natural control. An especially important paper by Borcea relates to 

 the damage caused by Bostrychid beetles in Rumania. Mr. Suster has 

 published a very important work on the Tachinidae of Rumania. 



The manuscript report referred to in the opening sentence of the 

 preceding paragraph has been published since that paragraph was 

 written. Today (April i8, 1930) I have received from Professor 

 Borcea Parts i and 2 of Volume 16 of the Scientific Annals of the 

 University of Jassy, and this particular paper is published on pages 

 263 to 276. To this paper is added a list of certain publications that 

 consider the entomological fauna of Rumania and the insects injuri- 

 ous to agriculture. It is not a long list, but it includes mention of 

 several papers of importance. Most of those relating to injurious 

 insects have been written by Professor Borcea and Professor Fin- 

 tescu. There is also published in the same volume a very interesting 

 report by Professor Borcea and Mr. Suster on the ravages caused 

 in Rumania by the Russian caterpillar (Loxostege stictkalis). The 

 article includes a consideration of its natural enemies and the means 

 employed to combat the insect. Mr. Suster's long and fine paper on 

 the Tachnidae is printed in the same volume. 



BULGARIA 



The i>ests of cultivated crops in Bulgaria apparently do not dififer 

 strikingly in character from those of surrounding countries. The Bul- 

 garian Society of Naturalists in 1914 published in its Memoirs two 

 articles by Iv. Bouresch on the nocturnal Lepidoptera of Bulgaria with 

 especial reference to injurious species, and in 1919 the Journal of the 

 Bulgarian Academy of Sciences published an article by D. Iltschew 

 on Deilephila norii and the damage done by it. Later there existed an 

 Institute for Agronomical Research at Sofia which published a 

 Review ; and in 1921 in this Review there was an article on one of the 

 sawflies in the plantations of pines by D. loakimov. There was a 

 distinct entomological section to this Institute, and reports were pub- 

 lished in 1923 and 1924 by Dr. P. Tschorbadjieff (spelled in the Re- 

 view of Applied Entomology Chorbadzhiev). In 1928 an article by 

 I v. Georgieff on the vine moth in Bulgaria was published, and in 1927 

 a report on forest insects by M. D. Ruskov was printed in which 

 63 forest pests were recorded. Other articles on injurious insects 

 have been written by Bouresch and by A. K. Dryenowski. 



Doctor Tschorbadjieff published a series of articles on injurious 

 insects of Bulgaria in the years 1924 to 1927, and there was estab- 

 lished (the exact date is not known to me) an luitomological Section 

 of the Central Experiment and Control Agricultural Station in Sofia.
