is comparatively large in size and pale pinkish -brown in 



colour. 



9. Andropogon pertusus. — This grass is extremely common 



in the pasture grounds of the Central Farm, Coimbatore. On 

 careful examination, small-sized galls were found in small num- 

 bers on these plants. The fly, which has been reared out, resem- 

 bles the gall-fly on Andropogon schoenanthus in general appear- 

 ance, but is smaller in size. 



10. Apluda varia. — This is a slender red-stemmed, tall- 

 growing grass commonly found among prickly pear bushes and 

 along the banks of water-courses and canals. Galls were first 

 noted in this grass at Samalkota in October 1916, but flies 

 could not be reared. In November, galls were found abundantly 

 on this grass at Coimbatore. They are slender, elongate struc- 

 tures of violet-brown colour and generally covered with a whitish 

 bloom. The tip is surmounted usually by an undeveloped leaf. 

 In some cases flower buds in the ear-heads were found trans- 

 formed into galls. The fly is slightly smaller, slenderer and 

 darker than the one reared from A. schoenanthus. These galls 

 were also found at the foot of the Xilgiris at Kallar. 



11-13. Iseilema spp. — A few galls were noted on Iseilema 

 anthephoroides at Pattikonda, Kurnool District, in September 

 1916. Flies not reared. Old galls were noted at Samalkota on 

 Iseilema laxum. At Palur. S. Arcot District, a few galls were 

 found on a grass very like Iseilema, but which could not be 

 identified on account of the inflorescence not having been found. 

 Two flies were reared, of which one has been sent for identifica- 

 tion. 



14. Ophiurus corymbosus. — A tall erect grass with brittle 

 stems, growing in thick clumps in moist depressions at Patti- 

 konda, Kurnool District. Galls were found in side shoot 

 arising from the collar region and sometimes higher up the stem. 

 Young shoots coming up from the underground stems were alsvO 

 infested and showed specially thick and stout formations. 

 Flies were not reared. 



15. Oryza saliva (wild paddy).— This was found growing 

 luxuriantly in depressions along the railway line at Samalkota. 

 bilver-shoots were common, but flies eouid not be reared out 

 owing to heavy parasitisation. 



16. Iscliaemum pilosum .—The road from Adoni to Siru- 

 guppa traverses a vast stretch of undulating black soil country, 

 lhehelds of indifferent cultivators in these black soils are gene- 

 rally infested with "Kundara gaddi" (Teluga)—Ischaemum 

 pilasum—B, grass with a system of spreading under-ground stems 

 —proving as bad a weed as " Hariali " (Cvnodon) or Nuttgrass
