566 General Notes. [July, 
ENTOMOLOGY.’ 
was shown to have a larger asexual dimorphic form (our €.¢ 
operatola) that develops in an autumnal pip-like gall formed be- 
tween the cupule and the fruit. Walsh had previously given good 
reasons for the belief that C. g-acicu/ata was the autumnal agamic 
dimorphous form of C. g-spongifica (Am. Entomologist 1, Pp. 330 
ff.), and Mr. H. F. Basset has, following Adler’s interesting Oe 
ments in Europe, suggested the probable dimorphic connection © 
several of our vernal galls which produce bisexual individuals 
with autumnal forms which produce larger, asexual flies. VT 
Adler continues his successful study and experiment in this direc- 
tion, and gives in the Zeitschrift fiir wissens. Zool, (Vol. XXXV, P- 
151), the results obtained so far in his researches, and the number 
of species in which the occurrence of dimorphic forms has — 
proven is already quite considerable. The following 1s 4 ee 
thereof, the name in the first column referring to the agamic, tha 
in the second to the bisexual generation:

19. Neuroter / = Spathegaster aprilinus ? 
Of Nos. 1-13, the Gist form. appears in March until May, 
and the sexual generation in May until July. In No. 14 the first” 
form appears in January until February, the second in May un 
Very remarkable is the fact that in some closely allied spe 
no alternate generation seem to occur. They are the following 
species: Aphil. 
albopunctatus.
