PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 305 
tab. 16, but it may be as well to add that the grubs are sometimes found 
boring in stems as well as in fruits. 
As regards control, we discussed that under Peach, but a special 
line of control with parasites of this species has been taken up in Hawaii, 
as I told you the other day. In India Chetodacus cucurbite appears to 
be parasitized to a remarkably small extent but, from larve collected 
at Pusa in fruits of Momordica charantia, we reared about fifteen per 
cent. of a small Braconid parasite which has been described by Professor 
Silvestri under the name Opius fletcheri [Boll. Lab. Zool. Portici x 
pp. 163-164, fig. 2]. Syntomosphyrum indicum, Silv. [7. c., IV, 232-344] 
was also found at Bangalore by Compere but is apparently not attached 
especially to Ch. cucurbite. 
I told you the other day about the visit of Mr. Fullaway to India in 
1915 especially to search for parasites of Ch. cucurbite with the purpose 
of introducing them into Hawaii. A short account of his journey is 
given in the Hawaiian Forester and Agriculturist for August 1916. 
Mr. Fullaway was in Bangalore from 17th November to 23rd December 
1915 and in that period he reared about 10,000 specimens of Ch. cucurbite, 
out of which Opius fletcheri came abundantly+as well as a small lot of 
Spalangia, but Syntomosphyrum indicum could not be rediscovered. 
After staying in Singapore and Manila, Mr. Fullaway eventually returned 
to Honolulu on 10th May 1916 with a small lot of living examples of 
this Opius and this has been bred successfully and liberated in Hawaii, 
as is shown by the fact that during the five months July to November 
1916 no less than 9,173 females and 5,361 males of O. fietcheri were reared 
in the insectary and of these numbers most were liberated. This attempt 
to procure parasites, therefore, was quite successful. Why Ch. cucurbite 
is not controlled more thoroughly by parasites in India is not apparent. 
We have not reared any hyperparasites, so the scarcity of the parasite 
is not likely to be due to this cause ; nor is it likely to be due to scarcity 
of food, as Ch. cucurbite is sufficiently abundant— in fact, only too 
abundant— everywhere. Yet, out of thousands of examples of Ch. 
cucurbite reared at Pusa we have found it decidedly the exception to 
secure material parasitized to any appreciable extent. It will be in- 
teresting and useful if the Provincial Entomological Staffs will collect 
Ch. cucurbite grubs and pupe in numbers and either send them to Pusa 
or breed them out, to see what parasites there are and in what propor- 
tions they are found. 
Dacus brevistylus is recorded from Madras, where it has been reared 
in melons at Coimbatore and Cuddapah and in water-melon at Hagari. 
It is probably more widely distributed, but overlooked.
