dissecting microscope and a drawing tube at about X 88. The draw- 
ings then were superimposed in such a way that they all were of the 
same size and overlapped to a maximal degree (Fig. 5). However, 
sizes and profiles of the petioli are varying within each population 
so much that a clear distinction of populations by this character is 
impossible. Even between E. kraussei and E. ravouxi we could not 
find any reliable differences in the petiolar outlines. The character, 
therefore, is useless for taxonomical purposes in the Epimyrma spe- 
cies investigated, and it can neither support nor contradict a syn- 
onymization of E.f and E.v. with E. kraussei. 
Karyology 
Karyotypes were studied using the air-drying technique of Imai et 
al. (1977). Usually we made preparations from testes of $ pupae, 
and a few from cerebral ganglia of prepupae. E. kraussei from sev- 
eral populations (pop. no. 1, 5b, 6, 7, 9, 12a) and E. vandeli (pop. 
no. 5a) were checked, whereas no preparations of E. foreli could be 
made. 
A total of 215 metaphase cells of 16 E. kraussei-$ pupae from 8 
colonies of 6 different localities showed 10 chromosomes each (Fig. 
6). 6 cells had 9 chromosomes, and 5 cells had the diploid number of
