RIIOPALOCERA Nl MONICA, 



58. Lycsena euphemus, Hb. (Pi- 5- fi s- 4<\, 4.) 



L. kazamoto, Dnice. 



Localities Fuji-sail, NikUo, Asama yama, Yezo. 

 Time of appearance August. 



This is a mountain insect, and is very variable. Some specimens are all brown, in others blue pre- 

 dominates. 



59- Lyc&na iburiensis, But. (Pi. 5, fig. 5.) 



Localities Nanibii, Asama-yama. 



I have only two very worn specimens from Nambu, and one good specimen from Asama-yama. 



Concerning the LYC/NID^, there are some very interesting points which may be here mentioned. 

 The first is the remarkable difference between the colour of the sexes of many of the species, forming this 

 group, and I have drawn up a table under the following headings illustrating this fact : 



1. Both sexes alike dull. 



Miletus liamada (2) 

 Thecla attilia (i) 



Thecla eufhea (i) 



Thecla w-albttm (i) 

 Tliecla pruni (i) 



Thecla mera ( i ) 



Thecla ibara (i) 



Thecla butleri (i) 



2. Male sligluly colored, female dull. 



Niphandafusca (?) 

 Lycama euphemus (?) 



3. Male bright, female dull. 



Curetis, acuta (i) 

 Lyccena argiades (2) 

 Lyccena argia (2) 



Lyccena argus (2) 

 Lyccena cegon (?) 



Lyccena iburiensis (?) 



4. Male very brilliant, female dull. 



Thecla sapharina (l) 

 Th ecla japo n tea ( I ) 

 Thecla orientalis (l) 

 Thecla smaragditia (l) 



Some of the species do not always conform to their respective headings. There are bright and dull 

 female polymorphic forms of Thecla japonica, and temperature forms of others, such as Polyommatus 

 phlxas, the male of which becomes nearly black in the summer, and Lycxna euphemus, specimens 

 of which from Yezo are bright, especially the males. 



5. Male bright, female also bright, but in a less degree. 



Thecla orsedice (?) 

 Lyccena argiolus (2) 

 Lyccena lycormas (?) 

 Lyccena bcetica (2) 



6. Female brighter than the male. 



Lyccena pryeri (l) 



7. Both sexes nearly equal amount of color. 



Lyccena ogasawaraensis (?) 

 Amblypodia japonica (l) 

 Amblypodia turbata (?) 

 Amblypodia loomisi (?) 



Thecla signata (?) 



Tliecla arata 

 Thecla frivaldszkyi 

 Polyommatus plilceas 



8. Both sexes equally beautiful. 



Dipsas saepestriata 

 Dipsas lutea 

 Dipsas jonasi
