TABLE II. Mathigs, 1912-1913. 



This table is a continuation of that given for previous years, Journ. of Genetics, Vol. ni. 1913, 

 pp. 4, 5. Reference numbers of purely female families are given in italics ; those of families with at 

 least twice as many females as males in thick type. Since a number of larvae were dissected for 

 cytological examination, the figures in the 'Total Males' and 'Total Females' columns are often 

 larger than the sum of 'gross, males ' + 'lact. males,' etc. 



Iinagos 



1 The inverted ratio of gross. : lact. in males and females is noteworthy. 



2 Note two exceptional gross, females. 



3 Note great excess of lact. where equality is expected. Some larvae of '12.26 (2) were lost at 

 hatching. 



* The male and female lact. are unexplained exceptions. 



' The object of these experiments was to determine whether a male immediately descended from a 

 unisexual family might produce unisexual offspring by a wild female.
