The earliest experiments with E. limacina showed that virgin females 

 deposit eggs that hatch, but that the larvae never survived more than 

 a few days. The author's recent investigation has, however, established 

 the fact that the eggs deposited by spring-brood virgin females hatch 

 and produce normal vigorous larvae, which feed normally, pupate, and 

 finally produce adults, which are females only. Parthenogenesis, 

 when continued in the offspring of this second or summer brood of 

 adults, gave larvae of which a great number failed to pupate, the 

 remainder pupating and either failing to transform into the adult stage, 

 or failing to emerge from the enclosing earthen cells. 



An orchard heavily infested with spring-brood females sustained 

 such injury that several cherry trees were killed outright, owing to 

 the enormous number of second-brood females and their second-brood 

 larvae pai-thenogenetically produced. The following spring, however, 

 saw the emergence of only a very few adults, probably ownng to a lack 

 of vigour due to the absence of fertilisation, though possibly due also 

 to unknown causes.

Many authors have recorded the fact that many Aphid- destroying 

 species of CoccinelUds may become phytophagous even to the extent 

 of being injurious to vegetation. Examination of the intestinal 

 contents has shown that various species of these insects feed 

 indifferently on Ai-thropods, pollen grains and spores of fungi. It has 

 more recently been found that Halyzia {Thea) vigintiduojjunctafa, L., 

 and H. {Vibidia) duodecimguUata, Pod., have similar habits, which the 

 author has also shown to be the case with H. sexdecimguttata, L. At 

 Montpelher, these three species feed on Phyllactinia suffidta, a widely 

 distributed fungus that attacks the lower surface of the leaves of hazel, 

 ash, and Cornus sanguinea.

The Muscids described in this paper are Hyperecteina polyphyllae, 

 sp. n., found feeding in the larval state on the dead bodies of the 

 Lamellicorn beetle, Polyphylla fullo, L., in Russia, and Scatophaga 

 rufiventris, sp. n., parasitising the same beetle by laying its eggs on the 

 abdomen of the living insect.
