DU BuYSsoN (H.). Observations diverses : Cheiniatobia brumata, L. — 

 Miscellania Entomological Narbonne, xxiv, no. 1, December 1917, 

 pp. 6-7. 



For several seasons the winter moth, Cheimatobia bnimata, has 

 destroyed the apple crop at Veyre and Chanonat, while the caterpillars 

 of Hypoiomeuta euonymellus, L., also did great damage for a time in 

 the orchards of Montferrand and Gerzat. In the case of C. brumata 

 the use of adhesive bands on the tree-trunks at suitable times gave 

 good results, by preventing oviposition and trapping the females.

This paper chiefly deals with Chalcids found in the Province of 

 Madrid and was originally read in 1915 before the Spanish Association 

 for the Progress of Science, but as here given it contains additional 

 data collected up to 30th September 1917. 



The citrus scale, Chrysomphalus dictyospermi, Morg., is attacked by 

 the Aphelinids, Aphelinns chrysomphali, Mercet, Aspidiotiphagus 

 citrinus, Craw, the Encyrtids, Aphycus flavus, Mercet, SignipJiora 

 werceti, Malen., and the Mymarid, Parvulinus aurantii, Mercet 

 {Paralaptus torquatus, Malen.), as well as by the Coccinellid, Chilocorus 

 bipustulatns. 



Lepidosapkes citricola, L. ghveri and a species of Parlatoria that also 

 infests citrus plants, are parasitised by Apkelinus mytilaspidis, Baron, 

 and .4. maculicornis, Masi. 



Lymantria {Portkefria) dispar, L., is controlled by the Encyrtid, 

 Schedius kuvanae. How., the Eupelmid, Ana status bifasciatus, Fonsc, 

 and the Eulophid, Atoposomoidea ogitnae, How. The olive moth, Prays 

 oleellus, and the apple ermine moth, Hyponomeuta malinellus, are 

 parasitised by the Enc\T:tid, Agenaspis fuscicollis, Dalm., and by the 

 Elasmid, Elasmus flabellatus, Fonsc. Ckionaspis pinifoliae has a 

 number of enemies in the Province of Madrid, including the Aphelinids, 

 ProspaUeUa leucaspidis and Azotus pinifoliae, and the Encyrtids, 

 Aphycus pinicola, Signiphora conjugalis and Walerstonia prima. 



The vine moths, Polychrosis botratia, Schiff., and Clysia (Gonchylis) 

 ambiguella, Hb., are parasitised by Oophthora semblidis, Aur., Elasmus 

 flabellatus, Fonsc, and Chalcis pusilla, Rossi. There are numerous 

 natural enemies of the caterpillars of Cnethocampa processionea, 

 C. pithyocampa and Cydia pomotiella, and of the many scale-insects 

 injurious to fruit and other trees. The pear Cecidomyid [Perrisia 

 pyri] is attacked by a Proctrotrupid, Inostemtna piricola. 



A list is given of 11 genera of Aphelinids and 30 of Encyrtids at 

 present known in Spain, the former including 26 species and the latter, 

 77 species. The author intends to publish a monograph on the 

 Encyrtids of Spain, the species recorded being about 200 ; the total 

 number of species of Chalcids 'in the Peninsula is believed to be 

 about 2,000.
