182 PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 
we have since issued a coloured plate showing the life-history. The eggs 
are laid in a mass on leaves and the larvee burrow in the stem. Some- 
times practically every plant ina field may be bored, often by many larve. 
As regards control, the collection of egg-masses and destruction of affec- 
ted plants are not practicable measures on a field-scale. Destruction of 
stubble, promptly after harvest, may prove effective but, before advo- 
cating this, we require further investigation of the species—whether 
the larve in the stubble carry over parasites and so on. Another point 
concerns the use of the juar stalks as fodder ; we require to know how 
long these stalks are capable of containing Chilo in any stage and, if 
there is danger from this source, whether any other method of storage 
of this fodder can be used. As I pointed out in my opening address, 
Chilo is one of the insects which we have found is capable, at Pusa, of 
continuing in a resting condition and emerging at irregular intervals 
over a comparatively long period of time. But such conditions will 
probably vary locally. 
As regards parasites, an undescribed species of Trichogramma attacks 
the eggs and is fairly common, the attacked eggs turning black. Xanth- 
opimpla punctata and Tarytia flavo-orbitalis are also recorded by Morley 
[Fauna of India, Hymenoptera, Vol. III, pp. 125, 507] as bred from 
Chilo simplex but it is uncertain whether the host was really Chilo or 
Diatrea. 
In Bombay Chilo simplex is abundant in juar. 
And in the Central Provinces also. 
The species of Diatrea have already been dealt with under sugarcane. 
So far as we can make out at present, the species of Diatrwa are the 
common borers in cane, occurring uncommonly in juar and maize, whilst 
Chilo simplex is the common borer in juar and maize and occurs occasion- 
allyincane. Dvatrcea does not seem to be common in juar andis probably 
of small importance as a pest of this crop. 
Papua depressella has been reared from juar at Lyallpur but is a mere 
casual visitor in this crop. 
Sesamia inferens occurs throughout India and is usually a minor 
pest of guar. The larvee are often found in large numbers in the stubble 
and may be destroyed there. 
The flower-heads of juar are attacked by several Cetoniad and Meloid 
beetles. A long list of these insects could be prepared but we need only 
consider a few common ones and those of which we have records are :— 
Heterorrhina elegans, Anthracophora atromaculata, and Protetia 
alboguttata, all found in small numbers at Coimbatore ; Anatona stillata 
[‘ South Indian Insects,’’ p. 282, fig. 122] at Bellary and Bangalore ; 
Oxycetonia versicolor [l.c. p. 284, fig. 123] in Southern India ; Chiloloba
