identified. A^arin is enemies, such as the larvae of Coccinelhds, 

 Chrysopids, Syrphids and certain species of Aphidius, are known to 

 exercise some control over them and the author is studying this 

 group of Braconids with the object of effecting an interchange of 

 parasites. As an insecticide for use against Aphicls, Bordeaux mixture 

 is suggested.

While it might be expected that Chili would contain representatives 

 of all the families of Hymenoptera, no Mymarid has previously been 

 observed west of the Andes. The author describes in this paper 

 Anagnts, porteri, sp. n., from a single exa;mple taken near Santiago in 

 1916.

Very little is kno^\^l of the habits of the E vaniids, Pristaulacus spp. , 

 and of the species found in France. P. patrati, Serv., P. latreillanus, 

 Nees, and P. gloriator, F., have been previously recorded ; to these 

 the authors add P. bimaculatus, Kieff., P. schlettereri, Kieff., and 

 P. cJdapovskii, Kieff. The last-named emerged in July and, less abund- 

 antly, in August and September, from branches of fig, evergreen 

 oak and mllow, all of which were infested with Clytus pilosus, Forst. 

 {glahromacidatus, Goeze). It therefore seems, as far as is known, to 

 be an exclusive parasite of this Longicorn. P. bimacnlatus is recorded 

 as having been reared from Purpuricenus koehleri, and it is considered 

 probable that P. schlettereri is also a parasite of Longicorns. P. jmtrati 

 is known to be a parasite of Xiphydria. It is not known whether 

 one species can attack both Coleoptera and xylophagous Hymenoptera, 

 though indications rather point to the contrary. 



Keilin (D.). Sur quelques Modes particuliers de Resistance des Larves 

 de Dipteres centre la Desiccation. [Some special Means of Resis- 

 tance to Desiccation shown by Dipterous Larvae.] — Bull. Soc. 

 Entom. de France, Paris, no. 5, 13th March, 1918, pp. 102-104. 



The method of resistance to desiccation shown by Dipterous larvae 

 varies in the different groups. Larvae of Ceroplatus protect 

 themselves by spinning a coarse web made by a salivary secretion 

 of the moijth ; under this the larval and nymphal stages are passed. 

 Moisture is obtained during these stages by rubbing against the 

 hydroscopic threads of the web, which absorb moisture from the air. 

 If removed from under the web, the larvae either begin at once to 

 spin a fresh one, or die by desiccation. Larvae of MycetophiHds and 

 Sciophilids are protected in a similar manner. The larvae of Phronia 

 sp,, which often accompany Ceroplatus tipidoides, F., secrete a thick
