Anthrax fenestratus, and a Mylabrid beetle, Mylahris (Zonabris) 

 schreibersi ; in south Russia, 20 species of Mylahris, 4 Meloid beetles, 

 Epicauta spp., and 3 Bombyliids, Mulio obscurus, Anasioechus 

 nitidnhis and Callostoma desertorum ; in Asia Minor, Callostoma 

 fuscipennc ; in North America, the Meloid beetles, Epicauta vittata 

 and Lvtta cvanipennis, and the Bombyliids, Systoechns oreas and 

 Aphoebantus mus. 



Of 2,443 parasite larvae noticed at Foggia in 1917 Mylabris was 

 represented by 21 per cent., Mulio by 40, and Systoechus by 39 ; in the 

 following year 24 per cent, of 1,197 larvae were those of Mylabris, 

 while the Bombyliids accounted for the remainder.

Gautier (C.) & Reil (P.). Complement de Description et Biologic 

 A'Apanteles rubecula, Marshall (Hym. Braconidae), parasite de 



Pieris rapae, L. (Lep. Pieridae). — Bull. Soc. Ent. France, Paris, 

 1921, no. 9, 11th May 1921, pp. 143-147. 



The Braconid, Apanteles rubecola, Mshl., is recorded as a parasite 

 of Pieris rapae in the Lyons district, and additional descriptions are 

 given supplementary to those previously given in England. Observa- 

 tions show that the parasite always attacks the young larva shortly 

 after it hatches, puncturing it several times, though more than one 

 parasite never emerges from one host. A. rubecola can breed 

 parthenogenetically and P. rapae is its exclusive host. In the I-yons 

 district the development of the parasite is complete in 10 or 12 days. 

 After another eight or nine days the adult emerges, the parasitised 

 larva dying three or four days later. 



Tetrastichus rapae, Wlk., occurs as a hyperparasite, and it is 

 possible that it attacks the larva of A . rubecola through the larval 

 skin of P. rapae.

As a result of experiments to determine the influence of cold and heat 

 on cockchafers [Melolontha], it was found that they can resist the coldest 

 temperature likely to occur in Lausanne. They burrow into the earth 

 to escape the cold, and at or below 0° C. [32° F.] they freeze, but become 

 active within an hour after removal from the cold chamber. Tempera- 

 tures below —8° C. [17*6° F.] are fatal. They are apparently more 

 susceptible to heat, as all individuals succumbed when exposed to a 

 temperature of 45° C. [113° F.] for eight hours.
