mentions the fact that the anteapical teeth are not on a 
level. In the specimens seen here the ciliate setae can be 
seen on the dens but not the legs while the teeth may or 
may not be level. In addition there is the variation in the 
structure of the p.a.o. not mentioned before. When we 
combine this with the well known local variability of the 
pattern in viridis I feel it best to consider turkestanica and 
the present form part of the locally variable widespread 
/. viridis. 
In the region it has been found only from the Lebanon 
Mountains : Lebanon : B’Charra Cedars, v ’53 ; Vic. Har- 
risa, xi ’52 ; Ain Z’Halte Cedars, vn ’52 & xi ’52. Cassagnau 
& Delamare reported it from Chebaa and Handschin from 
several localities in Palestine.

The specimens agree well with available descriptions 
of European forms identified as this species, A number of 
minor differences are seen: there are frequently no ciliate 
macrochaetae on the third abdominal segment, and the 
corner tooth on the last two pairs of empodial appendages 
is absent in about 85% of the animals. The patterns are 
varied. Distribution: Lebanon: 2 km. S. Saida, xi ’53;
