Ratio of eyes AME :ALE : :PME :PLE = 10:61:6:7. AME separ- 
ated from one another by about three fifths of their diameter, from 
ALE by only a line. PME separated from one another by about five 
sixths of their diameter, from PLE by about the same distance. LE 
almost in contact. Central ocular quadrangle wider in front than 
behind in ratio of about 6 :5 ; nearly as long as wide in front. Clypeus 
very high; height equal to nearly three times the diameter of AME.
