186 PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 
field of guar may be covered with this Mite and control on a field scale 
seems rather out of the question. 
The roots of guar are attacked by a subterranean Aphid which has 
been found at Poona and is probably widely distributed, but we seem 
to know very little about it. 
On the Coimbatore Farm Cockchafer grubs were noticed to do a good 
deal of damage to roots of cholam plants in 1916. 
Basra (Pennisetum typhoideum). 
| Cumbu—Madras. | 
The pests of bajra are very similar to those of jwar so it will not take 
us long to run through the list. 
Bajra seedlings are attacked by :— 
Chrotogonus spp. 
Epacromia tamulus. 
Tanymecus indicus. 
Anthomyiad Fly. 
Chrotogonus spp., Epacromia tamulus and Tanymecus indicus attack 
young bajra plants in the same way as they do other young plants and 
there is nothing special to say about them as regards bajra. 
The Anthomyiad Fly attacking cwmbu seedlings has been noticed 
in Madras and separated by Mr. Ballard as a species distinct from the 
cholam stem-fly. Its larva in cumbu bores both in young and old plants, 
in the stem and (characteristically) in the ear-head, in which it bores in 
corkscrew fashion. So far, this fly seems to be known only from Madras, 
but is probably widely distributed in India. Control should be as in 
cholam stem-ily. 
The insects found eating the leaves of bajra inciude :— 
Flea Beetles. 
Colemania sphenarioides. 
Orthacris sp. 
Estigmene lactinea. 
Amsacta mooret. 
»,  albistriga. 
Marasmia trapezalis. 
Eyisomus lacerta. 
Myllocerus 11-pustulatus. 
Flea-beetles are sometimes found in some numbers on bajra-leaves, 
but it is impossible at present to identify these beetles. Probably many
