INSECTA, HYMENOPTEllA. 
glyphic inscriptions are obliterated by being filled with mud by this species 
in making its nests ; Pr. E. Soc. 1871, p. v. 
Polistes gallica and diadema. For very extended observations upon the oc- 
currence in and influence of parthenogenesis on these insects (considered 
races of one species), cf. v. Siebold, Beitrage &c. pp. 1-101, pi. i. These are 
too long for extraction or useful abstraction ; but the author’s final conclu- 
sions are : — 1, that the unimpregnated ova bring with themselves from the 
ovary the capacity of producing male individuals ; 2, that such males are de- 
veloped by inherent property, and independently of external male influence ; 
3, that, under the influence of male spermatozoa, such ova are capable of 
changing their faculty of producing only males, and can develop female indi- 
viduals. 
Vespa holsatica. For short observations upon parthenogenesis in this 
species, cf. id. 1. c. pp. 102-105. 
Vespa crahro. Smith (/. c*. p. vii) corroborates P^aumur’s mention of a 
habit in this species of removing bark from small branches, and thinks the 
insect in that case is endeavouring to extract sap as food, and not to obtain 
material for its nest.
