far 



the great number the race may be designated as var. confusa 



In occasional examples the fore-wings are almost entirely red, with dark margins. 



Lederer received one similar to these last from the Altai, and we received 



no female with 5 isolated red spots from the Ala Tau.

Christ first associated [Mitt. Sch. Ent. Ges., vi., p. 40 (1880)] A. 

 charon with A. viciae (meliloti). He noted that in size A. charon 

 averaged from 1-2 mm. less in wing expanse, was of brighter colour 

 (red and green), had sometimes a well-developed abdominal red belt, 

 had a sixth spot varying in size and development, and possessed a 

 distinct peculiarity in the broader black border (the red entering it 

 and forming a rectangular patch at the anal angle). He expressed a 

 suspicion, however, that charon was only a south- Alpine form of A. 

 meliloti, as he had seen: (1) Red-belted German meliloti from Wasseln- 

 heim, Alsace and Kreuznach. (2) Alpine A. meliloti with broader 

 margin to hind-wings and of similar form to charon. (3) Narrow- 

 bordered charon bred from Tyrol larvae in 1877. Frey notes [Mitt. 

 Sch. Ent. Ges. t vii., p. 14 (1887)] the occurrence of charon, Hb., on
