not important, except in one village, where about 270 acres of crops 

 were destroyed. In 1912 a great outbreak occurred in five districts 

 and about 54,000 acres of crops were destroyed, some 74,500 acres 

 more being injured, and the total damage being estimated at nearly 

 £125,000. In 1913, the moth appeared again in five districts, one of 

 which had been free in the pre\nous year. Crops began to be damaged 

 at the end of April and beginning of May, the larvae first attacking 

 the stems and then, from 1st to 28th June, the ears ; pupation reached 

 a maximum about 1st July. The first adults appeared in the open 

 on 7th July and disappeared on 7th August. The examination of 

 the weeds showed that they were heavily infested with eggs. No 

 eggs were observed on the stubble of grain crops, nor on weeds other 

 than Graminaceae. Several species of Hymenopterous and Dipterous 

 parasites were noticed but have not yet been identified. Winter as 

 well as summer sown crops were damaged, also Avenafatua, L. Barley 

 suffered less than wheat and mostly recovered from its injuries. 



As regards remedies, 0. musculosa belongs to the small group of 

 insect pests which each owTier can successfully fight on his own fields 

 whether his neighbours do so or not, being thus very different from 

 Pyrausta 7nibilalis, Hb. The folloT\'ing measures are recommended : — 

 Frequent and repeated moA\ing of weeds on fallow fields, roadsides, 

 boundary strips, etc. ; collection and burning of stubble after the 

 harvest ; deep ploughing in autumn with a disk plough. Where such 

 remedies have not been applied, only such crops as are proof against 

 this pest should be sown, viz. : — maize, sunflower, potatoes, millet, 

 and bachza plants.

The cotton stainers, Dysdercus andreae and D. delauneyi, reported 

 to have been prevalent early in 1913, were remarkably scarce early 

 in 1914, and experience shows that they usually occur in July, August 

 or September. A small Arachnid was found to be parasitic upon 

 them, but observations made in December showed that less than 

 20 per cent, were thus attacked. A weevil, Euscepes, batatae attacks 

 the leaves and stems of sweet-potato plants, though little damage is 

 done to the tubers. Sweet-potatoes should not be planted for some 

 time on land that has been badly infested and cuttings should only 

 be taken from healthv tubers.

This paper records the rapid and successful control of Aulacaspis 

 pentagona by Prospaltella berlesei in the Province of Udine (Venetia), 

 where the cultivation of the mulberry had suffered very considerable 

 injury up to 1909.
