locusts, the author having found it in places in which D. maroccanus 

 was unkno\\^l and C. italicns rare. Egg-masses o{ D. maroccanus, 

 collected in winter on the lower slopes of the Madonian Mountains, 

 were found to be infested by Mylabris and Cytherea. 



Attention is drawn to the failure in the field of Empusa {Ento- 

 mophthora) grylli, although laboratory experiments were successful ; 

 in the open the fungus only attacks the insects after their life-cycle 

 is complete. Detailed descriptions are given, with figures of the 

 various parasitic insects referred to above ; the question as to how 

 far they may be made use of in practice is discussed, the opinion being 

 expressed that they are at least worthy of further study and experi- 

 ment. A classified list of animal and fungus parasites is given in 

 tabular form and a summary of the answers received to nine questions 

 on the subject of locusts, their ravages and mode of suppression, 

 submitted by the International Institute of Agriculture.

This report covers a period of 11 months to 14th September. The 

 principal insect pest during the year was Anisoplia austriaca, Herbst, 

 an outbreak of which occurred in the southern part of the government, 

 while only single specimens were noticed in the northern part. The 

 pests were observed in the south on 10th June, but probably really 

 appeared some days earlier. Handpicking was carried out as a remedy. 

 Winter-sown wheat was damaged in some localities by Mayetiola 

 destructor, Say, in autumn, but the crops recovered in spring. Cephus 

 pygmaeus, L., was found as usual, nearly everywhere. Epicometis 

 hirta, Poda, appeared in small numbers, as was also the case last year 

 after a few years of outbreaks. Oscinis frit, L., was observed in small 

 quantities on barley and oats in the northern parts of the government. 

 Pentodon monodon, F., injured maize in June on one estate of the 

 district of Cherson. The larvae of Athalia spinarum, F., did consider- 

 able damage to winter-sown rape in the north-western part of the 

 district of Alexandrisk in August 1914. Adelphocoris lineolatus, Goeze, 

 was observed on lucerne in one locality of the district of Ananjev. 

 Phlyctaenodes sticticalis, L., the caterpillars of which caused great 

 damage last year, were practically absent this year. Otiorrhynchus 

 ligustici, L., has damaged roots of lucerne in one locality of the district 

 of Cherson. In fact, but for the outbreak of Anisoplia austriaca, the 

 year was very favourable as far as insect pests were concerned. 



As regards orchard pests the following are reported : Euproctis 

 chrysorrhoea, L., Malacosoma neustria, L., Cydia pomonella, L., 

 Acronycta tridens, Schiff., Hyponomeuta malinellus, Zell., and 

 H. variabilis, Zell., all of which appear yearly in more or less great 

 numbers. Lepidosaphes idmi {Mytilaspis pomorum) was noticed for 

 the first time. Gooseberries in the district of Cherson were damaged 

 by Bryohia ribis, Thomas. Chermes were observed on pines in Cherson, 

 in which town Psylla piricola, Forst., was also found. On old roots
