acuta [l.c., p. 284, fig. 124] in South India and Nagpur ; Lytta tenwicollis 
[l.c., p. 303, fig. 148] in South India and Surat. Most of these beetles 
not only devour the pollen but also bore into and feed on the young 
erains, and may do considerable damage in local areas. They may be 
collected by hand or in hand-nets. 
These beetles lead us on to the group of insects which especially 
attack the ear-heads of yuar. Of these we know :— 
Stenachrova elongella. 
Sitotroga cerealella. 
Cecidomyiad Flies. 
Stenachroia elongella |“ South Indian Insects,” p. 421, fig. 296] has 
been recorded in Madras from larvee found on cholain ear-heads at Coim- 
batore and Hagari (Bellary), and at Pusa from larve on juar ear-heads 
and stems, maize cobs and marua ear-heads. The caterpillar webs over 
the ear-heads, in which it feeds, and is a sporadic pest of jwar in Madras 
and Bihar, but apparently is not known in Western or Northern India. 
It probably occurs in Burma also, but I cannot say definitely whether Mr. Shroff. 
it is this species. 
Sitotroga cerealella |‘ South Indian Insects,” p. 456, fig. 331] occurs Mr. Fletcher. 
throughout India, Burma and Ceylon as a pest of stored grains. It 
also occurs in the field on ripe ears of juar, paddy, etc., and, though 
hardly a pest in the field, it may thus be brought into stores with the 
erain, and we must therefore not overlook its occurrence on the plants 
in the field. 
The Cecidomyiad Fles occurring in juar heads have not yet been 
identified and perhaps more than one species may be concerned. In 
Madras a Cecidomyiad, found hitherto at Coimbatore and Udumalpet, 
attacks cholam, the egg being thrust in under the glumes when the seeds 
are about half-ripe and the larva boring in the seeds of the plants in the 
field, so that the damage done may be considerable. In Bombay there is 
a Cecidomyiad on juar whichis probably distinct from the species found im 
Madras. Anyway, its habits are different, as in the Bombay Cecidomyiad 
the flowers are attacked and the grain is not developed. For the sake of 
convenience, pending proper identification, we may call the Madras 
insect the “‘ Cholam Cecidomyiad ” and the Bombay insect the “ Juar 
Cecidomyiad.”’ We lately received some specimens of the latter insect 
from Poona, collected in December 1906, and it appears that the ovary 
of the juar flower is destroyed by the Cecidomyiad grub, which pupates 
inside, the result being that no grain is developed. These Poona speci- 
mens were extensively parasitized by a Chalcidid. 
The Cecidomyiadee is a family of which very little is known in India 
as yet, at least as regards their capabilities as crop-pests. The species
