 Parasite of Hypoborus ficus ET.]~Bidl. Soc. Entom. France, Paris,

This paper deals with a new Braconid genus, Sycosoter, closely- 

 allied to Ecphylus, Forst., in structure, but differing from it in having 

 both winged and apterous forms of both sexes. S. lavagnei, sp. n., is 

 an external parasite of the larva of Hypoborus ficus, on which the egg 

 is laid through the bark of the fig-tree, the emerging larva spinning a 

 cocoon in the gallery of the host, there being apparently the same 

 number of generations of host and parasite. The females in spring 

 are almost all winged ; those in the autumn are more often wingless, 

 while winged males occur more rarely than wingless ones, even in 

 spring. At first it was thought that this condition might be due to the 

 shedding of the wings, but the examination of numerous, newly 

 emerged examples has established the fact that this is not the case,

 sillonn§ {Otiorrhynchus sulcafus, Fabr.). [On the Parthenogenetic 

 Reproduction of Otiorrhynchus sulcatus, F.]. — C. R. Hebdom. Acad. 

 Sciences, Paris, clxv, no. 22, 26th November 1917, pp. 767-769. 



Normal parthenogenetic reproduction is rare among the Coleoptera, 

 though it has been recorded in three species of Otiorrhynchus, namely, 

 0. turca, Boh., 0. cribricollis, Gyll., and 0. ligustici, L. Hitherto 

 0. sulcatus has been regarded as a species exhibiting constant sexual 

 reproduction, but the severe infestations of vineyards during recent 

 years having furnished abundant apportunity for observations both 

 in the field and the laboratory, where more than 3,000 individuals were 

 dissected without the discovery of a single male, the conclusion has 

 been reached that the existence of males, though possible, is extremely 

 rare and sporadic in certain generations. 



From a practical point of view, this is a fact of the utmost importance, 

 since all the individuals being females, and each one capable of laying 

 150 eggs, an infestation develops with the greatest rapidity unless 

 energetic steps are immediately taken to control it.

This paper urges the protection of all those species of small birds 

 that have proved their usefulness in destroying the larvae of vine- 

 moths in the vine-growing districts of France.
