seemed to give 12 as the normal number. Counts of female 
somatic tissues seemed near this same number, the best prep- 
arations, coming from follicle cells of the ovary, giving counts 
of 13, 14, and 13, respectively. 
Wieman’s findings are unexpected, for among many Hy- 
men optera the males are haploid because they are produced 
parthenogenetically from eggs in which reduction has oc- 
curred, but the females are diploid because, if they are pro- 
duced parthenogenetically, they come from eggs in which re- 
duction has not occurred. Doncaster’s work (1910-1916) 
seems to confirm this general statement for the cynipid species 
Neuroterus baccarum, and Patterson (1928) accepts this as 
the explanation of the demonstrated fact that agamic Cyn- 
ipidae are apparently of two sorts : those that produce females 
only (because no reduction occurs), and those that produce 
males only (because reduction does occur). If Wieman’s re- 
sults are acceptable, they suggest that the bisexual female is 
haploid as well as the male, for even if the accuracy of the 
somatic count on erinacei is open to question, the count falls 
short of the expected 2X number of 24 chromosomes. Wie- 
man suggests that the slight difference between the male and 
female counts in this species is due to the presence of true 
sex chromosomes in the female. Either Doncaster or Wieman 
is wrong in the cytologic findings, or, if both are correct, 
there is more than one type of maturation involved with the 
alternation of generations of diverse species of Cynipidae. It 
is highly desirable that Wieman’s brief investigations be ex- 
tended by further work on erinacei.

FEMALE. — Highly variable insects, a hybrid population grading 
from typical wheeleri to typical pezomachoides in all characters, the 
average more nearly represented as follows: Head bright rufous with 
black over much of the front and on the median line of the face; the 
antennae black, varying from piceous on the first two segments to brown 
on the whole basal half of the antenna; the mesonotum bright rufous, 
the pronotum largely bright rufous laterally but black on the edge, the 
mesopleuron largely black with touches of rufo-piceous; the legs largely
