PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 241 
Chetodacus ‘eirugineus ferrugineus was reared from peach at Myitkyina, 
Upper Burma, and also occurs in guava, loquat, mango and pomelo 
and is widely distributed in India, Burma and Ceylon. It does not 
seem to be an important pest of peach in India. 
Chetodacus ferrugineus dorsalis has been reared from peach at Taru, 
Peshawar District, and at Maymyo in Upper Burma, and is also distri- 
buted throughout India, Burma and Ceylon, attacking also loquat, 
mango, chilli, pomelo, guava, pear and Solanum verbascifo'ium. 
Chetodacus zonatus is the species which has been called persice and 
mangifere in India. It is probably the commonest and most des- 
tructive of the Fruitflies found in peaches and is known to attack peaches 
at Ranchi, Pusa, Pachmarhi and Peshawar. It also occurs in Southern 
India and has also been bred from fig, sapota, ripe bael fruit, fruits of 
Careya arborea, mango, and at Nagpur m white gourd (Lagenaria vul- 
garis) ; but this last record seems a little doubtful and is perhaps a case 
of mis-labelling. 
C. zonatus usua'ly appears at Pusa in the fruits which ripen towards 
the end of May, becoming worse a; the season advances, so that late- 
ripening fruits may be badly affected. At Peshawar, where the peach 
season commences about 10th June, there seems to be no trouble with 
Fruitfly maggots unti! about the middle of August, but thereafter prac- 
tically all the fruits are attacked. It would be interesting to have some 
exact cbservat ons on the occurrence of the flies, and the species con- 
cerned, in other loca ities. 
At Peshawar Chetodacus zonaius occurs only late in the peach season 
up to October. 
Chetodacus tuberculatus is a new species described by Professor 
Bezzi in his recent paper. It was bred from peaches from Taung-gyi 
and Myitkyina, in the Southern Shan States and in North Burma res- 
pectively, but is not known to occur outside of Burma. 
Cheiodacus correctus has been reared from peach at Pusa and also at 
Coimbatore from mango. y 
Chetodacus duplicaius is another new species described by Professor 
Bezzi from examples reared from peach at Pachmarhi, which is its 
only known locality at present. 
It is evident that we want to know more about these Fruitflies as 
regards the species concerned, their d’scrimination, life-histories and dis- 
tribution. Practically everything in the way of a Fruitfly bred from 
peaches has in the past been lumped together as “ Dacus persica,” but 
we now know that half-a-dozen species are concerned and it is quite 
possible that this fact may throw a little light on the occasional sporadic 
appearance of these flies in destructive numbers and also on problems
